Boarduino + FTDI Friend

Tuesday, November 2nd, 2010

I’ve been thinking more and more that it’d be useful to explore smaller form factor Arduinos and clones for future space restricted projects – and though there’s plenty to choose from as a start I opted for the Adafruit DC Boarduino (Arduino Clone) Kit (w/ATmega328) – v1.0 for $17.50 and “a tweaked out FTDI FT232RL chip adapter” in the FTDI Friend + extras – v1.0 for $14.75.

My previous experience of other Adafruit kits – such as their Motor/Stepper/Servo Shield – gave me confidence it would be well documented and supported – and this particular combination seemed both cost-effective and flexible… saving $7.50 on the USB version – albeit losing the USB power and USB-serial converter, rx/tx LEDs and the rx/tx 1K series resistors… and $5.25 on the standard USB FTDI TTL-232 cable yet gaining “a little extra – in this case it’s the extra-long headers that you can use to plug it into a breadboard, or a 6-pin extension cable (which will also let you rearrange the wire order). There are also blinkies, 2 red & green LEDs that pulse when serial is sent or received. In a pinch, you can even use it to program AVRs (it’s a bit slow but works!).”

Modular Music Box

Saturday, June 5th, 2010

I’m currently researching how to make and control sound with an Arduino as well as sourcing possible components for the mooted Monomatic Modular Music Box for the “Analogue is the new Digital” exhibition as part of AND Festival in October.

With a total budget of £400 solutions and parts need to be cheap & cheerful – yet do the job…
