Radioactive trip

IMG_6983I went for a radioactive hunt with my friend. Some time ago we heard a rumor, that in Paukkajanvaara there was small uranium mine and enrichment facility between 1958 and 1961. Amount of mined uranium was small, and after 60s reduced need for uranium, mine was closed and never re-opened. During closing no cleanup was made, and due 60s lower standards and general neglect whole mining site was contaminated with radioactive uranium products.

We packed our cameras and a geiger counter and started car at this cloudy sunday afternoon. 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).

First post, opened the new blog!

Hello world! This is my first post to this WordPress- based blog. My original blog is terrible, coding sucks, layout is from the 90’s, and I started writing in Finnish, and never got around to translating the articles. So now I’m starting from a clean slate. Maybe this time I will get it right. Only time will tell.

Coming soon: I will try to make a dedicated page for my nixie clock, and maybe translate some old interesting articles from the old blog.
