Looking forward to your progress with this

Ive wanted a hex Pickup guitar with optical ADAT interface for years

Quote
On the other hand..
the digital version of the project I have settled on using 4 x PCM1803 for A/D conversion and PCM1770 for D/A conversion.
Been looking at packetizing the data and seem to have come up with something so similar to ADAT format, that I might as well do it as ADAT format.
8ch x 24bit 48kHz NRZI encoding in a 256bit packet with reserved proprietary bits (for the GK controls).
the Raw digital audio would be at a rate just over 12Mbps, with NRZI encoding, it would be around 6Mbps.
This leaves a spare audio channel for either a second guitar in/out or a headset microphone.
If I put an optical I/O in the project, it could double as an 8 track ADAT interface for recording from the guitar, or ADAT playback into the receiver unit.
It may also be possible to utilise the system also as a wireless ADAT interface.
Have some WiFi modules on order capable of up to 72Mbps data rate.

So i know I'm getting ahead of the process but what's the form factor of the receiver? are we talking half rack, or 1u rack mount?

Haven't given the form factor much thought yet, so far I just envisage a rectangular box that sits on the floor.

I personally have a dislike for plastic rack unit enclosures, and metal ones add significantly to the price (no idea on that either at this stage).
Of the 3 concurrent design projects, I have now eliminated one, so the remaining two will be

1.) a general consumer short range (50~100 mtrs) WiFi digital model - probably as a compact sized receiver.

2.) a semi pro 900MHz (possibly insertable R.F. modules to suit specific countries/radio bands 170MHz to 1GHz) long range (~1000 mtrs) hybrid model - probably rack mounted receiver.

Been looking at various WiFi RF modules, and I came across this new to the market one..
http://www.digikey.com/catalog/en/partgroup/wysbhvgxg/60682?mpart=WYSBHVGXG&vendor=587

Data Rate:433.3Mbps
•Frequency:2.4GHz, 5GHz
•Mounting Type:Surface Mount
•Operating Temperature:-30°C ~ 85°C
•Package / Case:Module
•Packaging:Tape & Reel (TR)

•Power - Output:14dBm
•Protocol:802.11a/b/g/n, Bluetooth v4.2
•RF Family/Standard:Bluetooth, WiFi
•Sensitivity:-87dBm
•Serial Interfaces:SPI
•Voltage - Supply:3.3V

then looked up it's data sheet
http://www.yuden.co.jp/wireless_module/document/datareport2/en/TY_WLAN_WYSBHVGXG_DataReport_V1.1_20160331E.pdf

and damn... the thing is only 10mm square, how do they make them so small?

I understand maybe half of this at best, and I'm already drooling all over myself  :o! I am SO looking forward to this project maturing. Also wondering what incredible thing might happen when you and Robert put your heads together ;-).

Don't know how it is in the rest of the world, but here in Europe (at least in Germany) the 2.4 GHz band is hopelessly overloaded, so I am happy to see the 5 GHz option being considered.

Best, Kenny
Take what you need, put back a bit more, leave the place behind you better than it was before :-)

How are you doing on this project, Gumtown? Haven't seen any updates lately. Is the project on hold? Need some encouragement...

Had a series of events which had slowed me down recently,
a work project in my regular day time job requiring long days, and a few set backs with the project.
Been playing with PIC micro MX32 chips and the MPLABX with Harmony framework, as I need something ultra fast to encode and decode 8 audio streams.
After many hours of frustration, I discovered that out of the 5 pack of PIC micro chips, only 1 worked, although all 5 have been plugged into the same board.
Must have been a bad batch?

With the Hybrid version, I have been playing around with various compander designs, and trying to locate a source of digital noise, which I suspect is from the OLED display.

So I am still working on the project, but with a few recent setbacks, there has been nothing new to report (in good news) ... so far..
Still doing the R & D stuff.

I know how it feels...the day job is a burdon 8)
However, watch out for industrial espionage. Foreign intelligence might sneak around your area just a few days before Xmas with a portable antenna, metal detector and Geiger counter, searching for signs of wireless activity. However I'm afraid I'm not sure what you do to trespassers in your country. You offer hailshots or coffee...? ;D
Got more gear than I need...and I like it!

Coffee or beer in this case..  ;D

Any update on this from gumtown yet?

I sure everyone has seen these videos...i have contacted the guy, but never received a reply...may be a hoax?

The Wireless GK hurdles will be

* added latency

* less dynamic range  / higher noise floor for COSM Guitar modeling

Don't give up! You have another taker here! I think there's a magnet embedded in my gk cable with its brother under my fc300 volume pedal. EVERY... SINGLE.... TIME!
