Stephen

• MacroAmp Rev 2: Sponsored by Mouser Electronics
  • Schematic is complete
  • Only grounds left to run and to do a review
  • Completely rethought design
    • Simulated power supplies
    • uTracer data gathering for everything
    • Gain calcs - one or two nutube?
    • Coarse and fine volume controls
    • PCB mounted Tube sockets
    • Terminal blocks for easy assembly

R.F.O.

• Non-destructive banana ripeness determination using a neural network-based electronic nose
  • Follow up from last weeks discussion with Nick Chelyapov
  • Accuracy of 90.3% was reached using an “electronic nose”
  • Sensors are sensitive to ethylene (the ripening hormone in climacteric fruit, such as apples, peaches, bananas, etc.)
• Buzzfeed for Electronics?
  • Need More Energy Storage? Just Hit 'Print'
  • Lords call for evidence on impact of digital tech
  • Organic Semiconductors: One Transistor for All Purposes
  • Renewable Energy Won't Make Bitcoin 'Green,' but Tweaking Its Mining Mechanism Might
  • Powering Devices -- With a Desk Lamp?
• Beyond 1 and 0: Engineers boost potential for creating successor to shrinking transistors
  • A multi-value logic transistor based on zinc oxide
  • Zinc oxide combined to form a composite nanolayer, which is then incorporated with layers of other materials in a superlattice
