Hi - i’m building all the Kosmo unit in lockdown but i have little electrical knowledge and can’t read the schematics confidently. currently finishing a couple of the 1145 VCLFO’S but the site jpegs aren’t very clear and i can’t see what wires go where. Can anyone take a pic of theirs for me? Free beers in return when you visit the Isle of Man! Cheers Phil ---

mine is not quite finished yet, but I can certainly help you anyway with schematic. What scheme did you use? (because there are several) and considering the title of the topic it is with the jack connections that you have some problems, what connections exactly please you make it with the PCB or on a stripboard ? ---

My rule of thumb on TruConnect 1/4 Style jack sockets is / - Slant = Ground, counter clockwise, skip 1 and the next is the Tip 🙂 basically on the “above” flatside, or 12 o clock. so 12 oclock being the Top and the TIP , and 5 oclock being the Slant and the GROUND ---

I usually just visually identify ground (the sleeve) and the outermost pin depending on which style jack I have. Learn what the switch pins look like and ignore those. The inner pin is for TRS stereo cables ---

The closed frame ones there are different ( slightly ) to the various ones I have (like Sams). I could not find a diagram when I looked quickly last month) All mine have switched connections for the Tip and Sheild, these are represented as (bold is the ones we want) **T** TN ( Normal ) S SN ( Normal ) **G** Which match with the scematic components in KiCad. ---

A friend of mine pointed me to a site that details pinouts for various connectors (old and not so old): [https://pinouts.ru](https://pinouts.ru) This site does its name credit. ---

There is no standard pinout for jack sockets, so a photo of someone else’s wiring may not tell you much. Safest approach is to use a cable and your multimeter’s continuity tester, as outlined in this thread: > [@HELP! Beginner Question CEM3340 VCO](https://lookmumnocomputer.discourse.group/t/help-beginner-question-cem3340-vco/444/2): > > Depends on the jack. The extra pin is probably a switch but there are many configurations (see [this post](https://lookmumnocomputer.discourse.group/t/can-i-add-1-4-jacks-to-this-eurorack-module/371/6) for some examples, and the linked document there for many more) and no standard pinout even if you’ve identified the jack type. Do you have a datasheet for the jack you’re using? Otherwise, plug in a cable and use your multimeter’s continuity tester to figure out what’s connected to what pin. ---
