DIY portable CNC machine
Want to show of your cool DIY CNC machine, but it’s just to cumbersome to take it with you? Here’s a portable DIY CNC machine (machine translation). Enclosed inside the plywood box is the CNC, along with a computer running LinuxCNC, a monitor, and an interface controller. The work area is 120mm/40mm/80mm in the X/Y/Z […]
Workshop Update for December 27th, 2012
Getting back from the holidays, new electronics toys in hand. Blog comments are much improved and all the server errors seem the be fixed. Posting a comment still takes 10-15 seconds though, so we ran the blog with some debugging plugins. No specific problem has been located yet, but we’re getting closer. Finished Beers in […]
DIY Theremin
Erdabyz want’s to build a DIY Theremin. This is a musical instrument controlled without direct physical contact. The device has two antennas which in conjunction with the operators body (representing the capacitance) complete two LC oscillators. By moving your hands closer or farther from the antennas, pitch and volume of the tone are controlled. My […]
A look at our spammer friends
The Akismet spam filter service we use on blog comments seems to be letting lots of spam through lately. We’re moderating all comments with links, as well as first time posters. That requires human interaction and increases lag between posting and seeing a comment, so we’ll continue to look for better options. Thanks to everyone […]
Unbricking a laptop with the Bus Pirate
Nbssss successfully unbricked his ASUS G74SX laptop using the Bus Pirate. He used a Pomona 5250 SOIC clip to attach the Bus Pirate to the offending BIOS chip while it was still soldered to the board. For those attempting this in the future, what worked was to connect the four signal pins to their counterparts […]
All Sick of Beige case sizes available at Seeed
All the Sick of Beige case sizes are now available at Seeed Studio for $3. This case is designed to be simple, cheap, and easy to assemble. The PCB is sandwiched between two laser-cut acrylic sheets, and the whole assembly is held together with aluminum screws and standoffs. The cases are compatible with standard PCB size […]
Workshop Update for December 26th, 2012
Today we continued to organize our free PCB drawer. We sorted PCBs and started a year-end inventory.
USB Infrared Toy v2 back in stock
USB Infrared Toy v2 is back in stock at Seeed Studio. You can use it as a remote control with your computer, view infrared signals on a logic analyzer, capture and replay remote control buttons. You can get IR Toy v2 for $22.05, including world wide shipping.
4 Channel electronic load
Need to test your power supply with a 20A capable electronic load? Gelbanana is designing just such a device. It’s an electronic load designed to spread the heat dissipation through 4 transistors each taking 5 Amps. So far he is testing the cooling system which consists of two massive aluminum heat sinks. Via the forum.
Paddle Clock free PCB build
Faultykyle built one module of the Paddle Clock, a clock kit project we worked on several years ago. The board consists of two 7-segment displays driven via tw0 ‘595 serial to parallel shift registers. The control and serial signals are routed to a PCB edge connecter, which was intended to to plug into the Paddle […]
DP6037 Protoboard v1 PCBs are available at Seeed
A multipurpose 0.1″ pitch prototyping board that fits a DP6037 acrylic case is now available at Seeed Studio. This one is pretty small, just 60mm by 37mm, bigger boards are on the way. We originally made this board for building up quick and simple reference circuits with through-hole chips, such as the DIP ARM chip […]
Christmas PCB giveaway
Today we built some boxes to help us organize the free PCB drawer. Hopefully we can get them out quicker than ever. Look for a stock update in the free PCB store soon. More on that soon. During the reorganization we stumbled across these 6 orphaned PCBs, and it seemed in the holiday spirit to […]
Quartz crystal breakout
Markus really liked the NU-XTAL quartz crystal breakout board, so he decided to build his own. He had one of our QFP protoboards laying around which had a small quartz crystal breakout on them. He cut it out, hot-glued, and soldered the pins. I like your idea of a plug-and-play XTAL solution for breadboarding. I […]
OpenPipe open hardware MIDI bagpipes
The OpenPipe crew designed a MIDI-USB shield for the Arduino that can turn just about anything into a musical instrument. To demonstrate the shield they built the open source bagpipes in the video above. Via Hacked Gadgets.
Multi-processor test board for open source USB stack development
An open source USB stack for PIC microcontrollers has evolved in the forum over the last year. It supports a number of USB-enabled PICs, and a good developer would test each chip before each release. We’ve been crowd sourcing that testing in the forum, but now prolific forum member Mats is designing a PCB so […]
