Building an e-bike battery from some random trash is a terrible idea. You won't electrocute yourself, but you are very likely to burn down your house when one of these cells randomly decides to ignite.

I'm a senior software developer interested in low-level, performance, algorithms. I built a custom computer (including a CPU) from scratch and a C11 compiler for it. Please hit me up with jobs in Rust, C or C++.

> If you have a full 32-bit number and you need to divide, you can simply do a multiply and take the top 32-bit half as the result.

Can someone explain how this can work? Obviously, you can't just multiply the same numbers instead of dividing.

ynoxinul | 1 year ago | on: Ask HN: How do you organize your electronic components?

For though-hole components which I use with my breadboard and for small bolts, nuts and washers I have glued together a few dozen matchboxes and inscribed them with component description. For SMD resistors/capacitors I use an organizer box. Components within a certain range go into the same compartment together. For example, I have three compartments for resistors: ≤1k, 1k..≤10k, >10k. SMD ICs are all in one box, each type in its own plastic bag, inscribed.

I also have a registry of everything I have. When I buy or use something, I update the registry.

You can replace the controller board all together, the electrical interface should not be that hard. You have to spin the spindle, jiggle the heads and send/receive the data. The main problem I see here is that modern hard drives have enormous, unimaginable information density. There must be so many tricks how they achieve that (and do that reliably!). You have to re-trace the steps the hard drive industry has made in the last 50 years.

I have a CS/applied math background, my main job is software development, so I don't have problems with the software part. If you are interested in compiler design specifically, you can find a lot to read or to watch online.

When building my system, I was inspired by 8 bit retro computers like ZX Spectrum. Their architecture is straightforward and easy to understand.

Electronics just fascinates me, but I can't really point out a single source which gave me the insight. A lot of playing around with transistors, microcontrollers, logic gates gives the intution how to design stuff.

I'm sending my long frames out to the network and no OS I have has any problem with that. I've read somewhere that long frames are actually used by some routers to store metadata after the packet.

> I know there are some compilers one could try to port but my ISA is kinda esoteric so not straight forward

Same. I tried digging into exsiting compilers, but they are either unsuitable at all or too complicated (clang).
