The TuBika DIY kit contains all electrical and mechanikal parts you need to bring TuBika alive.

Not in the kit is  the Power supply  and the Case. 

Include the Kit are all PCB's, the LCD, spacers and screws, Resistors and capacitors, IC's, IC sockets and Atmega CPU - pre progammed.

You can also select  your filtertypes. Same price for SMR4-plus, SVF, Ladder or P4.

Default and good sounding filter are the SMR4plus - usefull for all kind of music

I recomend  4 x the same voice - SMR4 for example and 2 different filter like 1x Ladder 1x SVF or 4P.

If you want to play only poly  you should use 6x the same filterboards , SMR4-plus  for example.  

Building time : motherboard 2..3 hours , each Voicecard  2 hours, adjustment and case mounting 1..2 hours.

Building time means   solder the parts , clean the PCB , check all parts again  , solder points  are OK ??

mesaure the Voltafge on the testpoints and so on . We are not in a race . Good  mounting  take its time.
