The site is getting worked on again.
However, since i like to move fast and break things I am bypassing QA right now and, as long as my content is there, letting things happen. So formatting may look weird here and there but unless a link is actually broken, or content missing, please do not bother telling me as I likely know (and am in the middle of fiddling with it).
Cheers,

There is now a Git repo for people to submit tips, tricks, and advice to! Why a Git repo you ask rather than a wiki? It allows people to pull in an offline copy quickly and easily.

I wanted to install the option of an alternate Microphone for a Yaesu mobile radio which uses a modular (RJ11) type hand mic, whilst keeping the original microphone DTMF Functions.
I made this modification because I want to use the Headset from my Hand Held Transceiver, a Pryme SPM-1500 Throat Microphone, with my mobile unit for a hands free operation. This would also block out noice form my car stereo, or noise from other influences like a rolled down window.

This project was a simple Hard Drive Window. Originally was going to be used for another project involving lasers, mirrors, and the moving platter/drive head. However, I could never find enough drives with similar head mechanics for that project to see the light of day.

I built a capacitor pulse bank a while back. It was installed into a large suitcase, and was using Electrolytic capacitors (so no super-fast rise times, but a fairly decent amount of energy density for the cost).
Caps: 6x caps rated 5600uF @ 500V ==> E =(1/2)*C*(V^2) = 4.2 kiloJoules of energy.
The Pulse Bank was designed to fit into a Pelican 1600 case for durability and ease of transit. The case included a wired remote control, the capacitors, and a triggered spark gap. It was fairly simplistic in design, but useful for a time. While most of my project videos and files were lost in a set of failures long ago (who would have expected an entire RAID 6 and backup system to go within the same week), these photos are here at least as what was recoverable.
This project is a favorite of mine, and the one shown here was built for the “laboratory of the Scientists from Krypton that saved Superman from the exploding planet room thingy” of a past event.
The Jacob’s Ladder is a pair of vertical (or in extreme cases, horizontal) electrodes that are parallel to each other and connected to a source of High Voltage. The air between the bottom of the electrodes has a Dielectric Breakdown due to the high voltage potential and creates an Electrical Arc.

I have been interested in the quirky sides of electronics for as long as I can remember, but I don’t know how Nixies evaded my eye for so long. Only during my first semester of college did I come across them. Such an awesome looking display, the 3D look to it and the glow of a tube-like device. Like many before me, I instantly decided that I needed to make a clock.
I built a PVC cannon fueled by Acetylene gas back in high school (this is part of my old project archives migrating here). The gas was generated by Calcium Carbide. This cannon originally had electronic ignition but after several fires the igniter decided to “remove” itself from the cannon. This cannon also has an expansion chamber to get a better fuel/air ratio for larger amounts of fuel.
This is primarily a SALUTE cannon, not a launcher. While it can launch things, I made it to make a very loud noise for things like 4th of July or special occasions.
The first revision of DEFCON for Noobs is up. Still very rough, early draft, and missing many things. However, I figured a living document is better and would do better with feedback.

Over the years I have acquired many tools and tricks used to gain entry to a target office. At DEFCON 23 I got a lot of questions regarding my custom pack, and the gear inside.
While I cannot share every detail (that would give away too many trade secrets), I have dissected the general pack here for your perusal.
