I Just joined the group and read your posting. It depends what do you want to use your cad for. Blender and Rhino are great but not it you want to machine...
Hey, welcome! Thanks for the reply. For my purposes I was seeking a CAD for aiding in more accurate representations of my projects' mechanical end(s). I...
Hi All, I'm fairly new to Microcontroller programming and to electronics in general. Recently my first project (beside blinking LEDs) was to build and RPM...
Hello Everyone, Science World accidentally sent me the club's honorarium for the June 2,3 robotics show. Do you have an account for cashing the cheque? I...
Hi James, ... You should measure approx whatever your supply voltage is. The author of the instructable seems to be using a 3-cell battery pack, which is where...
It's quite likely that your AVR's outputs simply can't handle the amount of current that the motor naturally draws. The motor coils have a DC resistance of...
Ah, I read further on the web page. He says his motor is 125 ohms per winding. Connected to 5 V directly, it would draw only 40 mA. The microprocessor...
Even so, you would want to use a current driver or some kind of isolation between your microcontroller and motor. Inductive load spikes have to be buffered. ...
its not hard to make up drivers for stepper motors, especially if their not bipolar (just 4 wires comming out of them) If your removing the stepper from a...

Thanks for explaining this. Now I understand what's going on. I didn't realize that my motor draws almost 10 times more current. On the bright side if I hook...
Hi James, ... I expect to be placing a DigiKey order sometime in the next week (i.e. no later than next weekend), so you're welcome to piggyback on my order....
