Ferrite beads

By AP, 

            
I ordered some ferrite beads for a RF circulator project I currently work on but these might also be very handy for the SWR bridge project. These are extremely efficient for RF supression, or at least this is what they say.

A cold war era reel-to-reel
By AP,  
This old reel-to-reel was the joy of my teenager days, Back in eighties I was listening to VOA and Radio Kuweit and I was recording mostly on east-german OR-WO tapes (that were quite decent) because the BASF and Agfa were in shortage. Western music reached the black market usually by pilots that were operating civil […]


                            

                                
                                                                    
                            

                        

                    

                

                        

                    

                        

                            
Boards for prototypes
By AP,  
For low frequency projects, a fast way to prototype is using a bare PCB and scratch some dividers that allow “manhattan” style prototyping. I am especially very fond of this prototyping technique and I believe that PCB design should be avoided in the early stages of prototyping. Jim Williams was an artist in such designs.

This is a beacon project started by my friend YO5VAE. He faced some issues while programming of the Si4463-based module and I thought I might give a hand. I resoldered the entire project on an empty Arduino shield to allow expansion of the project with some additional modules. Below are some pics, but probably the […]

I am pretty pleased by the outcome of my commercial endeavours on eBay. Purchasing seems to be a pleasure; until now — with just one exception — I was spared from any nasty experiences. After several small items that I ordered in part for my curiosity to evaluate speed and quality of shipments from chinese suppliers, I […]

I love fridge magnets. We love fridge magnets (my wife likes them too). This is how our fridge looks like: But we also love beer. And we have a large collection of beer bottle caps and coasters. So I thought to combine these and make the caps stick to the refrigerator. Now, what you need […]

…and not only software (maybe). OK, to keep things short, I got tired by limitations of my Saleae logic analyzer, especially on the software side so I decided to build one. This is my new project: a DIY logic analyzer that I will hopefully use to better extent in my other projects. First results promising. […]
