Hi All
I was just doing a bit of research today (may be of Interest to Barri and Ian
) hunting around for the Led Trifield meter.Which was featured on the Ghost whisperer episode 16 season 4.I found a company in USA who has the Trifield meters.I emailed the company and got 2 different prices from them not including the postage to the UK.In total the meter came to approximately £120 that was approximately £100 for the meter then shipping costs when they eventually emailed me back with full cost.
Well i hunted around a bit longer and found the same kit which you would have to build yourself.I emailed the company to see what it came with.
The kit comprises of the casing and printed circuit board and all the components and circuit diagram.The kit with postage is just under £60 depending on exchange rates.
The components needs to be soldered.
The kit is from Ramsey Electronics they are based in USA however there are links worldwide but the kits are not available in UK.
http://www.ramseyelectronics.com/cgi-bin/commerce.exe?preadd=action&key=TFM3CRamsey Electronics also sell these on ebay and the shipping cost is not displayed the cost they quoted me to ship is $29.75 so i ordered one.
I was a City Guilds qualified Electronics engineer many years ago in my passed life.So i can assemble these kits with in a few hours if that .
I believe with a Slight modification and you can or may be able to incorporate sound circuit.
Hope you find this of use and money saving.
