Let's Make Robots!

Switching Frequencies for Industrial/Automotive Solid State Relays.

I have been working on a large outdoor robot driven by "Power Wheels" children's car motors for a while now (http://boomsandbots.blogspot.ca/search/label/Project%20Killzone is the section of my blog devoted to it) and I decided to build my own high power motor controller rather than buy one. As you can imagine, it has been a journey filled with smoking electronics, learning, and rebuilding. Anyway, I have relays set up to control the direction of the motors, and that part works quite well, but the problems I have had is with the speed control section.

Which linux distro for a ETX motherboard

Hey guys, I am working on a PC robot project http://letsmakerobots.com/node/34827

anyway, I tried to install Puppy linux on a VIA nehemiah ETX board and got this error message:

This kernel requires the following features not present on the CPU:
pae cx8
Unable to boot - please use a kernel appropriate for your CPU>.

then I removed the VIA board and put a pentium board in it's place, the only thing that changed about the error message was it did not have the cx8 part.

Hello all

Posting Pictures on LMR

Hey everyone, I am new to posting on LMR, although I have been looking at the site for a while, anyway, is there a way to upload multiple picture to my projects at one time? The current system is tedious at best, and either my browser is acting up, or the upload page is not working very well, I have to hit F5 all the time to see if my pictures have loaded. Anyway, any help would be appreciated greatly.
