    Smile Starting smaller

    Dear Community:

    I am putting my big project on hold until I get some smaller projects under my belt.

    So for my first one I am planning is two servo, one motor rover using an arduino controller. One servo is gong to be used for steering the drive motor and the other for sonar and other sensors platform. It will be about lunchbox sized.

    The question I have is how to drive the motor. I have a motor from a cordless screwdriver that was powered by a three cell ("C" size) pack. I am assuming 3.6 volts. Unfortunately, there is no other data.

    Later there will be a question on sensors

    Yours,

    Motor controller. But we need to know something about the motor

    If it's a 3S lithium, don't assume 3.6v. A 3S lithium would be 11.1v

    3 cell NiMH is probably 3.6v

    What did the charger put out?

    If you put a multimeter across the fully charged pack, what does the multimeter read?

    Dear Community:

    I am back. Sorry for the delay in responding, life happen. One of the life happenings is that I am back to school taking computers and electronics. Basically, getting a degree in what I already know. So far I just been updating my terminology and dusting off old braincells.

    One of my classes is Intro to C Programing. The last time I did programing was in basic and ladder logic. // please #include <"line.#>" :REM Wow you can program without line numbers?! Boy do I feel like a 80386.

    Back to the rover, the current plan is use two stepper motors and a single DC motor. I will be using the DC motor for the drive (found a better one than the cordless one), one stepper for steering, and the other one for senor direction. This is starting to look like a collage project.

    Updates will slow, but coming.

    Yours,

    It could be written when you go on the UPS site and track your order. I've also noticed that sometimes they take away the ETA (I guess a storm or something like that).

    Dear Community:

    Interesting, UPS ground is faster than UPS 3-day? Or is Trossen so good and they use a single charged flux capacitor in their packaging?

    Ground is unguaranteed. 3 day, 2 day, overnight, priority overnight, etc. are guaranteed. If they don't get there on time you can open a complaint ticket with UPS and they'll ignore it in the order they receive it. Just one of the many services they offer [to mess up].
