Hi Bigglez,
Thanks for posting the pics - nice collection!
The first O-scope I ever owned was a really old heathkit tube model and one of the things I liked about it was the smell of the hot tubes.
The clock source for the scope was the 60 Hz from the AC line - LOL.

Hi Mark, I was 13 years old too at the time of the Unicorn-1 articles and always looked forward to reading the next issue. I'd spend most of my time at the library going through the Tab robotics books too. I've got book cases full of all those old robotics and electronics books now but my favorites ...

I've uploaded a PDF (36 pages) containing most of the scanned Unicorn-1 articles to the www.scribd.com website for everyone to view or download: http://www.scribd.com/doc/3231860/Unicorn1-Robot-Articles-in-Radio-Electronics- There are a few more articles I need to scan to complete the series. Take c...

Hey Guys, I've been using the free CadSoft Eagle version for my latest project and really like it so I do want to go ahead and buy it but I'm wondering about a few things. I do eventually want to be able to use it commercially (like writing books and articles for Nuts'n'Volts) so I probably won't ge...

High Voltage Power Supply Unit Article
Hey Peter, Nice job on the High Voltage Power Supply Unit article! The printed circuit boards look really good. What software do you use and where did you get the boards made? Can anyone recommend good schematic and pcb software that doesn't cost too much ($100-$200 range)? I've been trying out the ...

I just put the exploding wire hypervelocity gun pdf up:
http://www.thinkbotics.com/exploding_wire.pdf
They were getting 4000 ft/sec from 2000 joules all the way up to
49,000 ft/sec from 3,500 joules with a lighter projectile.

Hey Guys, Ya, there are huge energy losses in the conversion of magnetic to kinetic energy with coil guns. If you dump the same amount of energy from the capacitor bank into a thin wire contained in a more traditional breech -> exploding wire -> projectile -> barrel system then you get much higher v...

Hey Peter Nice design that you came up with. I was thinking of using a PIC microcontroller to drive a transformer through something like the MC34152D. A couple of the PICs output pins could drive the device and the frequency could be programmed. One of the PICs analog to digital converters could mon...

Blame it on Rube instead
I hate when they blame the robots - LOL.
The device sounds more like a Rube Goldberg contraption...

Open source coilgun project?
Hi All,
Maybe we could get an "Open Source" type of coilgun project going based on a popular microcontroller that we all agree on?
People could submit ideas and then a few of us could breadboard and debug as we go...
