Fast-Settling Picoammeter Circuit Handles Wide Voltage Range - The circuit can be
easily built to a small plastic box with telephone connectors in both ends. The
circuit takes about 10-20 mA current, so if the circuit is not in use all the time it
is best to use batteries. You can also use small wall transformer to power the
circuit. Remeber to take a wall transformer which gives good quality output (regulated

Gold Wafer Cards Circuit - This circuit is a combination of a ludipipo programmer
(for pic) + phoenix programmer (for the eeprom 24LC16). You can't program pic
and eeprom with ludipipo programmer. The big advantage of this circuit is that use
just one port from your computer (RS232) in reverse with other programmers that use
both RS232 and parallel. The disadvantage is that you must select the component to be
programmed with a switch and not electrically and that you can only program 16F84
