Hello everyone!
Here’s my attempt at making a portable synthesizer:
Specs:
- SBC: Orange Pi PC+
- Keyboard: M-Audio KeyRig 49(Scored for a few bucks
) - Power: Asus 10050mAh(Lasts quite a bit, did not measure it but in the range of 4-6 hours)
- Screen: ili9341+XPT2046(No touch unfortunately, the allwinner H3 on the orange pi supports a single slave/spi bus)
- Encoders: generic breakout boards from china interfaced through a stm32 sending commands over UART
- Soundcard: Aliexpress speciality $1
- Single 3.5mm jack output
- Built-in wifi with external SMA antenna
Paint job is not great, I know, I’m not a painter myself
Upcoming: Embedded stereo speakers with cabinets
