Elektronicaknutselaar. Ik houd me vooral bezig met het repareren van (met name Apple) computers op componentniveau. Reflowen, nameten, schema's uitpluizen etc. Ik heb wel zo'n beetje elk modern type van Apple over de werktafel gehad. Momenteel doe ik wat rustiger aan met projecten aannemen voor anderen zodat ik meer leuke dingen zelf kan uitvinden.
Blog
Veel van mijn technische avonturen schrijf ik op mijn Tweakblog bij Tweakers.net: http://knutselblog.tweakblogs.net
Artikelen voor Tweakers
Ik schrijf tegenwoordig ook eens per maand een artikel voor de frontpage van Tweakers, in de rubriek 'Hardware 112':
