I'm working on building my own function generator!

If you're not an EE - a function generator is a pretty common piece of electrical engineering lab equipment.

I've got all the source files up on GitHub - feel free to take a look: https://github.com/cushychicken/bfunc

I've also been keeping a weekly project journal. I just posted the latest installment today if you'd like to see what I've gotten up to: http://cushychicken.github.io/bfunc-weekseven-log/

I'm already planning a second prototype and board spin with more functionality.

If you need or want a really bare-bones function generator for your home lab, get in touch! Instructions for how are in the post. )

Meta: This thread is fun to read, it's cool to skim through such a large variety of ideas and projects. I wouldn't mind seeing it as a monthly thing like the "Who is hiring?" posts. There'd probably be some overlap with Show HN, but I personally wouldn't mind if it's just once a month.

Seconded

In Germany there's currently a govt-sponsored hackathon going on, with lots of ideas to help with the Corona crisis https://wirvsvirushackathon.org/ (German only).

It's massive (42k volunteers signed up) and keeps crashing slack, but it's also lots of fun.

I'm working on a PoC that helps with triaging cases and tracks them in an ITSM tool.

I'm trying to make Python's `pathlib.Path` something you can readily subclass and use for S3/FTP/whatever: https://discuss.python.org/t/make-pathlib-extensible/3428 Currently working my way thru a bunch of preparatory bugfixes: https://docs.google.com/spreadsheets/d/1TicFDMudKKA6CZcrscg1...

We had this exact issue with VisiData, and had to resort to some not-great hacks. Thanks for your work!

Hmm, its quite a list. GPS Disciplined 100Mhz clock source. I've got the QRP Labs "fake" temperature controlled synthesizer, an Icebreaker FPGA board, and an Adafruit ultimate GPS with 1PPS output. Reminder/message board which is two parts, a server that monitors a file for messages and puts the top 8 on an LED sign in my office/lab. A set of transponders that generate messages for the file. And a 'grooming' process…

Polyphase DSP is some fun stuff. I helped a coworker implement a polyphase lowpass filter in Verilog a few years ago. Would like to get back to learning about it one of these days. (Hopefully an impending layoff doesn't give me the time I need to do that!)

Why'd you choose 50MHz for push/pull capability? What does application does that high of a drive frequency unlock?

Log storage and search system for structured logging data in Rust. i.e a database optimised for logs and log-like data and nothing else. Existing solutions are too inefficient for the use case of logs (TB+/day), suffer under high field cardinality, are based on costly and unnecessary full-text-search systems that aren't well optimised for logs data or just plain and simply can't handle structured data and degrade to…

I have a similar goal with this project, a multi-tenant log storage and retrieval system: https://github.com/notduncansmith/loghive

The idea is to shard the data by logical domain and by time segment, so that queries only apply to relatively small and efficiently-read data, and to exploit the embarrassingly-parallel nature of the problem.

I bought an old trench coat from a thrift store and outfitted it with 350 programmable LEDs , an Arduino to control them, and a 24 AA battery bank for a music festival last year, it was a hit. I'm currently working on adding another 150 LEDs, fixing the power system (I burnt out the Arduino after a couple hours), and looking into adding a microphone and learning some sound programming to make the suit change colours to the beat for this year. I always wanted a living technicoloured dreamcoat.
