CDC Endorsed use of Ivermectin for Afghan Refugees

Horowitz: CDC Endorsed use of Ivermectin for Afghan Refugees Looking at 2019 CDC guidance, one has to wonder if one of the reasons why there is such a run on ivermectin is because our own government is using it. And no, not for horses, but for refugees. Yet these same government agencies are runnin...

Re: A TL431-Based Turn On Delay With Mute and Power Fail Detection

Before I set this circuit aside I wanted to post some oscillograms of the turn-on and turn-off behavior. The blue trace is the +15V rail. The red trace is the relay coil voltage which is active low. The trigger level was set to +13.5V. The power supply was switched using its AC On/Off switch. This ...

Who’s Really Being Hospitalized?

Who’s Really Being Hospitalized? Authored by Jennifer Margulis via The Epoch Times (emphasis ours), “I’m not going to arm wrestle with the administration about where to put you,” Dr. C., a highly skilled gastroenterologist, said gently to my friend who was in bed in a triage room in the ER. “We jus...

Re: Texar Prism clone prototype

Jeff sent me a blinky light demo of the protoype : Video: https://proaudiodesignforum.com/content/Ortelligent_Texar_Prism_TPC-100_Demo.mp4 There's no direct audio but nice visual action and a beautiful front panel. https://proaudiodesignforum.com/images/png/Ortelligent_Texar_Prism_TPC-100_Demo_Thum...

Tempco Resistors

I had a chance to play with the 3900 ppm tempco resistors from KOA Speer. The response time is really fast. These are 5% resistors but the 25°C value was almost dead on. https://proaudiodesignforum.com/images/jpg/KOA_Speer_Tempco_1K_3900ppm_Resistor_LT1_4LT52R102J3900.jpg KOA Speer Tempco 1K 3900 pp...
