savethecheerleader Posted February 14, 2012 Report Share Posted February 14, 2012 (edited) For the past couple weeks, I've been doing a lot of research trying to figure out what parts I need for my I posted about a couple weeks ago. I know that I will order a lot of stuff from midibox-shop.com, but something I'm having a tough time figuring out is what encoders to use. From my research, I see that the ALPS or Bourns encoders are the ones to get (midibox-shop even sells one). However, since I'm in the United States, I've noticed that any of the knobs I've found fit only 6.35mm or 1/4" shafts. Because of this reason, I thought it'd be a good idea to find encoders with 6.35mm or 1/4" shafts to make things simple. I've been searching into the depths of the Mouser and Digi-Key catalog and I can't find a 1/4" shaft encoder that would work for a Midibox project. Maybe I'm completely stupid, but I've been at this for the last couple weeks and I'm hitting a bit of a wall, so I wondered if you knew of any good encoders that work for the midibox project with a 6.35mm 1/4" shaft? EDIT: I realized from a notes document I made I did have this encoder down as a possibility for a 1/4" shaft but I wasn't sure if it would be compatible for the Midibox project: http://search.digikey.com/us/en/products/288T232R161A1/CT3001-ND/203826 Edited February 14, 2012 by savethecheerleader Quote Link to comment Share on other sites More sharing options...
jojjelito Posted February 14, 2012 Report Share Posted February 14, 2012 There are options in the code so that several signaling schemes fit. As long as it's a quadrature encoder chances are it will work. If you find something that outputs some odd Gray code you're off to coding land... Did you notice the Eagle Plastic 450-BA600? It will fit more common encoder with 6mm D-shaft and has no line. Mouser has several choices of 450-BAxxx knobs that will fit both 6mm serrated T-18 and D shafts. You'll save money on the encoders plus get to use more standard parts. Quote Link to comment Share on other sites More sharing options...
savethecheerleader Posted February 18, 2012 Author Report Share Posted February 18, 2012 Thanks so much again for your help. This was very helpful to me. I had completely missed the Eagle Plastic knobs. I ended up putting in an order yesterday. I ordered those knobs as well as some with a white indicator for the pots. I also ordered some 450-4760 knobs to try them out. For my encoders, I ended up getting a couple to try out. I got the Bourns encoders from the Midibox Shop and then I am going to try the PEC16-4220F-N0024 encoder. For my pots, I'm going to try the Alpha RV120F-10-15F-B10K pot as well as the ALPS RK09L114001T pot. I figured I'd try a couple to see what I like. I also wanted to try a 20mm shaft version of the pots and encoders because I think I might need the extra space. I'm thinking I'm going to end up making an enclosure from Ponoko similar to the sammichSID and those acrylic panels are 3mm. Quote Link to comment Share on other sites More sharing options...
