Okay. So its not completely tambourine functionality (I need to add “Shake”), but certainly this feels like a realistic controller for the skin part. I do want to Midifit the Conga at some point, but this makes a neat sunday project.
Some help from Alf..
1 Tambourine (Tunisia Branding completely optional.. Mother in law’s holiday present for me !)
Piezo sensor ( Maplins, 89 pence)
5.1 V Zener
I thought i would add this to my existing MIDI transport/Controller project, just because I didnt really want to take all apart.
Ill post details later
Okay Im getting into this. Its absolutely a doddle.
Decided at 6.30 I would create a (very simple) controller to FFWD,REV,STOP AND PLAY my Reason Transport..
The Arduino is extremely versatile and quite easily lets me output serial data driven directly from the pins. It looks like I should maybe opto-isolate if i’m using Midi IN but seeing as most of my experiments are going to be controller based, then Midi out is just peachy.
4 Tactile Push to make Buttons, each generate a midi note, output via my midi cable (Dont forget the 220 Ohm resistor on the +5v Lead Kids..)
* To send MIDI, attach a MIDI out jack (female DIN-5) to Arduino.
* DIN-5 pinout is:
pin 2 – Gnd
pin 4 – 220 ohm resistor to +5V
pin 5 – Arduino D1 (TX)
* all other pins – unconnected
Hacked around with the code at..http://todbot.com/arduino/sketches/midi_drum_kit/midi_drum_kit.pde
(Basically removed the piezo code for now. Until the sensors arrive 😉
Added extra button code
Loaded up Reason
Set up my secondary midi port (Named Arduino)
Used the Learn function to assign the notes to actions.. eg Transport in this case.
Voila. I now have a remote Reason Transport controller…..
Philips have this technology called ambilight. that basically lights the rear of the tv, supposedly enhancing the effect of Movies etc.. Well I thought as I have the arduino, id give it a go..
Stage one.. I found a program (Sketch) and design for a RGB moodlight in the book that accompanies the starter kit. It uses PWM (Pulse width modulation) to light 3 LEDS at varying brightness (IE RGB Values).
That worked just fine…
Stage 2: Again on the starter kit there is an application to accept serial RGB values.. This works from the serial monitor in the Arduino app.. Input R255,G255,255 gives a theoretical white light..
Right now part 3..
I found some VB code that outputs the RGB value at the cursor point to RGB values. That worked also
Finally, I used the serial control to send to the device.. Very rough. I am NOT a developer. But it worked..
Now i have my theoretical ambilight. Im going to experiment with positions of my mouse to see which ones offer the best effect (Center/Top corner/Top Middle Etc.. Ill keep you posted.
Not bad for a couple of hours messing about..
Hah World of warcraft.. Not sure if you can see the LEDs the same color as my enchants 🙂
Day 1 – Planning – What should I build?
I thought i would just list a few items I plan to build. Maybe it wont pan out like this, but here are the plans.
- Semicircular midi controller, with monome style buttons.
- A environment controller for world of warcraft. maybe something simple like a red light when I get hit, but maybe something more complex 🙂
- A “Philips ambilight” replacement
- New and strange ways to interact with music – its not all about black and white keys 🙂
Lets see how it goes..
