Tutorial on modifying servos for continuous operation

How to modify standard servos for continuous operation. This hack involves opening up the servo, removing the limit mechanics, and modifying the feedback pot. In his second tutorial Andrey shows how to add a rotatory encoder to the servo, for position feedback. It will stand still with control pulse of around 1,5ms (mine likes 1515us; […]

Fixing the EDID ROM of a monitor using the Bus Pirate

Matthias fixed the EDID ROM of his Samsung monitor using the Bus Pirate. He documented the whole process on his blog. Also included is a tip on how to connect the Bus Pirate to I2C line through the VGA, or DVI cable. This post is about fixing a broken EDID ROM in a monitor. There […]

Half Ohm adapter for multimeters measures small resistances

Half Ohm is a adapter for multimeters that allows you to measure resistance in the milliohm range. The project is open source, the design files are available in KiCad. Half Ohm milliohm adapter is ready! Multimeter adapter that transforms any multimeter into a precision milliohm meter and debugging device. Notice that your multimeter is useless […]

Replacing resistor arrays with single 0603 resistors

If a project calls for resistor arrays, but all you have are singles and mad soldering skills, you can try this hack. Yoganerdnl used a bunch of 0603 resistors on their side to replace the resistor arrays on his Bus Pirate SOIC DIY edition board. It takes patience and a steady hand, but it’s a […]

Digitaly enhanced vintage music box

A digitally-enhanced vintage music box: “Digital Enhancement” is an interactive sound installation consisting of an electrified Symphonion Brevet No. 28, a synthesizer, an amplifier and four headphones. The Symphonion musical box dates back to the beginning of the last century and its mechanical workings are combined with digital technology to convert it into a MIDI […]

Bus Pirate 802.15.4 ZigBee sniffer tools

Bruno hacked his Bus Pirate to be a ZigBee sniffer. He built a small protoboard adapter that connects the Microchip MRF24J40 module to the Bus Pirate IO header. He also wrote custom firmware that captures IEEE 802.15.4 traffic, and passes it on to a custom client app over USB. Check out his wiki page for […]

Reverse engineering car parking sensors

James decided to reverse engineer car ultrasonic parking sensors. These sensors have integrated electronics that handle all the measurements. They are connected to the car’s internal computer via a low-speed single wire CAN network. James provides pinouts, protocol interface, and some source code to interface with them. Since I know a thing, or two, about […]

Pager network snifffing

Kenneth tapping a pager’s output to sniff pager traffic. He bought an old pager and was happily surprised that he could easily tap into the demodulated digital signal. A little poking around between the circuit boards and Google and I found that this pager uses the Toshiba TA31142 FM detector specifically designed for pagers.  What […]

Re-purposing an LCD from a cheap picture-frame key chain

Here is a hack to extract, and use the LCD from a cheap picture-frame key chain. The project involved desoldering the LCD from its mainboard and building a breakout for it. With the help of a DSO it was possible to find out the pin-out for the LCD. The AVR library used to drive this […]

Nook Tablet hardware protection hacked with the Bus Pirate

The Nook Tablet hardware protection was hacked with some help from the Bus Pirate. The Bus Pirate was used as a simple USB to UART bridge so nook hackers can talk directly to onboard ICs and bypass the standard bootloader. The device was released  allowing ADB to be accessed.  Barnes and Nobel quickly patched this […]
