Electronic kit building

2 things have re-awakened in my fancy world this holiday. One of them is electronics.

Some pics of the little creepy simple light-attracted bug. It took only half an hour to build. This circuit is nice in only 2 ways, cheap, shows how a motor can drive the bug without any gearing, and thirdly simple, having a very low transistor count.

I was dissapointed on 2 counts with velleman. the website is wrongly silkscreened onto the board as . It should be ,they also have a USA office and site. Why on earth screw up something that important. Secondly (but not last) is they give you 2 diodes, but neither of them have a place on the PCB... well actually I used one as a rear-axle.. and that is where the puzzle lay, because the horrid diagram they provided on the box shows a diode to prevent damage if the battery is the wrong way about (would actually heat the diode a bit IMHO, since it is drawn as going across the supply of 2 AAA batteries.) but it is not on the PCB, unless you solder it onto the underside! UGLY.
Overall a nice simple kit. Next is a microcontroller project He He!.
