Arduino-based “Analog” slow cooker controller
https://www.electronics-lab.com/arduino-based-analog-slow-cooker-controller/
Dan Ternes blogged about his Arduino-based controller for analog slow cookers: With the AC power control figured out, I considered the User Interface. I opted for something simple. The Adafruit RGB LCD Shield would work well as it had both a display and buttons built in. Sure, I could have beat this project about the […]

Homemade x-ray inspector reveals PCB secrets
https://www.electronics-lab.com/homemade-x-ray-inspector-reveals-pcb-secrets/
John McMaster has written an article detailing his homemade x-ray scanner: In some previous posts I talked about getting an x-ray head working, reverse engineering an x-ray sensor, and working with LinuxCNC. In this post I put them all together so that I can take a bunch of x-ray snapshots across an entire PCB. This […]
Simple and small temperature fan control
https://www.electronics-lab.com/simple-and-small-temperature-fan-control/
Xristost published a new project, a simple and small temperature fan control: I published this schematic long ago in this article: Adjustable power supply and since then I made some improvements in PCB to make the board as small as possible. The idea is to be easy to attach the whole board to the heat […]
Toshiba launches 256-Gbit 48-layer 3-D NAND flash
https://www.electronics-lab.com/toshiba-launches-256-gbit-48-layer-3-d-nand-flash/
by Susan Nordyk @ edn.com: Ready for sampling in September, Toshiba’s 48-layer BiCS (Bit Cost Scalable) flash memory stores 256 Gbits using a 3-D vertically stacked cell structure and 3-bit-per-cell triple-level cell technology. By employing this 48-layer vertical stacking process, BiCS flash surpasses the capacity of conventional 2-D NAND flash memory, where cells are arrayed […]

Arduino Chess Clock
https://www.electronics-lab.com/arduino-chess-clock/
by benhur.goncalves @ instructables.com: Hey folks! After making an Arduino smartwatch just last week, I received many complaints,or tips, to use a RTC (real-time clock) module. That’s because the Arduino timer is not very precise, it can lose a couple a minutes along a full work day. Luckly, I had one of those modules at my […]
