For Sale Wireless Rangefinder Servos

Darth Voorhees - Chin Cup


Wireless Servo Kit, with accurate button options.
Now with a more compact gauntlet module!
Updated November 2018


This kit comes with two circuit boards with a button attached to one and a servo to the other. The boards communicate with each other via a small 433MHz chip. When the button is pressed the servo turns 90 degrees up or down depending on the current state.

The helmet part is powered by 3 AA batteries.
The gauntlet part is also powered by 3 AA batteries. A new and revised layout also allows the device to lay flat.

This kit will require some engineering to fit into your helmet. I will supply you with enough materials that it should be easier, but don’t expect a plug and play experience.
There will be 6 servo mounts of various shapes included to aid in the mounting process.
A magnetic ear cap is also highly recommended.

Included in the kit:
  • Low profile servo
  • Transmitter module assembled on a custom circuit board housed in heat shrink
  • Receiver module assembled on a custom circuit board housed in a 3d printed box
  • Servo shaft extender (x2)
  • Servo mounts
>> Extra dummy buttons available for purchase on my website <<

Approximate dimensions: (D x W x H in millimeters)
Servo: (56mm x 23mm x 25mm) This measurement includes the mounting brackets on the side and does not include the gear head. The servo will extent about 27-30mm from your helmet on the inside. I have a large head and an animefan helmet. My head barley fits as it and I still can use the servo no problem.
Receiver Box: (57mm x 36mm x 22mm)
Receiver Battery Pack: (69mm x 49mm x 19mm)
Transmitter: (70mm x 25mm x 12mm)
Transmitter Battery Pack: (69mm x 49mm x 19mm)

Button information:
  • Alco Switch
    This is an accurate alco switch used on the right/whipcord gauntlet in ESB/ROTJ/SE.
  • Push Button
    This is an accurate push button used on the ROTJ/SE flame thrower gauntlet.
  • Glove Button
    This is a rubber nubbed button that can be attached to your glove and pressed more inconspicuously. The wire has a quick disconnect at the wrist to make it a little easier to kit up.
    I Velcro my button to a compression glove under my normal gloves. It adds a little bump, but nothing noticeable to the average person. I am able to either trigger the button with my thumb or by hitting it against my blaster.

Version 5 Improvements
  • Flat transmitter module
  • More compact receiver box
  • External, adjustable antennas
  • Power light indicator for receiver box
I am currently working on some other things including range finder lights, ability to use button cell batteries, and other things. When these are complete, I can work out a system to upgrade old kits if someone is interested.

Currently one left in stock. After this one goes I'll have to order more boards and parts so shipping time will be a few weeks.
