The 10mm plate is NOT to protect it from direct shot. Only for debris.
If you directly shot your chrony, then you deserve to pay for a new one

I wonder how much armour I'd need to use for my M1A with AP rounds to protect a Chrony.

D,
The best idea is not to shoot the darn thing. But, do get yourself a untit with the guts on the bench, just in case.

It wasn't damaged as bad as I think.

I have two questions about componetns located at PCB of Shooting Chrony Betta.
What marking has chip located at right bottom corner of PCB ?
What marking has capacitor located near this chip (top left corner of chip) ?

Welcome.
The chip as far as I remember is an EEPROM from Microchip, I think it is an I2C variant.
The blue capacitor is a standard decoupling, 100nF for it.
IMO, you do not need this EEPROM if you are not using it for shot memory,
OTOH if the uC pinsg and waits for it to respond, it may hang the system altogether.
If you do need it, IMO, any I2C EEPROM from Microchip would do since it usually have the same pinout.

Can you lookup at exact marking ? Memory capacity is still unknown.

Marking is 104 (10 * 10000 pF).

EEPROM can be used as storage for device configuration.

I have to find time to dismantle mine, will post a better image once I do.

It could be, but I sincerely doubt it.
Short of taping the I/O to watch the traffic, I wouldn't know exactly.
Good luck mate, please post your findings so others could benefit.

Gelan...you are the electronic wizard here mate...would the cost of building a chrono be more than buying a similar unit ready to go? |
One off electronics are expensive as as buying a Holland & Holland Rifle.
At the 50-100 quantity it becomes more reasonable, at 1000 it becomes commercially viable like one of those Turkish double barrelled rifles.

Grey ghost,
That chip that you have circledat the bottom right looks like it could be a 555 timer chip, but the one that is broken looks like an eprom.
I could be wrong there are other 8 pin ICs out there.
