@salbayeng....it's always interesting to hear how other guys started. I used to hitch-hike +/- 10 Km out of town to get 2N3055'S for $ 3.10 rather than pay $5.50 in town. Built guitar amps for my friends with them,,,,
My first job was in a fish and chip shop too, I would peel and chip ~ 2 bags of potatoes (using machines of course!) , gave me enough money to buy my first transistor , a BC108 .
I subsequentially used this to upgrade the burglar alarm at same fish and chip shop , it used a battery and a 12v relay that was always on unless the trip wire was broken. The battery needed monthly replacement, but with a transistor, the standby current was ~ 100 x less.
The same fish and chip shop bought some pinball machines , which I used to fix, then some pong and space invader machines , which I also fixed. Eventually I earned enough to buy my first car ($400 back in 1978).
@Caleb - School teaches you the basics - the 3 Rs if you will - how to Read & wRite and how to do basic aRithmetic (Math to you). Beyond that it's pretty hopeless, my complaint was they specialised far too much in the later stages. For the last two years I wanted to do Math, French and English. They were horrified. "You can't do that, it's mixing Arts and Sciences!". So I did Physics, Chemistry and Biology, and pretty much lost interest, and it was only when I was when I got more or less expelled, 6 weeks before final exams, and got sent to a private college at vast expense to my father, that I decided I better do some work and JUST got through. Schools these days seem to offer a wider array of subjects until you leave school, which I'd have appreciated.
@Kfield so that's where you acquired your razor-sharp business acumen? My Fish-and-Chip shop job was more staid, but (apart from providing me with a few $ for electronics and records) it taught me a lot about how life and businesses worked. I once ventured to suggest to my headmaster that I learned more in my job than I did at his school. He was not impressed. Although it was mostly true, in hindsight I must have been a little sod to teach.....
@davidashton Ha! My first job was scooping ice cream, though I did learn early about what it meant to be an unscrupulous business. We were taught a technique to create a "hollow" scoop of ice cream, so though it looked like a completely scoop, the customer was getting far less. The boss even did spot weighing checks to make sure we weren't actually serving an honest cone.
I didn't realize anyone actually made physical digital harpsichords. I checked around and found the Roland C-30 digital harpsichord, but couldn't find anything similar from Casio. But Casio has been making inroads into the digital piano market in recent years (and their pianos of course offer all sorts of built-in sounds including harpsichord), so I guess it wouldn't be surprising to see the company come out with something more specialized, and probably at a very competitive price point!
There are so many cool electronic instruments being made these days. I was in Red Dog Music, a great instrument store in Edinburgh this week and saw a new line of Casio digital harpsichords and organs. The sounds they made were sweet!
Not sure you'd want to try repairing one of them as a first job though!
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. Are the design challenges the same as with embedded systems, but with a little developer- and IT-skills added in? What do engineers need to know? Rick Merritt talks with two experts about the tools and best options for designing IoT devices in 2016. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
