Loopy (LP8+) is an 8 loops programmable audio switcher controllable either using the built-in foot switches or with MIDI.
I started developing Loopy in the spring of 2020, during the first UK lockdown. It was strongly inspired by the Super8 of BYOC (a discontinued project as far as I know) and aimed to be a super-compact programmable audio switcher built around readily available components.
My main target was to design something that was easy to build for even a newbie DIY-er, with mainstream components and only round holes. At the heart of the project I have put the atmega328(p) micro controller, famous for powering the Arduino UNO, and hence widely available on eBay and many hobbyist stores. I have then decided to use a pair of 74HC595 to expand 3 pins from the uC into 16 pins, enough to control either all the relays + all the status LEDs. The rest of the components are a bunch of transistor, LED and resistors.
I have also uploaded a few videos on YouTube to show how it works in real life. Check the main intro video below and browse my account for more videos:
I am quite happy with the outcome of this project and I decided to develop it further, providing guides, BOM, drilling template and schematic online. Everything is published on the Loopy GitHub Page.
I usually have PCB and microcontrollers available (that I can pre-burnt): ping me if you want one.
Hello David,
That looks like a great project! I would love to have a go at it with a PCB. Can you send me one? How much is it?
Thanks for sharing your work!! 🙂
Ciao. Mi complimento per il tuo lavoro. Sono un amante del Made in Italy artigianale e, per questo motivo, prediligo prodotti come i tuoi. Sono alla ricerca di un pedalino looper molto semplice (tipo Ditto della TC Electronics) per basso; tu ne hai mai prodotti? Avresti qualcosa da consigliarmi? Ti ringrazio molto.
Hi Davide,
Amazing work from the looks of it.?Loopy LP422 seems just like what I’ve been looking for. There are some PCBs up on eBay, but read UK only… Would you be up for arranging a shipment abroad? Send me an email if possible, thanks and best regards.
