I wanted to know which access point my RPi is connected to and its IP address, and so i wrote a little clever program that lets me know just that.  This python program looks up its SSID and IP address then sends you message on twitter. You can use crontab to run this program on start up.

How to set up start and stop time for a YouTube Video
Problem: You would like to start and stop at a specific time within a youtube video Solution: We will modify the url to youtube to start and stop youtube video.
Step 1: Grab video url 
-Here is my example: https://www.youtube.com/watch?v=GwTXwJg6_VE
Step 2: Modify video url to start and stop time

Step 3: Add your start and end time, but wait it has to be in seconds;
-I want to start the video at 1:07 and end at 4:19 -Lets convert this to seconds:  -Next step maybe elementary math: Warning! -Start time: 1:07 min --> (1 min)*(60 sec) + 7 sec = 67 seconds -End time: 4:19 min --> (4 min)*(60 sec) + 19 sec = 259 second
Step 4: Modify url
-Take the url from step 2--> https://www.youtube.com/v/GwTXwJg6_VE
at the end you will append [?start=67&end=259]
-The result will be https://www.yout…

How to make custom hood struts Step 1: Buy material
Step 2: Cut and drill The large piece you see in the picture will go on the hood where two bolts hold the hood to the hinges. The smaller piece will be bolted to the fender. You will need 2x for both pieces if you are doing both sides. 



 Step 3: Install very easy to install, just bolt the large bracket to the hood and hinge holes, use the bolts already there. The small bracket, you bolt down to the front fender, there is a bolt already there for the fender. You can use the same bolt. Now clip in the gas shock and check for clearance.
