You certainly can copy open source boards, but you are asking for help in the product support forum.
The diodes are needed. They are there for a reason. They keep the current from flowing between the two video output pins.
The Hackvision cannot output VGA. It generates a composite video signal. Are you trying to create a VGA signal? TVout will not do that.Of course you can make the countdown go down. Hold down the alarm button when pressing the MIN and HOUR buttons.

So, you are copying my work instead of buying my product, and now you are asking for help in my product support forum?
What version of Arduino are you using?
They made changes in the 1.5.x versions that broke a lot of code. Use version 1.0.x.Your link to board and schematic is broken.
Why did you substitute parts and “take out some of the extra things”???Uh, are you asking about the Video Experimenter? Sounds more like an Audio Hacker question. Please ask about that in the Audio Hacker forum.
You need to use the special Video Experimenter version of the TVout library. Where did you get TVout? If you cannot compile because the API entry points capture() and resume() are missing, that indicates you did not use the special version of TVout that I provide on the project page.
On the VE page: https://nootropicdesign.com/ve/
Download the library where it says “Download the enhanced TVout library here”
This is the direct link: https://nootropicdesign.com/ve/downloads/TVout-VE.zipMarko Marko,
Does your Hackvision have a Duemilanove bootloader? Any Hackvision sold in the last couple of years has an Uno bootloader.This is the correct TVout to use:
http://code.google.com/p/arduino-tvout/downloads/detail?name=TVoutBeta1.zipThis is documented on the Games page:
http://nootropicdesign.com/hackvision/games.htmlIf you have an Uno bootloader, I may have to provide a precompiled .hex file for Asteroids just as I did for Space Invaders/Pong. Something about having the Uno bootloader makes the older games not run when compiled with the newer IDEs.
PLEASE read the FAQ: http://nootropicdesign.com/audiohacker/faq.html
The Digit Shield library uses timer2, not timer1. The commented-out code is for timer1.
You can certainly try different timers in the Digit Shield library if it helps get around compatibilty issues with your servo. You won’t break the Digit Shield. ;DThe servo library uses timers and will interfere with any code that uses timers. The DigitShield code uses timers to control the refresh of the display. Many things in the Arduino world are not compatible with one another.
Are you familiar with how to control Arduino timers? If so, you could disable the Digit Shield display while you moved the servo, then turn it on again when the movement is done. Would that help?
scanLine should be the right variable. I’m not sure why you see it only go up to 7. That’s the one.
(based on my fuzzy memory of 4 years ago when I developed this product). I’m not the author of TVout, so I had to learn it just by looking at the code.
