    What is the Drone Lab?

    The Drone Lab is a 4 voice analog drone synth, rhythm generator and FX processor. It is capable of generating rich, textured soundscapes, hypnotic drones and complex rhythmic sequences. It features a series of filter and distortions circuits as well as an audio input jack. This allows it to be used as an effects processor for external audio signals.

    Drone Add-Ons

    The Drone Lab was designed to invite modification and expansion. A series of add-on modules are in the works. Ideas and suggestions are welcome!

    Building a Drone Lab

    The Drone Lab is being sold as a kit as well as in finished form.
    Detailed build instructions will be posted here soon.
    You’re welcome to buy the PCB and parts from us or build it all from scratch.
    The Drone Lab plans are completely open source and available below. We encourage others to use and adapt the plans as they like.

    What is a DRONE?

    A drone is created by slightly de-tuning 2 oscillators. This creates a rhythmic phase canceling effect as the output waves line up and diverge. The density of the drone can be increased by adding more oscillators tuned by harmonic steps above or below the other oscillators.
    The Drone Lab is engineered to allow for the creation of dense, pulsing drones. A series of filters and a distortion circuit have been built in to add more depth and variation to the drone.

    TREMOLO (volume modulation):
    In order to create movement in the drone we developed a complex, interlinked tremolo system with independent controls for each of the four oscillators. Each oscillator has a tremolo on/off switch, an inversion switch and a pulse divider adjustment. Each of the four tremolos are controlled by one master clock. The divider adjustment creates sub divisions of that clock. The sub division output is then used as a volume control signal for the oscillator.

    In the drawing below you can see the master clock rate and how that rate has been divided. The length of the division is set using the “division” knob. The illustration also shows how the pulse can be inverted using the “invert” switch.


    TREMOLO CLOCK. The master clock is totally modular, meaning it can control the clocks in other Drone Labs or be controlled BY other Drone Labs. This means any number of Drone Labs can be linked together to make extremely complex rhythmic sequences.
    It can also be synced with other gear like modular synthesizers, drum triggers or old drum machines with a trigger output.

    AUDIO INPUT. Any audio signal can be added to a drone and run through the distortion and filters. The input goes through a preamp, so un-amplified signals like a guitar or microphone can be used.


    The Drone Lab V2 is based on the architecture of the V1 with a number of substantial improvements.

    -Interfacing added. Audio input jack and tremolo clock syncing
    -Fine tune pitch control added for each oscillator
    -Improved fuzz stage
    -Improved and expanded divider/tremolo feature

    Oscillator bank.
    De-tune and fade the volume of four oscillators to create rich drones.
    Audio input
    Add external signals into your drone or use the Lab’s filters and distortion as an FX processor.
    Low pass filter
    Modify the tone of the oscillator bank and input signal before it goes into the distortion.
    Adding distortion brings out the phasing rhythm between two or more tones.
    Band pass filters
    Two slightly resonant band pass filters can be adjusted to drastically alter the tonal character of your sound. Achieve wah-wah and phaser sounds as well as creating classic analog synth filter effects.
    Tremolo bank
    Add movement to drones and create interlinked pulses and complex sequences. Sync the master tremolo clock to a limitless number of other drone labs to create a rhythmically linked drone orchestra. Alternate clock sources may be used such as modular synth clocks, drum machines, piezo triggers and simple DIY clocks such as the 555 timer.
    Battery or wall power
    The Drone Lab draws very little power and will work for days straight on a single battery. In the event the you don’t have a battery it can also be powered using a standard 9 VDC wall wort power supply.
    Add your own circuits!
    It may be small, but a proto area has been added to the board to allow for simple circuit addition. We’ve got oodles of ideas that we’ll post as the project goes on. Hopefully others will contribute their ideas and designs as well.



    Here’s a sample of the Drone Lab doing it’s droney thing.


    0:00 fade in single tone.
    0:05 second tone added.
    0:11 light distortion added.
    0:14 Low pass filter turned up.
    0:19 Band pass filter turned up.
    0:27 Third tone added.
    1:05 Fourth tone added.

    Here’s a sample made using the tremolo feature.
    Tremolo drone

    Distorted drone
    I don’t usually post samples of my gear going through other effects, but I have to show off how great the Drone Lab sounds with distortion. This sample was made by sending the Lab through a distortion/feedback circuit I’m working on specially for future versions of the Drone Lab. It’s a little unruly for a lot of sounds but works wonders on steady drones.

    Here is a video of 3 of the first Drone Lab prototypes going at once. This video really shows how well they work together.



    To test our board design we burned our own two sided board. Totally crazy. Somehow it actually worked!
    It was an absurd amount of work and I hope to never have to do this again!

      Wayn3w, we designed the board to be straight forward, and easy to assemble, so we went with board mount components. The board is capable of being a standalone musical instrument. Components can still be mounted to the board via flying wires, and the device can be housed in any form of enclosure the builder wants, or left without an enclosure.

      That is exactly why I’m selling a parts kit and why I put all of the hardware on the PCB. In one afternoon you can build the whole thing.
      I’m a habitual PCB buyer and I have so many unfinished modules. I wanted the drone lab to be easy to build without skimping on features or on upgrading/DIY potential.

      I wouldn’t call this a beginners kit simply because there are so many components. BUT relative to analog synth circuits and audio kits, this is a very simple kit mainly due to the fact that everything is mounted on the board. No flying wires, complex wiring diagrams are necessary, which is where I’ve had the most difficulty with kits in the past. If you are really good at going slow and following directions you’ll probably be alright.

      Dead Beat:

      Crosstalk and noise are caused by EMF, or Electro-Magnetic Fields. In a circuit, rapidly changing currents in wires cause these fields. The strength of these fields are proportional to the flux, or rate of change, of the current in a wire. Because the Drone Lab uses square wave tone generators, every time the square wave changes phase (twice every cycle or 880 times a second for a middle “A” pitch), there is a corresponding quickly changing magnetic field created around the wire. This changing magnetic field induces a changing current in nearby wires, which causes signal crosstalk and noise generation. This phenomenon has not proved to be particularly problematic with this design, but introducing lots of unshielded flying wires to off board components runs the risk of creating more of this noise.

      ” This phenomenon has not proved to be particularly problematic with this design, but introducing lots of unshielded flying wires to off board components runs the risk of creating more of this noise.”

      How would one alleviate this risk/problem, in general? Swap to shielded wire only (or is that a more complicated endeavor than it sounds?) I’m researching DIY kits and this is a general question I’d love to know the answer to, since I am all about making my own enclosure, and attempting to combine/collide/experiment in general with other circuits and kits =]

      Erm… Do you think you could add another image or chart breaking down what each of the caps is (electrolytic vs. ceramic vs. film, etc.)? I know you plan on adding the distributor numbers, but having it on a chart would be super handy! Thanks again for this! I’ll be putting in an order fairly soon (money willing!)!

      October 27th, 2009 at 7:47pm #

      I will add more details on the components but here is what I can tell you now. This is a pretty flexible circuit so component specifications are somewhat loose in regards to values and especially when it comes to component materials.
      Anything 1uF or higher is electrolytic. Anything below that is pretty flexible. I’m using a mix of ceramic and film but mostly ceramic. What is most important is that you get caps rated at 5-10% accuracy. Some caps are rated at 80% accurate! That means it could be WAYYY off the marked rating.

      Shielded wires should help to eliminate noise from flying wires. Remember to ground the shielding material. We built a prototype with long flying unshielded wires and it was noisy, but still sounded gnarly! Goodluck and look forward to seeing your enclosure!

      Hello again -
      I spoke to an audio engineer friend of mine and had him look at the schematic as regards suggestions of the type of capacitors for each section of the circuit. Here are his suggestions (these are by no means required) if you are self-sourcing your kit to ensure the best (read: most precise) out of the circuit. I’d love to hear what everyone else thinks (especially you, casper!) about this!

      C5,C6,C25,c34,c42,c38 Panasonic audio electrolytic

      C24,C26,c31,c30,c32,c33 Wima audio film capacitors

      C8,c9,c10,c11 (Timing), Wima film capacitors

      All others can be ceramic.

      Any thoughts?

      The pots are made by CTS and they are pretty solid. I’m really happy with them, but they’re kind of hard to find. I found some by a company called Vimex that are a perfect cross but they’re even harder to find. I also found some Alpha brand but haven’t tested them yet.

      2 tracks of unaffected Drone Lab. I bring in the ocsillators one at a time, then add the distortion in a fade that lasts almost 4 min.

      i have a question – & sorry, my english is not sooo good ;)
      i think about ordering an drone lab, but i want to know, if i can use it with a step-sequencer.
      for example the urzwerg/from mfb…
      i found in the specifications: “it provides four Gate- and CV-outputs to control compatible analogue synthesizers and modular systems. Start-I/O and Clock-I/O allow urzwerg to be synchronized to and sync other analogue sequencers. The additional CV-Clock-input allows for dynamic tempo-control, e.g. using an external LFO or a CV-controller.”

      or the darktime from doefer, which will be realesed 2011: it has also “analog interface for CV/gate/clock/Start-Stop (inputs and outputs, 3.5 mm miniature jack sockets)”

      so is it possible to connect the clock out from a sequencer with the tremolo clock interface/in to control the speed?!
      and the other question is a pricipal one: makes it sense to use the drone lab with an analog-sequenver?!

      maybe that are stupid question, but i am a beginner :)
      best regards, BANtastic

      This looks/sounds awesome. I’m an absolute beginner in the world of electronics, but I think I’m gonna go for it. I’ve been dreaming of a synth almost exactly like this for several years now, but had no idea how to go about building it!
      So, I’ve got a couple of questions before I order up:

      1. What’s the approx. price difference if I were to order the parts myself vs the kit that comes with all that. Is it really that much of a hassle to source the parts?

      2. What’s the pitch range of the oscillators on this thing?

      just to clarify – if i were to connect the snare output of my mfb 522 drum machine (sending a snare signal on the first beat of each bar) to the tremolo clock in – would the drone lab be able to use that as a synchronization source?

    • 50

      casper said:
      April 2nd, 2011 at 1:28pm #

      you should be able to use most any square wave hat is above 2 volts. The length of the pulse will have an impact on the tremolo length. Ideally you want a clock with a 50% duty cycle. The snare output is probably a 10% or so duty cycle relative to the length of each bar.

      The kit arrived in good time and was huge fun to build, with an excellent quality PCB.

      I made one mistake with the placing of the D8 cathode, which stopped the tremolo from functioning; but everything worked perfectly once I’d spotted the error. All in all, it took about ten hours to build and debug, including a few breaks for tea.

      I’m delighted with my Drone Lab V2 and amazed by the range of textures it can produce. Be warned that playing it can be a hypnotic experience, where hours pass like minutes.

      Buy one. Now.

      Hi….just bought an assembled drone lab off ebay BUT i dont think the guy has put it together properly! volume is super low unless I use distortion and the BPF freq 1 & 2 dont work at all! I have zero soldering or electrical skills. Any ideas? Help!

      Have been pondering over buying a drone lab kit ever since the first prototype and have just got round to purchasing. Cannot wait to get this thing built.
      Keep up the good work casper

      We haven’t publicly announced this yet, but we are planning to discontinue the DroneLab in order to fully support several new kits. We currently have 50 PCBs remaining and do not plan to restock once they are sold out. We sell about 1 or 2 a week so there should be PCBs and parts kits available for several months.

      Hi, sorry if this is kind of off-topic -I was wondering what CAD you usually use for schematics and pcb design..

      Hi frank. We used ExpressPCB for the drone lab schematic and PCB. This is a nice enough program for beginners but you can only get the boards you design fabricated through the (expensive) ExpressPCB service. I now use (and highly recommend) Eagle.

      Out of curiosity, when the last 50 are sold how many Drone Labs will there loose on planet earth? Haven’t built mine up yet but hoping to have it finished this week.
      Really excited to see what these new projects will be! How long will we have to wait for them?
      Thank you so much for this site and all the resources you’ve made available, you’re a great builder!

      I’m trying to build a drone lab based on a earlier version, the drone lab single schematics 2. There are diodes on the schematic that don’t have vales marked on them like the ones used in the fuzz filter.Then the two going to center frequency 2. If you could let me know what kind they are that would be great! I’m trying to learn how to do this and this is an amazing instrument!Thank you for your time!

      I’d suspect they are 1N914 diodes…as a best guess.
      That, or he didn’t specify on purpose.
      Generally for diodes on a distortion circuit they can be almost any small signal diodes. Germanium, Silicon, or even LEDs.

      i finnish try building the drone lab ver.s but i found a few things that made me confused.
      1.for the distortion i dont get the fx… very low effect, than i check again the PCB no wrong … and i tried again but i stiil get the low distorstion..

      2. the 40106 overheat… it`s true..? i found many article, if we used 3- 4 gate osc the IC`s will overheat….

      thx.. for may bad bad english…

      Hi Casper,

      I was lucky enough to get a used drone lab V2 Ver 2.1.
      Unfortunately it does not have the housing. Do you by chance happen to have any 2.1 housings somewhere still in stock? If not, can you supply a file with all dimensions for the faceplate as I will try to manufacture a faceplate myself Thank you and keep up the good work.

      The 40106 should not be getting warm… and of course the distortion should be loud :-)
      The distortion is on the top left corner of the board above the tremolo rate knob. First look closely for short circuits, then cold solder joints (this is where the solder is sitting on the component but hasn’t bonded). Check all the polarized components to make sure they’re in the right way (capacitors, transistors, diodes).

      i have question about the tremolo (volume modulation).
      Is that error or no..? when i swith the invert switch on the position modulation input to 2n3906, the the volume output so weak, but when the inversion mod goes to 2n3904 the volume normally…. thank`s for the answer.. :)

      @Jono. I’ve never heard of this problem. Meaning that its something on your end. Perhaps there’s a short in your wiring that only becomes active when you close the switch.

      Hi Casper, I had originally decided to burn my own board, but after a few botched attempts (Ive never made a board this size before, let alone double sided…) I am left with a faceplate kit and no PCB. Are there any more kicking around these days? If not, is it possible you could send me a brd or pcb file so I can hit up a fab house for one? Thanks in advance, still loving my Nova Drone!

      Seems the DL forums are kinda down or something.
      Im getting weird character displays at the gostwizard site where the forums are hosted.

      Has the forums moved??

      i find EXACTLY what i need (eer well really really want) it creates the sound scapes i love and i’m too late. lets hope there is enough push back and it can be raised from the dead, the zombie drone. Cracking work, a credit to the community.

      I’m looking for a fully assembled Drone Lab v2 (with plexiglass cover). Anywhere I can still find one? Or if anyone has one to sell get in touch with me:

      UK/EU preferred but elsewhere will be considered.
