Saw this advert - shower head with LEDs to illuminate the water stream, coulour indicates temperature. <http://www.coolproductsusa.com/shop/led-shower-head-with-temperature-sensor/?fb_action_ids=3921615035746&fb_action_types=og.likes&fb_source=hovercard&fb_aggregation_id=246965925417366> Supposedly without batteries or external power. "No batteries and external power supply needed. The color change tells you the water temperature. Bright LED light. Approved by CE & RoHS certificates. Electricity is generated by hydraulic mechanism." I wonder what mecahnism they use to generate the power & if it really is as bright as the marketing pictures depict! No doubt they will make a few dollars out of it!

They're out of stock! The faucet unit is only $6.99, for that price
I'd tear it apart just to see how it works.
I expect someone to explain it. ;-)

That's wrong! Blue is the hottest color in the universe. Red flame - hot Blue flame - HOTTER Artsy fartsy wise, however, both blue and green are considered "cool" colors. English power cord... The BROWN wire is always 'the hot'. It is easy to remember if one just remembers hot and cold.

Well, remove the restrictor, and you get that back. So, the generator can be set (designed) to spool up until the drop matches what a proper, restricted head would deliver. They would always be red with me. My showers are 125 degrees.

My showers are 125 degrees. EEs should be legally exempt from having to use low-flow shower heads. We get all our best ideas in a good hot shower. -- John Larkin Highland Technology Inc www.highlandtechnology.com jlarkin at highlandtechnology dot com Precision electronic instrumentation Picosecond-resolution Digital Delay and Pulse generators Custom timing and laser controllers Photonics and fiberoptic TTL data links VME analog, thermocouple, LVDT, synchro, tachometer Multichannel arbitrary waveform generators

Found a video here, doesn't look as bright as in the advert: http://www.youtube.com/watch?v=gG1ZDpPA5l4
