Since my printer's "acting up," I pulled up my .pdf file that I'd emailed a friend. The original Word doc is in limbo on my old MacBook. Therefore, I looked at the digital copy on my iPad Pro, typed a new doc on my new MacBook, & took a pic with my iPhone 6+.
I re-typed the document & changed some items to fit the upcoming riverboat cruise. And yes, I am in the picture. The iPad Pro & MacBook are laying on my legs. My leg is there.
I got this board because I needed a development platform for one of my microcontrollers. At the same time, I ordered an Atmel AVR ISP MkII programmer, which I wanted to use because it is a native USB device and is a little easier to use on the Mac. Of course, it turns out that the programmer has a different type of ISP connector than this board was expecting.
So, this is a Olimex development board for Atmel AVR 20-pin microcontrollers, modified it to accept input from the AVR ISP MkII, which has a six-pin output connector. The header that I added is at the bottom of the board.

Replaced every button, cleaned all the bug yuck out from the inside, replaced the keyboard, cleaned every slider, cleaned every slider and button/knob cap, and cleaned and degreased the top panel.
La Contaflex Super seconda serie prodotta dalla Zeiss Ikon tra il 1962 ed il 1965 é caratterizzata dalla forma piú moderna della calotta rispetto alla precedente versione, dalla mancanza della caratteristica rotellina frontale per la regolazione dei diaframmi, dall'adozione del piú moderno otturatore Synchro-Compur-X e dalle dimensioni allungate del corpo per poter utilizzare il magazzino intercambiabile della Contarex, al contempo l'obiettivo Tessar fu ridisegnato per ottenere migliori prestazioni e come tradizione non era una macchina alla portata di tutti, costando circa il doppio di una reflex Canon. Questa Contaflex é l'unica della serie ad avere le ghiere dei tempi e dei diaframmi completamente indipendenti permettendo cosà una completa libertá di scelta delle impostazioni.Infatti il modello precedente aveva la ghiera dei diaframmi vincolata a quella della sensibilitá é ció impediva l'impostazioni di alcuni diaframmi al di fuori di quelli consentiti, mentre i modello susseguenti avranno il blocco della ghiera automatico per l'impostazione a prioritá di diaframmi. Essa é tutt'oggi una delle piú affascinanti fotocamere di produzione tedesca, e possederne una da senso al motto "Deutsche Wertarbeit", ovvero "un prodotto di alta qualità tedesca" che doveva essere conosciuto, e riconosciuto, in tutto il mondo. Malgrado l'elevato prezzo essa veniva venduta in perdita dalla Zeiss ma era il cavallo trainante di tutta la produzione.Dotata di esposimetro esterno al selenio con indicatore sulla calotta e nel mirino, la Super fu secondo la pubblicitá dell'epoca la piú venduta reflex di tutti i tempi.
Purtroppo la Contaflex fu il canto del cigno dell'industria fotografica tedesca, di li a poco sommersa dalla marea giapponese. La Contaflex é un'oggetto superbo da tenere in vetrina o da portare in giro ed usare orgogliosamente mostrando una perizia fotografica d'altri tempi, altro che giocattolini digitali!
it's tetris, in an altoids tin!
inside is an Arduino chip on a custom pcb that connects it to this LCD ($1 from sparkfun, talks over SPI) and four buttons. rotation works properly, collision detection seems to work fine, etc.
the eagle files are on randomskk.net/projects/arduino_tetris while the code is on github.com/randomskk/arduino_tetris (note that it's designed to be compiled from a makefile but you can strip out the WProgram and main() function at the end to make it compile from the arduino IDE)
I made it for a friend's birthday present and he seems to really like it
Innards of an old piece of electronic gear, part of that same stash of electronics in an old factory.
There was no bird crap on this, probably because it was on a middle shelf, but the lone feather made its way onto the tubes anyway.

This is an EMI BTR-2 used in recording studios and broadcast, most famously used in the BBC and EMI's Abbey road studios from 1952 onwards. The recorder consists of large valve powered modules located inside the recorder, a modular tape deck and modular front panel interconnected by a large wireing loom. The BBC kept on useing these machines well into the 80's but modified the electronics to transistor stereo which sadly had its drawbacks.
I am always looking to purchase these machines if anyone knows of one for sale :-)
a special thank you to flikr member Fixerbob for donating this wonderful machine.
This PCB contains most of the inner workings of the Inspiron 11z laptop: CPU, chipset, memory slot. Same daughter card may be utilized on other Dell laptop models as well, providing an easy way to repackaging the same hardware in different enclosures.
It appears that the VRM for the processor is located on this card as well.
So after a lot of experimentation here is the setup I have settled on for the portal turret. The breadboards are only for the prototype stage and won't be part of the final setup. The turret has a small motion sensor in the lower part of the picture that is connect to the arduino. Every time motion is detected the setup randomly plays one of 17 audio clips through the sound board(the red one). The sound module in turn is connected to a small speaker that has surprisingly good sound quality for 4 dollars. I really wanted to make sure tracks were not repeated too frequently so the system randomly shuffles the 17 tracks and then plays 1 track each time motion is detected. After all 17 tracks are played, the system reshuffles the list again. As an added bonus there will be a small button on the turret that when pressed will play the portal theme song. The system will have the ability to be powered by either the internal battery source or with the flip of a button, be plugged into the wall with an adapter so it can be left on without worry of constantly needing to change batteries. The only other piece not featured which I will post images of soon is the eyeball. The 4 LEDs on the left are part of the eye and glow bright red.

Back in the mid-1960s my dad acquired a secondhand reel-to-reel tape recorder and for a few years we used it to record ourselves talking, reciting poetry & singing. I also used it later on for making recordings of the Top 40 charts from the radio.
Many years later, after the tape machine itself had disappeared, I bought a new Akai reel-to-reel recorder and when I found the old tapes from the 1960s I made a compilation for my mum on cassette tape, which is the tape in the above photo.
A few weeks ago I borrowed the tape from my mum so that I could bring things up to date & make a digital version which I could then burn onto Audio CD. Firstly I transferred the tape to MiniDisc, optimising the levels & doing minor editing & creating track marks. Then I transferred the MD version to CD using the Tascam CD-RW700.

Fans of Futurama will get this. If your not a fan of Futurama then you'll just think I'm weird. Either way, I'm ok with it.
Anyway, I was watching the new season of Futurama this evening and I remembered how Bender the robot gets all excited when he sees circuits and wiring. So I grabbed an old hard disk drive from my office and took a macro shot. I focused on the 101 transistor in the centre just to add some extra Robotty feeling to the shot.
Strobist info :- SB900 with LumiQuest Softbox III at 1/64 and triggered using Nikons CLS.
Shot details :- ISO 200, 35mm (20mm extension tube), 0 ev, f/2, 1/60
A simple counting machine I designed and built for my son. Select the value with the dial in the middle, then push the green button to add it to the total or the red button to subtract it. The case is laser cut from bamboo.

I've made this small box that sits in my locker at the local maker-/hackerspace and lets me quickly setup for some electronics work. I'm in the process of building a small adjustable power supply to fit under the drawers. And also see if I can find a soldering iron to fit in there.
The boxes on top are not stored there but the workbench was designed for the them to fit on top. When closed the space up there stores a powerstrip and the lamp. (more info here: nisker.net/projects/mini-electronics-toolstorage-box/)
I've got a large version of this as my home electronics workbench at home : nisker.net/projects/mew
At long last, after way too much procrastination, I have finished setting up my home electronics workbench. I used to work on a tiny folding table in the middle of the room with about two feet by two feet of empty space, and my parts cabinets on the floor on the other side of the room. This is much better.
