Today I've "opened" further 50 Moscow metro tickets. I was looking for RFID chips made by Sitronics-Mikron.

Milky way 108199*81503 gigaphoto or 65500*65500 should be enough for anybody

Few 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 Chemiluminescence

As 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 programmer

Just 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...

Got a quadcopter on my birthday
Quite hard to control despite on-board gyroscope, robots will rule the world.

BLλCK MESA is done

What a great game :-) It's so interesting to see same places from Half-Life 1 being creatively re-made. Xen part is missing, but I hate it.
