It's been possible to make homemade PCBs for | decades. | | Even then, they could have at least used perfboard. | | No idea why someone would want to do it that way. That was | fine for the 1920s, but there's no excuse for such poor | construction these days. | aliswe wrote: | from the website: | | > Things have been made much easier by putting the most | complicated electronics on a PCB. | | maybe it looks like this nowadays? | | http://www.simandl.cz/stranky/elektro/ronja/ronja.htm | okl wrote: | To the contrary.

This is the project I pointed at when my friends | asked if you could do fast communications with visible light. | | The project has cataloged several installations | (http://ronja.twibright.com/installations.php) but I suspect | there's many more that haven't been registered. I'm curious if | any of these systems are still in place. ___________________________________________________________________ (page generated 2022-02-13 23:00 UTC)
