I'm embarrassed to say I've populated two of these boards but haven't programmed them yet.

Is there any consensus on the best programmer to use? I have a stm32f4 discovery board sitting on a shelf, is it possible to use the st-link off of that?

i think you can - someones done it for braids, not sure if it'll do the stmf4's or not, but you could check that online if no one knows

Looks like it - https://geekilyinteresting.wordpress.co ... -debugger/

I'll give it a try and report back.

You can. Just treat it as an STLinkV2.

If you need to DIY a cable, i posted pinouts for one in one of these Mutable threads (the Braids one IIRC).

thanks, i'm using a motley collection of jumpers for my avrispmk2

Could anyone make a judgement regarding the easiest one of these to start with. I'm fairly new to the DIY game and only have experience with through hole boards, but after buying a peaks unit I'm really wanting more MI modules.

Branches is designed as a first smd board , though i'd try an smd training kit from eBay first

I've got a handful of Mutable Streams panels in stock on Thonk too now

adam · Post by **adam** » Tue Nov 10, 2015 6:33 am

those went quickly

Thonk Support · Post by **Thonk Support** » Tue Nov 10, 2015 6:48 am

some of them yup

Still have:

Streams
Branches
Sheep
Frames

will get more in the future too i'm sure

yeah

adam · Post by **adam** » Wed Nov 11, 2015 7:27 am

ordered a few more chips for the tester, should be ready to send out to people within a week

adam · Post by **adam** » Wed Nov 11, 2015 5:00 pm

turns out theres a postal strike tomorrow - everything sent today will take a day longer than normal to arrive, 2-3 days uk, 4-6 working days EU. 6-8 worldwide

Do you mean an M9 thread? No I don't think so.

The 9mm pots that I sell have an M7 thread (as pretty much 9mm pot out there have) and they fit fine.

Apart from the first run of Braids panels (prior to Feb 2015), the panels actually will accommodate pots with M9 threads (i.e. ALPS RK09L).

just had something delivered, the lady at the post office may have been misleading me about the strike, i'm should go and give her a piece of my mind

edit, seems it was yesterday afternoon - yesterdays packages will be delayed, todays will be fine

Hello adam, these look exciting, especially the tester, as I have just been using my case's power for testing, and it's full now.

I would like to buy 1 each of:

Module Tester PCB
Module Tester Chip
Tides PCB

Shipped all together (when the tester chip gets in). Im in Hawaii, in the US. Thank you!

Thanks

I am enjoying my seaview, orders placed yesterday or today will be sent on Monday

adam · Post by **adam** » Sun Nov 15, 2015 5:14 am

much as i enjoyed the seaside in winter (alright, mid autumn) i am now poised, like a coiled spring, ready to ship orders again

Just a heads-up to prospective buyers of the boards being advertised in this thread: Olivier Gillet, owner of and chief designer at Mutable Instruments, has just (as in, on 15th Nov 2015) released updated versions of the PCBs for quite a few of his designs. I haven't checked what the changes are for all of these, but they are almost certainly just tweaks, mostly related to removing the need for separate +5V power, but there may be some other improvements. For example, the changes to the Braids design also dispenses with the centre detent pots, and most importantly, uses one of the built-in ADC channel on the CPU chip for the FM input, so that when the FM input is used for other things, such as in META mode, the fine-tune knob will still work - that's a significant improvement. There have been no firmware updates released at the same time, so that all improvements are purely hardware-related.

The GitHub repository for all this is at https://github.com/pichenettes/eurorack

The modules with updated PCBs are:

Braids
Branches
Clouds
Edges
Links
Peaks
Ripples
Tides

I'll do a comparison of each of these with the previous version when I get a chance, but others may wish to do so before that, so they can make better informed purchasing decisions about the PCBs offered here, many of which may now be superseded, although of course, they will still perfectly functional - all the MI firmware is backwardly compatible with earlier hardware iterations of the same module.

adam · Post by **adam** » Mon Nov 16, 2015 5:18 am

very noble of you tim

most of these revisions are the changeover to the PJ-301-M-12 jack i think - i may get some links pcb's made now that parts are easier for people to source

bennelong.bicyclist · Post by **bennelong.bicyclist** » Mon Nov 16, 2015 3:42 pm

No, the changes appear to be more extensive than just changing the type of jack sockets used. The changes to Braids, which result in functional improvements, I've noted above.

The change to Clouds from v0.2 to v0.3 appears to be the addition of a separate crystal to clock the WM8731 codec, instead of it being clocked by the MPU. Not sure what the effect of this change is, but presumably it results in a functional improvement - Olivier would not make a change that adds additional components to the design unless it actually improved things.

I'll examine the rest in due course. I suspect that there are more than just jack socket changes to Grids.
