The Lovebox is a project I learned about through a Make: magazine article from 2019. A reader notified ThingPulse – of which I’m a co-founder – because the project’s Arduino sketch relies on an open-source display driver provided by ThingPulse. I was immediately intrigued as the project involves electronics, software and classical woodworking. As a […]
If you’ve been following my blog or have occasionally been reading my IoT articles the name “WeMos” should be familiar to you. I wrote a number of articles about that Chinese manufacturer’s family of devkits based on Espressif WiFi chips. The latest offering is a devkit that is heavily “inspired” – ok, you may call it […]
WeMos D1 mini Lite…again I find myself writing about WeMos IoT products. The D1 mini series now consists of the regular 4MB D1 mini V2.x, the 16MB D1 mini Pro plus the 1MB D1 mini Lite. ESP8285(!) 11 GPIO pins, all except D0 support interrupt/PWM/I2C/one-wire 1 analog input (3.2V max input) 1 Micro USB connection 1MB […]
The ESP8266 chip is specified to support up to 16MB external SPI flash memory. Yet, ever since ESP8266 modules that actually use more than 4MB flash memory became available folks started wondering how to make use of the space beyond the 4MB boundary. The WeMos D1 mini pro you see on the left is by […]

My friend Squix and I compiled a list of questions to Ivan Grokhotkov Director of Software Platforms at Espressif. Ivan is one of the main drivers behind the ESP8266/Arduino project. Early in […]
