Replacing batteries / Fixing a loose battery compartment


So, it turns out that some of the Triggertrap v1 models have a bit of a manufacturing foible: On some Triggertrap v1's, the battery compartment is a bit loose, which means that the batteries can rattle inside the casing. It doesn't usually cause any harm, as the solder points should be strong enough to withstand the strain, but if you are of the not-taking-any-chances persuasion, there's a pretty easy fix that makes sure your battery compartment is fixed solidly in place. As with so many other things, the solution is Sugru.

You will need:

  • Philips head screw driver
  • Some fresh batteries - 3x AA batteries. You can use 1.5v alkaline batteries, or 1.2v rechargeable batteries.
  • A package of Sugru

Opening your Triggertrap v1

 Step 1: Grab your Triggertrap

Step 2: Use the screw driver to remove the 4 screws and the top casing comes off easily.

Step 3: Carefully remove the touch-sensitive buttons by pulling the top PCB directly toward you, straight up. Be careful not to bend any of the pins connecting the bottom and top PCBs.

If you are replacing the batteries, skip to step 11.

If you are looking to secure the battery compartment, continue to step 4.

'Nailing down' your battery compartment

Step 4: Repeat the procedure with the screws on the bottom of the Triggertrap. Do note that the screws are not identical (the bottom screws are slightly longer), so make sure you keep them separate!

Step 5: Use a small amount of Sugru - slightly larger than the size of one of the spacing bars is perfect (this is about 1 gram of Sugru - so about a fifth of the amount you get in a standard package)

Step 6: Carefully create a small gap between the battery compartment and the PCB with your finger. You shouldn't have to force it, and you only need a couple of millimeters - like in the picture above! Note that there are some minor differences between the various Triggertraps, so some might move more, others less.

Step 7: Drop the small 'sausage' of Sugru into the gap between the battery compartment and the PCB. It's not an exact science, but try to get it about 1/3 of the way down the gap for optimum performance

Step 8: Place your Triggertrap on a flat surface, and press down gently on the inside of the battery compartment. You should feel the Sugru 'flow out' and flatten slightly - and that's precisely what you want!

Step 9: Place the bottom casing of the Triggertrap, and place the screws through the bottom of the casing. Then, place the little white or semi-translucent spacing rings over the screws.

Step 10: Place the bottom PCB back on the screws. Note that the bottom acrylic casing isn't symmetrical, so at this point, make sure that the curved edge of the bottom casing is towards the top of the Triggertrap. Next, replace the spacers onto the screws.

Step 11: Place the two outside batteries in the battery compartment first.

Step 12: ... Then add the third battery in the middle.

Step 13: Add the top touch screen board back onto the Triggertrap. Be careful not to bend any of the pins, and ensure that all the pins align with the sockets!

Step 14: Finally, place the top casing back on the Triggertrap, and replace the screws.

Job done!
