Mojo Maestro Assembly Guide
Damaged or Missing Parts All kits and parts are checked before being shipped to you. If something arrives damaged or if your kit is missing a part, please open a support ticket to inquire about a replacement. Missing parts will be replaced at our expense. Damaged parts should be returned for verification. If the part shows signs of use beyond what was necessary to determine that it was damaged, DIY Recording Equipment, LLC reserves the right not to replace the part.
You'll need the tools below to complete this build.
We recommend an adjustable-temperature station, such as the $40 Weller WLC100.
You can use 60/40 "leaded" solder or lead-free. We recommend 60/40 because it flows better and is easier for beginners to use.
You'll need a pair of good "snips" for cutting of the excess leads after soldering.
These tools aren't strictly necessary but can make your build a bit easier.
If you find the color bands on resistors a bit hard to read, you can use a meter to sort them with absolute confidence.
If you accidentally solder something in the wrong place, a desoldering pump can save the day.
Print the Mojo Maestro Component Sorting Sheet (PDF) to make identifying the parts easier.
Place the shorter side of the 8-pin header through from the bottom of the PCB. Then solder the header in place.
Place IC Socket
Place the 8-pin socket in the IC1 position. Make sure to line up the notch in the plastic of the socket with the notch drawn on the PCB. Then flip the PCB over and solder the socket in place.
Place the resistors in their respective places on the PCB. Note that R3 is actually 1.6k, not 1.5k as marked on the PCB. As you insert each resistor, bend its leads against the bottom of the PCB to keep it in place.
Solder the resistors to the PCB and trim their leads.
Place Bag 3
Place the parts in bag three, paying close attention to the polarity of C2 and D1, D2. C2's positive lead is longer, and the negative lead is indicated by a stripe on the body. Place C2 with the positive lead next to the "+" marking on the PCB. Place D1 and D2 with the stripes on their bodies matching the stripes on the PCB. Then solder and trim the parts.
Place the IC in the socket so that the dot on the body of the IC is on the same side as the notch in the socket.
Before you wrap up, check the following things:
