Hello guys, Just to let you all know I have been Talking with Tyberius, I am in awe at his project and have always wanted to build such a robotic machine since the days of seeing Johny five, I have ordered ALL the parts to build this machine and the modded parts also that tyberius has used in his J5. Tyberius has also been very helpful in ordering the Pico ITX parts for me ,as in NZ they are not available here and the company that sells them do not ship international. So when I get everything together I will post a detailed construction with photo's. Tyberius has given me permission to make a replica of his machine.Thank you.

Go man go! Like I said, I'm very flattered that you're building J5 a brother.

Your step by step photo builds are excellent, and something I should have considered when I built mine (unfortunately I was foaming at the mouth to get mine built asap, and ended up rebuilding/modding over a period of months)

Can't wait to see how this all turns out, your pico-itx + picoPSU arrived yesterday :D

Hey guys this is great, Thanks so much for all your help and enthusiasm in getting this project of the ground. Thank you also Tyberius for acquiring the PC parts needed for this project. M'mmm arrived eh, One step closer. Thanks. i can understand you foaming at the mouth to get it finished I think I would to, but have learnt that doing a detailed photo album as you go is invaluable but it also takes a lot of time and patience.

Jut arond the corner I too will be following 4mem8's J5 so we can have a huge family going here. I can't wait.. Plus I love what 4mem8 does with all his robots, I bow down to the master builder 4mem8.

I got to spend a lot of quality time with J5 yesterday - you're in for a treat when you birth his little brother. J5 was the hit of the Trossen Robotics booth, and *everyone* had to play with him. I swear he talked to, and tracked objects for, 500+ people in one day...

The modified design truly takes it several *really* big steps beyond the original concept. Grats!

4mem8
06-15-2008, 03:04 PM
Adrenalynn: He is great, and thank you for confirming that for me, Did you get to speak with Andrew? I would love to meet him! I must set up a video link through AIM and see him. I have spoken to him on numerous occasions through AIM. It would also be nice to set up Aim with you also if you wanted to!

Adrenalynn
06-15-2008, 03:09 PM
Yeah, we got to chat for a "few" minutes... :D

Seriously, we had some very lively discussion, both during the show and after. It was a blast getting to meet and interact with a handful of the "usual suspects".

DresnerRobotics
06-15-2008, 03:17 PM
Yup, we had 10 people out for drinks last night, very nerdy conversations at hand :D

It was a blast getting to meet everyone.

Adrenalynn was teaching me a few things about roborealm as well ;)

Adrenalynn
06-15-2008, 03:26 PM
I have a robo file for you, Andrew, with some additional processing that you might find useful for noise reduction (no custom dll required).

This file controls an SSC32 to drive a motor controller over PWM, is it's not plug-and-play, but if you have a look at thresholding and dilation you might find some applicability. Of course this is red-tuned to a laser right now...

Let me know if it's not self-explanatory!

Also, look at markers. You should be able to simultaneously track multiple blobs of multiple colors. So if someone picks up the red ball, it'll follow it, and if they pick up the green cube, it will still follow.

I have some pictures of it, but unfortunately I dont have my micro-usb cable with me so they're stuck on my camera for the time being.

(we should probably try to not derail 4mem8's thread though, so I'll post em in the robogames thread)

Remember it's a building built in the late 1800's / very early 1900's. Heavy steel everywhere, lots of ionization from the ocean constantly banging on it, literally. It's just not a great place for RF. In fact, I'm thinking it's about the least desirable place I can imagine to hold an event like that. Horrendous parking, comparatively tiny building, awful for RF, in an expensive city that is almost impossible to get around in. Consider that Silicon Valley is only 45mins away, and has some of the largest hanger buildings in the world for event rental. Infinite parking, less expensive venue and lodging. Easier access. Better roads. Fewer tourists.

I just don't get it sometimes. . .

4mem8

Adrenalynn: Ah, I now see your point, and can understand why it is difficult, it all makes sense now. Thanks for the info on that.

Adrenalynn

I have laid out the parts to look at and peruse through and get used to what they are and where they go.
Also note there are NO pico ITX parts shown here, These are being sent to me by Tyberious soon.

I am supposed to finish Wall-E first before I start this project, but the suspense is killing me
so I may have to do both at the same time.

DresnerRobotics
06-17-2008, 12:07 PM
Holy crap! I never had all the parts laying out at once since I built as I went... and to think we still have all the stuff I'm sending you to add to it. Didn't realize there were so many parts.

4mem8
06-17-2008, 01:27 PM
Ha ha, your right Tyberious,lots of pieces, However there are a coulpe of items that may not get used as I got these just in case i make any changes as I go. But looking forward to this project.

4mem8
06-18-2008, 02:28 PM
Fitted the tracks together last night, I was disapointed to find that the nylon rods were short by 9mm after you inserted the black end plugs which means that you have each track unsupported by 1 link, All you need is about 2mm clearance for this, I had thought of replacing these but my eagerness to build it out weighed it. For the cost of J5 you think they would get this right.

DresnerRobotics
06-18-2008, 02:38 PM
I never noticed that when I was building mine, but I was in a rush to get it together in my excitement.

I can tell you though, I've never noticed any structural integrity issues with the tracks, they're rock solid.

4mem8
06-18-2008, 02:59 PM
Solid they are, That's why I carried on. Nice tracks.

DresnerRobotics
06-20-2008, 03:32 PM
Yup, I did. Still tweaking with it a bit to get it right though.

BTW- We're sort of hijacking Mem's thread here, should we move some of these posts to my J5 thread? I don't mean to tread all over his territory ;)

Crap 4mem8 I wished I would have asked you to make me a silicone mold of one of the track sections, so I could make my own, but I know this is too late because you would have to replace the buttons on the ends after removing them. Oh well, I guess I'm stuck with buying the tracks and then scratch building the rest.
Great job though sofar.

To be honest, the tracks are fairly inexpensive and you'd probably be happier with just buying a set of them. I would think building them from a mold wouldnt be worth the time investment when you can purchase them relatively cheap.

4mem8
06-22-2008, 03:18 PM
Yeah, I would have to go along with that Tyberius, GW they are not that expensive to purchase as an individual unit. BUT I know you to well, and know you would like the challenge of making them.

GWJax
06-23-2008, 05:03 AM
Ya I know the tracks are only around 20 bucks but I love to make my own parts plus I have the material for it. This is just something I enjoy to do. My J5 will be all hand made for the exeception of the treads unless I can get one peice of it.

Adrenalynn
06-23-2008, 05:22 AM
Why not carve your own mold from high-res photos? Or do your own design?

GWJax
06-24-2008, 08:05 PM
I think I will make a new design. That why my J5 step child would really stand out from the rest.. Great Idea Thanks Adrenalynn!! Once I get started on the first track I'll shot a pic over to see what you all think.

4mem8
06-24-2008, 08:15 PM

4mem8 How are you going to interface the Pico ITX. I have drooled over this computer board since it was first announced, thinking of the ways I could use it, (mostly in cars). I have to be honest I never thought of it as a robot controller until now and am excited to see the implementation. With the capability of this computer so real intelegence can be inserted into a machine. Please keep us informed.
Thanks

Hi Steve,

Welcome to the Community!

Follow the link that Adrenalynn has posted to find some amazing pics,video and explanation of construction. I have made my one with slight mods also so they are not exactly the same but similar.

Thanks for the replies, Adrenalynn and 4mem8. Like I said that copmuter is an amazing platform for many things. The size and power requirements make it useful everywhere. This use in a robot is the first time I have thought of it as a controller and it excited me.
Thanks to Tyberius and everyone else on this site for a forum like this. I am one of the older folks into Tech as a hobby. I have forwarded this sites address to my 2 little nieces, (Smart girls they are), in hopes of exciting them into a hobby of electronic controllers and maybe robotics.

Apburner: I to am the older generation but this robotic game keeps me feeling very young and can't wait each day to do a litle more on it.

Here are some other mods that TYberius also suggested with my one, I had a long neck in the last post and Tyb suggested omitting the neck extension, So thought i would try it to see what it looks like, Not bad, The only difference with my version is that I can pan/tilt at a much lower angle due to the higher neck. What do you all think.??

personally i think the long neck looks better,and as you said pan/tilt angle is better.i am also toying with the idea of having his head tilt from side to side on mine,a fairly easy mode to do as well.love all the pics tho 4mem8 you can never have enough pictures!

ScuD
07-15-2008, 10:00 AM
From a purely aesthetic point of view, I think the long neck gives it more of a sympathetic kind of look, whereas the short neck makes it look more as if it has the character of an overfed chihuahua.

4mem8
07-15-2008, 05:02 PM
Thanks guys, you have confirmed my thoughts on this mod, I will put the longer neck back. Tyberius has also stated the a more 3 dimensional look might be better than the flat ASB-18 , So I had a look at this choice ASB-503 and I think would look great.
ScuD: It;s amazing how the different parts you add change the look of J5, One could very well get carried away with all the options one has, And I love it.

Getting another 6 HSR5990 servos that I bought from Tom Chang soon, so I will replace another 5 HR645's the main up/down section of the body and Base rotate and the shoulder. I want to program these servos. So just the hands and wrist HR475's and Pan/tilt are 645's the last two are an overkill but had them anyway spare. I will have quite a bit of electronics on the head eventually.

real nice work on your johnny five unit
still working on my sonar ring for one of my robots ,plus beer-bot
but going to make many changes to my johnny five as i start to build it.looking at making the base a little bigger to hold bigger batteries,and electronics and the hands to hold a beer can or bottle
may add pressure sensors
seems like johnny five needs hsr-5990 every where but pan /tilt,but i see the you need more current or less running time
keep upgrading it looks great

Robot maker: Thank you for your comments, The largest Nmhi batteries that Tyberius could find for me were 4200ma a 12v for motors, 9.6v 4200ma ITX, and I do have a [email protected] but may replace it with 7.2v 4200ma and include a 6v voltage reg for this pack so as to power the 6 analogue servos from the same pack. I agree that the base needs to be larger to accommodate all the electronics easier, as it is I may extend the rear to help in this area.

Adrenalynn: Yes I know about the D cells I have 10 12,000ma ones for other purposes, but to big for J5. 5400ma is a good size. I should get a reasonable time from 4200ma though. May look at the 5400 for the servos at a later time. Thanks for your info.

I have disassembled my J5 down to the base as I am not happy with the rotational base system, it is inadequate for the upper weight mods as the body rocks from side to side, I have drawn up a bearing system that will be rock solid using the same base but replacing the upper Disc with two 3mm Alloy discs 93mm dia, The top alloy disc will have the cut down plastic disc fitted under the top disc, The bottom disc 93mm dia is a ring with a 63mm I.D hole, This is bolted to the base. The outer edges will house the ball bearings, As the top disc is lowered on to the bearings the plastic disc under the top disc will engage the servo and the plastic disc will fit snuggly into the lower ring. This will make for a rock solid bearing. Going to the engineers shop today to price it out, At this stage will get 3 made 1 for my J5, 1 for my next Project [ You will love this rover] and a spare, I think Tyberius may be interested in the 3rd if the price is right.

i didnt know about adding links,i thought trossen adds them,good idea
also try using lazy susans,that what i might be using,i am using them on my other robots,head rotate ,arm rotate you can get the from mcmaster ,3 inch to 18 inch,round or square

Well a step backwards here on my J5, I have decided to rip it apart again as I am not satisfied with the rotation base unit and I am in the process of replacing the bearing system as it is not up to the extra modded version. So here are some pics of the disassembly.

Ok, I have pulled my J5 apart as I am not happy with a few of the designs from the stock system, so I have redesigned the upper platform to a higher level, 50mm against the stock 38mm, this allows batteries to be placed on edge and leaves room [plenty] for 5 C cells on each side of the center batteries for the 12v supply to motors in an upright position. The top plat need quite a bit of re-fabrication, but well worth the effort. Also I will be replacing the stock rotational bearing system as this was found to be rather sloppy with the added upper mods. This bearing is similar to the LBA system, It will have a 3-4mm lower alloy plate with a 93mm out dia and a 63mm inner dia and recessed for ball bearings, The upper alloy plate will be 3-4mm 93 mm dia with a central 3mm hole, The original plastic servo disc will be retained but cut down to 60mm dia and fitted to the underside of the top alloy disc, balls inserted and the two discs put together and fitted to the servo in the same manner as before. Pics so far to date.

07-19-2008, 12:16 PM
another good idea is using pan design from servocity,that my plan for my johnny five unit
the rotate base first is made cheap,cost alot and made for designs that not upgraded
you can get bearing made with brackets to fit inside small plate,plastic or metal,drawback on using plastic it that it wont hold up very long,and wont handle the weight
darwback on aluminium is adds little more weight ,and need a faster motor
i am looking into making my own servos that will be the same size but more torque and cost less then hsr-5990 and less current,made a few already for another project

I wouldn't try to tap threads into lexan generally. Not when inserts are cheap and plentiful.

I've personally put 12,000 lbs on reinforced lexan. Depends as much on engineering as on thickness, but really, what are we talking about here, 5lbs? 10lbs tops? Even medium density plastics of moderate thickness are going to hold that, and toilet paper will hold it if properly reinforced.

Robotmaker: I will be using my HSR5990 for the rotational base, in fact the only servos that are notHSR5990 will be the pan/tilt [HS 645] overkill, but have them spare. and the hands [HS475]
The motors are the stock motors that came with the kit 50:1 12v Have not tested the torque. I would also like a CNC machine, maybe one day. A lathe purchase is on the list first. soon.

yes i know,but on force on lexan is not so great i have deck of 12 inch square lexan 1/8 thick and it bends little with 7 lbs but 1/16 thick aluminium no bend even at 10 lbs
you need to reinforce lexan to get it to hold ,aluminium dont need too sometimes but for a ball bearing base it needs to be very solid or will have problems,also some times you cant reinforce lexan because it might get in the way
we use both at place where i work,inserts dont always hold up in thin lexan 1/8 and less,great for 1/2 inch maybe 1/4,best for lexan is rivets or bolts and nuts,but sometimes they get in they way unless countersink, if you check the stress test for lexan and aluminium you will find aluminuim is alot stronger for same thickness and size no reinforcement also adding reinforcement meens little more weight maybe some use standoff witch one good way to go but need screws plus standoffs,draw back is it will get in the way,just look at the base design of j5 6 standoffs makes hard to mount batteries or boards and such,not a great design ,saves money only
thats one of the changes going to overhaul on my design a better base and bigger to hold batteries and pico board

i thought you was using hsr-5990 for hand ,wrist and arm
thats good news mostly will keep hsr-5990 for hands, but will run a test on both,what i do i test for weeks every point for weekness,and i start at the hand first if it holds a bottle fine then move on,but also will test my super servo's as i call them for to see about each servo current draw ,mine i know is very low,i see on hsr-5990 very high,no wounder they need a heat sink
645mg is near mine,but depend each on the holding torque,also on each hand adding a web cam board to find the beer using my favorate program Roborealm,plus other sensors

yes that is what cnc is for making many pieces,most robots dont need many pieces unless you are many robots
but cnc is better at making precision cuts from cad programs,but at over 4 to 5 times the price
we have 3 cnc at the factory where i work ,plus 4 mills and 3 latches as a all in one machine in r&d area
sherline is one of the best,but with best comes price,so really depends if the robots we are making can justify the cost,one of my robots so far is up to $2000 and the hands still not finished or laser tracking system
i am looking to get one latter on,maybe ebay or new,but looking for short term all in one mill
right now getting ready to buy lispworks AI software,4 hour demo is too soon to have my robot off lline,best price is from my neice to get it at a reduced cost from school $700 to $800,but might buy it at full price $1000,next is more johnny five parts,mostly servo,s and main pieces

I disagree. Most robots I play with half at least half a dozen servos. That's 18 pieces, 12 identical, on a 2D CNC.

If we start getting into humanoids, a hundred identical pieces is not outside the realm of reality.

4mem8
07-23-2008, 01:45 AM
Darkback" I know where you are coming from , as there a lot of nice projects that ppl are doing here on this forum and I'de love some of them.

Adrenalynn: I am using a small band saw to cut this Lexan/Acrylic sheet, The motor speed is 1600 rpm with a tooth setting of 6 per inch, Do not use a fine blade like 10T per inch as this will clog as the Lexan/Acrylic sheet heats up. 6T works great, then sand the edge with 120grit then 180 and finally 320grit and you will get a very nice finish. Also be sure to leave the paper or plastic covering on until all cutting and holes have been drilled.

Adrenalynn

Thanks! That's great. I've been using too fine of a blade. I generally put masking tape over the cut area to prevent chipping

4mem8
07-23-2008, 02:55 AM
Yeah, the fine blade usually heats the product and the blade tends to stick to the sheet.The 6T clears the plastic without melting. Masking is good to use, I use it a lot on plastics. Speed isn't as critical as the TPI.

I've had pretty decent results using a rotozip, or dremel...I have both. They do melt the plastic, and sometimes it does crack...but when it doesn't crack, you can polish the edge with torch if your careful.

Remedy that and you'd have the full package! My construction methodology more resembles a flow chart:

Does it shift around?

If Yes - Is it supposed to shift around?

If Yes - Continue
If No - Pop rivit it and check again : Loop

When I can't get the riviter into the space, I have a large selection of adhesives... Epoxy, JB Weld, hot glue, gorilla snot, double sided tape, velcro, duct tape, electrical tape, ... I'm not bashful about employing them. ;)

Tyberius, this is how it works. When one make a master peice such as your J5 another picksup where you left off. As said by the rockets that brought man to the moon, we are now in the process in building a craft to to take man to Mars. Everything that is made can always be made better and when 4mem8 completes his J5 someone will go further than he has done, this is the only way to keep improving the J5 until he is perfect, who knows AI may be implanted in him next we'll just have to wait and see.

Front extension and rotational base. You could well be right GW, nothing is set in concrete yet, just trying it out. I may yet leave it in it's right position but just raise it 50mm instead, That way it will be in the same position but just higher to clear the rear electronics.

i noticed that on your usb blocks are going to add some weight,doing mine a little different to cut down on weight as much as i can,more weight,more torque motors,then bigger batteries or less run time,same idea using low dropout refgulators,and handheld testers we make at work that what we use alot of LDO regulators

they are not low dropout regulators
LT1083 adjustable for 7.2 volts servo's IS GOOD ONE,or LM2931 for 5 volts, low current adjustable MAX667cpa
LOW DROPOUT meens like lets take a 5 volt regulator you need near 1.25 min above 5 volts on low dropout you only need about .4 volts above,now i made a better circuit using low dropout regulator plus pass mosfet to get is down to only 5 volt needed,but need a few parts

Yes I have three fuses for, 12v, 7.2v and 9V I will be using two ubecs rated at 10amps each for ther 7.2v section as I want a stable 7.2v for my HSR5990 servos. When fully charged it reaches 8.4v to high for those servos. The ubecs come pre set for 5v, but with software and a castle link it can be changed to what ever you want.

or better yet adrenalynn great find AXON board,i might be a good salesman for AXON
i really like that board
good new about this board you dont need to use c,since it will have a plug-in to roborealm

M'mmmm That sounds like me Robot maker, I do have a Phidgets 8/8/8, Two 4 port USB's, Two 4 port servo controllers a huge range of GD2P sensors, No Max sonars or 12c to USB or Axon though, Although I should be able to use my PICO ITX M/B with roborealm and USB parts, or is the Axon better suited for the job? Also with Roborealm I take it you can access the sensors, I.R and Max sonars?.

i heard seattle robots from one of my posts he is working on a interface to roborealm in about a month
thats main reason i picked AXON BOARD,also has servo inputs,so it a good change over
so between steve and seattle robots i hope soon to they will have a fix

Update on my J5


It has been a while since my last post regarding my J5 build, As you know I have been waiting for a new Rotational base bearing, I have had 3 made, And I am in the process of fitting this now, so here are some pics of the process so far, This will be a big improvement over the existing system and should handle the load and be very stable with no slop from side to side and forward and back movements.

http://img519.imageshack.us/img519/6632/247ym9.jpg

Existing plastic servo base with inside cut to 61mm.


http://img354.imageshack.us/img354/9785/248ay4.jpg

Inside ring cut, This will be bolted to the upper Alloy ring.


http://img519.imageshack.us/img519/3067/249tv9.jpg

Lower and uppr alloy rings, these are 4mm thick and ridged, Left lower ring has been driled out for the ABS-04 Lynxmotion bracket.


http://img395.imageshack.us/img395/6713/250ke3.jpg

Plastic servo disc inserted into the upper ring for fitting. you only need about 1-2mm clearance on the sides.


http://img178.imageshack.us/img178/964/251go8.jpg

Bottom Alloy plate on top of the Lynxmotion base, This will be bolted down to the plastic base. Servo disc fitted to servo for clearance check.

http://img354.imageshack.us/img354/3702/252ta3.jpg

5 3mm Holes bored for bolting to the base unit. This bottom plate will accommodate about 100 3mm bearings.

Mouth with a difference, 3mm clear perspex has been cynoed to the edge of the LEDs top and bottom, shorter piece on the bottom, also slotted to fix under camera's. The idea of the perspex is that when the LEDs glow it will travel along the edge of the perspex creating a type of mouth in either green,yellow or red.

Perspex clearly seen here, should give an interesting effect.

The video of the base was very smooth, good to see that, as of the mouth I'm glad I sent you the tri-bot's mouth as an inspration for your J5 mouth. It turned out great 4mem8.

The LED mouth was a combination of Tyberius's design and the Tribots design, so until it's fired up I am not sure if it will do as planned, But I think it will. Particularly in the dark.Thanks GW and Tyberius.

are you having the leds left to right or right to left or both come to the center as volume increases
also looking at the real johnny five there is about 15 round leds

i watch johhny five movie again about the 10 th time and see that he has about maybe 8 leds going to the center from both the left and the right side total of 16,what main chip is used on the board you have,i used many in the past lm3915,lm3916 and lm3914 and know the chip but forgot it,even have a few at home
i may buy the board or make it,super simple circuit,for mine looking to use stereo 5 led board to get 10 leds comming in to the center,but i think one of the national lm chips also do that ,will need to check specs

Robot maker: I think I will have them going inside to out as volume increases, As this will give the illusion of a big smile when sound is louder.

As for the chip, I have always usde the LM 3915 and 14 but this is a different chip, can;t recall the number, but if you check above in my links it will take you to the site where I got my one from and it states there the chip Canakit.com.

Project for this weekend is to fabricate the eyebrows, remove the bolts from the camera's and replace with nylon ones, install two 10amp ubecs in parallel for 20 amps for the 7.2v digital servos and reduce to 6v for the analogue servos.

These ubecs can be programmed with the castle link which is plugged into your PC and programmed for the voltage you want, default is 5v.

yes i like them too,if you go to my johnny five robot club i have photos of the eyebrows design from my friend at robohut ,also asking terry from input-inc to let me post his photos for ideas and daniel b that made the nxt johnny five design also, i heard from allard the one who made the real johnny five ,that there is j5 #3 movie soon in the works
servos you are using are drawing about 20 amps peak and 14amp norm total

Is this assuming that I am using all my servos 10-5990's, 6-645's, 4-475's I may have to change the wire rating from the ubecs as I feel this is not going to be heavy enough for 20 amps.

Wires should be fine - connectors, most certainly not.

4mem8
09-23-2008, 02:58 AM
M'mmm not so sure Adrenalynn, If you look at the twin cable it is lighter than the servo wire. In should be ok but out will go to the SCC32 to be distributed amongst all those servos.And the wire from the ubec to the SCC is pretty light.

robot maker
09-23-2008, 03:06 AM
here is a idea that will work instead of using 2 bec in parallel run 1 bec to 5-5990's 2 bec to 5-5990,s and a 3rd to the rest of the servo's at 6 volts,i using a different idea for mine
and also most likely you wont run all servo's at the same time too

I could do that, Just means I have to order another one which is a pain, being in NZ freight kills the price you pay for it. I could get GWJax to send me another one [Florida] that would cut freight costs.

robot maker

i am glad i found this at castle creations web site before you smoke them

5. Can the CC BECs be run in parallel for very high current applications?
No, switching regulators like the CC BEC will fight each other if used in parallel. A separate component is needed to isolate them from each other. Castle is looking into creating something that will allow you to do this. Stay tuned

M'mmm I did not spot that one Robot maker Thanks for the find, you saved me a headache. So it looks like what you said before, one ubec for 5 5990 servos and one for the Analogue servos. +1 rep for you.

Here is a mod I had to do for the front rotational base to support it to stop flexing when the torso is moving. This has made a big difference to the stability of the upper torso.

10mm x 3mm alloy bar under the Lexan, And two alloy brackets to support the rotational base.

Hey, Robotmaker, Not tying,far from it, True I have been working on T-1, This is one of my biggest problems with my robotics, I have many on the go. I will get back to J5 soon enough though. At presen I have a big disaster on my hands, I have just forked out 5k on a new bathroom due to our floor rotting out from a faulty shower, So this is going to tie me up for about 6 weeks or so. :genmad:

RobotMaker I don't think 4mem8 is planing on running the J5 on any carpet and If he does I'm sure he eill correct this problem, most likely by putting a thin layer of plastic sheet over the screws or replacing them with flat head or round head screws. Remember this is just a work of art that may need to be moded down more.

and my johhny five is disasembled
getting the new blackfin SRV-1 near christmas from trossen,another idea latter for my johnny five if camera works great will get stereo without WIFI
in my house i have tile and carpet,so going to use flat screws,tape not so great to use,also because my design is 2 times the size it will be higher
