The Paintball Gun (marker) :
For this project I chose to use the Icon-E Marker for a couple reasons. Most importantly it’s an electronic paintball gun. The system uses a solenoid to fire the gun. Secondly is the price for this marker. At about 110.00 each it’s a bargain for a fairly reliable gun that we will be cutting up. This doesn’t have to be the exclusive marker for this project. In principle any paintball gun that is electronic will work out well. This just happens to be what we used. A couple Tippmann A5’s would be fun to use as well but you will have some custom fab work to work with them.

RC Switches :
Team Delta offers some really neat specialty RC Relays that have battle hardened in the robot combat arena for some years. We used the RCE200(A) RC Switch they offer for about 22.00 for the main firing interface of this system. This little circuit allows both guns to fire at the same time with the addition of a secondary relay board. I highly recommend Team Deltas products and I have used them with great success for years.

Acrylic:
For this project we will be using .220 - .250 thick acrylic. Acrylic is ideal for this project due to its durability and ease of working with. Some acrylic bonding glue makes a very strong and structural piece. If you wanted to you could use wood, but it would likely need to be thicker to be as strong, and the joints become more difficult to make strong.

Bi-Pods:
For this project we will be using two bipods. This model is usually used in firearms. They are easy to mount and have extendable legs to allow you to place it on uneven terrain and raise and lower it for concealment.

Co2 Tanks :
For this project we used two co2 tanks to keep the look uniform with side mounting them. The original plan was for a single 20oz tank to be placed under the turret, but through trial and error in the desired final result we side mounted two 9oz tanks. Either scenario will work well depending on the arrangement of the bipods

Air Fittings :
To accommodate the desired outcome for our project we had to get a bunch of custom air fittings and plumb the turret. This is a tedious process but gives a very nice look to the turret. An alternative method of supplying air to the turret is to simply use two coiled remotes, but this can become a tangled mess easily. A complete list of parts will be at the end of this article.

Radio equipment:
For this project we are using a three channel Radio with a very long range. The futaba ss3 is a good radio due to its range and low price. While its possible this is not appropriate to use for ground use it still should be considered.

Wireless Camera (optional):
To add another wow feature to our system we chose to add a wireless camera to provide real-time video feedback of the turret. This is great for controlling pinch points from a range and also give a more realistic engineering class to scenario paintball as well. The camera is low cost and available from countless online retailers. It operates at 2.4 GHZ (the same as wireless internet access points) so extending its range with an antenna upgrade is very simple.

Misc Hardware:
For this project we will be using a lot of miscellaneous parts that I just didn’t want to include in a full list here… we have sprockets, axels, screws, bolts, switches, wires… etc… we will have a full list a the end of the article.

Relay Board:
The key to the firing control on this turret project is the relay board. This simple board provides a simple way for our RC switch to trigger both guns at the same time. The total cost to produce this board is about 6.00 and we will offer some kits and preassembled versions on the site soon.
