- knobs! buttons! flashing lights! weird noises! an easy budget homebrew synth based on raspberry pi, "lots-of-pots" hat from modern device and purr-data (pure data) synthesis - step-by step instructions for how to build this are on my site - a working knowledge of linux will help just in case you run into problems - sites.google.com/view/plastic... - cost for the whole thing should be less than $140 or cheaper of course if you already have a pi knocking around
Really like the box. With that camps like Guantanamo Bay are pretty much unnecessary. Gets all answers out, no questions asked.
Great .... this is exactly what I've been looking for. I've got a couple of old Raspi's hanging around, ready to be turned into synths. I wasn't sure if PD would run on them, but this sounds great.
Nice!
Congratulations
Cheers. :)
Hello! It's pretty impressive for such a micro-computer! I'm wondering - is it possible to assemble the equal setup using Raspberry Pi Pico + some IO + memory modules + encoder HAT? Or it certainly need a full Raspberry? I'm going to order one tomorrow so it's a kind of dilemma to me. I would like to have more "ready-to-use" setups in parallel but I don't have enough money to spend on full Pi's. Also I've heard (not my info) that encoders works better on Pico. The person did mentioned that a full Pi can skip encoder's steps because of CPU load.
Wow! I've been looking for building something as nite as thins for a long time! Thank you so much for sharing your knowledge :D
I dream using your project with the integration sampler, as an independent stand-alone unit (controlling the lunch of the sounds via midi messages). Do you know how to build a sampler with pure data and how to added to your project? I am learning pure-data but I don't know to much yet .
Will this run on a pi B ? Whats the minimum pi version?
how did you get 8 analog inputs for the pots into the pi?
The features of the LOP board include:
Eight 10-bit analog inputs via a MCP3008 analog to digital converter, connected to the Raspberry Pi’s hardware SPI interface.
Four momentary switches hooked up to GPIO pins with pull up resistors and hardware debouncing so you don’t have to worry about it in software.
A 6-pin header for accessing the serial console with a USB BUB or an FTDI cable.
A four pin header for the I2C pins, power and ground for easy connection of I2C sensor boards.
The remaining 10 GPIO pins are broken out in a 10×3 header block with rails for power and ground, for easy wiring of switches or other devices.
An onboard 300mA MCP1802 voltage regulator to provide more power on the 3.3V line (the Raspberry Pi header only provides 50mA on the 3.3V pin).
like my friend just said - the adc chip on the lots-of-pots boards handles everything - there's an object in purr-data that returns individual pot values completely transparently
