I’m putting together a shopping list on LCSC rn. So to understand what I should stock atm I will try to index some of my short/mid term projects. Also it’s good to write and keep track.

  1. Immediately I am designing a new LED matrix toy. I have prob around 2k 0603 green SMD LEDs that I got as a gift from a friend years ago… And I have a small assortment of Padauk microcontrollers, but only about 2 each for a given form factor/model and spec. I have cutout a breakout PCB for it, but have not expanded on that. I don’t see a programmable variant of my PMS134 so maybe I need to try using an external flash or something… I don’t have the proper resistors for this which would be 0-1k ohm and sub 0603. Voltage should also be dropped to like 2.2V but I seem to only have CR 2450s… These things use more power than a lot of coin cell applications.

  2. I’ve been planning to make a board for fabrication machines like specifically very cheap 3D printers… I’m inspired by the Teacup firmware and RepRap project. It should only need a simple M0 or RISC-V with DMA and serial buses. Maybe a ESP32-C3. Or there are many simple ARM solutions instead or as coprocessors for special functions maybe including locomotion control… Also consider some type of DAC system. Additionally this project could be accompanied by a special power supply unit.

  3. So also I want to make a high range mesh networking unit… So specifically I should find RF components for that.

  4. Future matrices. Future matrices will tend to use smaller LEDs (0403) and RGB LEDs. I found some small RGB LEDs (closer to 0603 but square) and I don’t have any 0403. I also prefer use smaller/cheaper micros with these with some buffered shift registers on the outputs. I’m interested in the Shenzhen Fuman Elec 74HC164D. Also future matrices will have larger LED counts and so they may need more extended memory, smaller components and more efficient components.

  5. I’d like to make a special PCIe card with lots of accelerators and IO. Or it could do anything but it’d be cool to make a PCIe card. And I have programmable logics sitting around.

  6. An SBC. An SBC possibly with a purpose in a product such as a handheld. Would be great experience to hook up an Allwinner or something on my own board if that is something I can do.

  7. I am still waiting on specific parts for my workstation. Would like to do more work on GEM OS on that system.

  8. I have a ton of stuff to do around the property. Need to put up a barrier and do landscaping and stuff and prepare for the planting season next year…

  9. Need to work on website stuff. I haven’t touched my servers in a while but I did switch off of Cloudflare CDN. I should maybe put up a lemmy and work on the git, IPFS, email and some other stuff.

  10. Should try to learn some softwares like Blender and FreeCAD. Maybe I’ll try to learn some chemistry. And I’ve tried to study some languages. Also I’ve been reading history like California wikipedia but don’t have much better than wikipedia.

  11. Should clean up and develop my room some more. Need to develop the desk system and my shelving, make more room for the workstation cabinet. And get some better lighting and plants and scenery.

  12. I’m considering prepping more and more. If I can farm decently enough maybe I can stash stuff and should order certain things while I can. I’m slowly running out of money and I need to consider things such as mining monero… I still want to make a stash in the mountains or something. And I can’t reasonably afford some transport like a motorcycle.

I’ll think of more stuff rn and I have more research and shopping to do. I’m going to go deep sea fishing with my bro, dad and his boss soon.
