While studying electrical engineering, I learned early on that electricity doesn’t really work like everyone thinks. Here are four things you probably didn’t know about electric current.
Choosing the Right Solder
The choice of the right type of solder for electronics projects and PCB prototyping is actually an easy one despite there being hundreds of options. There are three things you need to look at:
Introduction to IPC-A-610
An early Christmas gift arrived at Stratify Labs today: the latest revision of the IPC-A-610 standard. At Stratify Labs, we like to stay up to date with the most current industry guidelines for building and designing electronic assemblies. PCB design plays a big part in ensuring a smooth transition from prototyping to production and long term reliability.
ADC Signal Conditioning
Analog signals typically are not ADC friendly, but they can be with some relatively simple circuitry such as a low pass filter and amplifier. The goal is to have the analog signal cover the entire range of the ADC. For example, if your input goes from 0V to 1V and your ADC measures from 0V to 3V, you will need to amplify the input to take full advantage of the ADC. Voltage scaling seems easy enough but you also need to make sure the frequencies you are measuring are low enough for your sample rate which is where filtering comes in.
Analyzing Op Amps
Operational amplifiers, or op-amps as they are affectionately known, are very useful when designing embedded systems and relatively easy-to-use. If you know just a few of the basics, you can design and analyze op-amps like a boss.
