IIRC, there's also an acceleration curve that has caused some users to think their encoder was busted.
-
Any updates on this? If we knew for sure that a final batch was happening, we could help put out some feelers into the deep dark reaches of the internet, get more people queued up.

Just thought I'd update this thread in case anyone else has these readings and is confused about them. Continued the build without issue, everything worked out fine!
-
Awesome! I was really concerned at first, but the more I read and the more I learned here, the more things sounded normal.
I'll get started on step 5 tonight, just as soon as I finish a visual inspection of the board like you said.

I'll post some of the actual values when I get home after work today, but they never settled enough to get a single reading. Basically, the resistance value would start out negative, rise toward zero steadily, and continue well into the positive numbers until it passed the maximum number for whatever mode the multimeter was in. I do remember that the 200ohm mode (smallest possible setting on my meter) was too small to be much use; it'd pass zero and go past 200ohns within a couple seconds.
With the multimeter in continuity mode, it would beep through all the negatives, right up to just past zero, then stop. I believe this is the expected behavior, yes?
Like I said, I'll post actual values when I get home. I also took some pictures of the circuit boards and the areas in question, but they don't want to upload from my phone, so I'll have to post those when I get home as well.

The resistance seems to be continuously increasing. I took a look at the circuit diagram and it looks like the non-ground pin on the voltage regulator is connected to a big capacitor. If I understand you correctly, that means the continuity and resistance readings I'm getting are correct, right?
I'm not 100% confident in my soldering skills, but I'm even less confident in my electronics knowledge. I spent some time soldering a few years back, but it was all circuit-bending, so troubleshooting wasn't really part of the M.O. I just want to make sure everything's ok before I move further on this project. :)

I was just finishing up step 4 in the sammichSID assembly instructions and I'm running into a problem I want to fix before I get any further. On step 4.19, I am to check for shorts between all the voltage regulator pads. Everything seems to check out except the middle pin of my 7809 (should be ground) and the pin closest to the edge of the PCB.
For some reason this connection is giving intermittent beeps when I test for continuity with my multimeter. I can't seem to reproduce it consistently, and 95% of the time it's fine, but that little beep every once in awhile has me worried enough to pause.
My soldering skills are beginner, but there's no visible mistake I can see. No obvious shorts, the joints look OK.... Could I have fried a component somehow?....would that even cause a short?
Checking some surrounding joints, I'm actually getting the same issue with the next nearest joint as well, one of the leads of C9.
Ivette Reid redoing each of these joints with no change.... I'm afraid of doing more harm than good at this point; frying something trying to fix a joint that might not even be bad.
Any ideas?

What's the status here? Both this thread and the wiki page seem to drop off suddenly. It doesn't sound like there was ever a batch #4? Will there ever be? Are all the kits gone?
-
Did you figure out what was wrong with the SID?
-
Is this still for sale, or....?

Located in USA, willing to deal worldwide.
Ideally, you want to trade your SID synth for something I already have. I don't have a lot of spare cash, but I got plenty of gear I'm not using much. That said, if we can come to an agreement on price/shipping and you don't mind waiting a short while, I will throw something on eBay to fund a sale.
I have for trade:
- Arturia Minibrute
- KMI QuNeo
- Monotron and Monotron Delay
- Casio SK-1, SK-8, SK-60
Not interested in selling any of those (except the QuNeo), trades only.
I'm looking for basically any kind of SID synth. Unassembled kits are fine.

need information to start a sammichSID
in MIDIbox SID

Unfortunately, the sammichSID was a limited-run kit. All the sammichSIDs that were made have been sold and as far as I know, there are no plans to produce any more (although you never know)... If you already have your SID chips and want to build a synthesizer, you're probably going to have to go the modular route. It's a little daunting, but not impossible.
