Latest UI for AR Drone .Net control library

October 17, 2010

Just a quick update on the latest and greatest revision of the drone control library. I added some instrumentation in an attempt to visualize the data coming back from the drone, some of these make sense, others do not – I’ll be tweaking as I wire up more of the data. A big shout-out to […]

It’s still early days yet, but I just completed my first successful test of a .Net Windows Forms control to control the Parrot AR Drone. I still need to pass in the Window handle of the control itself to use as the video rendering window, but so far it’s looking very promising. The code is […]

Doctor Who Live – why am I the last to find out about these things..?

October 14, 2010

Via Facebook, I just learned that the BBC has put together a live show of Doctor Who – think Christmas Panto with Daleks. I wish I could reproduce pictures, but I bet the BBC lawyers would be all over me… http://www.doctorwholive.com/ It’s a pretty cool idea, making a show about a show (about a TV […]

OK it’s official – too much cool stuff in the world…

October 13, 2010

This came today from Amazon – the Parrot AR Voyeurbot 1000. It is way too much fun, and makes you feel like you’re living in the future – populated by robotic Terminators. (If I were to make a plane or helicopter it would be like this – a button marked “take off” and a button […]

Way back, during the Second World War, prisoners of war learned how to build radios from whatever they could find. The “classic” way of building a rectifier was to use a pencil lead and a Gillette blue razor blade. By touching the blade with the tip of the pencil a very basic PN junction was […]

I’ve been working on adapting one of my failed Tesla coils into a crystal radio set to show the neighborhood kids. I’ve run into the #1 problem everyone faces – not enough antenna to generate a strong signal. I read somewhere that a “proper” AM antenna should be between 100 – 500 ft for good […]

I ordered a Wicked Lasers Spyder Arctic S3 back in June. It did take quite a while to ship – so if you order one, expect long delivery times. When I first read about them, I thought it was just over-enthusiastic marketing – a blue laser in the 1W range was difficult and expensive to […]

I managed to catch the online concert “live” from London (8pm UK time, 3pm my time) along with at least 5000 other people from around the world. What’s really nice about the ustream experience is they have live chat and a social network feed running alongside the playback – so people from around the world […]

Everyone has seen those plasma balls you get from Spencers gifts. They even make versions that plug into USB ports – although they do all look a bit feeble. You can create a hugely more dramatic effect by hooking up one side of a regular light bulb to 12,000V and a piece of foil to […]
