Few words about me:From very childhood I loved computers, electronics, lasers, sulfuric acid and liquid nitrogen. I always wanted to be making microchips, UAVs and see nuclear explosion.
Now I am doing software engineering and in the spare time - some microelectronics and physics/chemistry experiments.
I live and work in Russia, Moscow.

ARM Cortex M3-based microcontrollers, flash memory, rad-hard microcontroller.
Checked further 50 metro ticketsToday I've "opened" further 50 Moscow metro tickets. I was looking for RFID chips made by Sitronics-Mikron.
Unfortunately, no luck yet, all chips made by NXP. Total number of tickets checked - 90.
Update: Finished 19 remaining ones, now 109 total.
Update: +13, 122 total.
Update: 11'th January 2013 +10, 132 total.
Update: 20'th January 2013 +15, 147 total.
Update: 2'nd of February 2013 +1, new package design, 148 total.
Update: 8'th of February 2013 +18, 166 total. 6 of these were designed and manufactured by Mikron - finally a success! Here are there photos.
Milky way 108199*81503 gigaphoto or 65500*65500 should be enough for anybodyFew days ago there was a piece of news, that ESO’s Paranal Observatory released most detailed photo of the core of our galaxy made by VISTA telescope in infrared spectrum with resolution 108199x81503.
Unfortunately, they only released it as online zoomable image and 24Gb .psb-file, which you can only open with Photoshop. Photoshop itself can only export it into psb, tiff (unsucesfully, due to 2/4Gb file limit) or RAW formats. And I wanted something which would allow me to cut few pieces for wallpaper...
First of all, here are the results:
1920x1200 2560x1600 2880x1800
Luminol ChemiluminescenceAs Luminol works poorly in water, I had to use Dimethyl sulfoxide as a solvent (150ml). Other ingredients are KOH (~10g) and Hydroperitum (3g). No catalysts were used. ~0.5g of Luminol. One should not use usual hydrogen peroxide, unless you are ready to clean your ceiling (also, whole idea of using DMSO was to avoid water).
This photo is ~30 hours after reaction started.
TL866CS MiniPro programmerJust received USB EEPROM programmer TL866CS MiniPro. Works perfectly :-)
Bought it to debug my old 8-bit computer ORION-128, and probably to build my own. But that's gonna take some time...
