| | Re: Electro-magnets
|

IMHO is the easiest way to get strong electro-magnets to disassemble 6V relays. They include good electro-magnets. I did so and was able to hold a 500g hammer with two of them running at 6V. I used relays from FINDER (Series 55 if i remember right), (...) (24 years ago, 11-Dec-01, to lugnet.robotics)

What is your plan for the electromagnets? If you can not find them, they are simple to make yourself out of fine insulated (varnished) copper wire. You will have to do a little bit of experimenting to get the streingth just right. Wrap the wire into (...) (24 years ago, 11-Dec-01, to lugnet.robotics)

I'm sorry if this is a bit off the subject- Does anyone know where you can get small electro-magnets in the UK? Nobody seems to sell them. I am thinking of making a robot with electromagnets. BEN (24 years ago, 11-Dec-01, to lugnet.robotics)

| | source of solar panels for Lego robots?

Can anyone recommend a good source to find relatively cheap, high-power, compact solar panels that could be wired together to power an RCX, or anything else for that matter. I've seen the Lego solar panel in Lego Dacta, but it seems to be very (...) (24 years ago, 11-Dec-01, to lugnet.robotics)

Thanks again Dave. As it turns out, nqc on Mac OS X expects a firmware file with UNIX line endings. BBEdit Lite 6.1 for OS X did the job just fine. After saving with UNIX line endings, nqc was able to download the firmware. B. (...) (24 years ago, 11-Dec-01, to lugnet.robotics)

(...) NQC is picky about line endings for firmware files. On a Mac, it assumes Mac line ending, on Windows, it expects DOS endings, Unix for Unix. There are a few cross-platform combinations that work ok, but not all work. If you have BBEdit Lite, (...) (24 years ago, 11-Dec-01, to lugnet.robotics)
