LMR-o-Scope

LMR on an oscilloscope.

I used Chris Meighan's ScopeShapes program to drive my oscilloscope from my PC sound card.

The program was loaded with a DXF file created by Armin Müller's eleFont program.

This was a fun day!

List of good online shops for bot parts

I was wondering where online most of you go to shop for parts? Can we construct a master list of important websites here?

This list is from the URLs I've gathered from the various tutorials:

Soldering

A while ago i was looking at some websites which helped beginners build robots. I came across two prominent sites and checked their Start here(first) robots. I found that LMR had an easier to build start here robot which i could have fun building. But there was one major problem, i could not solder. The next day i got some parts for my start here robot from Techsupplies UK and the same day, i went to a local electronics store and bought a cheap 4$ solder iron and 45gram solder with a 1$ de-soldering manual vacuum pump and a stripbard and some male header pins.

Detects objects at close range. Can be used for object tracking.
Now with video of the sensor being used as a Mintvelt inspired object tracker! This sensor is a short range obstacle detector with no dead zone. It has a reasonably … Read more

MonoCopter

Just what is the point .................. it impressed me anyways.

3 stage burnout, and what exactly is the point of the parachute............Duh

Why did i find this........... well i bought 4 rocket motors for 2 CHF (RRP 18 CHF) could not resist, dont think mine will be so effective though.

Wireless camera plus lcd screen

Ever since I have seen the land warrior system ( http://dsc.discovery.com/videos/futureweapons-land-warrior.html ) I have been thrilled and wondered how hard it would be to make a simple version for airsoft or paintball.

I just thought I would put a camera on an airsoft gun, helmet, or  something and then it would relay it to a screen preferably on a 2.5 inch screen so it is on the eye and portable. 

I would like to know if the wireless camera could keep up with the movement of someone walking for a half way decent image.

My equipment would be -

More powerful oxyhydrogen cannon

I have started to build a more powerful oxyhydrogen cannon for my second mosquito rover prototype, something similar like Estes Hydrogen Fuel Rocket:

This is my first robot. He moves with 12 servo motors. currently it has no sensors, but i intend to put them on him. He can carry a small amount of cargo in his … Read more
I just noticed that a servo and a SRF05 range finder's trigger might be able to share an output pin on Picaxe 28x1 (should work on other models too). It should be … Read more
