Verified Stripboard Layouts!

Who’s got them, built them, and know they work?!
I did this one a few weeks back. Works quite well.

Oh thats awesome! Do you know if it works properly at +/-12v, as the diagram lists a +/-15v supply

Most 15V designs work on 12V, though sometimes minor adjustment of some components is needed to make them run as originally intended.

Apparently the CEM3340 can only take 24V peak-to-peak anyway, so using a 15V supply doesn’t really get you anywhere.

That’s all well and good, but I was referring to the stripboard layout of the 808 kick :wink: Specifically whether Doolang had tried it on a 12v supply and if it needs adjusting to make it work properly.

Yup! I’m using it with a 12volt supply. No issues. I find the output a little low. Trying to remedy that right now.

Fab! I have about 90% of the components for it and am putting in a rapid order later this week so I will have to put one together. Have you got any of the other 808 layouts? Just being greedy now :stuck_out_tongue:

Check this place out. I haven’t tried them myself, but people have had luck with them.

Here’s my TR-808 Bass Drum. I added another op-anp to boost the output.

Just have one more tweak to make and I’ll post a video

Hey so I just finished building the strip board version of the vco tuner. It seems to be functioning for the most part but the display seems to be spouting random lines and values and everything seems to be wired correctly and done correctly. I’m not sure if anyone else has built it and encountered a similar issue with the display not working or being accurate. The most I can get are random F,G,ds and maybe an occasional B. please help?

This thread may be useful for running specific designs on different voltages, from Muffwiggler. Apologies if linking to other forums breaks some rule.

I had the same issue. Edited some code and it’s fine now. Try this. New Tuner Sketch

Check yo pins. That seems to be a common mistake if its throwing garbage.
