What can you do with a cheap Linux machine with limited flash and only a single free GPIO line? Probably not much, but sometimes, just getting root to prove you …read more Continue reading Getting Root on Cheap WiFi Repeaters, the Long Way Around
Many of us have used UARTs to spit data from one system or chip to another. Normally, for quick and dirty maker projects, this is good enough. However, you’ll always …read more Continue reading MUDLink Is Making UART Data Links More Reliable
We always can use more tools for FPGA debugging, and the Manta project by [Fischer Moseley] delivers without a shadow of a doubt. Manta lets you add a debug and …read more Continue reading Manta: An Open On-FPGA Debug Interface
Proximity sensors are common enough in automation projects that we hardly give them a second thought — pick something with specs that match the job and move on. But they …read more Continue reading Souped-Up Reflective Sensor Uses Itself for Wireless Programming
As more and more electric vehicles penetrate the market, there’s going to have to be a proportional rise in the number of charging stations that are built into parking garages, …read more Continue reading Reverse Engineering Reveals EV Charger Has a Sense of Security
[Etienne Sellan] got one of these lovely $5 logic analyzers. As with any shiny new tool, he started looking for things to investigate with it, and his gaze fell on …read more Continue reading Anyone Can Be The Master Of This Master Lock Safe
Teaching people efficiently isn’t limited to transmitting material from one head to another — it’s also about conveying the principles that got us there. [Mara Bos] shows us a toolkit …read more Continue reading Boards For Playful Exploration Of Digital Protocols
We ran an article this week about RS-485, a noise resistant differential serial multidrop bus architecture. (Tell me where else you’re going to read articles like that!) I’ve had my …read more Continue reading The Virtue of Wires in the Age of Wireless
The hobbyists of the early days of the home computer era worked wonders with the comparatively primitive chips of the day, and what couldn’t be accomplished with a Z80 or …read more Continue reading Retro Serial Terminal Uses Modern Chips to Get CP/M Machine Talking
The Musical Instrument Digital Interface has a great acronym that is both nice to say and cleanly descriptive. The standard for talking to musical instruments relies on a serial signal …read more Continue reading You Can Send MIDI Over I2C If You Really Need To
