For more than a decade, a roughly 30 dollar USB dongle has been the way most people start with software-defined radio. Engineer Patrick Quirk now argues in a detailed post that this era is ending, because the tuner chips inside the cheapest SDRs are going out of production. He found out while designing a Raspberry Pi CM5 carrier with an SDR on board, when the radio chips it needed could not be…
Capturing HDMI video on a Raspberry Pi, for a PiKVM-style remote console, a stream box or a test rig, has long meant a TC358743 bridge board limited to 1080p at 30 to 60 frames per second. Engineer adouglass52 has released three open-hardware HDMI to MIPI CSI-2 boards built around the Rockchip RK628H that reach 4K30 and 1080p120 on a single 4-lane link, with drivers that run on standard…
Blind and low-vision people today mostly rely on a white cane or a guide dog. Maker DebackTech wanted to see if a low-profile wearable could add a sense of the space around them, and built a pair of glasses with three small LiDAR sensors that turn distance into touch through 16 vibration motors sewn into a shirt. He then tested them in downtown Boston and in a blindfolded game of catch.

Filming a bumblebee in flight at high speed is hard because the bee will not stay in a tiny, razor-thin focus zone. Maker and engineer Jeremy Fielding spent about a year building a robot that solves this: a cinema camera on a motorised rail that finds a bumblebee, follows it and keeps it in focus automatically. The finished rig was shipped to a bumblebee research team in Berkeley, California,…
Being away at sea for months makes even simple things like "where is he now?" hard to answer. Reddit user mrnks13, who is about to spend nearly four months on a ship from France to Singapore, built his girlfriend a small answer to that question. It is a wooden birdhouse with an ESP32 inside, a three-colour e-paper map that shows where his ship is, and a thermal printer on the roof that prints…
Reddit maker MrShatanas found four large old circuit boards in a garage and decided they were too good-looking to throw away. One of them is now a piece of sci-fi wall art: a 3D-printed frame packed with lights, a slow-motion fan and a pointer that answers YES or NO to your questions. A single Waveshare ESP32-C6 board with a built-in 1.47 inch LCD runs the whole thing.

Engineer adouglass52 designed a custom compute module in the Raspberry Pi CM4 format, built around the Rockchip RV1126B, a vision processor with a 3 TOPS NPU. With the first boards just back from JLC, the maker ran it against a CM4 (CM4101000) on the same carrier board with the same two IMX415 cameras, using stock tools on both and the median of three runs.
What is on the boardThe…
Bourns today announced the Bourns® CRT-G Series General-Purpose Precision Thin Film Chip Resistors for circuits that require accurate resistance values, low temperature drift, and stable long-term performance. Available in package sizes from 01005 through 2512, the series provides resistance tolerances as tight as ±0.01 % and temperature coefficient of resistance (TCR) options as low as ±2 ppm…
Most hobby quadcopters fly on an off-the-shelf flight controller running Betaflight or INAV. Maker tynix5 went the hard way instead. The 5 inch quad, called No Fly Zone, flies on a flight controller PCB that the maker designed and hand-assembled, paired with a handheld remote built on a second custom PCB. All of the flight and remote firmware was written from scratch, and the full write-up,…
If you are planning a product launch, a production run or a large kit order for 2027, microcontroller and sensor lead times are a real constraint. In its Q3 2026 Trendliner, published in August, distributor Avnet Silica lists lead times of 26+ weeks for every MCU class it tracks, for MPUs, and for sensors and actuators. That is six months or more between placing an order and getting the parts…
ROSCon India 2026 will take place from 2-4 December at the JN Tata Auditorium, IISc Bengaluru, and Circuit Digest will be there as a Media Partner. If you work with ROS, build robots, or are just getting into robotics, this is one to know about. It's a gathering of India's ROS community, and it's been growing every year since its first edition in 2023.
The 2025 edition in Pune recorded…
Most Meshtastic nodes end up either in a pocket or stuck on a window, and each needs a different case. Maker Koosh designed one pocket-sized node that does both, with swappable back plates, and posted the files on Printables with a full bill of materials. The post on r/meshtastic passed 280 upvotes in under a day.
The hardwareThe node is built on a RAK19003 base board with a RAK4631…
