Hey. First post here on the page.
This project is fairly simple but i find it useful.
I did this early December after i found an orphaned 20pin ZIF socket at work and figured i wanted to program 2313′s.
It is just a permanent Arduino ISP programmer with 3 4052 multiplexers to switch between the pinouts for the attiny85,84 and 2313.
The 4052 address pins are pulled down and set with a sp3t switch. I’ve seen shields using 3 sixway dipswitches. this seemed impractical to me.
My nano is mounted on headers and not modified in any way. I might need it for something else one day.
The leds are heartbeat/error/programming indicators
Not as pretty underneath, i used this stripboard that is cut every three holes. i find these practical when working with ic’s.
The predecessor was an old shield with ic sockets for 85 and 84.
Nest step adding a six ISP header so i can mess with ISP programming of atmega8s and other avrs by converting the arduino files to hex and programming through AVRdude
Got a request from the Brage Theater in Drammen / Norway. They wanted a weird contraption to visualize the dream of a 12 year old boy. A great invention that would change the world. They gave me a good budget and mostly free will so I ended up with this:
We should ask for some Norwegian cultural-petroleum monies and go to Burning Man this year…
Our story begins in Melanesia during World War II. Thousands of American GIs suddenly descended on this South Sea island chain, bearing with them unimaginable riches: magical foodstuffs that never spoiled, inconceivable power sources. Just as abruptly the troops departed, leaving only broken, rusted Jeeps, crumpled beer cans, and the memory of Spam. To the astonished eyes of the natives, this was a miraculous occurrence, and they yearned for the return of abundance. Accordingly, they built totemic sky-craft in an attempt to summon back these Visitors and their legendary leader, the man the Melanesians called John Frum. They had formed a Cargo Cult.
Helped out a friend doing an art class project. They are making an installation with paper tubes hanging from a roof. When you walk into the tubes a loop should start playing. Solved this with an old motion sensor from an alarm system, connected to an Arduino, connected to the PLAY button of a hacked MP3 player. The play button is connected trough an opto coupler just in case. There are some timing concerns to control the MP3-player, like giving the MP3 player time to play the loop all the way trough without new play pulses, therefore the Arduino.
The whole hack took me about three hours and was made mostly out of trash lying around my workshop.
I found this beauty on a marked in Fredrikstad on a family holiday:
I had no idea what it was but instantly fell in love! A few hours of research (AKA Googling) later i realize I have bought a pre WWII miniature Tesla Coil to stick up my ass! How cool is that!
The device is a Helio Lux Violet Ray Electro Therapy kit with a large variety of electrodes, including Eye Socked Electrodes, Anal electrode and Spinal Electrode. These devices was used for health care in the late 1930s but are now adopted by the BDSM community.
We have off course already given it a run at the 220Vs but, as expected, the device is completely dead. A look inside revealed a broken fuse and a shorted primary cap 1uF/1000V. This is now ordered from RS-components and my guess is that it’ll do the trick.
One question remains though; is the Noble Gas in the tubes still present after so many years..? Update will come when the cap arrives!
The Chess Sequencer is a step matrix sequencer made from a chess board, where placing the pieces make music. The sequencer is connected to software synths on my Mac trough USB and a Processing patch to convert the serial data to internal midi.
