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
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
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
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
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… More pictures at Ezprezzo.com
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
Got some extra floppy drives lying around? Why not put them to good use and build a RAID drive out of them! That is exactly what Scott Fudali did. Check it out here. Here are the hardware specs: * iBook G3/700MHz * 384 MB of RAM * Running OX 10.4.3 * 13 VST Floppy Drives * 6 USB 1.1 Hubs (Not all ports were used though)
