Code

How to Build a Leak Detector with Text Message Notification
This guide demonstrates how to build a leak detector that sends text message notifications. It sends alerts if water from a burst pipe or backed up drain is sensed. The guide is intended for anyone interested in Python 3, Raspberry Pi, Secure Shell (SSH), Shell, crontab, command line, linux, and open source related projects. The text notification service (Twilio) works in the United States. It may or may not work in other countries. Windows was used though Linux and Mac should work too. Read more...

3D Printing

How to Create and Print 3D Objects
These 3D printing examples include: a laptop phone holder, a lock latch for an electrical panel, and a tool for adjusting door latch springs. Parts like these can be quickly designed, built, and delivered to your door by using this method:
1) Create a free account and part at onshape.com .
2) Right click on the "Part" in the lower left corner. Export it as an STL format. Select millimeters as the unit of length.
3) Import the part to the 3D printing service company at: shapeways.com .
Alternatively, check your local library which may have a 3D printer available at an even lower rate. That's how I was able to print the brown latch for just $1. The earlier white and flimsy version cost about $7 on Shapeways.
4) Pick the material of your choice, shipping method, etc.
