This post is here because the pdf files in the documentation section are a very informative and enlightening about how a Hobby-DIY Enthusiast can learn by Practical Electronics. Peter and Kitsrus – Affordable Kits I have been seeing these files for many years, they give an indication of what generates ideas and inspiration for the [...]
I Invented a Switch Plug in my school days but venture capitalists were not invented yet. From Creations This idea struck me when i used to visit flea markets to collect gramophones and calling bells and some chemistry lab flasks and test-tubes too. Electronics had not come to me yet and not much in the [...]
Amplify uV from Sensors to mV levels for A/D Converters, which in turn may drive a display or connect to a uC means MicroController. Now there is unicode I can write μC. Now we will break into small html lesson, paste this as html or put it in the source… μ .. you get this… [...]
A Low cost A/D with a Potential of 5KV Isolation from Computing elements by use of Normal/Special Opto-Couplers. This can give better resolution and accuracy than a 8 bit A/D. may be close to 10 bit A/D. Added advantage is that you can optically isolate the inputs. Suppose your temperature sensor touches a heating element [...]
