WIRELESS TRAILER TAILLIGHTS
Build a set of wireless taillights that you can use on any trailer.

 

Tired of broken wiring harnesses and bad connections on your trailer lights? Build a set of wireless taillights that you can use on anything you can tow.

 
 
 

WAVES AND PROPAGATION: PART 2 — RADIO HORIZON

Not only hams can take advantage of radio propagation — everybody has a chance to experience some very interesting ways of interacting with the natural world through wireless.

 

In Part 1, we covered a batch of basics on waves and propagation: definitions of terms, and some fundamentals of how waves travel about. Not only hams can take advantage of radio propagation — everybody has a chance to experience some very interesting ways of interacting with the natural world through wireless. Let's put that know-how to work!

 
 
 

TRANSLATIONAL REALITY INTERFACES
Explore one new way of interacting with embedded systems, smart devices, and the Internet of Things by using a translational reality interface.

 

At the forefront of technological development today are smart devices, IoT, simulation, and virtual and augmented reality. Extensions of these technologies — in the form of a translational reality interface — can be used to create interfaces that translate the interaction of one device to the interaction of another remote device. This way, you can complete tasks by simply following your usual activities of daily living, rather than having to take time to learn how to use a new device.

 
 
 
 

ADJUSTABLE ELECTRONIC LOAD USING INCANDESCENT LAMPS
To properly test a power supply, an adjustable load is just the ticket. See how I saved some of my light bulbs from extinction by using them as visual indicators in this adjustable electronic load.

 

An adjustable electronic (power) load is a very handy piece of test equipment in the development of electronics projects. For example, when you're building a power supply, there will come a time when you need to "simulate" a load to see how well your design performs. To properly test a power supply, an adjustable load is just the ticket. See how I saved some of my light bulbs from extinction by using them as visual indicators in this adjustable electronic load.
