OK but how to mount them?
EDIT:
I managed to get the coil working at about 500 Apk OCD, thanks to Hydron for some tips on IRC
I had some problems with the precharge relay after removing 2:1 step-down transformer (powering from 240 V AC) The relay board jammed the arduino from booting and then some traces blew up
Relays I disabled the precharger and I'll try to figure out what happened when I receive a new board
Increasing on-time makes almost 2 m streamers but trips the OCD, I'll try detuning the coil a bit more How much can I push the CM200DY-24NF?
It took me a whole afternoon to get the MIDI interrupter working, so anyone using the code from oneTesla; to run directly from USB I did the following (tested on Debian but should work on win):
in oneTesla source change MIDI boud rate to 38400 install
ttymidi -s /dev/ttyUSBxxx -b 38400 &
Using aconnect connect Midi Through port to ttymidi port (to get output list: aconnect -o) aconnect xx:xx xx:xx
To play (Midi Through port) aplaymidi midi_file.mid -p xx:xx

Thanks for the tip, I've lost my (unreliably anyway) USB->MIDI converter so will give this a go once I've got a coil running in the UK.

@Hydron I managed to get it working on win, using this as midi-serial converter
and this for the loopback interface
After relay board problem I continued using the other relay as precharge, disconnecting the discharge resistor. Arduino jammed again after some time and charge resistor burned out, so I finally decided to take a closer look at the relay board.
I failed to desolder relays so I ended up breaking them off the PCB. I found that the common pin of the relay is connected to the actuator which has a short lead going exactly between the coil leads. That lead is sharp and is touching 24 V trace. So when the soldermask gave out, 240 V AC was connected to 24 V trace - I don't know how the power supply and UD survived. I ordered another relay board but I won't be using it for sure, it's dangerously bad!
