Wondering why @LowPowerLab Felix decided to use non-standard PCB thickness of 1.3mm on the Moteino M0, can't use a standard RPSMA connector
Non-standard PCB thickness of 1.3mm on the Moteino M0
PCB for ESP32 based smart thermostat controller project
PCB for ESP32 based smart thermostat controller project with touch bring-up success. The enclosure is in the works. Feeling satisfied. #IoT #smarthome
PCB revision for the ESP32 RFM69-to-MQTT gateway
Working on a PCB revision for the #ESP32 RFM69-to-MQTT gateway with TFT display. Added a piezo buzzer, htu21d TH sensor and a LDR for smarter screen dimming.
Prototype PCB for the RFM69 to MQTT IoT gateway
Prototype PCB for the RFM69 to MQTT #IoT gateway with TFT, RTC, atsha204 encryption and neopixel is ready, works well. Excited 🙂
RFM69 keyfob project, already planning for v2 PCB
Making good progress on RFM69 keyfob project, already planning for v2 PCB
IoT keyfob project PCB
Secure #IoT keyfob project PCB just arrived
Rewiring messed up SMD connections
Rewiring messed up SMD connections on prototype board
The YAPM PCB is done
The YAPM (Yet Another Power Monitor) PCB is done and preliminary tests pass – built between a new job and scarce hobby hours.
Funky v3 PCB populated
Funky v3 PCBs populated and briefly tested – double-row headers soldered on the test unit, first impressions of the new board.
The Raspberry Pi TFT PCB arrived
The Raspberry Pi TFT PCB is back from the fab – TFT soldered on, working on first try, small demo inside.
Raspberry Pi TFT board
Laying out a proper Raspberry Pi TFT board – a non-rectangular PCB that sits on top of the Pi, off to the fab house.
E-meter PCB ready
The e-meter PCB arrived and is coming together – a wrong 2×8 header footprint and two missing parts, otherwise looking good.
3D modelling of PCB designs
Turning Eagle PCB layouts into 3D Sketchup models with EagleUp – my boards rendered before the fab even ships them.
TinySensor 1.4 PCB is ready
TinySensor v1.4 PCB is here – now with a 3.3V FTDI connector for serial debugging, programming over it comes next.
RFM12b to serial PCB for my Pi
A small home-made PCB that permanently fits the RFM12B-to-serial module on my Raspberry Pi – simpler than the native SPI efforts.
TinySensor PCB is ready
15 TinySensor v1.3 PCBs arrived – RFM12B works, the ISP connector doesn’t (my mistake), programming on a breadboard for now.
Single sided ATtiny84 temperature sensor PCB
A single sided ATtiny84 temperature sensor PCB after the double-sided fiasco – etches cleanly, sends every 60 seconds.
Remote sensor’s PCB is a failure :(
The home etched PCB failed, and so did the kitchen sink – ferric chloride does not forgive. Lessons from a bad etching day.
Home made PCB for the remote temperature sensor
My first home-made PCB: toner transfer and ferric chloride etching for the remote temperature sensor board – faster than any fab house.
Sensing shield PCB ready
The Sensing Shield PCB is ready and partially populated – first tests looking good.
Arduino shield for energy monitoring
My first Eagle PCB project: an Arduino shield that turns the spaghetti heat pump monitoring setup into something orderly, EmonTX based.
