A New Toy on the N6QW Workbench! 3/29/2020 ~ Your uBitx may contain a critical part of the next generation of Covid 19 Ventilators. 3/30/2020 -- Double Balanced Mixers! I am happy to report that Mouser now carries the ADE-1 Double Balanced Mixers and are available in single lot quantities for about $6 and some change. Nice!  Just checking I went to the SolderSmoke Blog and searched in the Amazon block and typed in Double Balanced Mixers and this is what showed up ($1000) It is a mixer; but probably won't work too well in my design. Guess it is important to be specific. Pete N6QW ******************************** [ I have a sudden interest in 3D Printers. Looking for recommendations firstly, on a good software package as that is probably more important than the machine itself and likely dictate what I buy.

You must have the small white Potatoes, Cabbage Wedges, Carrots and of course the Slab of Corned Beef. Did anyone mention garlic? One year this celebration involved my cooking for 12 guests.  For that dinner I bought a 12 pound slab of Corned Beef from Katz's Delicatessen in New York and had it air shipped to Seattle.

An SDR Radio In a Microcontroller. 3/3/2020 ~ Problem Solved  A cure for Coronavirus? Hey Mikey are you watching this blog?  My Calabrian Grandmother had a bag of old folk remedies that were not many by count; but did cure a variety of illnesses. When I was about 8 years old I got some sort of rash on my arms and despite seeing the doctor it would not go away.  It was summertime and as kids do I was scratching and picking at the scabs --it got worse. By chance we were visiting with "Nonna" and she immediately said: I know how to fix that!  She made a poultice out of beaten eggs and flowers of Sulphur and spread it over the infected area. Next she ripped up an old soft bedsheet and covered the area in what looked like a mummy wrap. Her stern words: leave that on for 24 hours! Boom the next day I removed the wrap and the rash was gone! When I next saw my Grandma, I showed her my arms and she said "good". I then asked what was that stuff. She r
