I'm hooking up a microphone to a laser. The laser changes intensity as the sound changes it's volume. I got the idea from the way laser record players work, and a fiber optic sound transmitter from a project in a Radio Shack project book.

Hello there! I'm planning to make an optic recording device and I need some sort of material or device that can read the light and make a hard copy of it so I can play it back. I would like to stay away from computer application programming at all costs. I am using a laser for the output device...
Hello everyone. I'm currently using FreeDOS for a project but I can't get it to automatically start to the second option on the boot selection screen. Is there any way to do this that doesn't involve going into the source code and changing it? Can I do it via the AUTOEXEC.BAT or CONFIG.SYS, or...
Hello Posters! I have recently purchased DR-DOS and was wondering how many GB it can format up to. I know it's probably not going to be much but I need to know. Please help!
I know of ways to configure the CD Rom drive for the Autoexec.bat and config.sys in MS-DOS is it the same way for DR-DOS? And how do you configure HIMEM.SYS? I've only used DOSBox for DOS. I need this to show that a computer can be made using old parts and sent to a poor community cheaply. As...

Hello everyone! I had what I think was a good idea and I want you to share your opinions on it. When I first read about how the Onlive service renders video games on servers I had an epiphany. What If you could render a whole OS realtime with the cloud. You could have a powerful multitasking OS...
I'm building a TV Typewriter from Don Lancaster's book "The TV Typewriter Cookbook." I know it's really old tech but it'd be nice to see where computer graphics all began. However since these chips are old and many of them obsolete I need help finding them. The book gives me multiple options of...
Maybe I could use one but I read the book again looking for the ROM setup, and found out there were pre programmed character ROM. can anyone tell me where to find this ROM chip: 6072 Character generator (7x9, Row scan, Uppercase and lower case) taken straight from the book.
Now I know this is really old school but I recently picked up the book TV Typewriter Cookbook By Don Lancaster. I was intrigued by this TV typewriter when I saw a picture of it on the Cover of Radio Electronics magazine. The parts of the TV Typewriter are still made today (like most chips)...
Hello everyone. I was wondering where I can get clear see through LCD Screens like the ones the pixel chicks used. I need it for a microcontroller project with my propeller chip and was wondering where I could buy one. any links or websites? Or do I have to get them custom manufacturer?
Could I use light sensative paper covered in fixer Between 2 dark plastic plates with a laser shining through it but using the laser first to etch it in without fixer?
Hello everyone, I'm new here so please be easy on me. I had an idea one day while working. What if you could use a certain optical disk to make analogue sounds? It would work like this: Every optical hobbyist knows that if you hook up a headphone jack to a laser and a sound source you can...
