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.
Finally was able to take a photo of JupiterAfter many weeks of bad weather in Moscow I finally was able to take a photo of Jupiter with my 500m/F8 mirror lens.
To the left side of Jupiter - Europa and Io, to the right - Ganymede. Callisto was very faint, and didn't fit into the frame (that's because it has albedo 0.22 compared to 0.63-0.67 for Europa and Io). Current distance to Jupiter is 685 million of kilometers.
I had to tune brightness curves separately for Jupiter and it's moons because Jupiter was too bright.
Filed application for my project "Zeptobars" to SkolkovoThe idea of the project is to design and manufacture (on existing fabs) general purpose microcontrollers (just like AVR, PIC, STM32 and others), but of course better and cheaper That is the reason I was doing decapping of various microchips last months - I needed to find out cost of manufacturing of existing products to see if it's commercially viable.
Why microcontrollers and not "yet another innovative IT startup"? I believe market is full of IT startups, and business in adjacent areas is more viable. Days of offsore software development which I was heavily involved in are numbered - mainly due to rapidly closing gap of salaries of good developers between US and Russia. Only large and well-established offshore development companies would survive what's coming.
Few words about SkolkovoContrary to popular belief (in Russia), Skolkovo is not an magic box full of government money. Being Skolkovo resident (if I would manage to get one) only means that you can pay less taxes for some time, and less hassle dealing with customs. The trade-off is more bureaucracy (Skolkovo controls every ruble you spend) and certain limitations (project must be executed in Russia, there are some legal things which you would not be allowed to do).
They don't really give all the money to the "poor innovators"- according to their grant policy, without co-investing they can invest 5 mln. roubles max (~125k$), larger sums require co-investor who would invest 25-75% of the total budget. This is understandable - 100% government funding is prone to corruption and would yield companies which are not ready for the world-market.
So, effectively Skolkovo is just a "sweetener" for usual investors - they throw in fraction of the money, offer some cooperation, but do not get any ownership in the company.
Let's see how it would work
Scanning electron microscope of my dreamWanted to get to SEM microscope for quite some time. Finally it happened:
Modern Russian military microelectronics
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...
