Oh yes I certainly do so, after he made his no-avoidable experience with=20
electricity much earlier.
the only way out I figured is education, because total protection is kind=20
impossible, especially
in a workshop kind environment.
So by now he can identify all common electronic components in real life or=
=20
in schematics, draws
simple shematics, knows how to use a DMM, measure voltages and currents,=20
energize motors, relays,
lamps, LED=B4s, and very soon he will know how to use an NE555.
No computer is save, the other day when he didn=B4t want his sister to play=
=20
with his computer he just
unplugged the hard disc, knowing it would come up but not work at all, he=20
just didn=B4t bring the 40 pin plug
in again.
As, someone told me that PIC=B4s are a lot easier to use than a 555, which=
=20
animated me
to give it a try and I found it=B4s kind true, he should be set soon.

Friedel
