Moppyduino, is a 6 channel Arduino based M_usical Fl_oppy controller PCB: Moppyduino is a M_usical Fl_oppy controller PCB based around the Arduino. The code is provided courtesy of Sammy1Am.
Workshop Update for February 21st, 2013
Today we recorded and wrote up the earlier video post about the TM220A pick and place machine. We also worked on the 3D models for the Bus Pirate educational kit. The previous breadboard model was inaccurate, and too rough for our liking, so we designed one from the ground up (SketchUp screenshot above).
TOP242 power source for 10W LEDs
Mincior over at Electroni-city built this DIY TOP242 power source for 10W LEDs : Inside the case of a regular wall charger with a 500mA transformer I’ve built a source in commutation for powering 10W LEDs by using a TOP242 integrated circuit in the primary part and the LM393 dual comparator on low voltage.
Mini breakout board for 18-pin PIC16F series microcontrollers
Embedded Lab designed a mini breakout board for 18-pin PIC16F series microcontroller: This mini breakout board is designed to simplify prototyping and experimentation work with the popular 18-pin PIC16F series microcontrollers. It is small in size (1.95″ X 0.75″) and is breadboard friendly.
WORKSHOP VIDEO #56: TM220A table top pick and place overview
Today we take a look at an inexpensive pick ‘n’ place machine found on the Chinese auction site Taobao for 22800RMB (about $3,600). A pick and place is a machine that puts electronic components onto a circuit board that has been coated with solder paste. To complete the prototype you just place the populated PCB […]
Macroblock MBI5030 starter board
Macroblock MBI5030, is a 16 channel constant current LED driver with PWM output, and a SPI-like interface, it requires external grayscale clock though. The problem: you need the chip to figure out if your code actually works. And you also need the LEDs to see what’s going on – if at all. You could use […]
DIY USB power strip
Kenneth Finnegan posted his DIY USB power strip build: In any case, now I’m down my most-used USB charging port, and a Chumby. I considered simply replacing the power supply and carrying on, but having a few more bed-side USB ports would be handy. I therefore opted to build myself a USB power strip.
Workshop Update for February 20th, 2013
Workshoped a few part kit ideas. Mounted and reflowed the passives onto a Bus Pirate v4 with the TM220A. Will have a workshop video about it tomorrow. We also designed a Sick of Beige test rig holder. It features holes for all sizes of Sick of Beige standard PCBs. Both square and golder rectangle shapes […]
Synthesizer oscillator debugging with the Bus Pirate
Fortysevenfx tweeted: PySide -> BusPirate -> SPI = pure control magic :) It’s a prototype of a synth oscillator, here’s the digital core under debugging. Get an assembled Bus Pirate for $30, including world-wide shipping. Also available from our friendly distributors.
Bluetooth network monitor shows you stats
This bluetooth network monitoring device by Zak Kemble shows network statistics on a small LCD screen: Whenever I want to see why a download is going a little slow or getting lag on an online game I’d have to log in to my routers web page or SSH in to see if its someone else in the […]
PCB a Week 9: MrRef voltage and current reference
Mats continues his challenge of designing one PCB every week. This tool helps check the accuracy of your multimeter: The design might be interesting anyways since it has remote sensing for compensating for voltage drop in the cables. But if your meter is drawing enough current to cause more than a 1 mV drop you […]
Open source STM32 book
Open source STM32 book at Indiana University: Lucky students at Indiana University might like to enrol on the [C – H]335 Computer Structures course run by Geoffrey Brown. If they do, they will be treated to a great introduction to the STM32 processor. The lab manual for the course is freely available to download. The […]
Asus Laptop saved with the Bus Pirate and flashrom
Ph1ph1l0u successfully recovered his Asus Laptop using the Bus Pirate and flashrom: You have no idea how I’m happy too ;-) yes biosflasher, it’s a very GREAT soft, very usefull and very efficient ^^, and also for Bus Pirate: a cheap device, but how is usefull and efficient, a real GREAT device. Thanks a lot all […]
Workshop Update for February 19th, 2013
Cleared final hurdles to Bus Blaster v3 and v4 availability. Look for them in a few weeks. Finalized a special Bus Blaster batch made for MIPS. Setup a group buy of 7 TM220A pick and places. T-shirts will be back soon. Maybe even a whole Dangerous Fashion line!
Bit-tech make your own Raspberry Pi case competition
Bit-tech is holding a Raspberry Pi case making competition: We’re offering you the chance to win your very own Rasberry Pi Model B. All you have to do is build your own case for the Model B Rev 2. Of course, we’re not just talking about sticking it to a piece of acrylic or cardboard. We […]
Import Eagle boards into FreeCAD
Christian Aurich created a FreeCAD macro that imports Eagle board XML data into FreeCAD: The common solution until now is to export your board with eagleUp and assemble it with a case in Sketchup. This also gives you some drawbacks. The most important to me was that the Sketchup files are mesh based like the data […]
Smoke Tester v1 free PCB build
TomKeddie built a Smoke Tester v1 free PCB. It’s a board designed to safely power your prototypes, and check if they have a short somewhere using just about any available supply. Via the forum.
