I previously documented my odyssey to find the “best” earphones for me. For the past 18 months or so I’ve been using RHA T20i monitors with over-ear hooks and here’s my verdict. By the way, the reason I eventually replaced my beloved Klipsch earphones that I had been using for years before was the rustling cable […]
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 […]
I’m an avid proponent of free and open-source software (FOSS). All the open-source services and applications I offer are of course free but I accept donations (i.e. donation-ware). The inflow of PayPal donations is very moderate but that’s alright. Fortunately I don’t have to live off of that – I would have long starved to death. […]
I’ve contributed to a Docker image for a The Things Network (TTN) gateway recently. Pure joy! It helps to have your own TTN LoRaWAN gateway up in no time – once you assembled the hardware that is. I wrote a post about how to build your own gateway for The Things Network and what I […]
Self-charging robots sorting system helps Chinese delivery company finish at least 200,000 packages a day in the warehouse Chinese delivery firm is moving to embrace automation. Orange robots at the company’s sorting stations are able to identify the destination of a package through a code-scan, virtually eliminating sorting mistakes. The army of robots can sort […]
Issues around privacy and freedom are very dear to me but they’ve come under a lot of pressure in recent years. So, it’s no surprise I was hooked by an article with the catchy headline “Why I told my friends to stop using WhatsApp and Telegram. Even with end-to-end encryption Big Brother is still in […]

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 […]
Does your a** ever get jealous of all the sh** that comes out of your mouth?
Catch a rare glimpse of the life behind the secrete doors of Espressif, the manufacturer of the IoT rock-star chips ESP8266 and ESP32. 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 […]
