Bio Computer

at 8:07 am. Filed under Computer Hacks, Funny Hacks

 

Most of our workplaces are built using wood, metal and plastic. Adding some plants can go a long way to make the space a bit more comfortable. Have a look at the Bio Computer over at Total Geekdom. In this design the computer is used to help heat the soil to promote germination.

 “I started wanting to use the heat from a computer as a way to warm the soil and help with germination/growth. I’m about as far from a botanist as it comes, I did some reading online and became pretty interested in the effects of soil temperature on germination/growth. I read different studies and papers from various universities. It was not too long into that process that I became hooked on the idea of using computer heat as a way to control the soil temperature of some sort of living plant life. “

FTA Dish converted to receive KU-band

at 8:55 am. Filed under Complex Hacks, DIY Hacks

 

Like so many people these days David Prutchi has a space communications array in his back yard. His modification of his FTA dish allows it to be used to receive Ku-band transmissions from geosynchronous FTA satellites as known-Az/El beacons.

“The Fortec Star 120 dish is small enough to be handled by a Yaesu G5500 Az/El rotor, yet provides 21.7dB gain in the L-band, and 27.7 dB gain in the S-band.  In addition, it provides enough gain for the Ku LNBF that good FTA satellite reception is achieved despite the polarization mismatch that results from Az/El aiming without a dedicated geosynchronous horizon-to-horizon motor.”

US Military Experimental Flying Platform from 1955

at 8:41 am. Filed under Insane Equipment, What Were They Thinking

 

This US Military Experimental Flying Platform from 1955 is like a flying Segway. I wonder how long it will be before we have a modern day version of this. With technology that is becoming common place because of devices like the AR Drone I think the time is close since the stabilization technology would be quite trivial these days.

Constant Current Dummy Load Project

at 5:22 pm. Filed under DIY Hacks, Electronic Hacks

 

George Graves built this Constant Current Dummy Load Project based on this blog post over at the EEVBlog. It was built from a single sided board which was designed using ExpressPCB. That software is very nice to draft something up fast and it allows for an easy screen grab to etch what you see quickly.

Thanks for sending this in Jim.

“The only change I really made was running the opamp at 8 volts (7808) for a bit more range. It seems happy at 1 amp. Two amps and things start to really heat up.”

Heavylift Hexacopter Build

at 11:05 pm. Filed under Complex Hacks, DIY Hacks, Electronic Hacks

 

Jacques Sperwer from Jacques Productions in the Netherlands shows us how he is building his Heavylift Hexacopter. Have a look at the video footage of the windmill below to get an idea of what these copters can do. This build is using a Wookong control system which looks to have all the bells and whistles. 

 

“Wookong Multi-Rotor stabilization controller is a complete flight system for all multi-rotor platforms for commercial and industrial AP applications. Unlike others, WooKong allows the use of regular ESC commonly used in RC helicopter without any wiring modification; Heli mode setup providing a seamless transition for current Ace One AP professionals. WK-M utilizes high quality components precisely calibrated with temperature compensation in all gyros and sensors, industry renounce flight algorithm in autopilot and UAV. IMU damping system is rated for gas engine best in the class.”

Light Trikes at the Bay Area Maker Faire

at 11:15 pm. Filed under Complex Hacks, Cool Gadgets

 

If you are in the Bay Area you better be checking out the Maker Faire this weekend. It is running May 19th and 20th. The Light Cycle above from Frog is sure to be a big crowd draw! This device is loosely based on the light bikes from Tron, the two players are back to back riding one their own light cycle and has a dedicated view, this is a great spectator project since there is a center screen which shows the aerial view of the playing field. The bike is based on a Schwinn bike and was hand welded by the crew. The electronics are Arduino based and are networked together to allow sharing of game sensor data.
