This is my last build for this year :
The building is in accordance with the original drawings but with some modifications :
adding MAX3232 with a DB9 connector for burning the firmware
using a OPA4342 instead of AD8534
adding 78L12/79L12/78L33 to be compliant with +15/-15 supply
And the major change is the using for the display - and for fun - IV-17 Nixie tube from old CCCP.
The PCB on the top are driving tube without any firmware change.
The most difficult thing is to provide the high voltage supply (84V!) by a pump charge from 12V,
my design is is largely based on this schematic .
No time for moment to do a video demo, but will leave it with the MicroBrute forge their friendship…
Once again, thank you Olivier for your awesome designs!
wuuuut! Bootiful! Make me one
Saw this on Matrixsynth earlier. I want a Braids with tubes too.
A true fruit of open source.
It is a complete parallel hardware implementation, not just a re-skinned MI Eurorack module!
@nicoo: Can you share with us more details of your implementation - not the panel and utracool Nixies, but details of how you went about implementing the published Braids circuits?
I think I need to change my diaper.
;)) thanks for your comments
with Eagle is quite easy to change a schematic implementation :
rip-up/undraw all the wire
on the schematic replace jack and pot by header
change the package of all non-dip component
for the STM32 or the DAC, export the component to a library and create a new package with support’s footprint
check that all components are on the same layer
Lovely. We badly need some HD video of those nixie tubes though.
This is so insane, it nearly makes me think about 5U….
stunning work @nicoo! i assume the tubes are really useful to warm up your apartment as well.
is it an ikea rack behind the microbrute?
