or even better, for multiple seller instead of only one, try ebay

secondly, don't anyone be taken by this low price - International Warranty doesn't exist. In the US, you will not get service. I hate that BS from Nikon but it is what it is...

That's a pretty huge DAC to be called "micro" :P

Don't want to disappoint you but what you described is known as "development board" and there are thousands of these available ;)

Except of the appearance part since they're just boards..

Hi
This lcd has white leds so it can't have a blue backlight. Maybe it looks a little blue when the lcd is black because some lcds dont display the black color very well especially this which is pretty old.

It might have something to do with the contrast, try playing with that.

I use RS for resistors and they all cost 7 to 10p? So for this resistor/resistor diode setup can I just use a 1k resistor as R1, a 150R as R2, and that diode 1N4148 (http://uk.rs-online.com/web/search/searchBrowseAction.html?method=getProduct&R=6527343) ? http://cgi.ebay.com/1-4W-Metal-Film-Resisto...

What part of it is silly exactly? Presumably just the regulators? As the only other thing in this circuit is the mosfets which are needed and cannot be made simpler. As for cost... can I really save that much with 78l05s costing £0.10 each? That means the other method must cost less than £0.60 to d...

Check if you have cookies enabled.

That pack doesnt have 182k, just 180k. It is only 5% tolorance, so I suppose I could go through testing the actual reisitance on every one of the 100 included to find one that measures 182k... This is silly, I just need ONE 182k 0603. Well if you insist on exactly 182k.... http://cgi.ebay.com/182K-...
