No problem, would be interesting to see how you get on with the smart glass, as it seems to be a new product.

Could you not use an LCD screen with out the Backlight?

This is not stuff to mess with unless you *really* know what you are doing.

The way I would do it would be to have the arduino drive a smaller relay which controlled a mains contactor relay

Again, do not attempt this unless you really know how to wire high current circuits.
367  Using Arduino / Motors, Mechanics, and Power / Re: Looking for relay that can power pool pump?? on: August 26, 2012, 07:26:16 pm
Soild state relays have no contacts to wear out due to arcing when switching an inductive load like a motor.

Yes, I noticed that, unusual to connect the diode across the transistor to sort the back emf that way.

Simple (on/off) driver circuit, scroll to bottom of page.

Depends on the type of punch bag you have, hanging or freestanding?

Whatever the sensor is, it and its wiring will have to be pretty robust!

Use a blinkM clone (with suitable driver circuit to power each LED string)

372  Using Arduino / Project Guidance / Re: Capacitive touch glass on: August 25, 2012, 04:42:05 pm
These solutions still preclude the transparency of the blocks being preserved from both sides. Perhaps I could embed the sensors on the sides of the blocks and angles them towards the center of either side.

P.S. I am new to this forum, how are you guys inserting drawings. Is there a tool for that on the posting UI or are you just exporting an image from something else?
Yup, mount them on the sides.
For images, I use http://imgur.com/, you just drag and drop your images onto the webpage, upload and it will give you the proper format {BBCode (message boards & forums)] link (look for the "img" tags) to insert in forums like this.

Makes me think of Runway lights... smiley

Jet tries to land on his driveway... lol

Anyway... have a look at this:

Mount the receiver at the back of the block mount the infrared leds at the front.

The receiver is "looking" through the glass block, so any variation in illumination can be detected.

Its possible to drill glass, but you would have to careful if you want to mount the LEDs that way.

Another way would be to mount the LEDs at the front in Plexiglas so that it edge lit.
