It reminded me of Robocop by the way.

What about Han from Enter the Dragon?
X-Men Wolverine

I agree, the demo video was too short.

This has no other details than a series of PCB photos.

I imagine quite a few people would be interested in that "learning shield".
I would add a small sounder to it though. smiley-grin

Is that a battery in the top left corner?

Google Search leads to this.

And this

No USB required?

The question is too general, you need to know what USB device you want to use and start from there.

http://www.circuitsathome.com/products-page/arduino-shields
"The following device classes are currently supported by the shield:

    HID devices, such as keyboards, mice, joysticks, etc.
    game controllers – Sony PS3, Nintendo Wii, Xbox360
    USB to serial converters – FTDI, PL-2303, ACM, as well as certain cell phones and GPS receivers
    ADK-capable Android phones and tables
    Digital cameras – Canon EOS, Powershot, Nikon DSLRs and P&S, as well as generic PTP"

Support for more devices is currently in development.

BTW that page does not display correctly for me in either Firefox or IE unless I make the browser fullscreen, which I vary rarely do. (Unless someone posts a megapixel picture to the forum) smiley-grin

Whats the board (motor, 7 Seg Display etc) you are using in that video, is it a custom or bought one?
53  General Category / General Discussion / Optical Mouse Hack as BArcode Scanner? on: April 30, 2013, 04:09:25 am
I was watching this

and was wondering if it could be used as a cheap method of scanning barcodes.

is it me, or is the 555 timer, bloody great!

If you wanted to impress, detect the radiation levels near to the phone, be sms, ringing.... etc then have a circuit act on that?
Yes, the 555 is an extremely useful IC!

Yup, sound/reads smiley correct to me.

Each PMW pin goes (through a resistor) to the base of a transistor, all emitter connections go to GND, either power or digital, collector goes to one side of the LED strip, other side of the (each) LED strip connects to 12 volt supply.
LED Strip has a common 12v supply (four wires), wire from other side of LED.

if you connect a meter set to resistance (low ohms), you will see that power GND and digital GND are connected together.

In the time its taken to type describe this it would have been quicker to sketch a diagram and scan it. lol

(I will maybe do that later) smiley

GND is connected together, you can use any, all (one leg of) the LDR`s can be connected to the 5v supply, the other 4 wires from the LDR`s (with a resistor to ground)  go to the 4 analogue ports of the arduino.

Here`s a random link to a an LDR circuit
http://www.hobbytronics.co.uk/arduino-tutorial8-nightlight

Duplicate that circuit four times and connect all the supply and GND`s together.

It made me smile!, love it!! lol

Quality build, all the other kids will want one now. smiley

Yup, either sms to some sort of display, (large scrolling LED?) or control a robot chassis from a smart phone (via bluetooth) will have the "wow" factor.
