Holy crap! It works! UNO with photo-resistor. Light readings displayed on 7-segment display. by BloodSoakedDoilies in arduino

For only a few displays (up to 6) you don't need a shift register for this project. I made an example with the three displays I had on hand.

By only having one display on at a time, you can have numbers appear on all three. Each display is only on for 3-4 milliseconds.

Datasheet for displays: link

Please disregard the two red wires on the top/bottom of the Arduino (the one in the middle is still important). They are only there to anchor the board on my breadboard.

Description

I'm using common anode displays and NPN transistors (for a number of reasons, PNP transistors are better but don't make a difference here).

The NPN transistor allows 5V to flow through from the board's 5V pin to whichever display when activated. I'm using one per display.

All of the segment pins are connected to each other for each display and link up to the Arduino (for example, pin 6 on the Arduino is pin 1 / segment E on all of the displays).

I'll upload the wallpaper if someone wants it - it's a relatively large file to upload.

Saw this unfortunate notice watching hulu this morning... by [deleted] in Android

Instructions to do this

For those wondering how to do this, if you have a rooted phone and the latest version of flash, there is a workaround.

First, download the libflashplayer.so file from your phone:

adb pull /data/data/com.adobe.flashplayer/lib/libflashplayer.so

Open this file in a hex editor. On line 005e1390 (or near it for other versions), change "AND 10" to "WIN 10". (The latest version will show "AND 10.2.156.12" before you edit it. You should update your installation before modifying the file if this is not your version. Do NOT change the actual version number - just the word "AND".)

Then, run:

adb push libflashplayer.so /data/data/com.adobe.flashplayer/lib/

Then, open your browser, and go to about:debug (this step may not be necessary in CM7)

Then, go into menu -> settings -> user agent (near bottom) and select Desktop/Windows or Desktop/Mac (probably doesn't matter between these two).

You should now be able to watch hulu videos. I successfully did this on a TMO G2 with CM7 N39.

Note that I'm not responsible if you mis-edit the file or edit the wrong file and damage your phone or your browsing experience.

Edit: as kribby53 pointed out, you can use other apps to help with this - terminal emulators and file browsers will allow you to copy this file to and from your SD Card.

I'm going to be in-game for a while this evening, and I'd love the gatsby, if you're still willing to trade!

From the linked page:

The standard voice chat key ("v" by default in TF2) will still be team-only chat.

Still, this is great news! Thanks!

Okay. When can you trade? PM me with your Steam username and a time so we can trade. I might only be up for another hour.

Unfortunately the caber's already gone (like I said in the post, the first wave went off at 2PM). I've updated the selftext.
