arduino / Raspberry PI anyone good with this stuff?

This will be an interesting thread. I too am playing with a few arduino's, and definitely know that I have more to learn yet, than what I've accomplished. Still, there is hope. Others have made things that worked. ;)
 
The quick and easy way to think of their usage is as follows.
Arduino - better for hardware interaction components. i.e. sensors, LEDs, etc -lightweight coding for interfacing
PI - better for software driven solutions (i.e. mini computer) Coding will require knowing linux, python, etc.

For what your looking to build, I would think the Arduino would be a better fit.

Or a Pi with a breadboard connection to the arduino. Depends on how much logic op wants. I overclock mine and as such bough the little heat syncs. Mine runs stable at 1ghz. currently I am gathering hardware to turn mine into a voip phone system. i have another I am going to set up as a VPN access point. In any even you need to get familiar with linux. I was thinking you could do reactive targets the pop up and random intervals. Kinda spendy though but doable.

He's looking to build a cheaper target hit indicator system like isis. Since that's would be primarily sensor i/o activity I'm guessing arduino would easily work best.

I'm in agreement arduino would be better suited depending on what exactly you're planning on indicating and how you plan on getting that information back to the shooter. Fire me a PM. Ive got some experience on arduinos and this sounds interesting.
 
Another vote for arduino. That's what the kids learn and use on the FIRST Robotics competitions (FRC and FTC), so it is (apparently) not too difficult to learn. Usually the kids are up and running (with a s/w mentor) in a few weeks. I don't code anymore (not in years actually, and even then it was ugly), I handle the fabrication/machine shop for the kids. Even still, I over hear a lot of the learning issues with the arduinos, and they seem to be fairly straightforward, even for some complex processing (like the shooter mechanisms, geo-location sensors and IR sensors that are required for the autonomous mode of the competition).
 
You may need a faster processor than the Arduino for an electronic target system to get acceptable accuracy. I have spent a fair amount of time looking into the electronically scored target so LR shooting alone would not be as big a pain as it is. I have a prototype system built up that I need time to get out and test it. The mathematical solution is rather intense and I am not sure it can be fit onto an Arduino. For my prototype I went with an mbed board (mbed.org) to get greater speed and processing power.

I would be happy to try and answer questions you might have.

Hes not looking to "Score" Just flash a light when the target is hit.
 
When isis was mentioned I assumed it was a typo for SIUS which is the electronic target company that manufactures acoustic scoring targets, I guess I was wrong.

If all you need is a hit indicator go to arduino.cc and look up the ping example and that will need very little modification to be used as a hit indicator, but I think you will need to use something a little more substantial that paper as a target, maybe 1/4" plywood or masonite for the vibration of the bullet passing through the target propagates to the piezo element.

I would be happy to answer questions that you have about this topic either by PM or in this forum. I sometimes go awhile between my 'Hide visits so do not think I am ignoring you I have probably not been around for awhile.

I was going to a Arduino or beagle bone. I was going to use the sensors like what is used for car alarm seismic sensors. My other thought was a acoustical sensor that can detect super sonic projectiles. All the stuff I haven't had any time for.
 
I've played around making a hit indicator using an arduino, vibration sensor, buck boost and leds. Worked alright until it took too many hits and the vibration sensor went kaput. Was just playing around with it for fun so didn't go any further. Programming side was easy, hookup was pretty easy, just finding something that would be able to handle repeated hits is the only real issue (which is probably just a side effect of using cheap parts I had laying around).

*disclaimer* This post is scatter brained because I was brainstorming as i was typing.

You could use an esp8266 or esp 32 as your MCU for your sensor downrange and use the WiFi function to send the signal back to another MCU at your shooting position and have it light up a led or set off a buzzer when you get a hit. You can use dollar store cell phone power cell that has a usb port for power. For a sensor you could use a mpu-6050 gyro/accelerometer. whole setup would be less than 10 bucks if you order from aliexpress (they are the same stuff you buy in the US but without the markup) Depending on range you may want to look into an external antenna which will increase the price a little. You could also do a custom board on a free version of eagle if you wanted to get fancy. JLCPCB will make you 10 boards for 2 bucks (plus shipping). DHL shipping isn't cheap if you want it fast.

There are so many options on how to do the software, you could do a web server and directly connect to it and have it show a hit counter that can be reset, you could use a cheap camera module and actually see your hits. I think you have inspired me. I will be back and post what I come up with. Might be a while as I have little free time.
