Hitechbuzz anything you want an indicator for. It has a built in current limiting resistor But it works from approx. 2.5v with about 5ma and up to 15v just higher current. It is about 20ma @ 12v.

Hitechbuzz The plug into the power unit is a standard IEC type so it would be readily available on a cord to fit your mains power.

Hitechbuzz Spc's say 1Hz - 65534kz on the DDS output and up to 1.5v that should drive any av input amp. on chair

Hitechbuzz Could I use spokes for 26" instead of 20"spokes

Hitechbuzz If you say it works with WIN 10 tell us how? I am extremely disappointed as it does NOT work I now have two lovely looking aluminum boxes one used to work with Win 7 but after upgrade to Win 10 didn't work any more software from company is useless.
