Raspberry Pi 5 support in Home Assistant 12
Finally Raspberry Pi 5 support in Home Assistant 12. Mine was starting to collect dust waiting for this.. https://www.home-assistant.io/blog/2024/02/26/home-assistant-os-12-support-for-raspberry-pi-5/
Raspberry Pi 5
Ordered 23rd of Oct 2023, received today #raspberrypi 5
3D printer bed level visualization
Interesting visualization of my 3D printer bed level using https://github.com/jneilliii/OctoPrint-BedLevelVisualizer/tree/master plugin for OctoPrint. Not bad, not great
Auto bed leveling kit for my Creality Ender 3 v2 3D printer
Auto bed leveling kit and other goodies for my Creality Ender 3 v2 3D printer. Should have ordered these ages ago
Raspberry Pi 5
Considering whether to buy the new Raspberry Pi 5.. who am I fooling, I know I'll end up getting it anyway. Resistance is futile

35 and 45 WiFi devices at home
How many WiFi devices at home is 'too many'? We have between 35 and 45 depending on who's home and which devices are active. A mesh network of four routers provides the needed coverage.
Wireless outdoor temperature sensor
Had to move a wireless outdoor temperature sensor I designed ages ago, noticed a memo inside I left for the future self with last battery change date. Still sending readings every minute since May 2018, thats 4 years and 9 months on couple AAs and still going strong. #IoT #rfm69
Washing machine over the air firmware update
Wife is complaining that the washing machine is performing an over the air firmware update, and cannot be used the next few minutes. She is not impressed. We live in interesting times.. #IoT
Raspberry pi display, piggy backs the RPI
Testing an interesting Raspberry pi display, piggy backs the RPI, has speakers, capacitive touch and 1024×600 resolution. Planning on using it as always-on home automation control center
Router upgrade and 3D printed a wall mount
Router upgrade finally arrives. Family of four working and studying from home plus 25 connected smart things made the old router unreliable. Planning on flashing Merlin. 3D printed a wall mount for the router Measurable speed improvements – new vs old router speed test
SAMD21’s internal temperature for sensorless room
SAMD21’s internal temperature seems pretty accurate to measure ambient temperature when on battery power/mostly sleeping. Experimenting with sensorless room temperature monitoring using #LoRaWAN
RTL-SDR monitoring the 433Mhz wireless packets
RTL-SDR monitoring the 433Mhz wireless packets send by my home automation nodes (RFM69 FSK) #IoT #SDR #homeautomation

pi+3.5″ 3D printed enclosure won’t close
Fail of the day: @adafruit 's pi+3.5" 3D printed enclosure won't close. I have their older 3.5" TFT+touch version though, this was designed for the newer one.
RFM95 with a simple 82mm wire as antenna
RFM95 with a simple 82mm wire as antenna has a much better range than the ESP32 TTGO LORA module with uFL antenna. Less is more? #LoRaWAN #IoT

64.4 dB noise level while 3D printing 3DBenchy
64.4 dB noise level while 3D printing #3DBenchy on my new Creality Ender 3 V2, mostly fan hum. Stepper motors are barely hearable.
Creality Ender-3 V2 3D printer
Just received a Creality Ender-3 V2 3D printer, my first. Hope it works well.
DA16200MODs, the new 70uA while connected to WiFi SoC
Just received couple DA16200MODs, the new 70uA while connected to WiFi SoC #IoT
DA16200 WiFi SoC
Interesting new WiFi SoC by @DialogSemi – the DA16200. Promises averaged 72µA power consumption and 1 sec response time while always connected to the network. Perfect for battery powered WiFi #IoT nodes. I will order few samples and research it further. https://youtu.be/d80X2GtTNBk
Lowpower listening on 433Mhz
Lowpower listening on 433Mhz while consuming 1.2uA. Range about 100m, reaction time about 800ms-1.5s. The node on the right sends data/awakes the node on the left upon button press, consumes 300nA in standby. Using RFM69 transceivers with Atmega328 and @LowPowerLab 's library More details under scope: the receiver wakes for ~250us every second, consuming 19mA…
Low cost monochrome 7 segment LCD display
Dug up an old prototype of a low cost monochrome 7 segment LCD display + DS18B20 temperature sensor + Atmega328 + RFM69 433Mhz transceiver project. 30uA sleep current. e-paper is still relatively more expensive alternative. #IoT
PCBs after soldering the components
Do clean your PCBs after soldering the components. Before/after power consumption measurements, the soldering flux, dust create tiny, invisible pathways for current to leak.. #IoT

Cheap PIR sensor
Testing a cheap PIR sensor, seems to be working fine down to 2.0V with no modifications (strange?). 25uA quiescent current at that voltage. Considering it for a battery powered PIR IoT node. Power consumption at 3.0V:

Toying with LVGL v7 on my Mac
Toying with LVGL v7 on my Mac in preparation for upgrading my embedded projects to that version. By the looks of it, it will take a few days of fiddling. Why do they make so many breaking changes? Had to go through the same hell when upgrading from v5 to v6; Deja Vu…
