I got into Audiobooks this year. I first listened on headphones or just phone loudspeaker (thought it's OK for voice). Then I bought JBL Go 3 and it's a different experience. The speaker is compact, lightweight and has a nice design. Sound quality / loudness is fully sufficient for voice and does a great job for its size for music as well. It's waterproof, now I listen even while showering. The only downside is lack…

I used a JBL Flip 4 speaker to listen to audiobooks and podcasts while floating in the pool for a while. Bluetooth doesn’t penetrate more than a few centimeters into water, so I’d just put my phone in a dry bag, tie it to the side of the speaker, and set it adrift. Way less clunky than a headset and worked great

I got the JBL Flip 6 for audiobooks! I compared the 4 to the 6 but the 6 had two tweeders that really allowed for crisp narration.

CO2 Monitor to let me know when I need to let some new air into my office. Mine is a TFA Dostmann 31.5009, but any model with an NDIR sensor should be fine, there are many choices around 70-150 EUR.

SCD30, your microcontroller of choice and your own code.

I have CO2 measurement working with an old third party 3.3v Arduino clone, and a nice 4-digit 7seg amber display.

CO2 poisoning is very common. It leads to fatigue, headaches/migranes and concentration issues. Most people don't recognize it and try to cope with caffeine & pain killers. I noticed that sitting in a tightly closed office surrounded by monitors , CO2 was being trapped around me . I started testing with blood oxygen monitor and could reliably predict low blood O2 based on the above symptoms. tl;dr keep your door and/…

Keeping door and windows open while it's very cold or very hot outside can lead to extremely high heating/air conditioning bills. Meanwhile, high quality energy recovery ventilators that can exchange air with the outside without ruining your insulation tend to be a lot more than $200.

I meant the door to your office.

IronOS is actually a firmware, not a classical operating system. The soldering iron is like many modern appliances a smart device and contains a RISC-V CPU on which the firmware runs. I bought a Pinecil as well this year, and it's really a great tool, and I dare say much more versatile and powerful than many traditional soldering stations which cost much more.

Got it, thanks! That makes way more sense to me.

I’m sorry but I still don’t get it either. If it’s hot enough, you’ll know it’s ready when it starts melting whatever you use to solder. Why would one need anything more?

A Nutr machine so I can make quality nutmilks at home instead of buying store bought stuff loaded with nasty preservatives and very few nuts per serving.

Do you do oat milk? Wondering if these devices avoid the gel-like consistency that forms when I make it in my blender.

I've been wanting to get a CO2 sensor for a while now, but I want one that interfaces with Homebridge or directly with Homekit. I'd appreciate any recommendations!

Mila has it built in and the added benefit of being an air filter. Works with Homekit and can alert you.

Do you know of any that support HDMI 2.1 properly for 8K 60 Hz monitors? I currently just have a USB switch and two HDMI 2.1 cables, and manually change the input on the screen each time.

Don't do that, do this: https://haim.dev/posts/2020-07-28-dual-monitor-kvm/ - free and works great!
