The attiny24/44/84 doesn’t have a hardware uart, it has a Universal Serial Interface (USI) which if I remember correctly is more or less just a shift register with some extras. I also thought all tinys had a UART, until I tried writing code for a project I designed that used the tiny44

The bus pirate developer has a custom cable builder, but it looks like the lead time is a few weeks

porkbun is nice. I use them for domains not available through cloudflare

The G7 is like all in one so it means throwing a battery and transmitter away every use which I’m not a fan of. The adhesive patches it comes with also aren’t as good imo, plus the range is worse, and I get erratic readings more often. It is a lot smaller and simpler to apply so those are positives

I love the idea of “circumcising” the battery! Was curious how it connected to bat-. Re: infusion sets, that’s basically what happened with me, just using whatever they gave me when I switched from Medtronic. Was wondering if I was missing out on better. Idk about the Omni cause it requires ur phone

Woah that’s a cool setup. What’s the pwrtop? Could be very useful for me because I already have lots of 18650’s laying around from my years of vaping. Also what infusion set do you use? Do you like it? What sensors do you use currently? I just switched to G7 and they kinda suck compared to G6 tbh

I’ve started using typst after learning about it from one of your skeets a while back and I’m a big fan. I’m now using it for my resume and service records for my vehicle!

It compiles to an assembly language (PAL III) which I’ve also written an assembler for. It was much simpler and also very fun to write. It generates instructions for a custom PDP-8 that I built with discreet logic chips. Also a lot of fun!

I attempted to write a C compiler for my PDP-8. Well technically it’s a C -> PAL transpiler. Furthest I got was unary, binary, and trinary operators. It supports 12-bit “integer” variables and a single main function that takes no arguments and returns an int. Code generation was probably the hardest

This is so cool, I’ve been wanting to recreate it since watching the video. I’m hoping you’ll do a video about the galvanometers you ordered, that seems to be the way to go
