Furby Resurrection

at 9:08 pm. Filed under DIY Hacks, Electronic Hacks, Toy Hacks

Mondo Technology has hacked a Furby in a different way. They scrapped all of the existing controllers and started from scratch.

“The mechanism of the Furby itself was designed around micro- controllers. It has one motor that runs the eyes, mouth, and ears in sequence. Two sensors are provided from the motor servo system: one counts off about 200 pulses for the entire sequence, the other is an ‘index’ pulse that lets you find the start/end of the sequence.”

TTL Chip TIG Welder

at 9:05 pm. Filed under DIY Hacks, Electronic Hacks, Insane Equipment

David Barrett has taken TTL logic to the extreme! No his logic isn’t controlling a photocopier, printer or some obscure computer equipment. David’s TTL handywork is controlling a 180 Amp TIG Welder.

“Many modern welder front panel’s were looked at and many dozens of spec sheets studied to gain a list of requirements, then it was simply a case of reproducing those function’s simply and cheaply.
The descision was made early on to build using descrete I/C’s for three main reasons. Firstly they are easy and cheap to obtain for anyone wanting to copy the design.
Secondly Microprocessors are great and simplify things a geat deal but one has to have programming knowledge and the equipment neccesary to actually get the firmware into the chip….not everyone has either.
And thirdly if fault finding is required descrete TTL and CMOS is far easier to troubleshoot with average home type test equipment (VOM, Freguency Counter, Oscilloscope etc)”

Big Dog by Boston Dynamics

at 7:02 pm. Filed under Complex Hacks, Crazy Hacks

Big Dog is fantastic looking machine being created by Boston Dynamics. DARPA is funding development of Big Dog, they have also funded development of the Tree Climbing Robot.

“BigDog has an on-board computer that controls locomotion, servos the legs and handles a wide variety of sensors. BigDog’s control system manages the dynamics of its behavior to keep it balanced, steer, navigate, and regulate energetics as conditions vary. Sensors for locomotion include joint position, joint force, ground contact, ground load, a laser gyroscope, and a stereo vision system. Other sensors focus on the internal state of BigDog, monitoring the hydraulic pressure, oil temperature, engine temperature, rpm, battery charge and others.

So far, BigDog has trotted at 3.3 mph, climbed a 35 degree slope and carried a 120 lb load.
BigDog is being developed by Boston Dynamics with help from Foster Miller, the Jet Propulsion Laboratory, and the Harvard University Concord Field Station. Development is funded by the DARPA Defense Sciences Office.”

Scratchitti (edge-lit) Rune Clock

at 12:18 pm. Filed under Electronic Hacks

Theodore Johnson has created an interesting clock that uses edge lit plexiglass tiles. It would take some time to be able to read the characters since Theodore decided to use Eldar Futhark runes as his numbers. Probably no harder to read than an LED binary clock though. This is not the first clock he has built, actually this is just one in a long line of other neat clocks!

“I could create the scratches using a straight edge and a scratch awl. The next problem is what to engrave. Even the thin scratches tend to obscure the figures behind them, suggesting that I would have better luck if I created numerals from segments. Further, the segments should be straight, not curved. I could create a seven segment display, but that would be boring. Instead, I decided to use Eldar Futhark runes, using the first letter, Fe, for one, and so on to the ninth letter Hagall for nine. To be traditional, I represent a zero with a blank. With a little creative overlapping, I managed to represent these nine letters with only nine non-overlapping straight segments.”


GameBoy ATAPI CD Player

at 2:22 am. Filed under Computer Hacks, DIY Hacks, Electronic Hacks, Game Hacks

Jordi Bracke has gone about playing a CD the hard way. Instead of buying a $20 portable player he decided to interface a GameBoy system to play a CD using a computer ATAPI CD-ROM drive.

Here is what you need to build your own:
-A GameBoy to show track information and control the playing.
-A GameBoy cartridge: we will need it to interface the GameBoy to a board.
-An ATAPI drive to play the CD.
-A 12v-5v power supply.


Computer Delivery Chain

Ever wonder why your computer parts arrive with a few scratches on them even though they are brand new? Well not all computer manufactures use state of the art delivery chains…

Swimming Snake Robot

at 6:02 pm. Filed under Complex Hacks, Cool Gadgets, Insane Equipment

How would you like to discover this robot swimming with you in a pool? Even though it is totally robotic there is something about the shape and movement that would raise my hairs.

“Powered by a lithium-ion battery, the ACM-R5 is a radio-controlled amphibious robot designed to move like its real world counterpart. It can slither or swim underwater for 30 minutes on a full charge. Inside, you’ll find an intricate sensor system (attitude/torque), small-sized camera, and a 32bit micro controller.”

Here are a few more links of additional information, the pages will have to be translated though.
