EP#393: Recyclable PCBs, EOL Design, Cold Cuts
Parker and Stephen discuss Infineon’s use of recyclable PCBs from Jiva Materials to create a soluboard, a recyclable and biodegradable PCB substrate, and its ecological and efficiency implications, an examination of the new Arduino Uno, which replaces the ATMEGA328P with two new models, Minima and Wifi, plus a CNC update and an extended meditation on saw blades and what they can and cannot actually cut.
More on these topics:
Infineon uses recyclable PCBs from Jiva Materials
- The fibers are natural and have a lower impact than traditional glass based fibers.
- 7.1kg and the carbon footprint of one square meter of standard FR-4 PCB is estimated to be 17.7kg.
- Does anyone really know what “carbon footprint” means?
- The non-toxic polymer that binds the fibers dissolves when immersed in hot water, leaving only compostable organic material. The polymer in the water can be disposed of in normal waste water.
- 7.1kg and the carbon footprint of one square meter of standard FR-4 PCB is estimated to be 17.7kg.
- A 60% waste reduction
- Electronic devices can last FOREVER
- Bad reviews vs. pollution vs. boiling the boards vs. useless promo items
Jiva Materials
- Compatibility with current PCB Assembly processes
- Repair, don’t replace!
- Hoping for some Jiva experimentation
- Board Mould
- Mmmm, PCB soup…
- Making puzzle badges but also, BOIL YOUR BADGE
- But is the PCB Spaceworthy?
New Arduino Uno:
- The ATMEGA328P is no more! Replaced with a 32-bit ARM Cortex M4.
- Comes in two flavors:
- Minima which looks to just be the MCU and supporting hardware.
- WiFi which has 2.4Ghz capabilities and a LED Matrix?
- The Minima has a proper SWD debug connector where the WiFi version does not?
- Gripes with Arduino
- Super crisp silkscreening
- USB and HID Support
- Raspberry Pie has bit the bullet
Once Year Since the CNC Project Began: An Update
- We are cutting!
- Getting garbage plywood and the state of Baltic Birch
- Building the interior of the box truck
- Always find a local source
- Using the wrong blade can feel so right
- SAW (blades)
- Metal and wood and cold cuts
- WARNING: PODCAST DANGER ZONE AHEAD
