Misc Stuff - Singe Side Power Supply, by Fred Vobbe, W8HDU. [ PDF] - OpAmps for Everyone. A really good doc from Texas Instruments on OpAmps.
NOTE 1: 7mDXC LITE User Guide Mistake. There is no “ double eye”, only an Upper Spreader Plate ( triple top plate). I will amend this shortly.
NOTE 2: 10m ABV Classic now has new hole spacings on driven ( and the nylon plates) for equidistant spaced 3, 4 or 6 e updated manual.
