Minimalist high voltage programmer for Attiny45/85
R1 - R6 = 0805 1k resistors
T1 = SOT23 MMBT3904LT1 NPN Transistor
U1 = Attiny45/85 Through Hole (Use Socket :D )
U2 = Attiny45/85 QFP SMD (Tape that sucker down! )
D1 = Any suitable reverse protection diode (Cause it’s hard to put the smoke back in!!!)

Abbreviations: SDI - Target Data Input
SII - Target Instruction Input
SD0 - Target Data Output
SCI - Target Clock Input
+5V - Target VCC
RST - Target Reset
GND - Ground

Based on the popular Digispark model. The Neospark features 10x WS2812B Neopixels, and an upgraded Voltage regulator to supply more current to drive all the RGB goodness.

The device can be used in combination with the neopixel library to illuminate just about any project, or you can simply use it as a starting point for a neopixel POV display!
