Here you can see 3 different electronic kits, 2 of which I found at garage sales and one I found at a surplus store.
1) A 75 in-one kit. It is an older kit and was from Radio Shack.
2) A 130-in-one kit, again it came from the old Radio Shack stores. It to is an older kit.
Both of these were found at garage sales and cost very little to buy.
3) A 300-in-one kit(the white one). This is a new kit and it allows for the mounting of microchips and electronic parts. It was at a surplus store for about a third of the cost.
These kits are great. They allow you to put circuits together for testing without any soldering. It makes it easier to try different things without having to solder and desolder parts to see if they will work together. If you intend to build anything with electronics this is a good way to test it and I believe most labs should have one or two.
