Following the build guide that’s currently available should be sufficient, there are a couple of things to remember that aren’t mentioned in it, however.
First, when it tells you to use some wire to solder the Li-Po charging circuit to the main board, just use a couple of the legs that you’ve trimmed off of other components.
Second, when the guide tells you to solder the transistor and voltage regulator, the flat side of each needs to face the white square that’s printed on the board so that they can then be bent down on top of those squares.
Third, the newer version of the kit comes with a couple different resistors, they’ll still be roughly the same value but they’ll look different to the pictures in the guide so you might need to find an online calculator to work out their values first.
If you come up against any other issues while making your kit then have a quick look in the support section of the forum to see if anyone else has had the same problem and ask away if you can’t find anything.
