DPI and PPI and why it doesn't matter
PPI doesn't matter when you’re producing images for digital display.
Regardless of what you set your PPI to when resizing, that image will always have those same pixel dimensions and filesize.

Intro to charlieplexing | Hackaday
[sixerdoodle] sent us this nice firefly project that serves as an intro to charlieplexing. We’ve mentioned charlieplexing before, in our LED Life post and the Breath Controlled LED candles post. This project is quite simple and focues mainly on how to make a charlieplexed circuit work.

The goal was to create a tiny firefly bottle with SMD LEDs and as few wires as possible. In the video, after the break, it is hard to tell just how small this thing is until we see the battery. There are clear directions and fantastic pictures detailing exactly how to set up a charlieplexed circuit with 6 LEDs.

2006-Jan: Comparison between VA vs. IPS. vs TN: Color and Viewing Angle : pcmasterrace
IPS rules. ASUS has a reputation for QA issues (dead pixels).

But: "Nowadays you can't really just lump all TN panels together. The new 8-bit ones found in displays from ASUS and some other manufacturers have very good colors, acceptable viewing angles and of course very low response times. They're nothing like the 6-bit TNs found in laptop displays and cheap monitors.

I've had the ASUS PG278Q (8-bit TN) since it was released and it has been tremendously good. I tried it side by side with a 30" Dell IPS and the main difference were the viewing angles and gamut. The PG278Q only supports sRGB color space, which is what nearly all content on the web and games is. Came very well calibrated from out of the box too.

It's viewing angles aren't perfect but when sitting in front of it you don't have the massive color shifts you see on crappy laptop displays and monitors. Really only when you stand up or really slouch on your chair you can see issues. Even from the sides it's quite acceptable, none of that color inversion you see on the afore-mentioned shitty displays."

How to Reuse the Old LCD Screen of Your Broken Laptop: 4 Steps
This is a super simple but also very awesome project. You can turn any modern laptop screen into a monitor with the proper driver board. Connecting those two is easy as well. Just plug in the cable and done. But I took it one step further and also build a nice case from acrylic glass. Let's build it!
