Resys is an LED drawer system that makes it easy to find your resistors

You’ve got your design ready to go, you know you have the right components… but where exactly did you place that particular resistor? With the Resys drawer system by Lynlimer, you no longer have to wonder — just type in the needed value and the proper drawer lights up automatically.

The device is based on an Arduino Nano, with an LCD display for text output and a numeric keypad for value entry. The proper drawers are lit via WS2812B addressable LEDs, held in 3D-printed holders. 

It’s a clever project that could be expanded to well beyond the 16 drawers now used. Code, STLs, and circuit diagrams are available in Lynlimer’s write-up if you want to make your own!

Before Nintendo and Atari: How a black engineer changed the video game industry forever

Atari. Magnavox. Intellivision. 

Each evokes memories of the golden age of video games, which brought the first wave of consoles you could connect to your home television.

But there’s an oft-forgotten person from that era whose contributions to the industry still resonate today: a black engineer named Jerry Lawson.

Lawson oversaw the creation of the Channel F, the first video game console with interchangeable game cartridges – something the first Atari and Magnavox Odyssey systems did not use.

Sapphire Announces Two 4×4 AMD Ryzen Embedded Motherboards

Sapphire has introduced two new miniature motherboards based on AMD’s Ryzen Embedded V1000/R1000 APUs. The new platforms are designed for the most compact highly-integrated machines for industrial and commercial applications.

Sapphire’s NP-FP5 and BP-FP5 compact motherboards feature a 4×4-inch footprint and are based on AMD’s Ryzen Embedded V1000 or R1000 APUs, which offer up to four Zen cores, an integrated Radeon Vega GPU, and a TDP of up to 25 W. The actively cooled systems support up to 32 GB of DDR4-2400 memory using two SO-DIMMs, feature one M.2 slot for an SSD with a PCIe 3.0 x4 or SATA interface, and one M.2-2230 slot for a Wi-Fi module.
