That is really cool. So Bourns is making them. I wonder how they would work in a final - have to be QRP...

Planar Transformer

Tim N9PUZ
 

I was reading an announcement about a new POE Hat for the Raspberry Pi computer board. What caught my eye was mention of it using a "planar transformer" in the circuitry instead of a wire wrapped ferrite core. The planar transformer has the windings etched onto a small PC board which is then sandwiched between two pieces of ferrite to form the transformer. I have not seen this technique before.

Here is a link to the article. A picture of the transformer appears at the end.

GA everyone!

Just wanted to put out a quick note regarding Moderator response time. We currently have a couple of people who are unavailable to help out, so our response to owner/moderator questions may be a bit delayed. We still expect to turn around a request within a day but in most cases we like it when we are able to respond in a more timely fashion.

Yes, this would be a wonderful kit to have for future kit building. Count me in. I've also seen some really good suggestions but I don't really even know what was included in the original kit so those in the know will have to be the ones to select, or not, any new features.

Johnny

Thanks for listing the original features, I need go get mine out to find the dummy load (-:

See my list from earlier posting, I still think its got the most usefulness to fill in gaps that builders may lack - lc measurements, precise signal generation with 2 levels etc. Okay to keep its control spartan and less essential to provide a case, okay that may be controversial. Idea is to provide a useful tool set to the builder, I see n5ib made a major contribution.  

Let's see where it goes, but I sense a lower cost instrument will sell more than an exotic.
