SammichedSince2010

i replaced the encoder today, now everything is working like it should. so my problem is now officially: [solved] thanks once more to wilba and nils for helping me out with a replacement! [edited for typos]

my noob-to-noob advice: get wilba's excellent sammichSID kit! it's well documented and comes complete with all the necessary parts (excluding the sid chips - which he has run out of somewhere along the waiting list). i recently built one myself with only very little soldering experience. for a total noob, it's not exactly easy to build, but thanks to the good documentation, it's perfectly manageable. definitely much easier than building an mb-6582 (the one with the led matrix). the sammichSID box uses two sid chips for either stereo or up to six voice polyphony. it probably could be used with only one sid chip inserted, but why would you want to do that? as for the three rows of leds on the sammmich sid box: as mentioned by wilba in the sammichSID thread, they are there only for maximum bling. they seem to indicate the levels of the three voices of each sid chip - and generally look very pretty (as long as you don't use blue leds - which would look crappy, fry your retinas, and destroy your karma). to learn more about the midibox sid, it might not hurt to read the manual. ;) if you really have no soldering experience at all, i would strongly recommend reading a few soldering guides and practising a little before building the actual kit. you could start by desoldering and resoldering some parts from the mainboards of the two c64 you will source the sid chips from. :)

great, thanks!

apparently not. and neither do segor or reichelt. so i couldn't just replace it with that stec12e07 type they have at conrad? the only place i found that stec16b one is at a mailorder called distrelec. this would be the correct one, right?

thanks for the warm welcome! ok, so i'll start with exchanging the encoder and see if that solves the problem. would this be the correct part? ALPS ENCODER STEC12E07 (there's a conrad's right around the corner, so i could pick one up after work and exchange it this very evening) the encoder came with the kit, i don't know exactly what type it is. that bit about the problem occurring every 16 or so clicks was more like an estimate. i did indeed have the impression that there was some kind of regularity as to when the problem occurs, but when i started counting clicks, i didn't find a pattern...

hi everyone, as my first midibox project, i just built a sammichSID kit, and i'm absolutely loving it! great sounds, great little kit, thanks wilba (and nils, and tk obviously)! everything seems to be working fine, except that i'm having a bit of trouble with the encoder - hope i can describe this properly in english: when turning it clockwise, the value that i'm trying to increase will occasionally 'skip a click' (i.e. remain unchanged while the encoder has passed one of those clicky detent things), or even decrease by 2 steps instead of increasing by 1. this seems to happen around every 16 clicks or so, and it only happens when turning it clockwise/increasing values. anti-clockwise/decreasing seems to work ok. any idea what might be wrong here? is it the encoder itself, or is it a bad connection somewhere? where do i start looking, and how? i don't really know much about electronics, so any help would be much appreciated.
