I liked the web better when it had more than half a dozen sites.
I have but one bit of practical advice for hobbyist electronics designers: If you use a part, print out the datasheet PDF and save it in a binder. Better yet, set up a datasheet binder for each project you attempt, and put a copy of the datasheet for every part you use in the project into the binder.
I'm so fucking sick of madmen being given power by the malicious ignorance of the lowest people in society. I would cheer on a revolution if I thought it would be any better, but frankly I see no reason to think that.
How can I focus on my insignificant little project when fascism is rising like a tidal wave in a sewer? Because it's the only thing I can do to stay sane.
Hard to believe if you're young or just getting into electronics design, but once upon a time, a politely worded letter or phone call could get you free samples of almost any chip made at any company.
So. I need eight people. Eight people who are excited to bootstrap a whole new platform. Eight people who have the time and skills and willingness to pay USD$149 plus shipping to lay hands on a Sentinel 65X revision 2 developer edition board. These things will have every known flaw fixed, but I can't guarantee they don't have flaws I don't know about yet. That's why it's a developer edition: your contributions will help make it ready for general release in quantity. In exchange, you get your own board, fully populated and ready to program, my undying gratitude, and any help I can give getting started with Calypsi and the development environment as it grows. This is as close to getting in on the ground floor as you're going to see. If that seems like your kind of thing, let me know here, 'cause we can't do this without you.
Needs more mounting holes, and the silkscreen can be rearranged a bit to use up some space, but it's routed and passes DRC. This version is more or less the same as rev 1, but adds a ROM cartridge port (mapped to 0x400000-0xBFFFFF, 8MB of address space without banking!) and the clock port, which provides 64 addresses of I/O space with a select line, plus bit-banged I2C pins to play with. Perfect for small add-ons like a wifi modem or a realtime clock. Fujinet, maybe? image
