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.

If you want a small touchscreen as a Linux display, the usual choices are to build a whole Linux computer into it or treat it as a dumb remote framebuffer. Sergey Zorin took a third route. Woodland X11 is an experimental X Window System server that runs directly on an ESP32-S3, so ordinary Linux X11 programs open their windows on a cheap touchscreen.

A wall-mounted tablet can run the whole house, but sometimes you just want a button. Reddit maker Zweetkonijn built his own Home Assistant remote control with a custom PCB, a 3D-printed case that looks a lot like a Google TV remote, and an ESP32-H2 that talks Zigbee. Total material cost was about 40 euros, and the post passed 900 upvotes on r/homeassistant in half a day.
Why the ESP32-H2…
Most bedside clocks are either too bright to sleep next to or too dim to read. Reddit maker udota wanted a soft white clock that does not light up the whole nightstand, so he skipped the LEDs entirely. His build throws the time onto the ceiling using nothing more than a 1.3 inch OLED, an ESP32-C3 and a single glass lens.
The OLED is the light sourceCommercial projector clocks usually…
Reliable robotic manipulation requires more than vision, particularly when handling soft, fragile or irregular objects. Cameras can locate an object, but tactile sensing provides the contact information needed to determine how firmly it is held and whether it is beginning to slip. Microchip Technology (Nasdaq: MCHP) has introduced the ATFCD52 high-speed capacitance digitizer to convert signals…
A stepper motor can reach its target while the robot joint it drives is still in the wrong place. That gap comes from backlash in the gearbox, and it is the reason cheap 3D-printed robot arms feel sloppy. Arctos Robotics, the maker behind the open-source Arctos arm, built CLMD, an open-source ESP32-S3 stepper driver that reads a second encoder right at the gearbox output and corrects the joint…
Thousands of Lenovo ThinkSmart View displays were built for Microsoft Teams calls and are now turning up second-hand for very little money. They have no battery, decent microphones and a speaker, and they are designed to stay switched on. Reddit maker m_s_ik turned one into a dedicated Home Assistant voice assistant and wall panel by replacing Android with a minimal Debian and a single program…
Most people who want a flight tracker on a desk reach for a Raspberry Pi and an HDMI screen. Reddit maker Virtual-Bet-4566 went the other way: a 1986 Apple II monochrome monitor, a classic ESP32-WROOM-32 and exactly two wires. The green phosphor CRT now shows a live radar view of the aircraft overhead, and no video converter sits in between.
