    Before ​​starting​​the​​kit... Prepare ​ ​the​ ​following​ ​tools: ● soldering ​ ​iron ● multi-meter ● flush ​ ​cutters ● n2. ​ ​hex​ ​screwdriver​ ​or​ ​allen​ ​key​ ​(enclosed​ ​with​ ​kit) ● isopropyl ​ ​alcohol​ ​+​ ​smaller​ ​and​ ​clean​ ​brush​ ​(optional) ● protective ​ ​eyewear we suggest t...

    Soldering resistors start soldering with the ​resistors​. There are just ​three ​values of them: ​22k (14x), ​100r (2x), and 220k (1x). Before you will start soldering, check the values by using a multimeter (or you can check 4 the color codes if you are seasoned enough). Snip the leads close to the...

    Diode next solder the ​1n4007 ​diode - ​be careful, diodes are polarized! Make sure that the grey stripe on the ​ ​diode​ ​matches​ ​the​ ​stripe​ ​on​ ​the​ ​pcb. 5.

    Jack ​​connectors add the ​3,5mm jack connectors (6x). They have to be soldered precisely down on the pcb. You can start ​ ​soldering​ ​just​ ​one​ ​leg​ ​of​ ​each​ ​connector,​ ​check​ ​it​ ​and​ ​then​ ​do​ ​the​ ​rest. Ic ​​sockets insert the ​ic sockets (2x; 8 pin dil). Just be aware of the ​ri...

    Ceramic ​​capacitors move ​ ​to​ ​the​ ​​ceramic​​capacitors​​ ​now.​ ​first​ ​solder​ ​the​ ​​22pf​​ ​cap​ ​(1x)​ ​which​ ​is​ ​marked​ ​"220". Then ​ ​do​ ​the​ ​​470nf​​ ​ones​ ​(they​ ​are​ ​marked​ ​"474"​ ​on​ ​itself​ ​and​ ​there​ ​are​ ​eight​ ​of​ ​them). 7.

    Leds solder the ​leds now - ​these are polarized too​! Be sure to insert the longer lead into the plus (+) hole. Place the leds down to the pcb. It is better to solder just one leg first and then do the adjustments ​ ​by​ ​resoldering​ ​and​ ​repositioning​ ​at​ ​the​ ​same​ ​time. 8.

    Voltage ​​regulator now you can do the ​voltage ​regulator (​l78l06​). The ​flat side has to match with the printing on the pcb. Electrolytic ​​capacitors don't forget to solder also the two ​electrolytic ​capacitors (47μf)​. These ones ​are polarized! ​there is a plus (+) sign on the pcb that shoul...

    Fuse there is also one ​fuse (​100ma​) to solder. It is not polarized and it looks almost like a ceramic capacitor. ​ ​then​ ​snip​ ​the​ ​overhanging​ ​lead​ ​a​ ​little​ ​bit. Power ​​connector let's ​ ​add​ ​the​ ​​power​​connector.​​ ​just​ ​be​ ​sure​ ​to​ ​solder​ ​it​ ​flat​ ​with​ ​the​ ​pcb...

    Buttons go for the ​button switches now. Be aware that these parts have to be ​oriented​! There is a marked line on the one side of button which has to be oriented upwards. Remember to solder these switches straight. ​ ​see​ ​the​ ​pictures​ ​before​ ​soldering. 11.

    Potentiometers move to soldering of ​potentiometers (a100k). Install them in ​straight (you have to push them down), solder just one side leg, check the position and do the re-heat and repositioning adjustments in need. Then solder the rest if there is no problem. Remember - they have to be soldered...

    Cleaning ​​(optional) before you begin to move forward, you might want to ​clean your pcb. You can use e.G. Isopropyl alcohol. Put some of the liquid all over the pcb using the brush, let it act for a while and sweep it off. Then ​ ​just​ ​let​ ​it​ ​dry.​ ​you​ ​can​ ​repeat​ ​these​ ​steps​ ​until...

    Battery ​​holder before placing the battery holder you have to do a little adjustments. See the photo and first cut the signed ​ ​legs. 14.

    Take the remaining leads then and solder them into the holes near the power connector. It is good to melt ​ ​some​ ​solder​ ​into​ ​the​ ​holes​ ​first​ ​and​ ​then​ ​reheat​ ​them​ ​and​ ​place​ ​the​ ​wire​ ​inside. Let's secure the battery holder now with the ​spacers and ​screws (the longer ones...

    Now you will do the soldering. You have to connect the leads with the lugs. ​do not let the lug heat too much! (it would break the connection of the coil and the lug) use just the tip of your soldering iron for ​ ​a​ ​second. You ​​are​​almost​​done... Now you can complete the dude with the plastic ...

    Then ​ ​place​ ​the​ ​​side​​parts​​ ​(push​ ​them​ ​just​ ​in​ ​the​ ​corners). Finish ​ ​the​ ​enclosure​ ​with​ ​the​ ​​top​​cover​​ ​and​ ​mounting​ ​the​ ​​screws​. Here ​ ​it​ ​is,​ ​your​ ​dude​ ​is​ ​finally​ ​completely​ ​alive!​ ​congratulations! 17.
