Bat Synth 2
A simplification of Bat Synth to increase replay quality, This requires a 384kHz USB-C DAC, about £15 from Amazon, to replay audio from computer or phone.
Hand soldering of this will be trivial, no need to order a solder stencil - there's only the headphone jack and the LTK5128 module.
The back of the main PCB exposes bare pads for +5V and GND, simply chop the end off a USB charging cable, strip the wires and solder to the PCB, then power from a USB power bank. Audio comes in on a 3.5mm jack.
3D printed frame attaches base plate to main PCB, and is quoted as about £1.50 from Midlands3D in HP MJF, probably the same or slightly less from PCBWay.
