The The Three Fives Discrete 555 Timer Soldering Kit is a faithful and functional transistor-scale replica of the classic NE555 timer integrated circuit, one of the most classic, popular, and all-around useful chips of all time. The kit is lovingly designed to resemble an (overgrown) integrated circuit, based around an extra-thick matte-finish printed circuit board. It comes complete with a beautiful aluminum display stand that gives the circuit board eight legs in the shape of DIP-packaged integrated circuit pins.

screw holes attaching legs not threaded - appears to be an oversight.
quick and easy and well documented kit.

Good fun, skyrocketed my nub soldering skills in just 1 hour :)
I went from sloppy but able with a soldering iron to putting out good looking connections almost every time with this :) Pay attention, and know what a good solder join looks like and you get plenty of practice right here lol.

Dead-Simple Assembly, Looks Great
This couldn't have been simpler to assemble. Clear instructions and well labeled parts. If you played with 555s as a kid you'll love this and the 741 kit. Also a great way to figure out how the 555 works internally.

Great electronics kit
This is a great little kit to build. The idea is the build of a circuit that performs just like the real 555 timer chip. The design is easy to build the kit has all the parts clearly labelled and the circuit board has a silk screen layer that makes assembly very easy. Once built I tested the design with a simple LED Flash circuit both on the Three Fives and real 555 IC, both worked as expected. If you read some detail from the data sheet you can learn a lot about basic analogue electronics.
