The forgotten and procrastinated projects thread

A thread to discuss all those projects we’ve wanted to do for ages but can never find the time, energy or money for.

I’ll start.

1. I’ve wanted to write a textbook. For ages I’ve had it in the back of my mind. Most maths degrees have a very similar structure and content in the first year regardless of the university. So I was thinking of writing one textbook that would cover nearly all of that material. You see maths degrees are very flexible. By the second year usually no modules are compulsory. So what’s the point in buying a big textbook on subject X if you are only going to study the the first few chapters?
2. I would really like to try book binding. There is something extremely satisfying about watching the binding and decoration of a hefty hardback book.
3. I would like to make my own laptop. Not just a kit. I’d like to design my own motherboard, possibly using FPGAs
4. I want to make my own GPU compute cluster. With one or two mother boards each with multiple graphics cards. Only I want it to look cool like a supercomputer from an 80s sci fi. I was thinking of mounting the mother boards and GPUs on a wall behind a clear plastic plate instead of in cases. Maybe with a lot of flashy LEDs run by a raspberry pi.
5. I want to make my own online dating app.
6. I want to make an app that will let you use a wifi router to turn near by phones into a ‘PA system.’ I was thinking you could use it to run events like silent discos or public lectures in public spaces so you could run stuff without a venue. (Which is tough to get for small community groups)
7. I used to have this free game that came with a computing magazine that was basically a naughty video game for groups of consenting adults. Think truth or dare but more sexual and the computer picks the dares. Any way the hardware that ran it is obsolete so I’ve had several abandoned attempts to code my own version of the game.
8. I’d like to make my own drone, ultra light. Basically just a PCB with everything, even the motors, surface mounted.
9. I want to make my own personal radar scanner to ‘see through’ walls. There is one that can use wifi signals bouncing off things as a source so it should be possible to do legally.
10. I’d like to try my hand at ladies fashion design. Especially lingerie. It’s about the only thing that would actually motivate me to do a textiles based project.
