Ray,
Just another hello from 71 year old in the town of George in South Africa. Thou not near you but still.
I just moved from the PIC Basic Pro environment to AVR/Arduino world after motivation from a youngster.
Good move experience so far.
I have just successfully created a stepper driving circuit for a belt feeding system in a bottle filling factory.
To be commissioned in 2 weeks time.
I must admit I got a lot of information from the forum and especially from Nick Gammon's sketches.
I am still planning to write a ballistic chronograph sketch. The LED/photo transistor sensor and amplifier has been tested on my oscilloscope and seems to give a nice pulse when bullet passes the sensors.
Another project that I am planning to build is a digital readout for my metal lathe, indicating movement to a 0.01 mm accuracy. Do not know if that accuracy is possible. I am looking at using 2 rotary encoders with an LCD display each for the 2 axes.
I hope you the talk helped a bit.
Please feel free to make contact. I will be happy to share my Arduino experience so far.
Danie.
