I even modified this circuit to use as a voltmeter in one of my cars.
Maybe calling it a hack isn’t correct, but it is usefull anyway. Maybe you need another category called “old but fun crap”.

Prehaps, the LM3915 it’s very very old, and i think most of we know how to drive it.

If you’ll go this way, you’ve to get a domain like instructable-a-day.com or ad-a-day.com

Juan Aguilar, i don’t know you, but i know that YOU are getting hackaday down and down each day…

Theres been some intersting stuff and some teribly out of place stuff. Lets hope this is just teething, and we’ll level out some where half decent.
This post falls into the out of place category. Its like going up to bunch Head Chefs and saying “Hay check out this egg I boiled!”

VU meters have a fairly specific dynamic response.

“the day you think you know everything about anything is the day when you stop learning”

i never would hire anybody with such arrogance.

I remember playing with that chip 30 years ago, when I was in high school.

This isn’t instructables.com! This isn’t I-am-a-electronics-idiot.com

This is hackaday! posts some gorram hacks already!

Save the drama for rendezvous with rama.

The guy even entered it into the Robot contest on Instructables… hell, I’m going to copy some circuit verbatim from the datasheet and enter it into contests to win prizes against those who put some real blood, sweat, and tears into a custom design.

I’ve already been to Engadget and Gizmodo, I don’t need to read the same articles a third time. How about showing us some hacks ?

Here is a quick write-up:
