A project log for Me building projects from hackaday.io

This is where I build and talk about projects designed by the great people of this community.

#Snail Mail Notifier by @Solenoid

This is a long time shelfie, because I never had the 0805/0603 parts - and I'm not done yet. I'm just now able to use and program the receiver as a digispark. Rewarding hacking around though. I hope I can get some decoding of weather stations going. This is one of the first boards I got from a member of this community, and I like that very much. And by the way, look at those diodes! And of course, the LED is in backwards 🙈

An interesting link I found, where the digispark is being used as a crude oscilloscope, takes PIN 2 as an input, which is coincidentally the same pin the data goes on the 433MHz.

And some cheat sheets, since I always forget:

Glad to see it works, if you have any feedback it'd be welcome. For the LED I drew a small bar indicating where it should point, but it seems it wasn't explicit enough.

I published the code for the original purpose of this project, but still haven't gotten around to deploy it yet...

It's just me googling pinouts of smd leds and failing everytime with a 50-50 chance :D I couldn't get the python stuff for the oscilloscope working yet.
