Thread 'Sproing Deluxe'How do I go about getting a BOM for this so I can order the appropriate components? Thanks!
I checked my notes, but I didn’t write it down. Maybe KE-10720? Definitely something from tayda.Thanks for posting the build report! The BOM doesn't list the specs for the LDR. Can I ask what you used?
From a search for "Sproing LDR" I came up with this:This is really helpful, thanks! I noticed that the Moonshot and Trembling Loon call for the GL5516 LDR, which has lower light resistance values than the LDRs on Tayda, so it's good to know you had success with one of these. Adjusting the gap might be a key to making this work, so that's a great tip!
I’m not familiar with that part. Were you able to find a data sheet for each? Any big differences in the specs?Do y'all think I could use P9203 LDR for this build? I have a couple spares from building a couple of Uni-vibes. A quick google comparing P9203 and KE-107020 came up with no results!
I'm curious on how you settled on the 5528 LDR. I have one of these on my bench, and I have 10 different LDRs (and a whole bunch of optocouplers) to chose from, but I don't know what value to use. I also noticed that you used a 5mm yellow LED, but I saw in @Robert 's BOM that he calls for a 3mm red LED. Are you happy with how it performs?Update! I just finished one Sproing Deluxe with the 5528 LDR from Tayda. Everything works! But I used the small B10K and B500K pots and don't love that they barely peek through the top of the enclosure. Has anyone tried replacing those with anything else?

I settled on the 5528 after scouring the forum for other people's experiences - I linked to the different threads a few posts back in this thread. I'm quite happy with the result! The difference in LED doesn't seem to cause any issues.I'm curious on how you settled on the 5528 LDR.
