X-Ray of a graphics card
I took an X-Ray and photos of the front and back of a GeForce 6800 GT graphics card.
A photo of the front of the graphics card in comparison with an X-Ray of the same spot.
I modified my Olympus Pen E-PL1 to take Infrared pictures.
A little info on what this means and some example pictures
Comparison of an Infrared picture vs. a RGB picture on the basis of a phtograph of Vienna by night. Pay attention to the fog in the distance. (Drag the vertical bar to compare the photos)

Old electric contactor from an elevator
A few years ago the elevator in my apartment building was replaced. The changed the motor, the controls and the cabin.
I could not resist and salvaged some parts of the control. Among other parts I saved the electric contactor switching the motor. Here are some Pictures. Continue reading Old electric contactor from an elevator

Some old but interesting circuit boards from HP
I found a crate with old Hewlett Packard PCB in the storage. It’s sad enough that they sit in storage so I thought I share some pictures of them. I think it’s interesting to see how they where designed back in the day. Continue reading Some old but interesting circuit boards from HP
Low-temperature cooker/Sous-vide controller

I bought a temperature controller and a temperature probe from DealExtreme to control the temperature of a water filled pot.
After using the controller for some time only with floating wiring I decided that it was time to mounted it into a proper case (As for myself an absolutely unsafe wooden box with mains voltage inside is okay). The pictures don’t need much description. The BOM is at the bottom of this page.
This setup can be used to cook meat, make nice breakfast eggs, soften wax (used when modelmaking things with wax) and (very important) cook perfect Weisswürste!

High voltage generator from ebay
I bought this “DC 3.6v-6v to 400kV Boost Step-up Pulse Power Module High-voltage Generator” thingy from on ebay thinking it’s total crap since the description is nonsense. Stating it can deliver 200kV and also stating it can deliver 400-600kV but no even mentioning the polarity of the input. It was only $3.95 (including shipping) so I bought it anyway.
Of course it can’t generate Voltages nowhere near to 600kV or even 200kV but HELLO! It puts out enough voltage for some nice sparks. I’m still looking for a volunteer to test the how these sparks feel :D
