Yesterday I found an old calculator from e-waste center, which caught my attention. At first glance I knew that this was not ordinary VFD or LED display desktop calculator. So I stuffed it into my bag and scurried back to home with my precious find. At home I plugged the calculator into the wall socket, which I probably shouldn’t have done. Of course it did not work. But no worries, what could I could not fix? Read More …

Why u no work >:C
So the Nixie-clock isn’t working,.I don’t know why, but the AVR hangs when an I2C routine starts. RTC and I/O extender ic’s should be alright, because they are brand new from ESD tube. And yes, the pull-up resistors are also connected rightly and are 4,7k, which worked on the breadboard perfectly. I’m out of ideas how to make it work. My last resort is to try new AVR when it comes from ebay. If it will not work then, I don’t want to continue whole project <.<
Also, my 8800GT GPU card died today. 
Yes, something went horribly wrong and now it crashes every 5 minutes. Last spring I did reflow soldering because memory IC’s were detached from PCB. Maybe it’s now time to say good bye to an old friend and let it rest in peace. I will buy used 4850 for 50€ so wish me luck!
There’s something good, I found a broken and wet TravelMate 7520G 17″ laptop from the garbage one rainy day. It had broken LCD inverter cable which was an easy fix, and some coke on keyboard. I dried it, washed mobo with G20 dry cleaner (amazing stuff), changed the bios battery and it started to work \o/. Some days later i found another ACER 17″ with broken integrated GPU, which had same keyboard, so now I have a working high performance laptop (yeah I know, over 5 years old amd X2 64 TL-58, HD2400XT, 2GB PC2-6400 and 2x 160GiB WD blues is not even near high performance by todays standard(I could probably get faster netbook or tablet), but more than enough for me).
