Microphone pinouts

Be careful when buying microphones. Microphones can come with 4 most common types. Below is the 3.5mm JACK plug with TRRS pins. It is not standard. https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEinfos99qArDKtuMpq4Q2giaIUTju89G2G1B6CwGqyScfuVg1a7NPb9RnTt9b0vPo-jmBNRq-a-l9reEKzDTAuGBQFyeqgcxTqRwNyU5JR3ahDZUSIWHUXeSVsslll2vmv_jLztYo_lsr7-/s1600/4-pin+3.5mm+headset+connector.png Arimic microphone, https://www.lazada.com.my/arimic-dual-headed-lavalier-lapel-clip-on-omnidirectional-condenser-microphone-mic-cable-length-197ft-for-iphone-ipad-ipod-android-smartphone-for-canon-nikon-dslr-camera-i201786169-s248919059.html?spm=a2o4k.myreviewhistory.0.0.298849fbzPp6x4 It even comes with a TRRS to TRS converter for cameras or PC motherboards or sound cards, including US sound cards.

Polling Using Zoom

Image
This is a failure for me. I cannot login at another location. Many students also need to login using their phones for their microphones and camera.    https://youtu.be/erz4xtQHoVs http://www.bu.edu/engit/files/2020/03/Joerg_Polls.pdf     Use “polling” for interactive teaching or quizzes Zoom has a “Poll” function that allows you to let your students (participants) answer multiple choice questions. You can use this during a class similar to an iClicker to obtain feedback on the students’ understanding and attention.

Using digital cameras as Webcams

Using Sony cameras as a Webcam A5100 Use HDMI to Thunderbolt converter. Use digital zoom to remove skin smoothing. Chris Marquardt 3.61K subscribers The Sony alpha 5100 is a promising camera. It has an APS-C sensor, it's small and affordable and for use as a streaming camera, it provides clean HDMI output. HOWEVER, there are several issues with it that you have to overcome first to use it as a studio camera. Issue 1: supply permanent power. Issue 2: focus jitter with certain 3rd-party lenses. Issue 3: overheating. Issue 4: a firmware bug that makes it near impossible to disable skin smoothing on the HDMI output. It is NOT USEFUL as a vlogging camera due to its overheating issues and the lack of a microphone input. It works great as a stationary studio/streaming camera though. Chris shows how to tame the Sony alpha 5100 for this specific use case. Listen to the podcast episode at https://www.youtube.com/watch?v=mitl6... Amazon.com affili...
