Podcast appearances and mentions of pat hensley

In this episode we meet Pat Hensley, W5WTH, a prolific designer and project builder.  Pat has made several intersting radio and non-radio related electronic projects and he features them on his blog site WhiskeyTangoHotel.Com Some of Pat's projects are very useful and some are just plain fun.  Many projects are a blend of hardware (Arduinos, Raspberry Pis, etc) and software (c, Python, etc).  Pat publishes all of his source code for us all to learn from.  If you want to be inspired to build your first project you have come to the right place. 

This week I've finished a dishcloth and my vacation socks.  I've been working on two other pairs of socks, a plain vanilla pair as well as the Kephart Prong Socks by Pat Hensley. I've still got the Dust of Snow Wrap by Helen Stewart on my needles and I cast on the Night Shift by Andrea Mowry. I've done some indoor gardening and some shopping for supplies while hoping that the corona virus fades quickly.

Preventing burnout, finding the right colleagues, communication, the struggle with perfection... these topics are just some of the encouragements that 30-year special education teacher-turned-college-professor Pat Hensley has for teachers everywhere. This South Carolina teacher has a message of hope and encouragement from her experience in education that will help all of us get motivated this Monday! www.coolcatteacher.com/e481 Pat Hensley - Bio as Submitted Pat taught students with special needs in public school for over thirty years.

Podcast Notes Popping in last weeks audio was probably due to a cheap USB cable. Stephen and Parker recorded last week on a laptop with a USB powered mic preamp that has less then stellar power filtering and performance. Stephen is continuing work on his automatic brewing rig. Has a motorized ball valve to control the flow rate for proper mashing and cooling rates. Parker found the correct IC that is inside the Jeep radio. Part number TDA7340S. It is a 100% direct match to the pinout of the IC inside the radio. He found it by looking at ST's catalog of Audio and Radio ICs from that time period. To switch Audio sources to an external source, Parker is going to hack into the TDA7340's external effects loop. See Figure 1. The signal will probably have a DC offset since the IC is on a single power rail of ~9.4V. DC offset should be around 4.5V. The Bluetooth adapter will need to have a DC offset to match. ICs to switch the audio signals will either be a NJM2520D or a MAX4544CPA+. Shout out to Pat Hensley from Tektronix. Came by the shop earlier this week to get a tour of the fab and show off some Tektronix goodies. Got to play with a Tektronix RSA306B USB Spectrum Analyzer. Which was really awesome. Real time over USB. Interface is scriptable with Python. Will be looking at getting one for pre-compliance testing. Attacking air gapped computers using the cooling fans. Basically a piece of malware tweaks the PWM on the fans inside the computer to transmit data audibly. Make your own nuclear battery. Using Tritium keychains and some solar cells to produce power. The battery produces 1.6 volts at 800 nano amps or 1.23 microwatts. Special thanks to whixr over at Tymkrs for the intro and outro!
