- Dave will be giving a talk on trends in hardware innovation at Maker Faire Sydney.
- One example given was board share programs like OSHpark (we had @Laen on show 149) There is also a new Aussie version called breadboardkiller.
- Chris will be doing a talk on KiCad at an event at Supply Frame (sign up here!). He will also be at DEFCON this coming weekend.
- MultiSim from National Instruments is now available via Mouser with a bunch of the parts from their catalog.
- There are lots of online SPICE simulators, but as Mike Engelhardt discussed on show 196, they are based on the open source (but also out of date) Berkeley SPICE engine.
- Chris is attempting to re-work his Wurlitzer 200, discussed back when the show started.

- Dave has been having issues with part sourcing. He has a special Digikey part number for a resistor $6K.
- The job of engineers is to reduce risk in components and designs. Chris thinks it’s better to pay for better parts and offload that risk to the part manufacturer.
- IBM is trying to reduce risk by selling off their chip fab…for negative $1B.
- Radio Shack has planned the closure of a large chunk of its stores…but may not have the money to close them.
- Panasonic is partnering with Tesla to build the Giga factory for batteries.
- Chris was around when Samsung built a new fab in Texas…the logistics of building a huge facility are daunting.
- A new PCB printer called Squink is fundraising on Kickstarter. It is similar to the previous Cartesian Co, but also has Pick & Place capabilities and it dispenses conductive adhesive.
- The TI Fly Buck (the LM5017) is an interesting way to generate isolated power.
- Why aren’t there schematic standards (like coding standards)? Maybe there are for mil spec / ANSI?
- Dave looked at this in his recent vintage power supply teardown, which had some odd conventions on the schematic.
- Chris also had troubles reading the cap values on a his Wurlitzer schematic
Need some help with a legacy schematic…what are these cap denominations? MFD = uF? .001 is .001nF? Or also uF? Gah! pic.twitter.com/puM09k64Tw

Thanks to Eric Horst for the pictures of the resistors.
