Glen Akins writes about their latest project:

Building a Set of USB-Controlled Analog Panel Meters Using the Silicon Labs EFM8UB1

I’ve always liked the way these little HUA SO-45 analog panel meters looked, but, given the long lead times from China, I’ve never ordered a set. This fall, I changed my mind and finally decided to order a set. While they were in transit to the United States, I designed a small board to control them over USB using a Silicon Labs EFM8UB1 Universal Bee 8051-baeed microcontroller.

Design files for this project are in Glen’s usb-analog-panel-meters repository on GitHub.

Here's a complete write up of my USB-controlled analog panel meters project! Four 10mA analog panel meters all under USB control using a vendor-defined USB HID class. Features @oshpark boards, the @siliconlabs EFM8UB1, and @TXInstruments DACs & opamps. https://t.co/sgvIcWvTr9
