currently have the leds working and being controlled by puredata (http://puredata.info/). Only one of the leds is wired incorrectly, but I think it should be easy enough to resolder (knock on wood).
Something is going wrong in my switch parallel to serial conversion though, need to debug.
I was all excited to get tinkering but couldn't locate my breadboard, which was last seen when I was in college, so with my fingers crossed I headed to Radio Shack. I was pretty sure they would be useless, but not only did they have a selection of breadboards, but also they also had Arduinos in stock. I am amazed.
A Dremel and a polishing wheel took care of the paint or enamel that was baked-on to the tip sleeve. I've cleaned up the other parts as good as possible, and bought a 700F tip at the local electronics store.
A campuswide electronics recycling drive on April 20 and 22 allowed people to drop off old computers, phones, printers and even typewriters. Staffers from University Information Services wiped personal data from the electronics before sending them out for recycling.

This close-up shows the name Stark-Knudsen clearly on the meter face. I'm not sure what the relationship was or if Knudsen was a partner of Milton Stark's.
You can see here, the table is spinning at 33 1/3 RPM as the largest dots appear stationary under the strobe.

Electron Memories is an idea that represents my Jewelry and accessories made ​​from recycled electronic components. Memories Electron was born by combining my passion for technology, art and the need to live in a less polluted world. I started taking apart old electronics components that are no longer used or thrown in the street that pollute the soil and underground water.
Researched and dabbled on current trends in jewelry and accessories, it began to emerge creatures and objects of art. So, recycling and combining these old electronics devices where electrons circulates before are now only memories of his travels at the speed of light, these gems were born.
Electron Memories es la idea que representa a mis Joyas y accesorios hechos con componentes electrónicos reciclados. Electron Memories nació combinando la pasión por la tecnologÃa, el arte y la necesidad de vivir en un mundo menos contaminado. Comencé desarmando viejos aparatos electrónicos que ya no usaba o que encontraba en la calle e iban a contaminar la tierra y el agua enterrados como relleno. Reconecté mi pasado artÃstico de maquetista y se despertó nuevamente el artista que estaba hibernando hasta esta primavera de colores y formas caracterÃsticos de los variopintos componentes electrónicos.
Investigué e incursioné sobre las tendencias actuales en joyas y accesorios y empezaron a surgir criaturas y objetos de arte.
Asà reciclando, combinando y resignificando estos antiguos artilugios de la electrónica por donde antes circulaban electrones y hoy sólo quedan los recuerdos de sus viajes a la velocidad de la luz, nacieron estas joyas. Hernan Bressan.​

Rocket electronics. The open shaped thing on the top is a primitive kind of launch detection mechanism. When the rocket is launched the block inside will rotate over the axis and stay locked in top position, thereby starting an egg timer which will execute the separation and recovery mechanisms.
so, japan has this law that will ban resale of used/vintage electronics (PSE law) and it is sort of about to take place starting April 06. The diet is now considering about doing some amends to the law, but anyway, people are pissed. This would mean no vintage music electronics, no old game consoles, etc. How fucked up is that?
Anyway, some interesting sites to visit:

Inside of some of the modules... just quite regular looking electronics, with imported and locally made componants.
Just the SMT transistors to add on the back. Hand soldering the TQFP AVR microcontroller was interesting.
PCB through the excellent DorkbotPDX batch PCB service (nice colour)!

I just love that sparkly background liquid-crystal displays have! A camera flash brings it right out, too.
I've long wanted to learn how to use graphic LCD modules. They're fairly cheap liquid-crystal displays designed to be used in a variety of devices, and it's very likely you've seen some of them just like this one used in equipment around town. For you other Salt Lakers out there, I'm pretty sure the gas pumps at the Costco on 3rd West and about 17th South use displays like the one pictured here.
Your laptop screen or desktop flat-panel is the great-great-great-etc. grandchild of the generation of displays this one belongs to. The heart of this one is a chip called the Toshiba T6963C and I think it was designed in the 1980s. Though this individual display was built in about 1998, it has a very 1980s feel to it - very slow drawing and capable only of black and white. T6963C-based displays can show some simple clunky pictures - I think you're required to make them display Tux the Linux Penguin at least once or they take away your geek ID card.
For me, these displays were demystified by the T6963C Rosetta Stone by Steve Lawther. Mr. Lawther, a helpful British guy - sorry, bloke, designed a straightforward test circuit for these displays around ten years ago. I get the sense that many if not most electronics hobbyists who have used displays based on the chip have started from his design. The test circuit is based on an obsolete MCU, so I ported his code for a newer chip and (as they say across the pond) Bob's your uncle.
His test code didn't include a checkerboard screen like this - that was my own contribution, because I like checkerboards.
I'm not sure what I want to use these displays for just yet, but I dig knowing that I can in fact get them to work.

Consumer radio receiver made in USSR. It begins to become a rare item, and the prices are rising up onto the collector market.

My first PCB: a breakout board for ERNI's MagJack.
I had to design my own part for this as I couldn't find a library for the jack. Once you get the hang of it, it's not that tricky. Once that and the design part were taken care of, the rest was pretty smooth. I used paper of a recruiting handout from a university to print the toner transfers. It worked out pretty well (I did have to make a few corrections – sharpie, exacto). I wasn't sure what to use for drilling, so I used a small conical shaped diamond bit with a Dremel. It too, worked out pretty well. I have to say I'm really happy of the end result and will not hesitate to do it again.
