Hi everyone,
I am new to electronics and new to the forum.
I am wanting to develop a device similar to this (for personal use)...
http://www.tendosports.com/TENDO-Units.html
I am having a tough time designing the actual device (havent touched arduino yet)
My idea is this:
Measure bar average and peak velocity.
Specs:
String length up to 3m
Digital output from rotary sensor
Minimal tension on the retractable string (3-6 oz)
High accuracy
Keeping cost to minimum ($100-$150) for materials only.
So far my thoughts are
microcontroller
String pot or rotary encoder
tensioner as in a id badge retractor
fishing line or thin durable string (teflon coated)
Is this doable? Any advice?
Thanks
