Open Problems

A list of open problems that I want solved, but don't have time time/ resources / patience / skill for. If you want to take a crack at any of these, feel free to contact me for details.

PS: I may be willing to offer bounties for successful solutions.

Markdown Wiki Topics

1. Static Site Converter

Github / Gitea / GitWeb Wikis are great for maintaining a lightweight wiki with text in a Markdown format. However there are some major shortcomings:

1. Appearance sucks. No way to customize, create sidebars, TOC etc

2. No search available

Solution Needed:

Create a jekyll-like system that will take all the markdown files from a git-wiki and convert to a static site.

Starting point:

Use the Ruby gem gollum-site to create the site. This has multiple problems - looks awful; no search; page links broken, etc. Can we use a good Jekyll theme like this and convert the existing markdown into a nice static site?

2. TOC Generator and "what-links-here" generator for Markdown Wiki

Problem: Gitea does not have an easy way to create a TOC. Maybe use a script to do it at each push / sync?
Like this: https://github.com/ekalinin/github-markdown-toc

"What-links here" is a very useful feature on MediaWiki. Perhaps we can use the same script to generate a sort of dict of all pages; then get a list of which pages link there; and then sort by page size / in-or-out links?

Problem.: This could become circular...!

A backwards FT232

Basically a module that can take commands from a RS232 and send them out on a USB line that has a FT232 on the other end.

Root problem: I want to control a USB-enabled power supply from a microcontroller

Power Monitor

Full solution:

Device to measure voltage and/or current, log it, then send it over some comms. Alerts / events for predefined events like over/under voltage.

Should have onboard RTC

Isolated Probe

100kHz bandwidth isolation amplifer that can be a substitute for isolated scope or isolated probe.

Ubuntu VNC Remains a major pain

Remote:

Run on the host machine:

x11vnc -rfbauth ~/.vnc/passwd

export DISPLAY=:0

xrandr --addmode DisplayPort-1 1920x1080_60 --output DisplayPort-1 --mode 1920x1080_60 --right-of DisplayPort-4

xrandr --output DisplayPort-4 --auto --output DisplayPort-3 --auto

Wireless no-setup water monitor / level logger

Basically what the title says

Adjustable Mandrel for Winding machine

A single mandrel that can be adjusted / modified easily to hold multiple sizes of bobbins / cores - thereby not needing to have one mandrel for each bobbin size

High BW current Sensing

Basically sortof replicate what Sumit has done for GaN sensing.

Low cost IR Camera + Boil detection?

No more spilt milk

Low cost Camera Trap / Bird Camera

Very small outdoor camera that can do visual + IR sensing.
