    Before ​​starting​​the​​kit... Prepare ​ ​the​ ​following​ ​tools: ● soldering ​ ​iron​ ​(15-20w) ● flush ​ ​cutters ● n2. ​ ​hex​ ​screwdriver​ ​or​ ​allen​ ​key​ ​(enclosed​ ​with​ ​kit) ● needlenose ​ ​pliers ● protective ​ ​eyewear we suggest to work in a clean and a well lit and ventilated envi...

    Add ​ ​the​ ​​3,5mm​​jack​​connectors​​ ​(2x). 6.

    Insert the ​ic sockets (2x; 8 pin dil). Just be aware of the ​right direction of sockets - there is a notch ​ ​on​ ​the​ ​sockets​ ​that​ ​has​ ​to​ ​match​ ​with​ ​the​ ​ring​ ​on​ ​the​ ​pcb. Add the ​ceramic capacitors now. There are just four of them of the same value - 470nf (they are marked ​ ...

    Now let's do the ​female pinheaders​: ​2 pin ones (6x) and ​3 pin ones (8x). It may take a little patience to ​ ​insert​ ​them​ ​well.​ ​be​ ​sure​ ​to​ ​solder​ ​them​ ​straight. Go for the ​switch now. This may be one of the parts that is a little tricky to solder. Here is ​the soldering tip ​: st...

    Next move to soldering of ​potentiometers (b100k). Proceed the same way as with the switch: install potentiometers in straight, solder just one leg, check the position and solder the rest if there is no problem. Solder the green ​led - be sure to insert the longer lead into the plus (+) hole. Push t...

    You will need the cutted leads from resistors now. Turn the pcb around and give a little bit iron into the remaining " ​hold​”, "​bat_-​” and "​bat_+​” holes. Re-heat them and insert the leads using needlenose ​ ​pliers.​ ​the​ ​leads​ ​can​ ​not​ ​be​ ​connected​ ​with​ ​the​ ​potentiometers​ ​on​ ...

    Take your time now and relax for a while. Then do the last ​double check of all soldered joints at this ​​point​.​ ​after​ ​next​ ​steps​ ​it​ ​would​ ​be​ ​​much​​harder​​ ​to​ ​do​ ​any​ ​repairment. Don’t forget to place the ​ics into the sockets (2x; attiny85). There is a signed ​notch on each i...

    Bend ​ ​the​ ​potentiometers​ ​legs​ ​on​ ​the​ ​edge​ ​of​ ​the​ ​pcb​ ​outwards​ ​(see​ ​the​ ​photo). Now ​ ​place​ ​the​ ​​battery​​holder​​ ​to​ ​the​ ​pcb.​ ​watch​ ​out​ ​for​ ​the​ ​​orientation​! 12.

    Mount the holder with ​spacer and the longer ​screw​. It may be a little tricky. Don’t tighten the screw too ​ ​much​ ​because​ ​you​ ​are​ ​dealing​ ​with​ ​plastic​ ​material,​ ​you​ ​know. And now the last soldering challenge! You have to connect the leads with the lugs. ​do not let the lug heat ...

    Now you can complete the kastle with the plastic case parts. Start with the ​side parts (push them just in the corners). Finish it with the ​top cover​, mounting the ​nut (to the switch) and ​screw​. Again, please ​ ​be​ ​gentle,​ ​you​ ​should​ ​not​ ​use​ ​too​ ​much​ ​power​ ​to​ ​put​ ​the​ ​par...
