After near a year, it have grown quite a bit.
From just one meter, variable transformer and oscilloscope, to full bench with wave generator, self made capacitor bank, "universal" counter, and all types of Unitra Nixie Multimeters. All from 70's and 80's. Even the camera is from that years and still works great.

Old ENI CD V-700 6b upgraded to a scintillator detector
This modification kit, paired with a Mk.1 scintillation probe has given my old CDV 700 which previously was not functioning due the high voltage circuit issue new life. I thought about repairing it, but then thinking about the cost and time involved in that an upgrade sounded like the best option, and it makes the unit way more sensitive to gamma radiation than the old Geiger counter was. The fact that it’s Arduino based also allows for further tweaking. It’s an understatement to say that I am quite happy with the unit, I’m actually very excited about it. It works extremely well and Nick at RadView has been very helpful throughout the process of upgrading my CD V-700 answering questions that I had on his discord support forum. I’m not receiving any compensation I am just a customer that wants to see him succeed at making innovative, useful radiation detection products. He makes other things as well including the alpha hound. Check out his website below. I also made a short video of my modification.

Ever since I started designing PCBs, one thing I really struggled with is getting the real world parts I want to use into my design software, it's only recently that I got to a nice workflow with my tool of choice Autodesk Fusion, here is a tutorial on...

Modifying generic automatic cat feeders to much simpler web interface using ESP8266!
I got so fed up with the stupid interface on the front of my automatic cat feeders that I decided to make a web interface and use the ESP8266 to control them. They are very simple devices. Across two different brands of feeders I have they use the same internal mechanism, so this should work pretty universally across all generic-looking cat feeders... I was going to design a custom PCB but the circuit is so simple it was pointless and would've taken weeks to arrive. I cut the original wiring harness and crimped on JST-XH connectors to make it look somewhat professional. cat feeder from brand #1 wired to my board cat feeder from brand #2 wired to my board The prefboard I made (I made 3x of them) You can check out the code and some more images of the feeders and board (front/back/etc) here: [link] [comments] |
