hi there
I found some nice trick for the rim trigger ... i attached Two small piezo of 10mm to 2 little metal L bar , mounted like the crossbar design to a free snare or tom lug with a simple screw ... place one at 8 o'clock and one at 5 o'clock , just where you hit ... The signal is more powerful than if you mount the piezo to the shell , mostly when it is wood...
Here are some pics ...
to make it you will need this....

the domino really helps to have a steady connection , it s also easier to exchange the trigger if needed....
dont put foam between the metal bar and the shell in order to have the strongest trigger signal ....
IMO it s better to place two of those guys for a DIY snare drum or tom ... the metal bar can be smaller or have a different shape , i just took what i had ...
