This prototype cycle for my temperature and humidity tracker is almost complete with a new 50% slimmer case. It's been quite a journey #electronics #kicad #esp32 #micropython #blender #3dprinting

More tests: x2 devices reporting overnight. One on my desk and the other by a window that gets morning sun. Graphs made in #Grafana. Devices are ESP32C3, Sensirion sensors and running #Micropython. Testing a smaller battery, hence diverging battery readings. #electronics #ESP32

@PaulStoffregen's enquiry on a previous post motivated me to take a *real* macro photo this time around. The solder paste photo is an image stack shot through 100mm macro lens.

2nd custom sensor board created and working đ.1) macro shot of solder paste .2) parts placement in progress.3) finished and functioning.#electronics #esp32 #micropython #kicad

Temperature and humidity sensor dev continues on the software front. Sleeping the hardware for 4s between reads yields ~34.5 hour life with a 1100mAh battery. Going to try caching data on the device and connecting/sending across the network less often next. #esp32 #micropython.

Made a little case for my custom temperature/humidity sensor board. Feels like a really real prototype now âşď¸. #3dprint #blender #electronics #esp32 #micropython

Social media loves graphs right?.Logging humidity, temperature and battery voltage with my custom ESP32 board is working nicely. Guess where in the graph I switched from USB to battery power. #esp32 #electronics #grafana #micropython

It's a miracle. My custom esp32 board is working. #micropython installed and now playing with various features. #esp32 #electronics

From pictures on a screen to real PCBs a few days later. I'm all setup to try some new assembly techniques. Stencil paste application and reflow on a cute hot-plate. Feels like it should be easy. That's usually a sure sign I have no idea what I'm doing! #electronics #esp32

Learning from previous mistakes and making sure parts fit before PCB production. #esp32 #electronics

I'm really just setting the ground work for posting a video of me screaming "WHAT IS YOUR MAJOR MALFUNCTION" at a PCB.#FullMetalJacket.

"This is my schematic. There are many like it but this one's mine. My schematic is my best friend. It is my life. I must master it as a must master my life.".Entertaining the idea of making a project board with an ESP32_C3 module. #esp32 #electronics

RT @matt_trentini: The May Melbourne MicroPython Meetup is on this Wednesday, the 28th May!. We'll have a bumper news roundup since we didnâŚ.

Testing this neat little #Sensirion SCD30 CO2 sensor on a breadboard at the moment. First thoughts: I live in an atmospheric cesspit! In the background is a #Pico2. Made fast progress with the help of #MicroPython.#electronics
