| Liz: Alex is ten years old. He lives in Texas.

!

| He shared his most recent school project with us.
| It’s a great project and a fantastically clear
| tutorial: we thought you ought to see it too.

...

| I was very nervous about taking it into school
| – the last boy that took an electronic clock into
| school in Texas got arrested, so my Dad contacted
| the school first to let them know. I think my
| teacher was impressed, I had to explain everything
| in detail to her.

Amerikanische Kinder dürfen alles. Das Geràt ist ziemlich gut geworden,
aber ich hàtte vermutlich mein Zehnjàhriges nicht mit 170V Gleichstrom
herummachen lassen.

Immerhin:

| Soldering took a very long time. Before we turned it
| on, my Dad checked over everything, making sure the
| 170V was safe. He found a couple of shorts that had
| to be fixed.

Dennoch: Netter und lesenswerter Bericht; es kann für unser Steckenpferd
nur gut sein, wenn ein kleiner Bub (von seinem vermutlich begeisterten
Vater) damit infiziert wird.

Das Risiko dürfte angesichts des offensichtlich begrenzten Stroms
überschaubar sein:
"This takes 12V and turns it into 170V."

In der Tat: tolles Projekt.

Schöne Grüße,
