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
