you need a soldering iron. Hewlett Packard issued an application note re this topic back when they introduced their pocket calculators.
I am amazed all LED instruments esp those used in the light aren't issued this way.
Maybe someone would like to start a business making such things. I would if I wasn't already busy designing a trolling motor.

Kirk,
good to know. Aren't you talking about component level design? Is it practical to talk about pulsing the display of a meter that is already built as in this project "helm instrumentation project". I know the subject has wondered because of my foolishness but still aren't you talking component level?

There are low current techniques you can use with LED displays. The eye sees peak brightness not average so you can pulse the LED. 20 ma on 20% of the time is far brighter than 4 ma continuously.-Kirk

Nice Mike,
I also have been looking into a way to get feedback from my bank. I admit my needs are different than a boater needs, but I like your system. I am thinking of a dedicated E-book reader that receives the information via WiFi from an arduino board set to monitor my system locations of interest. The right reader will give me a sun safe and easy to read display. My past experience with LED displays is they are a little power hungry. The Problem with LCD displays are sun will black them out and destroy them with time. The idea of electric paper type display may well overcome these problems. I just need to find the right tablet that I can do some Java programming on (modify it's intended design), and build an apt. I suppose I could use a smart phone and keep up with the data remotely but that is more involved than I have desire for.

Thanks Mike,
Quite interesting.
If you do your post as Rich-Text the addresses come out as links, eliminating the need to copy and paste.
