Arduinome phase 1: getting the parts (and IV)

This is the last section of this phase, I got all the parts for my Arduinome!!!

I went to my local electronic shop in Madrid and got:
10x10KOhm resistors (I got normal resistors instead of a resistor network, since they did not have resistor networks in stock)
2xMale connectors for Arduino shields

That was 8 euros total.

I am only missing some other random stuff (connectors, cables, screws and nuts...), but all this should be enough to get me started.

Summarizing, the total cost so far is:

€68.93 - SparkFun Buttons and Button pads (including S&H to california, not spain)
€25 - Arduino board
€9.6 - Green LEDs
€8 - other components

These numbers are based on current exchange ratio.

Arduinome phase 1: getting the parts (III)

The ultrabright green LEDs for my arduinome arrived last week from Hong Kong:

I bought them through eBay to an eBay store named “Amigo-of-China”. The transaction was perfect; the items were shipped very quickly and arrived in perfect condition. Will definitely buy from him if I need LEDs again, I have now an “Amigo” in Hong Kong!!!.

These are the LEDs:

And this is how it looks like with the SparkFun buttons:

Check out also this video I made with the SparkFun buttons. The keypad shortcuts the LEDs pins switching the LED on and off:

I need to think what to do with the remaining 36 LEDs and the 100 resistors provided. Suggestions are welcome.

On the arduinome project, the parts I am still missing are:
- Diodes
- 74165
- 74164
- Resistor network
- Screws and nuts

Is Roland watching me?

As I have already stated in blog posts, forums posts and a youtube video:


Well, I have been heard... Introducing the new Roland AX-Synth Keytar (or Shoulder Synthesizer, as they call it... I wonder if keytar is a registered trademark that roland can not use):

I do not particulary like it and the reasons are:
  1. It is a synth, not a controller, which will probably make it super-expensive for an amateur musician (who actually does not know how to play keyboard very well) like me
  2. It reminds me to the keytar Jordan Rudess plays sometimes:

I know, I know... that one is even worst...

However I am happy about it, other brands seem to follow what Roland does, so we should probably be seeing more keytars (or shoulder Synthesizers... pfff...) soon.

The end of MusicThing

Sad news from MusicThing came yesterday, Tom Whitwell is too busy with his "real-life" job to be able to continue writting his blog.

It will be missed.

All the best in your new job, Tom
