Yes! Those are the same ones @fredrik had me get and they work perfectly! I just didn’t know that there were different sized/types of pins when I initially ordered. I thought a socket was a socket. Lesson learned…one of many 🙂 Thanks for the Amazon link. I’ll hold onto that. ---

Are the two DIP sockets different from each other then? If not, I don’t know that you’ve gained anything with that configuration. ---

Yes, they are both different types of sockets. The one I soldered fits chips like the as3340 and tl072, etc… The Arduino doesn’t fit in this socket. The Arduino pins are more square and the soldered socket has round holes. The second socket that I got today that @fredrik recommended will fit perfectly on top of the soldered socket. The Arduino fits perfectly in this new socket too. So I can push all of the sockets together in that photo I posted and get my Arduino on the board that way. I just don’t know if by having the second socket in the middle will cause any signal issues. If this is an issue then I will need to desolder the one I initially soldered and replace it with the new socket I got today. I am just trying to avoid desoldering because I really messed up my LFO board by desoldering a socket I misplaced. I don’t even know if my LFO will work now so I don’t want to have that happen to this board too. ---

(I only recommend things I’ve tested myself, so this was just a “might work” 🙂 – but glad to hear it did, so now you can recommend it to others! 😃) Stacking them is a bit of a franken design, but I don’t see why it wouldn’t work if you get a good connection. If you feel adventurous and would rather desolder it, it’s easiest to just sacrifice the original socket – use side cutters to cut off the socket pins close to the PCB, and once you’ve gotten rid of the plastic bits, heat one joint at a time and push pin & solder out with some suitable tool (toothpicks work, see [here](https://lookmumnocomputer.discourse.group/t/1113-performance-filter/14/9)). But you can do that later, once you’ve finished the rest of the build and tested it. ---

Yeah, really no reason to desolder until you’ve tried the frankensolution! ---

Well if it’s a touring rig that would be one thing, but if you only ever use it in a home studio setting and aren’t doing time critical work then even if it does pop out, no harm-just be sure to put it in the right direction. (I burnt _ **4** _ ATTiny85s up in an hour a fortnight ago because I kept moving them from the programmer to the breadboard carelessly.) ---

I use breakaway female headers. Those closed ones always seem to shatter when I cut them. ---

Note to self…Frankensolution did not work. I have since desoldered and replaced with these. Only took 2 hours this time (compared to 3). I’m getting faster! lol ![20200326_233727](https://global.discourse-cdn.com/free1/uploads/lookmumnocomputer/original/2X/a/a534b2629af8fcd8a073d7f66773699f3e176e42.jpeg) ---

If you saw the rest of the board you would take back the “clean” comment…haha. My soldering skills still need some work. So far these headers have been the best solution. Easy to cut and no problem getting the Arduino in. ---

Naw, Nice work and your joints look great! That’s what human-soldering should look like. A bad joint would look like you tried to do it with superglue and a BB gun. The real question is: how is it working? How does it sound? ---

The link connector is a Share button by another name. Oops, I just realised you mean on the VCO. It’s supposed to be for easily controlling multiple VCOs. I don’t think the details of this have yet been published. ---

it’ll be on its way! if you check the schematic on the page you’ll see its connected to most of the inputs and outputs. on the to do list this week is to finish the design. basically its 2 modules that go with the oscillators. 1 oscillator driver which connects to the back of 1-3 oscillators to control its control voltage input with a built in simple lfo and portamento and also octave controls over all oscillators. then also there is a mixer module which basically connects to the same oscillators and goes on the other side as a shared mixed output. idea being you make up cables with the same stuff as the power ribbon cables to attach a bunch of the controls to the back of the oscillators. this oscillator driver/mixer set should be out I recon in a month or two, after the midi-cv and delay. and maybe the safety valve and a bunch of other. who knows! lets see what gets completed first! ---

(seems the main practical use for the link this far has been to [accidentally plug in the power connector there](https://lookmumnocomputer.discourse.group/t/1222-tuner-vco-module/16/58) and fry the opamps 🙃) ---
