Frequently Asked Questions

Do you sell the other parts like the fake dynamite?

No. The Game Timer Pro only includes the electronics. You build your own fake device to put it on. For example, you can make fake dynamite by covering wood dowels with brown paper.

Can the Game Timer Pro be powered by batteries?

Yes. Six AA, C or D cell batteries can wired in series to provide 9V. C or D cells will provide the longest life (several days). A 9V battery will only last a few hours. You can also connect a LiPo battery pack with 7.4V or 11.1V. The device draws about 90mA of current.

The device “detonates” immediately after I press the red button — why?

You probably did not connect the wires. The default configuration is to choose a random detonation wire. If you did not connect any wires, then the device thinks that you cut the detonation wire immediately. Either connect the wires between the left and right sets of terminals, or set the “dEt” configuration item to “nonE”.

What are the dimensions of the Game Timer Pro circuit board?

The board is 3.3 inches (84mm) wide and 2.8 inches (71mm) high. The mounting holes are 1/8″ (3.175mm) from the edges of the board and are 1/8″ in diameter.

Do I need to replace the wires every time I cut them to defuse it?

No, if you don’t want to constantly replace wires, you can simply pull the wires out of the screw terminals. You need to leave the screws loose enough to pull the wire out, but tight enough to make an electrical connection.

Does it matter how the 4 wires are connected to the device?

No, as long as the 4 terminal connections on the left side are connected to the 4 terminal connections on the right side, the order does not matter. All the connections on the left side are the same — they are connected to ground.

Can I modify the source code?

Sure, the Game Timer Pro is open source software and is available on GitHub. The Game Timer Pro is essentially an Arduino and you can upload new code using a USB to serial adapter.

How accurate is the clock?

It is fairly accurate, but may gain or lose up to a few seconds per day. It is accurate enough to serve as an everyday clock, but is not a precision timepiece.

Can the Game Timer Pro be used to build a real explosive device?

It is no more dangerous than any ordinary alarm clock. Of course, someone with advanced knowledge can always build something dangerous, but this product is not going to enable that more than a regular alarm clock would.

Should I make a fake bomb and bring it to school or work to show my friends?

NO, are you crazy? It’s possible to make very authentic looking device, which means it’s possible to scare people and make law enforcement take it seriously. DON’T scare people with such a device, leave it unattended in public, mail it to someone, or take it to the airport.
