Hothouse Digital Signal Processing Pedal Kit (MONO Version)
Get your Electrosmith Daisy Seed DSP projects off the breadboard and onto your pedalboard. Create your own digital signal processing effects—or use ready-to-compile code from the companion repository. Just add your Daisy Seed (purchased separately), and head over to the official Github page to get started. Daisy Seed NOT included.

This is the legacy mono version of the Hothouse and we’re selling them at a discounted price until they’re gone!
Available as a kit or assembled and perfect for the typical mono guitar pedal board or other situations where stereo is not needed. If you want the newer stereo version, go here. REMINDER: DAISY SEED IS NOT INCLUDED!
The perfect blend of DIY pedal kit and digital signal processing software, the Hothouse is an accelerator for creating your own Electrosmith Daisy Seed-based, embedded DSP effects.
Electrosmith changed the landscape of DIY embedded digital signal processing with the release of its inexpensive and powerful Daisy Seed. And even though the Daisy Seed is easy to program in languages like C++, Arduino, and Max/MSP Gen~, there is still a lot of work required to make your project real-world ready: you still need to design and build appropriate audio buffers, source electronic components and hardware controls, and then wire up the audio I/O, power, and other hardware like potentiometers and switches. Many projects may even require custom PCBs or perfboard designs. Then, add to that the design of the control layout and precisely drilled holes in an enclosure, it’s no wonder so many DIY projects never make it off the breadboard and on to your pedalboard.
That’s where the Hothouse helps. You focus on the code, and it takes care of everything else.
The Hothouse features high quality circuitry for audio I/O buffering, power filtering, voltage regulation, and noise filtering, all baked right on to the main PCB. All you need to do is solder in the pots, switches, LEDs, jacks, and ribbon cables. Add your Daisy Seed and you’re good to go. Start hacking and hearing your own code right away, or flash your Daisy Seed with any of the GNU-licensed, ready-to-compile effects from the official companion code repository.
Flexible control layout.
The Hothouse gives you plenty of programmable controls for most DIY projects. With a choice to use either 2-position or 3-position toggle switches, the control layout can be tailored to your project needs. You can even mix and match the switch types if you wish; it’s simply a matter of writing your code to handle the required states. The controls provided are:
- Full frequency range! Bass, synth, and drums friendly
- 6 potentiometers
- 3 toggle switches (supports both ON-ON and ON-OFF-ON switches) supporting up to 27 programmable states
- 2 momentary foot switches
- 2 LEDs
- Top-mounted audio and power jacks
- Rugged powder-coated 125B enclosure with professional artwork
NOTE: the Hothouse ships with 3-position toggle switches. If you want to use 2-position toggle switches, you will need to acquire them separately.
An official companion repository on Github.
Get involved. Use the official code examples as a starting point, compile and flash them as-is, or write your own effects from scratch with the provided code template. The growing code repository can be found at https://github.com/clevelandmusicco/HothouseExamples.
