My build progress

@fredrik @Bitnik I purchased this. It was recommended by (Emile Gillette from MI):

I’m trying to program a Mutable Instruments Grids that has a ATMega328P via ISP. I have no problem programming STM chips but these are, for me, a bit more challenging and less straightforward. All of the documentation that I am finding is actually using an Arduino as an AVR programmer. Is there a direct way to program these or do you have to go through an Arduino? Recommendations on how to do this?

thanks!

IIRC you select your programmer in Tools->Programmers, and upload the code using File->Upload with Programmer.
Maybe, for some programmers, you have to select the correct serial port in Tools->Serial Port
Can’t check the exact locations of these options right now, but they are somewhere in the menus…

Progress on case #2

I’ve actually had a lot more luck doing that than using my actual ISP’s lately. I can never remember which settings to use with my cheap ebay special ISP’s but I always have a spare arduino laying around I can quickly flash the ISP software to and use.

Finished my Waveslicer:

Surprisingly quick and easy build. It’s pretty great. Here are a couple of before and afters:

With the right capacitor, this sub oscillator works great!

I’m one for three today. I wasn’t able to finish up the dual quantizer due to some code difficulties (and maybe wiring, but I haven’t tested that yet). I started the gate grinder. Just about done, but need to order a few more components and the button. I also built out a DIY version of the rat pedal. Here’s what it sounds like:

And I’ll use an on on switch on the panel so there isn’t a stutter when bypassing. I am just waiting on a voltage regulator to get from 12V to 9V and then it will be ready for a panel.

Fixed a small solder bridge / cold solder join on my clock divider that was messing with the 1/8 division (had me confused, it was working last night…then this morning suddenly no live on 1/8 - but there was still a weak signal on the jack. Saw a possible solder bridge on it and after a quick reflow it’s behaving well again.)

And got my 1222 mostly built:

Only mostly because I missed that it uses 3mm led’s and I only have 5mm on hand…and I managed to order common anode 7 segment displays instead of common cathode. (or is it the other way…I forget…whichever it uses I only had the opposite.)

So, no tuner yet…but otherwise it seems to work.

Confirmed it works but haven’t tried to tune it yet since I still don’t have a 1v/oct output from anything until I get some boards that should be here tomorrow to get CV outs on my Midibox sequencer.

plz witch schem have you test for this Sub ?

Which clock divider schem did you make? Sorry if I missed it if you discussed earlier. I made the fonik design and still have a problem after two reprints

It’s the one from Niklas Ronnberg here: http://familjenronnberg.se/~niklas/diy/eurorack/divider/

I just added the 1/64 and 1/128 dividers by repeated the output circuit on pins 3 and 4. My stripboard layout and full details are in this post: My first DIY modules - starting a Kosmo format build - #122 by juggle

@Dud ,right, I built that too, it was originally intended for the Behringer Crave

@heckseven do you have a schematic, or even better a stripboard layout for it, I really want to recreate it

I don’t have a schematic for this one. I got it via Pusherman and this is the BOM for it.

I do see some schematics around, though. One might line up.

This is my actual Progress… This is partly for m y own memory…

I got my second oscillator running!

When in doubt, reflow.

Rob,

If you decide to sell boards or release files to us for your PSU that would be wonderful. If it’s the latter I hope the files are put up in the easiest way because I’ll probably have order my own from a PCB house and I’ve no idea what I’m doing.
