Colourupter Assembly Guide
For recommended tools and safety precautions, refer to the Colour Pallet Assembly Guide.
The only tools that are absolutely necessary to complete the Colourupter are a soldering iron and clippers. However, a multi-meter is handy for identifying resistors, and needle-nose pliers make bending component leads easier. An attractive, salvaged-wood work surface is also recommended but not strictly required.
Identify the 10 resistors by measuring them with your multi-meter or by reading their color codes. As you sort the resistors, bend their leads 90 degrees at the body to prepare them for insertion.
Note: If you purchased your kit after 1/1/2017, R10 will be 680R instead of 10k.
The resistor values are:
||680R (10k before 2017)
Begin populating the printed circuit board (PCB) by placing the resistors in the places marked for them. Note again, that if you purchased your kit after 1/1/2017, R10 should be 680R, not 10k as marked on the PCB.
As you insert the resistors, bend their leads flush against the bottom of the PCB. This will hold them in place when we flip the board over for soldering.
Now solder the resistors to the PCB. Observe good soldering technique: heat the pad and lead for 2-3 seconds, apply a small bit of solder, and continue to heat the pad for another 2-3 seconds. Allow each solder joint 10 seconds to cool before moving on to the next one. The finished joints should be shiny and should have just enough solder to cover the pad entirely.
Once all of the solder joints have cooled, use your clippers to trim away the excess leads. Your goal should be to clip as close as possible to the joint without clipping the joint itself.
Next, place the socket for the integrated circuit IC1. Orient the socket so that the semi-circular notches on the socket and the PCB legend match.
Using your needle-nose pliers, bend two of the socket's pins against the bottom of the PCB to hold it in place. Try not to scratch the PCB with the pliers!
Solder the pins of the socket and trim the excess leads down to the joint as you did with the resistors.
Next, identify and place the four smaller, red, "film" capacitors. C1 and C2 are marked "u1K63" or "0.1 63". C4 is marked "WIMA 68/1000-." And C6 is marked "3-L 684."Bend their leads as you place the capacitors, then solder and trim.
Next, we'll place the component at the heart of the Colourupter's sound: the "vactrol," or resistive opto-isolator. The vactrol's orientation is indicated by the lead spacing; the vactrol with the labeling on top and the closer leads towards the center of the PCB. Bend the leads, solder, and trim.
C3 and C5 are aluminum electrolytic capacitors. However, unlike most caps of this type, they are non-polarized so they can be inserted in either direction. (The "+" indication on the PCB is included just in case someone wants to use different, polarized caps.)The actual value of C3 and C5 may be 10uF or 4.7uF, depending on the revision of the kit you received. Insert the caps, bend the leads flush against the bottom of the PCB, solder, and trim.
Pop the standoffs into the four mounting holes from the bottom of the PCB. Insert the locking ends with right-angle tabs into the Colourupter PCB and leave the removable ends to be inserted into your Palette.
Finally, insert the 8-pin header into the holes marked "CON1." Make sure to place the short, silver pins through the PCB so that the black posts and long, gold pins protrude from the bottom of the PCB.Set the PCB down so that the pins of the header rest against your work surface and solder the header. There should be no excess leads to trim after soldering.
See how the pins of the IC protrude from the body at slightly wider than a 90 degree angle? In order to fit the IC into the socket, we'll need to bend the leads inward a bit.Set the IC on its side and press from the other side to bend all the leads at once. Then flip the IC over and do the same for the other side. When you are done the leads should be perpendicular to the body.
Set the IC on top of the socket, making sure to align the semi-circular notches. Double check this! Now apply pressure with one or two fingers to press the IC firmly into the socket. Is it really in there? Good, then you're done!
