Info About Propeller Proto Board USB

Parallax used to sell a USB version of their Propeller Proto Board.

I had a few extra of the USB Propeller Proto Boards which I gave to a couple of LMRians. I wanted to explain some of the quirks these boards have. I thought other LMRian might also find the information useful.

XMOS Challenge : ONR robot beginnings

Description of the ONR (maybe a real name TBA)

This robot is to navigate outdoors from point to point, possibly going through a series of predetermined points. Point location can be marked by traffic cones, GPS coordinates, or other orienteering markers as detailed in various contests like Robomagellan or the DPRG outdoor contests.  Requirements include finding and recognizing the point, as well as negotiating any obstacles between points, and maintaining a remote stop.

Hacked tyco rebound rc car, now I need ideas on what to do with it

Today I dug out one of my old childhood favorites, the tyco rebound. In case you've never seen one, the rebound has 4 wheels large enough so the car can flip itself over. Steering is done like a tank with no treads, each side going forward or backward. It's also FAST. I tore it open and it's built perfectly for modding. There are 6 wires attached to a circuit board. 2 for each motor and two coming from a 6 volt battery pack.

LPC1114 USB-Serial Solution -- Rerolling Boot Uploader

UPDATE: 6/04/14

Working UUE, but I know there are better ways to write it.  And I still need to deal with null padding.

Need help "translating" a C program to work in Arduino

I need an expert in C/C++ programming to help me translate a fairly complex piece of C code into Arduino specific code, perhaps even create a library. The original author of the code can't do it, but we have his permission to do it, as the code is released for hobby use only.

 The code is very interesting for many Arduino based robots, lots of people will benefit if we can make it work.

Please reply here or PM me if you're interested. Thanks. 

A question about hooking up 2 LDRs to 1 picaxe input.

Hey everybody. I am a long time lurker on this site and I would like to thank you all for all the valuable information here. I have built a start here bot and a few more complex things of my own. Now I am trying to build a very small sized robot with a picaxe 08m.

I am a beginner in electronics. I know how to hook up a LDR and read the input, but I would like to know if there is a possibilty to hook up 2 to 1 input. The problem is I am short 1 input on my robot and all the other picaxe pins are in use. The 2 ldrs would be used as left and right eyes in a sense.
