I just received an email from Parrot in France regarding potiential licensing issues with the ARDrone.Net library we plan on releasing this week. The essence of the communication states that developers are only allowed to release games using the official SDK from Parrot, and not other derivative works. A .Net SDK is in apparent violation […]

Tesla Coil running from 12V DC

November 6, 2010

I found a neat design for a pulsed 12V DC Tesla coil – unfortunately the website was in Hungarian, but I was able to figure most if it out. After fixing up a few dry joints, I managed to get it running… You can check out the original Hungarian site here: http://skory.z-net.hu/tesla/mini_tesla.html

November 5, 2010

I was recently looking to put together a high voltage DC power supply, after searching around online for the necessary components I realised that I would be better off trying to extract them from some redundant technology. One quick trip to my second favourite store – Goodwill – and I had all the parts I […]

Check out this amazing video of Rune Foshaug playing his laser harp live in his living room: I am a big fan of this guy – his music is great, and his synth programming is pretty awesome too. One of the problems with playing this piece is that there is very little tempo information in […]

As a follow-up to the recent information I got from Ryan – I just received an email from Johan Peters in Belgium: Hi, I read your page and noticed you didn’t have any info on the new laser harp which Jarre uses for his Europe tour (probably a tour in the US in 2011). The […]

Still too much cool stuff in the world

October 24, 2010

As if phone-controlled drones, and pocket sized death-ray lasers weren’t enough… Another impulsive buy from Fry’s: (Got to stop doing that).

Someone recently described this effect to me, and it does seem to work. I put together the above image in Photoshop. It’s based on the classic chessboard illusion.

It looks like being a full time Dad is going to seriously impact my ability to get the ARDrone.Net library fully functional. I’m therefore looking for a couple of people to take over working on the codebase. We all get an equal share of the cred. I decided to do it this way rather than […]
