-- 1965 -- EXA w/50mm f2.9 Ludwig Meritar -- cost: $33.95. -- but here the body is shown with the once coveted (Zeiss) Jena Flektagon Macro 35mm f2.8, focussing down to about two inches. I'm 61 and purchased this when I was 16. The Dresden made Exas were bricks and many still persist in taking terrific photos. Photo take with Canon 20D with Canon L 17-40mm f4, w/ inboard flash.
Alternative to other CSC offerings, this capable camera made by the most evolving electronics company is a interesting offering now, when the NX300 is here. Large APS-C sensor with usable ISO 3200, easy handling, very solid build, many functions for both amateur and advanced photographers, full controls, WiFi connectivity, 8 fps, and very good lenses. The 18-55 is really nice, and firmware modifications made the auto focus faster and raw files smaller. Now when the production life of the NX210 comes to an end, some local resellers run crazy and the price is falling like a stone - I found this one for $250 with some benefits. For that money it´s a quite powerful and handy camera.
This series of images of the Panasonic Lumix DMC-GF1 fitted to Legacy Lenses was shot with a Canon S90 compact camera.
Here we see the GF1 clinging to a NIKKOR 85mm 1:1.4 AI-s using a Voigtlӓnder MFT/LEM F adapter.
Wrapped around this cardiac balloon catheter are temperature and EKG sensors and LEDs. The wires are stretchable coils.
It is manufactured with a lift-off MEMS process. The etched silicon is then stretched and attached to a polymer backing. Silicon usage is minimized over the substrate and the ensemble is quite flexible, to survive inflation and deflation of the balloon.
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.
Read more about getting started programming the AVR on the Mac here.

I bought a Macbook Pro 13" (Used - but new) for £330 and the RRP is £800 new on amazon at the moment, that's a great bargain!
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
Bits and bobs
Pictures taken during exercising my hobby (electronics) and building/disassembling amplifiers and/or upgrading a record player tonearm and pre-amplifier. Anyway, a text was needed, to describe this lot, and here it is (the text and the lot, enjoy the pictures :)).
Just a pic I am using to try to sell my 80-200 on craigslist it is not getting much use these day and it needs a good home. If anyone is interested just pm me.

glitchNES is an open source software project for the Nintendo Entertainment System. This software causes graphical glitches similar to hardware circuit-bending. The current version is 0.1 (initial release).
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.

This is one of my recent bargains from the used bin of a local camera store. The original mount is for Contax / Yashica, and I am using a DVD Technik adapter from a fellow FMer that converts it to an EF mount.
The image quality is outstanding, easily beating my plasic EF 50/1.8 II which cost more(!) than this all-metal beautiy. Image samples
As this is a fully manual lens, stopped down metering is necessary for exposure control on a modern DSLR. However, it's not much of a problem if you shoot in Av mode. Manual focus is a bit hit or miss with the small viewfinder of my XT, but there are 3rd party split prism focussing screens available which I am currently considering.
