Design a Coil for a Specific Inductance

YouTuber [RimstarOrg] shows how to make a DIY inductor for a specific inductance. This is obviously a great skill to learn as sometimes your design may call for a very accurate inductance that may be hard to find otherwise.

It may seem daunting when it comes to making your own inductor you may have a few questions such as: What type of core will I use?, How many turns does my coil need? or How do I calculate these parameters to create the specific inductance I desire? [RimstarOrg] goes through all of This, he even has a handy Inductance calculator  …read more http://pje.fyi/PLp3DC

The Science Behind Boost Converters

[Ludic Science] shows us the basic principles that lie behind the humble boost converter. We all take them for granted, especially when you can make your own boost converter or buy one for only a few dollars, but sometimes it’s good to get back to basics and understand exactly how things work.

The circuit in question is probably as simple as it gets when it comes to a boost converter, and is not really a practical design. However it helps visualize what is going on, and exactly how a boost converter works, using just a few parts, a screw, enameled …read more http://pje.fyi/P4wSW1
