yeah just have to wait for some to arrive now probley next week now :(
dont have an oscilloscope my self but my local hackerspace does but there open night was tonight so might have to pop down next week if i need to.
I shall up date the thread once they have been changed out and some more...
ah ok thats all making a little more sense.
I have tried to keep the led in an encloses
Its designed to make sure the BB is in the middle and that the LED only has a small hole to see incomming light.
works fine dropping the BB through but once its shot it doesnt detect it and even the...
below are both the detectors i have tried and a BB for show.
both are maplin
Left is NP64U **broken link removed**
right is ch11m **broken link removed**
Maplin is rubbish on there info.
Might have to order something in via else where but at a loss as to what I even need now.
As you can see...
I might have to go back to the drawing board as this isnt working. ive wiered up as per the diagram and tried a few different ways all with no luck.
i have ran the signal in to an arduino as i thought this would work to keep the led on for longer and so i can see out put on a screen this works...
Thanks guys
Eric - There only seems to be a small amount of info on the site no data sheet and i cant see a response time.

Brian - ill add in the resistors and do a little more testing I had a 22k instead of a 10k (i started with 10k) as I found the BB would Trigger the...
Now I'm no electronic wizard so bear with me.
I have mad a small circuit designed to detect when a BB gun is firing and flash a small led on the side of the BB gun to let you know its firing (and still have ammo).
I used these RX and TX led's from maplin as a detection (CH11M, CH10L) the signal...
yeah should have thought of that one this is how i have it wired at the moment(i have tried a few other ways which didnt work)
the interrupter is just a phototransostor (**broken link removed**)
hope you able to help from this

ah i wasnt sure what you meant when you said...
Hi All
I have used a 74HCT14N for a circuit I have designed (not the best with electronics but learning) i was advised a 74HCT14N would do what i want but it does the opposite i have a photo interrupter that i want to turn an LED on when it is interrupted.
using the 74HCT14N when it recives a...
