Risky Components and Hardware Innovation - Slipshod Shack Shutdown

Listen Later

1 hour 12 minutes

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of online SPICE simulators, but as Mike Engelhardt discussed on show 196, they are based on the open source (but also out of date) Berkeley SPICE engine.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

Thanks to Eric Horst for the pictures of the resistors.
