Looking for an accelerometer

I am in the market for an accelerometer and figured I'd ask the LMR forum before I ran out an bought one. I have tons of goodies to swap; iDuino, Vex pneumatics, omni wheels, etc.

Any takers?

Building Circuit Diagram Software

I have seen quite a few folks on here replying to others with circuit diagrams. My question is what software does everyone use/prefer? I know some use Photoshop or Illustrator. Anything else anyone would reccomend?

 

Advice - PICAXE to PICAXE IR

Guys-

The goal is to allow 2 PICAXE chips to speak with each other via IR.

What receiver and transmitter have you all had success with. Where can I purchase? (links?)

Thanks all.

PICAXE and LCD

I have looked over CtCs post regarding similar issues with his LCD, but still can get mine to budge. I was hoping to get some guidance on my issue. The issue being I can't get the LCD to work or interface with my PICAXE. Like Ctc, I am using the serial backpack from SparkFun. Here is my code:

Sharp IR Sensor with PICAXE-40x1 Oddity

I am using both a PICAXE-40x1 and a Sharp IR proximity sensor.

My issue is: when I download my code to the PICAXE chip the program editor throws an error saying "cable unplugged, floating pin, etc." When I pull the ground wire on the sensor, the code will download. Clearly an issue with the sensor or how I have it wired. Per the sensor schematic, I have power, ground and signla all wired in.

Has anyone run into anything similar?

Thanks.

PICAXE C?

Someone once mentioned it is possible to program a PICAXE in C. Is this true? Anyone have any experience with this? This seems odd since I thought all a PICAXE was is a PIC with a BASIC interpreter.

Just curious...

Suggest me a motor controller

I am researching motor controllers and am looking to try something new. Previously I have used the Dimension Engineering Sabertooth 2x5 and am looking for something in the same ballpark.

The controller will interface with a PICAXE 40x. So please feel free to shoot me some suggestions.

Thanks,

David
