DigiLogiProbe V1

This project has been edited. The original Instructy had far too many words.
I have searched around the web, and I could not locate a mash up like this.
DigiSpark was a crowdfund project to leverage the ATTiny85 chip on a USB board with the bare minimal Interface and power. This very small 2012 developer board has 6 pins. On China built work alike boards, 5 of those pins are useful. Clone boards are less than $3 Cad; original boards are $10 Cad but are sold out temporarily.
I have named my forked mashup design, the DigiLogiProbe V1 or
DIGI (to honor the original Digispark) LOGI (for LOGIC) PROBE.
- use DigiSpark or Clone (with PB5 issue Fuse fixed) Dev board
- 9V (common type 6LR61 or 1604A) battery power
- any Logic level from 0 through 5Vdc, programmable thresholds TTL, CMOS, 3.3V
- indicate PULSE activity
- TONE of LOGIC states, so the thing SINGS to ME. Cool.
- a WHITE flashlight that illuminates the PROBE area! when the probe sense OPEN condition.
- Small size fits into pen type probe DIY housings, or DIY 3Dprinter case or aDIY homebuilt case from a highlighter marker pen with contents removed.
