Works really well and tracks well.
16/08/17 I also bought (dirt cheap) a non-functioning VCO from a forum that I will fix (it was cheaper than the faceplate on its own! One of the transistors was soldered in the wrong orientation. A quick swap and it worked fine.
Looking at the schematic it looks really similar to the Doepfer a110-1 (it sounds really similar).
Great sound. They track well over four octaves and seem stable on long sessions. They also go very low so double up as LFOs.
Worked straight away at power up. Great envelope generator - may have to build another one !
25/10/18 I did build another one ! (Very painless and easy build - no issues).
Had a few issues with this build - one of the jacks was shorting a resistor (which was located underneath the jack !) One of the LFOs was giving a mix of both LFOs. Also the LED wouldnt light up - worked when I reversed it (although that meant inserting it on the PCB opposite to the polarity marked on the PCB !) All working now though.
Really nice sound - very vintage. Love it !
Really impressive module - quite deep and you can do an awful lot with it.
The x-y scope demonstrates the strange attractors. I tried using toner-transfer to make the front panels - needs a little practice!
Simple passive multiple. Bought the panel for £1.75 (!) from the pusherman group. I wired it as either 2x one-to-three or 1x one-to-seven (depending on whether the jack into the fifth socket is inserted or not).
I bought one board from amazingsynths.co.uk and one from the pusherman facebook group (much cheaper !). I wanted to check if there were any quality differences before soldering more complex boards. They both seemed equally good.
The silver panel is a Greyscale panel (bought secondhand from the muffwiggler board) and the black panel is from pusherman.
The boards were surprisingly easy to build. Initially neither worked. The purple board had a cold solder joint on one of the opamps. A quick reflow and it was working perfectly. The black board was a pain to debug. It needed lots of probing with an oscilloscope and multimeter and hours of poring over the schematic ! In the end one of the resistors in the filter cascading circuit was open circuit ! (I hadn't heated it much at all so I have no idea why it was dead). After swapping it out the filter worked perfectly.
The following photos show the build process (the oscilloscope is showing the VCA working correctly).
24/02/18 Ornament and Crime is a multipurpose module for generating CV. It only exists as a DIY module. It uses a more managable size SMT (0805). It is based on a Teensy 3.2 Arduino board and runs firmware inspired and adapted from multiple sources (quantiser, Turing Machine, various Mutable Instruments modules).
It was a fairly straight forward build and worked on power up. The image below shows the AD generator (Piques, adapted from the Peaks firmware) running in the oscilloscope trace.
09/01/19 I built another o_C
Easy build with no issues, other than the upper switch had an issue in that the upper connectors should have been in continuity but weren't so I just quickly jumpered them.
These were 0603 conversions of the original 0402 Mutable Instruments Veils module. PCBs and panels bought from the facebook group, Pusherman. These were quite tricky to build - 0603 SMT with tiny opamp packages. The PCB was quite compact! Surprisingly the first one worked first time after a few false starts due to potentiometer pins not making a good contact (when only pushed in, not soldered in order to test it). The second one was much more of a pain: a few cold solder joints around the opamps were quickly sorted. The real difficulty was tracing a bridge to the ground plane from one of the pads of a resistor (that shouldnt have been in contact with ground !)
The encoders I used send a reversed signal compared to the factory encoders (Bourns vs Panasonic), so I needed to modify the source code and recompile the firmware to enable the correct direction of the encoders. (The releavant file is drivers/encoder.h and four lines need changing).
Sounds amazing and surprisingly painless builds !
23/04/18 It's so good, I built another one! (Partly so I could set up drums easily).
Very straight dorward build. Power section had no problems. Flashed immediately within the Mutable dev environment. Fired up fine. The only issue was no audio. A quick trace with the oscilloscope showed signals going from the STM to the DAC but no onward audio. A quick look at the schematic and it showed pins 3 and 4 should be bridged. Tapping both with the scope probe produced audio. A closer inspection showed pin 4 to be slightly raised off the pcb and not making contact. A quick bend with the tweezers and a dab with the solder and it was up and running.
I have another board and panel to build another one at some point in the future!
The only issues with the builds was setting the zero offset in firmware. This is a hidden mode entered by pressing one button on boot up. I just could no enter it at all. I set up the debug client and server and peeked around in gdb. It all looked good, just wasn't registering the button. I think it was the debounce code not registering it. In the end I just set a breakpoint after the check and poked the right bit so that the check passed. Continuing on with the code meant I could easily calibrate both modules fine.
To calibrate using openocd, run the openocd/gdb code - in one window run the openocd debug server; in another window run the debug client. Set a breakpoint on or about line 74 in ui.cc. Do a reset and init ("monitor reset init"). Set the "calibrating_" variable to "true" after the check and then continue. The module will enter the calibration routine and for each channel, one pot controls coarse offset and the other controls fine offset.
28/05/18 A month later I built another one. I flashed this with a hacked version of Dead Man's Catch alternative firmware, modified to include the latest factory Peaks code, along with software calibration. I needed to use openocd again in order to calibrate the zero offset.
Very easy builds. No issues at all.
It's worth making a note for the future about flashing them.
I used an Olimex AVR-ISP-MkII. I had a real pain trying to get
it to work on a Mac with avrdude in the Mutable dev environment.
I tried it on a PC using Atmel Studio and it worked fine.
I know I had to change the firmware for it to work with avrdude
so I used Atmel Flip to do that which was straight forward. However
avrdude still wouldn't read it. I saw that some people had had problems
with avrdude 6 (used in the mutable dev environment), so I downloaded
the avrdude 5.9 sources, installed the dependencies (usblib, yacc, etc)
and compiled it. Hooray, it worked. Unfortunately avrdude 5 config file
didn't have the m88p config. So I copied it from the avrdude 6 config and
pasted it into the v5 config file. After that, it all worked trivially easily.
To flash using the dev environment then use make as usual but pass
the variable AVRDUDE with its location, eg
"make -f branches/makefile AVRDUDE=
27/12/18
Built another MI Branches - using up spare parts !
Quick and easy build with no issues.
This would have been a nice straight forward build if I hadn't decided
to try to program one late at night after going to the pub ! I think I bricked
one of the MCUs when programming it from Atmel studio (I decided it would be
a good idea to use this software for some reason !) I think I must have set the
wrong fuses. I tried reflowing the crystal (removed it to check for bridges/problems)
and it was fine. In the end (probably a bad beer-influenced decision) I removed the
MCU with hot air. This meant I needed to buy another one on my next Mouser order.
This time there were no issues programming it from the Mutable Dev Environment. There
were also no soldering issues and it worked first time.
06/01/19
Completed another Grids - I had all the spare parts apart from two opamps
so decided to build another Grids.
No issues with the build. Worked first time.
Flashed and built the firmware from within the Mutable Dev Environment.
Very painless and straight forward build.
Both were quite fiddly builds with all the passives and ICs quite close together.
However, they both worked perfectly first time with no errors.
Above photos: panels and pcbs, large pile of components, power section complete
and tested, STM32 MCU and associated decoupling caps installed and connecting the
STLink2 programmer, flashing the MCU, jacks and pots inserted but not soldered,
testing, completed.
Both worked perfectly first time, with no issues.
The above images show the: bare pcb and panel, the power section built, the microprocessor
soldered, flashing the microprocessor, finished soldering the surface mount components, testing
all the inputs and outputs before soldering the through hole components, and the completed module.
It was a surprisingly easy build with lots of space and it all worked first time on power
up with no issues. It sounds very nice !
Very quick and straight forward builds. One worked perfectly straight away. On the other one
the second and third channels weren't working initially. I had a couple of dry joints on two
opamps that was a pretty much instant fix. (Initially the iron wasn't heating the joints well -
the tip wasn't well-tinned and I think that was the problem with those op-amps).
Very useful modules - offset/attenuator/attenuverter/mixer.
I ordered an 0603 version of Ears with
matching panels from www.allpcb.com. (The factory Mutable Instruments version is 0402).
The images above show: the bare boards and panels, surface mount parts soldered, the completed module,
testing the gate output with external audio, testing the contact mic and finally the three modules completed.
Straight forward builds. I substituted 1n5819 diodes for PMEG2010AEBs as I didn't have any.
I had to stack two 0603 470n caps in parallel as I didn't have any 1uF caps of suitable voltage.
Would have worked first time if I wasn't such a numpty and used 6v "special" lm324 opamps instead
of general purpose ones !! (Who needs LEDs when ferrite beads glow so pretily). A quick hot air rework
and they were swapped out. They then worked fine with no issues.
22/10/18
I thought I'd build one more so I can have one on each channel of a four channel polyphonic voice:
Not much to say. Trivial builds. Makes things quieter !
27/09/18
I built another one. This had an error on the pcb. One
of the tracks from the input of channel 2 was shorted to the
pot of channel 4. I broke the track and jumpered it with a
cut off piece of a through hole passive.
Straight forward build with no issues. Images show: bare pcb and panel, power section built and tested,
MCU and associated components soldered, flashing the MCU, module completed apart from control hardware,
control hardware placed but not soldered, testing the module, the finished module.
15/12/18
Built another MI Warps.
Straight forward build with no issues (worked perfectly straight away). I
used the parasite alternative firmware for this module. The firmware
doesn't have the normalization probe calibration code, so I added this
to the parasite firmware, which works well.
The files can be found on my parasites github.
Images show: bare pcbs, 0402 resistor size, populated boards, testing and then the completed builds.
These modules use teeny, tiny 0402 surface mount parts (see photo above of a resistor with my manky thumb for reference !
I was quite nervous before starting these as they are very closely populated boards with tiny parts - the diodes are
really fiddly and very tricky to see the stripe which marks polarity. For these builds I still hand-soldered them with
a soldering iron and solder. I did consider using solder paste and reflowing with either skillet or hot air but decided
to stick with a soldering iron, which I'm glad I did.
Apart from the eye-strain, these were reasonably straight-forward builds in the end. All three had issues in testing:
the tl074 opamps all had dry joints on some of the legs (strangely the opa4171s were all ok). These
were pretty easy to sort out - just touching up the opamp legs. After that they worked fine.
Images show: bare pcbs, pcbs with the pile of parts, power section of the boards populated, MCU and
associated parts installed - front, MCU installed - rear, flashing the MCU, completed build -
front with no face plate, completed build - rear, completed build, calibration (more than 1/1000 cent accuracy in this image!).
Straight forward builds. Only one issue - on one of the modules the display didn't fire up initially (I had wondered if I had a questionable
short on the MCU but it looked ok visually so I had left it - it was on the display data pins of the MCU so I quickly reflowed that pin and
it worked perfectly straight afterwards. I had bought encoders that were reversed (compared to the factory modules) - intentionally as
that was what was available. I needed to make some changes to the source code to change the direction of the encoders which was trivial (and indeed
I had made those changes before startiung the build).
Images show: bare pcbs, power section populated, MCU and
associated parts installed, flashing the MCU, completed build - all surface mount parts placed,
completed build - all through hole parts placed as well as the led level metering sub-board,
testing the module, completed module.
Fiddly but straight forward build. The main hassle was cutting down the surface mount socket mount
to fit the sub-board assembly. The module worked first time with no remedial work needed.
Images show: bare pcbs, power section populated, MCU and
associated parts installed, flashing the MCU, completed build - all surface mount parts placed,
completed build - all through hole parts placed,
testing the module, completed module.
Pretty straight forward build. I had two issues: I missed a bridge on the DAC (that was simple to fix) but there
was an issue with the addition of the keyframes - the frame light stayed on a long time and seemed inconsistent.
I worked out it was a dry joint on the ADC pin of the frame pot. It took at least an hour to work out if it was
not working correctly and then what the problem was! After that it worked perfectly.
PCB and panel bought. However, looking at the schematic, there was an error. The output resistor
is included in the feedback loop, leading to the possibility of opamp oscillation in the presence
of a capacitive load (eg with long patch cables). For peace of mind, I decided not to build it and
used the parts to build two Links modules instead.
I came back to this (28th August 2018) and spent a few hours laying out a circuit and pcb based
directly on the buffered multiple part of Links (with normalled connections between groups). I
sent the pcb off to allpcb.com (a Chinese pcb manufacturer) and am awaiting 5 test boards. I have
enough parts to build three of them if I want.
On the first run of pcbs, I made a mistake in Eagle and didn't create vias to join the ground
planes front and rear, so needed to join up three islands of ground. Works perfectly when that is
done. (The image showing the module being tested with the oscilloscope has a 'Y' offset on the scope
to see both traces clearly - it's not a voltage offset !)
02/10/18
Built another two own-design buffered multiple.
I corrected the Eagle files and have bought some more test boards.
Modules work perfectly - very straight-forward builds.
The files can be found on my github.
Images show: bare pcbs, power section populated, MCU and
associated parts installed, flashing the MCU, completed build - all surface mount parts placed,
completed build - all through hole parts placed, testing the module, completed module.
Both worked immediately with no issues.
After testing one of them, I built the other two:
Worked perfectly first time.
To compile the firmware I needed to change the source code change as well as change to the avr-gcc flags to enable compatability
with latest avr toolchain.
Images show: bare pcbs, power section populated, MCU and
associated parts installed, flashing the MCU, completed build - all surface mount parts placed,
completed build - all through hole parts placed, testing the module, completed module.
Both worked immediately with no issues.
On the newer modules (plaits, stages, marbles so far as of Oct 2018) MI
ow use SWD to program the MCUs rather than jtag. I jumper the pins of
the STLink V2 to the SWD pins on the board. With the STLinkV2 pin 1
(target voltage) needs to be jumpered to pin 19 (3.3v *from* the
programmer. Here is how I wired the jumpers to flash marbles:
In order to calibrate the dac, edited the source code to output
1v and 3v. I then measured the 4 dac outputs for both 1v and 3v.
From knowing the dac scale and offset as well as the calculated dac code
to output a desired voltage I derived the scale and offset for each channel.
I then hard-coded this into the firmware.
To calibrate the adc, long-press the rate and spread buttons. Feed 1v into
rate input, press one of the two buttons, feed in 3v, press button, feed 1v
into spread cv, press button and then feed 3v into spread cv, press button and
the calibration is done.
No issues with the builds - both worked first time. It's an awesome module!
The calibration files and detailed instructions, along with the gerber files for the panel,
can be found on my marbles github.
12/01/19 Built another Marbles as I had all the parts spare.
No issues with the build - worked with no problems immediately.
No issues with the build - worked first time. Wishing I had built one ages ago!
Straight-forward builds, no issues, worked immediately with no problems.
30/11/18
completed the last of the four.
No issues with the build - worked fine first time.
I built my own panel (and didn't do a very neat job ! Trying toner transfer technique - I
think I need to try more glossy paper next time). Straight forward build. The only issue was me being a
numpty and installed the two power rail filtering electrolytics in reverse - bang!
First time I've installed electrolytics the wrong way and first time I've blown
up electrolytic caps! Other than that, it worked well!
Straight-forward builds. (Quite long and tedious though). No issues. Worked straight away with no problems.
Whilst I was working out how the firmware worked, I found the Easter Egg - a harmonic oscillator.
I couldn't believe no-one else had found it before ! It sounds really good and is easy to access -
just patch the two serial ports with a three pin plug. Multiple units can be chained. Needs
to be power-cycled to change modes.
I have changed the firmware to allow easy mode changing for a single module but not yet added
it for multiple modules in a chain.
The calibration files and instructions, along with the gerber files for the panel,
can be found on my stages github.
I bought 10 pcbs from www.pcbway.com and also ordered 10 panels from www.allpcb.com.
Boom!!! Simple build. Just needed to adjust the value of the pull-up resistor on the accent
to allow a nice "thump". Now responds nicely to low (eurorack levels) trigger voltage and low voltage
accent (with impedance of ~1k) as well as nice and loud when no accent plugged in.
I used a tl072 in the end (just used a jrc4558d initially as I had no spare tl072s at the time.
I'll probably build a couple more.
Straight-forward builds with no issues (just a lot of passives !) Both worked fine first time.
Straight-forward build with no issues - worked fine first time. The only issue was flashing - it was
a little different to most MI AVR builds. It used the PDI interface (rather than ICSP). It also
didn't need the fuses setting explicitly. (Worth noting that there are two revisions of the board
with different ADCs which require different versions of the firmware).
Painless build. No issues. Works really well - a lot better than I expected and a lot more usable than the
DSO138 I built a while ago.
(The green sticky tape is to hold the screen stable whilst building. In the
last photo the screen is crooked - it was straightened up before putting in the
rack !)
Easy build with no issues. Fantastically useful module - I didn't know how much
I needed one until I built it! Wish I'd built one ages ago.
I bought a number of parts from aliexpress - the jacks, switches and a cheap
jlink clone. I made a board to allow connection to the mini-jtag from either
20-pin or 4-pin (SWD), but in the end just used jumpers.
To flash the boards, I used the mutable dev environment and a cheap Chinese J-Link
clone from aliexpress. I used openocd with the following commands:
Overall, a pretty painless build. Lots of fun to play with!
06/01/19 Completed the second one:
Initially it didn't run straight away. On close inspection there was a dry joint on
the QFN MCU - it worked perfectly after touching it up with a soldering iron.
No issues with the builds - all three worked first time with no problems.
Straight-forward build. Working out how to set up the build environment and compile the code to target
the module was more involved though !
It's a straight-forward build, well-spaced out 0603 parts but there is a high part count
and the parts are pretty expensive - it's not a module to want to fail on ! The build had no
issues and worked perfectly straight away.
It's a really cool eurorack sequencer - very deep and impressive but still easy to use.
For more information, see Performer Sequencer.
When building it, it's worth using the test firmware to check all the functions are correct.
I had some issues on different power supplies (due to the slew rate of the rise of the power rails)
that meant the module wouldn't immediately boot - it
needed to be powered on and then off again. After trying firmware hacks to play with the brown out reset
and it not helping, I added a supervisor (mic803) to hold the stm32 in reset until the power was stable.
This fixed all my problems and was pretty trivial to add (along with a 100nF cap from GND to RST).
Straight-forward quick build with no issues.
I started this module months previously. It was the only module I hadn't been able
to get working correctly. I was getting high frequency oscillation at the opamps. The
switches (when off) left the opamp inputs floating so any stray noise in the system
caused oscillation. I had stupidly soldered all the parts so getting at it to sort it
out was a pain. I had put it aside to look at later. I found a bit of time
eventually to look at it properly. I ended up soldering the open poles of the switch to
ground via a 100k resistor along with some feedback caps in the opamp loops, as well
as adding decoupling caps from the rails to ground. This solved my problems nicely.
I ordered pcbs and panels the day the module was released. The parts came the
next week and I built them the same day.
I edited the pcb to move the Recom DC-DC converter onto the back of the
board as it is too high to fit on the front without a recess in the panel.
It needed shifting over as it was quite close to the edge of the board.
0402, straight-forward build. No issues or errors with the build.
I have calibrated them, similarly to Stages.
All the files, including the panel, pcb and calibration code can be
found on my Tides 2 github.
Straight forward build, 0805 parts. No errors or issues with the build.
To flash it, I compiled the latest version (5.1b2). I added the code to correctly display colours
on the Kingbright LEDs used in this build (which give different colours to the factory SMR). I also built
firmware to allow use of a 24 PPR encoder as well as a 12 PPR encoder.
I connected the pins as follows (see image above as well):
Then using openocd I used:
openocd -f interface/stlink-v2.cfg -f target/stm32f4x.cfg -c "program combo.hex verify reset exit"
No issues with the build and it works well!
I'd fancied a S&H based on Kinks for a while, similar to the buffered multiple I built, based on Links. So
I knocked one up in Eagle. I decided to convert it to 0603 and mount the parts on the back to make it easier to
diy and debug. It works well.
12/08/19 Built another one!
The files can be found on my Jinx github.
