Show HN: I built a handheld CHIP-8 game console to teach myself embedded systems A while back I wrote a CHIP-8 emulator (which is considered the Hello, World! of emulators and is more accurately a virtual machine since historically CHIP-8 was an interpreted language running on top of the COSMAC VIP to make game programming easier). But a few months ago I got really interested in embedded software, so decided it would be neat to port my emulator to a STM32 MCU and design a console around it as a learning experience, since CHIP-8 never existed as a physical system. I didn't know much about embedded software when I began, and even less about electronics, but I managed to write all the firmware from scratch and even designed my first PCB, resulting in a finished (though not very polished) handheld CHIP-8 console. For those curious, the GitHub repo also has links to my dev blog about the project as well as a build guide. Thanks for looking! https://ift.tt/Ay9jNuw July 20, 2022 at 03:12AM

Show HN: SVG stroke-dashoffset interactive examples SVG stroke-dashoffsets have always confused me. I couldn't never figure out which way the line was going to move as I increased or decreased them. So I made some interactive examples to help. https://ift.tt/AWuMpzr July 19, 2022 at 12:31AM

Show HN: PubKey – Communicate Privately in Anonymous Public Spaces https://ift.tt/wOUjMoL

Show HN: PubKey – Communicate Privately in Anonymous Public Spaces A little while back I remember seeing a user on a certain anonymous imageboard asking for an invite to a selective email host. Only after a few minutes did the guy realize the perplexity of the situation. How do you insure against a race condition in a public forum with no way to direct message? Luckily, he nabbed the invite code, but it got me thinking about using PGP to provide a solution. This is meant to be a rough PoC and the UX is definitely not ready for the average Joe, but the functionality I'd like to think is there. What catbox.moe is to dropbox is what I'd like this to eventually be to keybase. Btw, "this page uses NO SERVER" just means it's static. I'm not trying to fool anyone lol.
