Jon, count me in for what ever help is needed…it’s a great idea.toggle quoted messageShow quoted text
Let’s take the 10 amp linear power supply as an example. It can be built in teachable and functional segments with students predicting, then testing the performance of each segment as the build proceeds:
- AC input and step down transformer; AC safety, proper fuse selection, input over voltage protection. Test design output versus actual out put with VOM.
- Rectifier options, selection. and wave versus full wave, center tap versus. Add/build rectifier to AC section. Again observe DC output with VOM and Oscilloscope.
Without making this message too long then move on to DC filter section, voltage regulator, then pass transistor drivers and pass transistors, then under and over voltage sections, metering options. Again the idea is to pause, teach and test as one builds.
My vision is to design and produce a full featured board which allows all of this, but also allows optional features, like metering, to be bypassed should the student elect to do so.
