To complete this basic electronics kit a modern designed enclosure is included.

  1. Great gifts, great solder practice! review by Elijah (Bunk-e) Horland on 1/3/2017

    Recently i have made christmas presents to my teachers, and you guessed it, the presents were these Vu meters. I made five of these, four for my four core teachers and one for my 6th grade vice principal. Even though I made five of them i did not make any simple mistakes, it was easy not to make any simple mistakes because most of the components were in order.

    One great thing about the new kit is that the pads are a little farther apart, that makes it easier to solder and easier to correct mistakes. A lot of the older velleman kits are harder to work with because the pads are too close together. I've learned to solder over the last year and a half, so making good clean contacts is no longer difficult, but these pads will help other kids make theirs work on the first try.

    I would suggest this product to someone who needs to me sure sound in an uncontrolled environment. or a person who needs practice soldering at a slightly higher level. This is now one of my favorite kits because of the fact that is can be used as just a soldering kit and it has a practical use.
