Dear Volks,

Since my stroke, I find I need a therapy device that is not generally
available and maybe someone here who is into electronics can point me in
the right direction.

I  need to exercise my hand and arm by pointing. It is actually a
coordination exercise. I need to actually touch what I am pointing at
repeatedly and the object pointed at needs to change positions randomly.
What I propose to have made is a panel with lots of little LED lights which
will light randomly and stay  lit long enough for me to extend my arm and
touch the light. Needed is a random pulse generator to work the lights. I
have no idea how that would work or how it would need to be wired but
surely there must be a way. The length of time the lights stay on must be
adjustable.

I solicit your suggestions, comments and help.

Thank you,

John
