I bought some relay boards from Bulgaria for some tweaks & lash ups & was very pleased with the items, w/o dredging thought the feedback think this was the seller http://stores.ebay.co.uk/DAEStore seems to all sort of interesting relays...

That stuff looks pretty good!

How did you get on with the bits you bought H?

usb/ serial thing relasing a door off a pc & normal relay driven off a prem

Interesting stuff there good find H

I've bought from that Bulgarian seller too - good stuff.

Seems Bulgaria and not the Womble from Wimbledon has learnt from the past and having a little take over of its own !!!

I've used these before, when I had to drop to 5V for old Paxton readers..http://cpc.farnell.com/xp-power/il1205s/converter-dc-dc-2w-5v/dp/PW02214

They look useful but not suitable here as only 400mA max.

Have used 3rd one down, actually seem quite well built. Its powering a USB powered micro wifi access point off a Scanny 95. Obviously just cut off USB if you don't want it!

 

Looks like the listings have changed.

 

I meant this one to save confusion - http://www.ebay.co.uk/itm/DC-12V-to-5V-3A-15W-Step-down-Converter-Regulator-female-Panel-mount-USB-for-car-/161006629218?pt=UK_BOI_Electrical_Test_Measurement_Equipment_ET&hash=item257cbe3162

 

I'm sure I have seen CE and e marked versions available too, mines just for a test lashup so not bothered. Plus whether the markings

are genuine or just spare ink is also open to intepretation I know.

For a little project i need a device to make 5v from 12 - 14v dc.

i know i could build a regulator and heatsink etc but id rather buy something. Any suggestions. Load is between 0.5 and 1 amp

iirc Maplins flog a simple kit, you could get a plug in stabilised adapter for about £14 from there, if sensitive kit stick a 10watt zenor diode across it to clamp any over voltage variance or spikes.

Made this from a cigarette lighter usb converter.
