Version 2.1
Updated January 7th, 2009
These diagrams will serve as a step-by-step document to aid in the
assembly of your Drone Lab!
To start off, you are going to be needing a number of materials and tools:
- Soldering Iron
A cheap radio shack unit will technically work, but a nicer temperature
controllable iron will save time and frustration.
- Solder
Whatever type you prefer, small gauge solder helps avoid excessively large
joints.
- Wire Cutters
The type with the flat cutting edge for nipping leads off close to the board.
- Needle Nose Pliers
- Flathead Screwdriver
- Solder Wick
Extremely helpful when removing shorts / de-soldering joints.
- Multi-Meter
Extremely helpful in debugging. Get one that beeps when it detects electrical
continuity, and learn how to use all the functions!
Here’s the parts that are required to build a functional Drone Lab. They are all included in the
kit. In the following pages you’ll see pictures of each component. If you purchased a kit,
please make sure you have all of the components shown. There was great effort paid to
making sure all of the kits went out complete, but if indeed a mistake was made contact us
directly. Note, if you received an enclosure, you should have received a hardware bag that
includes nylon standoffs.

It is highly recommended that you sort the bag of resistors into piles
before proceeding to assembly. Each diagrams is a screenshot of the
board with the component for that page highlighted. With the
components sorted, assembly will be more efficient.

The Resistor Color Code:
For the kit resistors, ignore the 3rd Band.
-Note: For those who purchased kits, the kit ships with 5 values of capacitor that look almost
identical. Written on them is the capacitor code, but the kits were assembled in such a way that
the quantity of each of these similar-looking capacitors is also an indicator.
-Another Note: The radial capacitors (220, 100, 10, 2.2, and 1 uF) should be inserted so the
longer lead goes through the square hole. THIS IS DIFFERENT FOR THE LEDs.

The transistors’ physical shape should match the silkscreen of the component
from the top. Otherwise the transistor will not function properly.
Note: The transistors should be installed before the switches.

-Note: After the potentiometer has been inserted into the board, the legs can
be bent apart to ensure a strong hold of the board. This will keep torsion load
from twisting the knob from loading the active electrical solder joints.

The Drone Lab was designed to be simple and expressive. It was also
designed to be modified and hacked. There is a small area to the left of the
audio jacks for custom circuitry, and many breakout points where wires can
be soldered in, and traces can be cut to enable users to modify the signals.
The Drone Lab was designed to be a fully functional
synthesizer using nothing but the board and components.
However, the circuitry can be housed in any number of ways,
and custom switches, potentiometers, and LED indicators can
be added by the user. It’s your Drone Lab, do what you want
with it! This section of documentation will show some points
we thought would be useful to have easy access to, and
provided breakout holes for wires for just that reason. If you
come up with any interesting modifications, please share
them with us and the rest of the Drone Lab community on the
forums! Happy Hacking!
For Version 1.2 of the board, we have provided a mid-board breakout of all connections running to the potentiometers
of the Drone Lab. This allows for the board to be cut in half for more flexible enclosure designs. Below is a labeling
system that will help with running flying wires to potentiometers. When in doubt, follow the traces or use a multi-meter!

This isn’t the easiest to assemble kit out there. Still, with a little patience
and attention to detail, especially in creating great solder joints, the unit
should be able to be built within 8 hours. If it doesn’t work the first time do
not despair, our units didn’t work the first try either.
Some Tips for Debugging:
- Look for missing or loose solder joints, cold solder joints can drive you
nuts! Look to heat up the surfaces of both the lead and pad such that the
solder forms a concave curve to the surfaces.
- When in doubt use your Multi-Meter! Check for continuity where there
should be, and where there shouldn’t be.
- Follow the circuit schematic of failing systems. Look for abnormalities
of continuity or missing / wrong direction components.
- Keep Hope Alive. You’ll get it working soon enough! Remember to have
fun, you’re building an analog synthesizer!
Thanks again for your business, we hope you enjoy your Drone Lab. If you
have any questions, comments, or content, share it on the forums!
