AES encryption on an ATiny

Posted on February 23, 2015 by robertwilkie

The author managed to get AES running on an ATiny for building a secure channel for a doorbell.  This is neat and I am impressed that it was done (in assembly no less). http://hackaday.com/2015/02/20/aes-cmac-on-an-attiny85/

Make your own scrub stick from PVC pipe

I like this build.  Instead of scrubbing your shower down just by a pad, the author makes a holder for the pad out of PVC so you can get more leverage out of it. http://www.instructables.com/id/PVC-Tiles-Clean-Pad/

Spin an old harddrive with a Soleniod

Posted on February 23, 2015 by robertwilkie

I got a kick out of this since it reminds me of steam power engines.  The author basically re-uses most of the hardrive and just attaches a bar from the heads (motor driver) to the platters. http://hackaday.com/2015/02/21/spin-up-an-old-hard-drive-with-a-solenoid-motor/

From the King of Random.  He basically uses packing tape on paper to get the toner to tranfer over and then irons that onto the board.  This looks like a good way to do this.  And much easier than some … Continue reading →

One really fancy doorbell

Posted on February 23, 2015 by robertwilkie

The author took a Raspberry Pi and basically added the camera module, display, etc to the doorbell to keep an eye on things.  I like how it calls your phone when enabled. http://hackaday.com/2015/02/22/raspberry-pi-doorbell-is-fully-featured/

OK this is a funny way to recharge a cell phone

Posted on February 23, 2015 by robertwilkie

This is a funny video where the author hacks a car battery to charge a cell phone.  I don’t think I would do this unless I absoluted needed to do so. http://hackaday.com/2015/02/22/macgyver-jedi-knights-ammo-stockpiles-and-candy-crush/

Posted on February 20, 2015 by robertwilkie

Nice blog post on how to get and decode traffic on a vending machine to repurpose it.  Beats the alternative of just replacing all the boards and building your own.  I stumbled on this post by accident while digging for … Continue reading →

Hack a snow shovel

Posted on February 20, 2015 by robertwilkie

Basically the hack is to extend the lenght of the shovel.  This way you get more leverage to shovel the snow with.  Its a good idea and this winter…this maybe this weekends project. http://www.instructables.com/id/A-Better-Snow-Shovel/
