the picture of this mofet testor, is very neat. i used a large intergrated circuit socket and cut out 3 sections to use as a mosfet socket, to plug the mosfet into, before testing it, i sent one of these simple n channel mosfet tester to a friend of mine and he took it in to show some coleages of his. they had a really exspensive n channel mosfet tester but for the size and super cheap price it costs to biuld mine. they were imppressed.

be carefull when selecting the 1m resister here as they look like a 10m resister unless you look at it under a bright light  to see the colour band properly  as the blue band in a 10m resister looks almost like the green band in the 1m resister

to speed up the n channel mosfet testing, change the electro to a 2.2uf 100 volts electro
