From the TriggerTrap site:
It’s bloody annoying, because we thought they were finished already and ready to ship, but when we were doing our last round of checks, we discovered something rather awkward we found a last-minute component fail (the capacitors supplied by the factory for our prototype were the wrong size and shape, because they replaced the parts we specified with different parts).
We need to source and replace the mis-ordered parts with different ones, but we’ll try to make sure this happens quickly, and we’ll keep you posted separately, promise!
