I've been studying the drawings and would like to offer some constructive feedback.

You don't show the depth and location of holes. For example, on the arduino base, you show a 5mm hole but not how deep it is or where it is located. On the sensor mount, you show location and size, but not depth (are they through holes?).

What is the purpose of the target face guides and the wedges you call "target face"?

This is a great start and look forward to making one fore myself.

For 50M here in New Zealand we use fan fold paper targets in a box holder (similar to a Gehmann) there are about 100 or so in the country designed and built by my clubmate Ross about 20 years ago, My club has 22 or so for a 20 lane range plus spares. They are driven off a car or truck battery depending on the range capacity as there is generally no mains power. These have proven to be robust / easy to set up as they are locked away in sheds etc. when not in use and relatively cheap to build at $300 NZ or so

what i would like to do is mount the sensor and control unit in these existing target holders. Again use a battery. If you want display monitors use a generator otherwise send it to a tablet.

For permanent ranges that have mains power send it a Raspberry Pi on each lane as a control PC for as each shooter they are cheap at $35 and broadcast it locally using WIFI throw in a small monitor. if you want a spectator display the RP can support 2 monitors.

I am sure in time someone would write a match control / results add on so we can run finals etc. / remove erroneous shots etc.

QUESTIONS
probably further down the track

1. how does it handle cross-fires? The suis Ascor (which I am certified for) the jury can discard the erroneous shot - rare in 10M common in 50M

2. and misses (ie strike the target box not the target)
A Sius Ascur indicates a strike outside the measuring area. Perhaps another sensor on the metal target face will pick up any strike that doesn't register?

I have been following your work since you first popped up, but something that I may have missed, you say above that you use standard target faces/paper? If there is no roll, what happens (after only a couple of shots) when a hole has been shot through the middle, and from then on there is no hit on the paper?

there is no provision at the moment for cross fire or box hit. the software would be easy to write. the electronic sensors...a bit more work :)

neither me or the electrical engineer have much experience with the commercial ESTs. can we contact you for technical details on Sius?

common question :)

the fact is that the sensors (microphones) pick up the sound wave of the pellet passing by, not the sound of the paper being ripped. the paper is there mostly for aiming purposes, providing a sound barrier and dispute management (in competitions).

so the system works without any paper.
the other issue is accuracy. testing on that is ongoing...
