You can’t overlay black onto the composite image. THe Video Experimenter can only increase the voltage to make white pixels, it can’t sink current to remove the pixels.
Here is an article that describes how to connect a relay so you can drive a siren:
https://nootropicdesign.com/projectlab/2014/10/28/using-a-relay-trigger-with-the-defusable-clock/Yes, if you choose pins that are not already being used, that could work. Which pins do you need? What kind of interface does the RTC have? SPI?
Were your devices ordered with any custom programming? If they have simpler Airsoft timer code on them (not a full alarm clock feature), then you can adjust the countdown duration by simply pressing the HOUR/MIN buttons.
Toolduino is a Processing application. .pde files are Processing sketches.
This Toolduino is very very old, so I’m not sure it works any more….
Just a switch connecting the pin to ground. The pins are configured to have a pullup resistor, so they measure HIGH when not activated, and LOW when connected to ground.
Yes, the DJ Shield pots are form a voltage divider between 5V and 0V, just as pots are typically used in Arduino projects. The Arduino reads the input with analogRead(pin).
The buttons on the DJ Shield and the two buttons on the Audio Hacker connect the Arduino input pins to ground when the buttons are pushed. digialRead(pin) returns HIGH when the button is not pushed, and LOW when it is pushed.
Yes, there are many example projects that mix signals together. See this one:
http://nootropicdesign.com/projectlab/2013/07/05/3-track-looper/There is an explanation of mixing signals. Also see the echo example:

Sounds like the device does work, but the programming is not working. There must be a soldering problem with the connector, or the 10K resistor, or the small cap next to the 10K resistor. I’d check the connections on those.
Yes, the usb to serial adapter should be visible on the Tools-> serial port menu. The error you are getting indicates that maybe you don’t have the right serial port selected.
What setting are you using for the board in the Arduino IDE?
Tools-> Board should be set to Uno.I don’t know when you bought your kit so if Uno doesn’t work, try Duemilanove.
I assure you that Hackvision is programmable using a USB to serial adapter.
A quick look at the LMH1980 makes me think it could work. I had not heard of this chip.
The V2 board is the new version and is what I’m selling now. It has the same layout as the original. I have not targeted the Due platform for my products since there are not that many people using the Due compared to the Uno.
