Collaborate Disseminate
Adding an audio channel to your microcontroller project can mean a pile of extra components and a ton of processing power, as a compressed stream must be retrieved and sent …read more Continue reading Digital Audio for Microcontrollers Doesn’t Come Much Simpler Than a WART
One of the main advantages of cheap wireless modules is that they get used in consumer electronics, so if you know what’s being used you can build your own compatible …read more Continue reading Hacking A Solar Inverter RF Interface
As amazing as CircuitPython is, it hasn’t yet been ported to any 8-bit microcontrollers. [Chris Heo] was unsatisfied with his inability to use Python on his 8-bit ATmega4808 AVR, so …read more Continue reading Python Runs Through A Zombified 8-Bit AVR
[Carsten] spent over a year developing a small CPU system, implementing his own minimalist instruction set entirely in TTL logic. The system uses a serial terminal interface for all I/O, …read more Continue reading Minimal UART Computer
The basic test instrument suite — a bench power supply, a good multimeter and perhaps an oscilloscope — is extremely flexible, but not exactly “plug and play” when it comes to diagnosing problems with some common hardware setups. A problem …read more

The streaming box allows arbitrary code execution as root, paving the way to pilfering social-media tokens, passwords, messaging history and more. Continue reading Authentication Bug Opens Android Smart-TV Box to Data Theft
Have you ever wanted to watch someone reverse engineer a piece of hardware and pick up some tips? You can’t be there while [Jeremy] tears open a Netgear N300 router, but you can see his process step by step in some presentation charts, and you’ll get a few ideas for …read more
While the full steampunk aesthetic might be a bit much for most people, those antique gauges do have a certain charm about them. Unfortunately, implementing them on a modern project can be somewhat tricky. Even if you’ve got a stock of old gauges laying around, you’ve still got to modify …read more

Pity the poor TTL computer aficionado. It’s an obsession, really — using discrete logic chips to scratch-build a computer that would probably compare unfavorably to an 80s era 8-bit machine in terms of performance. And yet they still forge ahead with their breadboards full of chips and tangles of wire. …read more

Really, how did we get the point in this world where an exercise bike can be bricked? Such was the pickle that [ptx2] was in when their $2,000 bike by Flywheel Home Sports was left without the essential feature of participating in virtual rides after Peloton bought the company. The …read more
