A Printed Case for Your ESP Environmental Sensors
https://hackaday.com/2019/11/28/a-printed-case-for-your-esp-environmental-sensors/
We’ve said it before but it’s worth repeating: rolling your own hardware solution is ridiculously easy these days. If you want to make a network attached environmental sensor, you wire a DHT11 up to an ESP8266 and you’re done. Time to move onto the software. In fact, it can take …read more (https://hackaday.com/2019/11/28/a-printed-case-for-your-esp-environmental-sensors/)

When fiddling around with old computers, you can occasionally find yourself in a sticky situation. What may be a simple task with today’s hardware and software can be nearly impossible given the limited resources available to machines with 20 or 30 years on the clock.

A Division in Voltage Standards
https://hackaday.com/2019/11/28/a-division-in-voltage-standards/
During my recent trip to Europe, I found out that converters were not as commonly sold as adapters, and for a good reason. The majority of the world receives 220-240 V single phase voltage at 50-60 Hz with the surprisingly small number of exceptions being Canada, Colombia, Japan, Taiwan, the …read more (https://hackaday.com/2019/11/28/a-division-in-voltage-standards/)

Hacking Transmitters, 1920s Style
https://hackaday.com/2019/11/28/hacking-transmitters-1920s-style/
The origin of the term “breadboard” comes from an amusing past when wooden bread boards were swiped from kitchens and used as a canvas for radio hobbyists to roll homemade capacitors, inductors, and switches. At a period when commercial electronic components were limited, anything within reach was fair game.

Simplified AI on Microcontrollers

Artificial intelligence is taking the world by storm. Rather than a Terminator-style apocalypse, though, it seems to be more of a useful tool for getting computers to solve problems on their own.

DSP Spreadsheet: Talking to Yourself Using IQ

We’ve done quite a bit with Google Sheets and signal processing: we’ve generated signals, created filters, and computed quadrature signals.
