Mongrol's MidiboxSEQv4 Build

Tips & Tricks

i was talking about the ALPS encoder . not the wheel rubbing or datawheel knob
in the WILBA design the datawheel encoder is the only soldered on the rear of  the PCB:

with ALPS stec 12 it’s difficult to mount it on the rear , bending the lateral fixation legs in a reverse way for soldering is not ideal .
that why on my SEQ i have mounted all encoder on the front of the PCB.

but if you solder the encoder on a little piece of perfboard (with lateral fixation legs straight/centered not externally bended ) and drill holes near each lateral fixation legs on the perfboard (distance between each holes equal distance of the two hole for fixation leg on the PCB)
you could attach/fix the encoder on the rear of PCB with two screw and nuts…so you win some space for the datawheel knob shaft…

sorry for my english , i don’t use the good words or syntax… oops

It’s clear – you need the threaded bushing in order to panel mount the datawheel encoder, in Wilba’s case mounted to the PCB. I forgot you were using STEC encoders. It’s no problem with voti or others. In this case Hawkeye’s suggesting of filing down the shaft is probably the easiest. With the perfboard idea, I think it might be a bit unstable n’est-ce pas?

Ok got it. My Alps STEC is front mounted on the PCB and is pretty solid there. I’ve looked and even if I widened the cutout to let the wheel through I’m not going to gain anything as the flat of the shaft is flush with the top face of the panel. So I’m just going to shorten the datawheel stem. Easiest solution.

yes i agree, easiest solution…
