These are my ongoing arduino project.
Working on 3 cell po2 monitor with HUD.
I use modified smither code for HUD with tri color LED.
Depth and temperature sensor seems working fine but still need watertight case for real dive test.
Control solenoid is very easy with Arduino.
More hard part was getting high pressure solenoid valve.
After long wait, I got 1500 PSI & 3900 PSI valve which I’ll install to water separator and filter housing (I have a Bauer Junior 2).
The water separator’s thread is 1/4 BSPP but P0 (triplex) filter housing need special adapter like this.
to be continued.
Just add 2l steel set on my micro.
They’re light on land, heavy when underwater makes perfect for drysuit dives and looks awesome too. I will probably use it more then 3l set for a short dive.

This is update version of my DIY nitrox analyzer based on Arduino compatible board.
It’s using small oled display and powered by 9v battery. Display o2 percentage of gas, sensor mv output, two MOD(maximum operating depth) in meter. 1 push button for lock screen, calibration, po2 change.
OLED 128×64 I2c display module
I put everything include sensor in a small plastic box(65×95×55mm) with transparent cover. Here’s some image of ugly looking inside. I’m sure someone can 3d print smaller and prettier shell.
9v battery is very poor choice for Arduino project (I used because that’s what I have many). AA, AAA x 3 or small rechargeable batteries are better.
Warning! Be cautious when you use 9v battery. Arduino onboard DC regulator will be destroyed if you accidentally switch positive & negative.
