As the new generation technologies overshadow the old technologies, the way we learn the things also has to change in my opinion.
So if a new generation techie want's to learn how ohm'slaw works, we can create a computer simulation with virtual reality that will give the exact learning experinece as what one can get by opening up the old gadjets and looking at the old discrete circuitry.
So by using the new technology w ecan create much better learning material in my opinion.
The old instruments are going to become scarse as many of them have already been dumped into scrapyards.
It is better to go with the flow than try to swim against it.
When you were a kid, did you take stuff apart just to find out what was inside?
The insides of today's stuff is harder to see without specialized instruments, so we tear apart old analog phones to see the componentry that converts voice to electric current and back again. Then we compare this seemingly larger than life componentry of the 19TH century to today's semiconductor based versions. All things being equal, Ohm's Law is why smartphones work the same way as a candlestick phone. Furthermore, Ohm's Law is fundamental to any circuit design including smartphone RF and Logic circuit designs. So, in the spirit of taking stuff apart that is meaningful, I started telephone workshops gratis to all.
It's 2014 and I look around and see everyone still playing records, except the record player (and all the music that ever was and ever will be) fits inside a peanut shell. While the "shrink" lives up to its name, it does not have the kind of attraction which compels some people to pick up a screwdriver and take a look inside.
I have also noticed that some people can look at the Mona Lisa and think it belongs on a T-Shirt and others look at a recipe for chicken soup and unlock the secrets of the universe. Either way, you need to see it first.
Inside the analog telephones of the art deco era are great learning tools for understanding how Ohm's Law applies. The internal componentry screams out its functionality just by the way it looks. And it's great fun – much better than sliding and poking your finger against plastic and Mylar.
I have been collecting telephones since I was 8 years old starting with a lineman's butt set. My insatiable curiosity with how telephones worked inspired me to become an electrical engineer. My telephone workshops are a great success in recreating the experience.
I believe building a telephone museum dedicated to teaching electric theory using historical devices like the Bell-Berliner-Blake-Edison transmitter is a worthwhile effort. Please let me know what you think.
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
