Around the December holidays I received three sets of the jyetech lcd scope kit. This cheap kit (~£10) builds a small low frequency (1Msps) oscilloscope.
In all it took me about 2 hours to solder everything together, that includes me misplacing a resistor and a capacitor. I wish I had sorted the resistors with a multimeter that scales automatically before starting.
I am planning to build these kits into some audio projects later in the year, getting three of them was great luck. The kit was really straightforward to build and didn't take too long, there are serial logging features on the board as well. This kit could be built into a portable work bench without much thought.
