And no LEDs either. Looked like just the motor and battery. That's what i call keeping it simple. That's the way, aha aha I like it, Fri, 20 Nov 2009 14:25:07 GMT jabmechtech http://tech.groups.yahoo.com/group/beam/message/59748 http://tech.groups.yahoo.com/group/beam/message/59748 YEP,, I saw them at ToyR us and they even have a track of sorts ,, mini inviroment for them to play in.. as far as I can tell, they are , just that, a britle Fri, 20 Nov 2009 04:59:22 GMT jonjb2a http://tech.groups.yahoo.com/group/beam/message/59747 http://tech.groups.yahoo.com/group/beam/message/59747 Has anyone seen Hexbug Nano's(TM????). I've seen them carried at the local radio shack and sort of broke down and bought two! So much for ten bux apiece.

By just over a week. Blame me, blame me... to darn busy getting ready for a trip to realize how quick things were happening.

Thanks. Sat, 07 Nov 2009 10:35:26 GMT jodicalhon http://tech.groups.yahoo.com/group/beam/message/59741 http://tech.groups.yahoo.com/group/beam/message/59741 What circuit are you working from? From memory, you should have a 1kohm resistor and an LED in series across the power rails. +ve rail -> 1kohm -> ordinary LED Sat, 07 Nov 2009 04:31:19 GMT jonjb2a http://tech.groups.yahoo.com/group/beam/message/59740 http://tech.groups.yahoo.com/group/beam/message/59740 I am not too certain about the instructions for wiring in "Herbie the photovore's" eyes. Do I solder the negative leads to Pin 6 on the LM386 and positive Sat, 07 Nov 2009 04:23:32 GMT jonjb2a http://tech.groups.yahoo.com/group/beam/message/59739 http://tech.groups.yahoo.com/group/beam/message/59739 Thanks.

I had to order new heads for it, but Wed, 04 Nov 2009 17:59:23 GMT Steve http://tech.groups.yahoo.com/group/beam/message/59737 http://tech.groups.yahoo.com/group/beam/message/59737 Hello all, are your robots looking for some time out to play? The Canadian National Robot Games are coming soon November 21, 22 at the Ontario Science Center. Tue, 03 Nov 2009 16:38:31 GMT jonjb2a http://tech.groups.yahoo.com/group/beam/message/59736 http://tech.groups.yahoo.com/group/beam/message/59736 GThanks. Probably time to upgrade soldering iron since it's showing signs of wear and tear, big time. Btw: a spot welder? That's something interesting to Tue, 03 Nov 2009 16:29:45 GMT jonjb2a http://tech.groups.yahoo.com/group/beam/message/59735 http://tech.groups.yahoo.com/group/beam/message/59735 Direct sunlight, IR, UV, microwaves, X-rays, gamma rays: all have their potential hazards. thanks for the warning.
