Raspberry Pi 4 SSD/HDD case
I created this case for a Raspberry Pi 4, POE HAT, 2.5′ Hard Drive and a SATA to USB adapter. There is a slot on the IO side of the case that can be used to store the excess cable…

Bench power supply
I designed this simple bench PSU to have one variable DC output and 2 x USB A ports. It’s based on a 19v 65w Dell laptop power supply that I had lying around but I wouldn’t recommend this route to…
Creality Ender 3 V2 PSU terminal cover
I remixed is because the original design didn’t have enough width for the cables to exit the PSU compartment. The original power supply cover for the Ender 3 v2 (and v2 neo) restricts the airflow to the power supply so…
Monitoring a Raspberry Pi with Python, InfluxDB and Grafana
Inspired by this guide, I wrote this script to send system stats to InfluxDB 2.0 for a Pi that’s running as my off site backup server. More info about that project (with 3D printed case) in this article. While this…
ESPHome whole home power monitor
This AC power monitor can measure the current flowing over any mains power cable. It’s based on a Wemos D1 Mini (ESP8266 micro controller) and a 100A:50mA split core current transformer. For this project, we will use the ESPHome add-on…
Pi NAS (Raspberry pi 3 B+ with 2 x 3.5′ HDD’s)
I designed this Raspberry Pi NAS to connect two 3.5′ HDD’s to a Pi 3B+. There is a DC buck converter for the Pi so you don’t need to have a separate 5v power supply. With the current design, you…
Air quality monitor (MQ 5/7/135 based)
An ESP8266 mini based air quality monitor. Please note that this should never be used to replace a proper CO monitor and should be used for informational purposes only. Head on over to Thingiverse to grab the .stl files to…
Ender 3 v2 Neo 80mm mainboard fan shroud
This shroud allows you to replace the stock 40mm fan with an 80mm fan for Creality Ender 3 v2 series printers. Since the fans on Ender 3 v2 Neo’s run on 24v, I wanted something that would let me use…
Ubiquiti Access Point UFO (remix)
This is a remix of this design so credit to funkysod. I have remixed it to add four holes that align with the holes in the mounting bracket for my Ubiquiti Unifi AC LR access point. I’m pretty sure this would fit…
