 Here you'll find a few of the DIY audio projects I've attempted, completed, or in the progress of building.


JG Squash Score Board 2.0 (code name chipmunk)

I've just finished a squash scoring system for the android.  Scoring is Point a Rally, 5 matches in a set.
I've got plans to add bluetooth connectivity to the app and post results on a score board in realtime.

Instruction;
Android, grab the file and install it.  

Long click on buttons allows you to edit individual names.
Single click increments score, games, etc...
Spinner allow you to choose which side you serve on.

Android Need to work on :-  

-bluetooth connectivity to arduino
-bluetooth commands to send to arduino
-reset current game?
-undo buttons?

Arduino sketch :-
- bluetooth connectivity to the android
- receive bluetooth commands
- update scoreboard with stats

Scoreboard :-
- 2 line display  - 3 characters for players names, 2 spaces,  2 chars for 1st match, 2 spaces, 2nd match, etc...
- should all fit nicely on a 2x 20 line display



JG AUDIO Remote 3.0  (code name squirrel)

Here is my audiophile remote control for your audio projects.  
Arduino sketch and the android apk files will be at the bottom of the page.

Instructions:
Android, grab the file and install it.  

TAB "Sources"
Click selects each source, long click edits the source.

Bluetooth commands it sends are:  btconnect - when connected
b1, b2, b3, b4 - inputs 1 to 4

TAB "Attenuator"
The buttons send the position of the attenuator from 1 to 128, MUTE is 0.

Arduino, grab the file and upload it onto your arduino.
You'll need at least (to start) an arduino and a bluetooth module.

You can monitor the serial output of the arduino, to verify which bluetooth commands it's receiving.

Check the arduino sketch on which pins to wire up. 


Free, unless you'd like to donate to my squirrel / bird feeder fund.



I'd like to thank Ian @ BTInterfaces for his support.



The latest and greatest video...
An arduino, bluetooth module, 8 relays, and btinterface running on my android phone...

YouTube Video


I'm working on a few android apps that will control a few audio control using bluetooth and an arduino module.
These apps were built using basic4android...

First app is a stepped attenuator. I'll be controlling a twisted pear joshua tree with this.

This app allow you to select 1 of 4 sources. I'll be switching relays on and off with this.
You can edit and rename your source (by holding the button down)

Eventually I'll integrate these two apps together.
