With the chip shortage I could not source the ATMega328P (mc used in Arduino Uno) so I’m going straight for some different AVR micro controllers.

ATTINY 84A-PU
ATTINY 84V-10 PU
ATMEGA 168A-PU

Just ordered some AVR micro controllers! Excited to expand on Circuit Python Raspberry PI Pico skills to more bare metal / C.

Hard Coral Genus Identification Guide by Zoe Richards super nice.

Сегодня я делаю сырники на завтрак 🥞!

Magnesium dropped from 1300ppm to 1200ppm, just inside the recommended range. I think because of the new lights, more coral growth, and since I do less water changes. Added Red Foundation C to my auto dosing setup. Hopefully it will recover to 1300 over the next month.

The more I learn about CAN bus the more I want to try it out. Not so much to connect to a car but to connect serval micro-controllers together. I'm thinking about splitting my aquarium controller project up into parts that would communicate over the wire.

How I fight Aiptasia:

1. Prepare clean work station / put on gloves.
2. Meld a small ball of D-D AquaScape Korallenkleber together, ~4min.
3. Load a tiny bit of Red Sea Aiptasia-X into the syringe.
4. Have Masha begin a syphon directly over the Aiptasia to suck up any spores that may still escape.
5. Dose the Aiptasia-X giving 2-5 seconds for the Aiptasia to ingest it and start dying.
6. Press in ball of Korallenkleber into the rock completely covering the area.
7. Continue to siphon off water from area.

First upgrade to my reef tank of 2022!

Goal: Increase the light reaching the coral to improve growth. Making the change very slowly to avoid any bleaching.

New setup: Now my two AI primes LED lights have been integrated with a Giesemann Steller T5 bulb light fixture. Hybrid T5 + LED provides a more even illumination while maintaining shimmer.

The Giesemann was sourced from the Munich Reef Aquarist What’s App chat group. Then I shortened it with a manufacture kit. After added the LEDs and hanging it on my existing ceiling cables all that is left is hooking it up to my DIY controller.

Not every day a Hackaday article reaches into my life. We were unable to pay with visa card at a few different shops last month because of this. 💳

Reminds me of my college philosophy courses.

During our trip to Alonissos my dosing containers ran dry. Without alkalinity or calcium stock solution my parameters plummeted. Even after slowly bring them back up I lost a few coral. ☹️ .

Happy to say now thing are back to normal and corals are growing again. Not exactly sure how to prevent this problem in the future but for now I've just set reminders on my phone to check the dosing containers more often.

Here is a screenshot of configuring Multideco

Found some useful tools for planning out gas management on technical dives.

Lastly if I had all the 💸, a rebreather. The Kiss Sidewinder.

mCCR because as a software engineer I would rather trust my life to a mechanical engineer. The company KISS of the mission. The sidewinder because Edd Sorenson dives one rescuing countless people in the Florida caves.

Of corse you need a BCD to stay afloat. Also out of Poland the company XDeep is making some epic products. Tested by cave divers and the like.

My sidemount capable BCD would be the XDeep Stealth Tec 2.0

Enough lift for stages or CCR, tough, streamlined, and easy to travel with!

Gear, gear, gear! No research would be complete without comparing tones of different types and companies.

I was surprised to find so many great diving products coming out of Poland. With reasonable prices. This is my current regulator top pick.

Tecline R2 Tec1 Sidemount set.

https://katalog.tecline.com.pl/en/regulator-r-2-tec-sidemount-set,3,5147,3468

The price is right and it has all the needed features for sidemount adventures.

Sidemount has really captured my imagination. I love the idea of having extra gas and flexibility underwater. If we move more towards technical diving I think the setup has a lot of advantages over backmount doubles.

#scuba

Ten levels deep on the scuba research. It started with the idea to look into regulators then expanded into hours of sidemount and rebreather videos and articles.
