Podcast Notes

• Continuing on the Jeep Bluetooth radio hack, Parker designed the audio voltage bias switcher board. It will adjust the Pk-Pk voltage and DC offset of the Bluetooth adapter to what the radio expects. Ordered it through MacroFab. See Figure 1 and 2.
• Parker also started designing an amplifier for Spooky Pinball. Based on the  TDA7387 which is a 4 x 41 W quad bridge car radio amplifier. Designing it to be as inexpensive but as LOUD as possible. Currently down to $15.91 an assembled board in QTY 500. Need a beefy heatsink and powersupply to handle it.
• Stephen has been working on his Resistor of Death (name to be decided). By combining resistors in series and parallel, Stephen will be able to make a large high tolerance resistor. The best tolerance resistor on mouser is 0.005%. Can we get better than that with 1% resistors? N = 1/0.005 = 200 resistors FOR EACH PARALLEL/SERIES COMBO Total resistors = 40,000.
• Sorry RFO section got cut off due to a problem in the software recording. :(

Special thanks to whixr over at Tymkrs for the intro and outro!
