Where can I get LOW voltage LEDs from?Im looking for LEDs, running on about 1.5 to 2 volts. I've tried to get hold of the ones of the Wilesco showmans but had no luckAny ideas????????? |

Maplin, Jim they are usually my first port of call for all things electrical/tv/video etc . . . . | ||||||

maplin are good so are:
www.rswww.co.uk www.cpc.co.uk http://uk.farnell.com What ever happened to the Tandy shops? |

Ill send me grandad down the Maplins tomorrow to get me som. When i get back from school i can work on the secret project

Ahh, I used to spend ages in Tandy looking for DIN sockets to connect a whole manner of Cassette player to hi fi's . . . . Happy days!

I remember the Tandy in Paris Street, was that the one you used to shop in? Halcyon days

When my local Tandy shut it doors for the last time
(It changed to a Carphone warehouse) I purchased there last two radio scanners for £40 each 
I miss that shop

Tandy was a subsidiary of Radio Shack, but they pulled out of the UK (and of continental Europe) because they stopped being profitable. Shame really, I used to mooch around for hours in the early 'eighties when I was a slightly nerdy kid - I co-owned a TRS-80 computer with a friend. I also bought my first ever audio mixer ( 3 mic preamps! Woohoo!) there, so I guess I can blame them for the rest of my life
Maplin's kind of taken over, but they don't have the same charm. The quality of a Maplin store all depends on the staff....we have two here in Cardiff, the small one is brilliant but the large one is woeful. |

Low voltage LED'sYou can'tLED's are LED's and run at about 1.8 volts. You need to decide how many you want and obtain a d.c. voltage supply to match, e.g. 10 LED's needs 18 volts. As you probably won't find an exact match you will need to drop the voltage from a higher value with an in line resistor. Also consider the current required, a single LED will pull about 4 mA. I suspect the 'dynamo' used on the Mamod Showman's incorporates a resistor matched to it's output and the number of LED's on the model. If you are thinking of using a mains transformer I can only suggest you consult a qualified electrician. |
