batch 0: July 2012 aka “pioneers run”
Starting here myself :)
batch 0: 7 units
batch 1: 4 units
batch 2: 6 units
batch 2.5: 1 unit
Batch 2: 1 unit
batch 1: 1 unit
Batch 1 : one unit which is working great :-)
Batch 1: 1 unit
batch 2 – 1 unit
Batch 1: 1 unit (with SMR-4 board) working perfectly.
Also, one CEM3379 filter board which works fine except for the audio in. I broke the audio in by putting the bridge in the wrong place, and ruined the pad when I tried to desolder and move it. Nobody replied to my questions about ways to fix it, so I presume it’s not fixable. I understand the lack of instructions for the more “specialist” boards, and the BOM is enough to build the board, but I think perhaps there should be a brief mention of some of the “gotchas” and things to watch out for could be added to those pages.
batch 1: 1 unit, working great!
batch 1 : 1 unit, working fine.
Batch 1: 2 units CEM3379 and SMR4. They work well. I messed up a digital control board and had to get another. Desoldering is really tricky for the Audio and MIDI Jacks. FYI
Just ordered a ssm2044.
batch 1: 1 unit – works perfectly
batch 2: 2 units – heavily modified but works perfectly.
SSM2044 filter board: works perfectly with and awesome sound ! (BOM: you’ll need 4 Electrolytic cap, NP/audio grade 3.3u and not “3”)
Batch 0: 1 unit
Batch 0: 1 Unit
Batch 2.5: 1 Unit
Both without real problems.
Hi renardo,
can you send me the specs + schematics to your time machine?
Batch 2: 1 Unit assembled successfully
Self sourced, working good now after a couple hick-ups
batch 2: boards, LCD & chips (SMR4)
1 unit working fine!!!
but no case yet (of course)

@tanaisfox, that’s batch -1 or -2 :)
batch 1(?): 1, runs well after I realized I: had one ic socket reveresed, and one audio output capacitor backwards. clear plexi with a Canadian maple leaf.
and 1 shruti in a bamboo wedge
batch 3: 1 unit with CEM3379 filter and green PCBs. Soldered a cap of incorrect value.
Green?
yummie!
Batch 2 (2 it was, wan’t it?) got 2, built one, works fine, despite my continuous attempts at destroying components… :)
so for now 1:1 fine
Batch 3: 1 unit (SSM2044 filter, red PCBs). Swapped two resistors because I followed the online BOM/image while the circuit has changed a tiny bit.
still waiting on a digikey shipment :(
Batch 3: 2 unit (SMR4, black PCBs ; CEM3379, black PCBs). Discovered that red LEDs of same color/intensity can look totally different (from bright purple to invisible) behind a 6% reflective blue sheet of acryl. Had to desolder some of them and made a bit of a mess of the board, but it’s fine. Had to swap a resistor on the digital board because customer asked for a super-bright LCD.
Batch 2:
With correct firmware, works 100% with CEM3379 filter (not had a chance with the SRM4 yet)
ISP programming header did not work initially due to bad 595 (replaced and worked, was getting a resistance between pin 13 a +5 preventing it from programming)
to also add, building the bootloader and OS on a windows based AVR toolchain checks out (WinAVR)
Batch 3: 1 unit (stock configuration – black PCB, blue LCD, green and orange LEDs). For updating the assembly instructions. Had a 100W lamp on top of my head all the time and it really shows how bad I am at soldering.
