content: FETs should be banned, look hoow dangerous they areI should make one of those, matches myCasio F-91Wwatch.Also nice that it's marked J2, it adds to the confusion when defusing the bomb.

content: As borderline offensive as it is... there is something about the fact that, even with a one-component circuit, they managed to design something with nearly zero chance of actually working, that made me giggle.1V into the gate will probably release the magic smoke, with minimal external heat generated... It's a JFET - the current drawn from the 5V will barely exceed Idss...If any potential terrorist finds this he's just going to waste his time... which is possibly a good thing?

content: Quote from: PA4TIM on October 02, 2013, 09:29:53 amIt may be "sick", but there is no real "terrorist educational potential" in this.Anybody, really anybody, with the slightest knowledge in electronics can make a trigger circuit for whatever purpose.You seem to be offended by thelabellingof the message as "useful for people most of us do not like or simply abhor". However, the label is just that, a label. In this case, neither the messenger not the message is a threat. It is what people do with the message that can evolve into a threat. Reading the anarchist's cookbook does not make you an anarchist, but merely a more informed person (without pinpointing a value on the information or the reader).

content: Those Casio watches are no good, diesel rots the plastic. I had one in the 90's it only lasted a few months and the plastic fell apart. Got a metal casio now diesel resistant to 10 meters.

content: Jfets? Leave it to the pros:That's an actual terrorist bomb trigger. Seems like a very simple circuit using the same Casio watch we are talking about. I can actually make the circuit at home (this message should put me on at least two watch lists. O0 Make that 5 when the US government is restarted again)
