15KHz generator: dtctr.

Post by ube » Mon Dec 03, 2018 10:36 pm

So here's my next little contraption to be sold at Exxos'; dtctr. Powered by a single cr2032 battery, runnig an ATmega328P at 16MHz it generates a 15KHz image at a press of a button (and waiting 5-6 seconds, the firmware is really slow). I'll be sending a batch of 20 to Exxos within a week (I'm waiting for some capacitors). This batch should be taken for what is it: proof of concept. The schematics and code can be subject to change at any time.

(Keep an eye on this topic, I'll be posting here when it's available in the store.)

Edit:
Forgot one of the cool things about it: since it's running at a 328P it's basically a Arduino Pro Mini and can (and is) programmed using the Arduino IDE and an ISP-programmer (or an Arduino as ISP). So developing better (faster) firmware ought be quite easy.

So: some glamour shots.

Wow, this is nice. So this could be used to feed a test signal to a 15 KHz CRT as well, right?

It would be really nice if the firmware would allow for displaying PAL/NTSC test patterns. See viewtopic.php?f=25&t=1402&p=14996&hilit=full#p14996

Haven't tried it. But if it's a RGB monitor it ought to work with an adapter for whatever input there is on the monitor.

I don't think urban is making another batch because there wasn't much interest in them.
