Spent this weekend building a remote controlled car with a live camera feed with a Raspberry Pi doing the communication and brains duty. Pretty nice real time movement control and camera pan/tilt control through websockets with a live stream feeding back to any browser directly from the car through mjpg-streamer
(PS: Video is at the bottom of the post. Browser/video on TV courtesy ChromeCast. Casted my Nexus 5 screen to the TV simultaneously while controlling the car :) )
Dangerous is a mind which is left grounded at home for days. Being stuck at home and having a few pieces of joy around made me do this over the weekend.
Ingredients:
An old Toy RC car broken out of shape by my 4 year old
DAGU Mini Driver
Screw Driver/Batteries/Tape/Glue/Rubber bands/Old gift cards
Half an hour of coding
Output:
A car that runs automatically making 8 shape on the floor (More like random fractals due to the wheels having no grip)
My brother, Amit Goel, has founded a startup “Patterbuzz” which is aiming to disrupt the digital publishing marketplace. Read on for details about it in his words. I can assure you that you don’t want to miss out on this whether you are a publisher or a consumer :)

Exchange Security Bypass Xposed Mode for Nexus 4/5/7 and other AOSP based devices (Android 4.3 / 4.4)
Update: This has now been tested to work successfully on all stock or nearly stock JellyBean (4.3) and KitKat (4.4) ROMs on Nexus 4 / Nexus 5 / Nexus 7. Other AOSP ROMs like CM11 should work as well.
This mod should be used along with Xposed ( http://forum.xda-developers.com/showthread.php?t=1574401 ). Xposed is this awesome framework developed by rovo89 which allows you to carry out mods to your device without changing any files (well except one “app_process” as part of the xposed installer). Moreover, once you install xposed, you don’t need root after that for any mods.
This script is the result of a weekend’s hacking to get my TV to display incoming calls/texts which I miss invariably because the phone is buried under a sofa or in a different room. Earlier I had done this using my Odroid U2 and Tasker/AutoRemote but this was limiting as this meant that I could see the notifications only when I was watching something through the Odroid. Samsung TVs, which are DLNA enabled, also include a hidden service called “Message Box” which can display different information on the TV natively irrespective of which display mode/input mode you are in.
