Fresh hacks every day
A complete microcontroller development kit for little more than the cost of a bare chip? That’s what STMicroelectronics is promising with their STM8S-Discovery: seven dollars gets you not only a board-mounted 8-bit microcontroller with an decent range of GPIO pins and functions, but the USB programmer/debugger as well.
The STM8S microcontroller is in a similar class as the ATmega328 … Read the rest
Cable management is a headache for all, and if unmitigated it becomes a playground for cats. [kws103] posted a project a while ago that takes care of the messy wires for electronics on pull out shelving. Channel bracket is used to house the cables and has been articulated in three places to facilitate the movement of the sliding shelf. … Read the rest
The Stimmmopped is an electronic guitar tuner made to be used as a guitar pick. This uses two LEDs synchronized to blink at the exact frequency of the string you are tuning. Pluck the string with the corner of the PCB and then shine the light on the string you are tuning. As the vibrating string moves back and forth … Read the rest
[Jonathan Ward's] pcb mill is as impressive as it is inexpensive. Twenty-six plywood parts, labeled A-Z, are used to assemble the machine along with the customary precision rods, stepper motors, and router assembly. His bill of materials prices the unit at $458.18, a small price to pay in order to forgo a multi-step etching process.
His test board shows … Read the rest
While we have our fun ethically hacking, its very easy to forget that sometimes our ideas could be used with malicious goals. Take for instance SparkFun’s BlueSMiRF – the device’s original intention is simply to act as a wireless serial cable replacement. After hackers discovered several PIN pads use a serial interface, they put one and one together to … Read the rest
Move over Steve and PEART… there’s yet another robotic drummer in town. [Fauzii] tipped us off to his own MIDI-controlled creation – WizardFingers. According to him, WizardFingers is already capable of 64th note rolls at over 250 beats per minute. That’s on every drum simultaneously. Each drum is hit with a lever attached to a linear pneumatic actuator. … Read the rest
