Note that the package contains more than necessary for every small component, so you are free to fail a few times!

The usual time to complete this challenge is about two hours for experienced solder masters. Make sure that you are in a relaxed and quiet environment when you start.

; An appropriate soldering tip : The usual instruction is to get the smallest one you can find, but an insider tip is using one with a knife shape:<br>[[Datei:Knife_soldering_tip.jpg|300px|Knife Soldering Tip]]<br>The reason is that you can adjust the size of the contact area by varying the angle you're using it at.

; Solder : Just the regular 60% Sn 40% Pb stuff with rosin core. Do not lead-free solder!

; Pincers : As sharp as you can get. Make sure that they're not bent.

The order of 10/11 might seem weird, but there's a reason: the LED at number 10 is cheating. There are no 01005 LEDs, so this is a large 0201 LED. The actual crown jewel of this challenge is the resistor with the final index.

The IC (the shift register) at the top is relatively easy to solder, but mind the orientation. ~~The LEDs in~~ the ~~left column also have an orientation~~, ~~and that took me~~ the ~~longest to actually get right~~.

The IC (the shift register) at the top is relatively easy to solder, but mind the orientation. After that, insert the battery and test every time you complete a row. You shouldn't solder a board with power connected, but the switch on the backside disconnects power mechanically, so keeping the battery in is fine on this board.

Unlike throughhole LEDs, SMD LEDs show their orientation on the ''backside'' of the part. You have to flip them, look at them with a microscope, rotate them correctly and then flip them back (making sure that you don't rotate them while flipping them back). Here's the symbol guide:
