Re: Secondary Memory Interface

great project. Thanks for sharing it. It's a shame there is not a lot of information about the SMI.

Re: Underwater ROV

Wireless or rather most RF doesn't work very well submersed in water which is why all ROV's are tethered via a cable to the surface.

Re: Raspberry Pi as a Bass Pedal/ RSP

I'm not too familiar with fx's for bass pedals but the basic idea is the same for both guitar and bass: use an ADC to capture the audio signal, then use software to manipulate it in some fashion, then use a DAC to generate new audio sound based on the manipulated audio. Using an audio codec with som...

Re: Raspberry Pi as a Bass Pedal/ RSP

There's been a few Pi & Arduino based fx pedals

Re: Sharp LQ092B5DW01 (960x160pixel TFT module) meets RPi3

Sorry to resurrect an old thread but does any one know where the Sharp LCD LQ092B5DW01 is stocked?

Pollin had some, but they are out of stock:

Re: A Pi using an external Zilog Z80 chip

I can't help thinking that you would have a much nicer time of it by getting hold of an actual Z80 board. For example the RC2014 Mini - Single Board Z80 Computer Kit: https://www.tindie.com/products/Semachthemonkey/rc2014-mini-single-board-z80-computer-kit/ I saw that board at the Bay Area Maker Fa...

Re: RPi Synthesizer Project

@TonyD - Thanks for the link to the Rpi UART MIDI setup - very interesting. I assume you built some sort of MIDI IN to GPIO interface. Yeah. I've built a few for the RPi over the last few years.

Re: RPi Synthesizer Project

@Jum & @IanS Both synth projects look great. Over the years I've built a number of different serial MIDI interfaces for the Rpi for using a MIDI keyboard so I'm really looking forward to seeing how both your projects develop Here's my last attempt: https://zuzebox.wordpress.com/2015/12/13/settin...
