Fourth Stream Summary
Log from Keyboard FeatherWing
We're done with the routing!On yesterday's stream (that went on for 5h, but the Feather was done around hour 4), I finished routing the board and putting all the finishing touches like the silkscreen. The board is now ready to order!

Revision 1 Design
Log from Ultra Low Power Feather Development Board
Since the ATSAML21 is such a close relative to the ATSAMD21, this layout is based somewhat on Adafruit's Feather M0 line. However, it also incorporates solar cells for energy harvesting, an accelerometer, and a barometer. Initial specifications are as...

IoT and background radiation monitoring.
Log from Cosmic Array
Each element of the Cosmic Array is essentially a complete cosmic ray (muon) detector and radiation (gamma) monitor. So it can not only be used in a light and sound display but also be used to measure both cosmic ray flux and background radiation. So...

First of all: this the first time I used an Adafruit product and while it costs more comporaed to other sites I am glad I did purchase it there for the followin reasons:It worksIt a very good quality and the design is goodall is open source/visible sourcego...

Creating a Case for the Logger
Log from Voltage and Current Logger
Adafruit does a great job of making their 3D designs available in Fusion 360 archive format. That made it easy for me to modify their TFT FeatherWing Design. Specifically, I made four changes: removed the on-off slide switch on the left sideadded...

Octosonar FeatherWing 0.0.1 uploaded to OSHPark
Log from OctoSonar FeatherWing
Initial design done. I originally went with one sensor connector block in an extension on each end, but then realized if used as an under-wing the wires would clash with the USB, so I packed them both into an extension at the right hand end. This made...

Ordered Boards for Production
Log from OctoSonar FeatherWing
Ordering 100 boards from PCBWay, as someone bought out my entire stock of Octosonars. Tweaked the design as follows: upped all the 6 mil tracks to 8 mil - the OSHpark boards failed on the first pass. I'm not sure if this is related, but there was...

Design phase finished! (I think.)
Log from SoundWing Audio I/O Board
I took some time last night to complete the board's design. After a last-ditch effort to see if there was some way to include I2C on this board (short answer: no flippin' way), I moved things around so the mike output could go to any of A1-A5 with a...

Log from RoverWing - Robotics Controller Board
The day you have all been waiting for is finally here! The RoverWing campaign is finally launching on the Crowd Supply platform, after weeks of hard work and preparations to ensure that everyone who wants one gets a RoverWing as soon as possible. A quick...

Assembled
Log from Handheld Wing
The PCBs arrived a while ago, but I was still waiting for the SMD pin headers. Those arrived today, so I assembled it. Using those headers for the first time, I'm actually quite happy with them. The only problem I can see is that the default Fritzing...

Designing the PCB
Log from Tougher INA3221 Power Monitor
I wanted to keep the design 2-layer, and with some insignificant shortcuts, I kept it at two layers. I have tried to avoid large currents to pass around INA3221 to prevent ground bouncing, so I added some cutouts in the ground. Cutouts are...

Initial DVI working with HDMI Monitor
Log from Homebrew Computer & OS from modern MCUs
Over the past few days, I've been playing with an Adafruit Feather RP2040 DVI to test adding support for external HDMI monitors. Yesterday, I built out a newer, cleaner version of the graphical shell using Adafruit's modified picodvi library and got...

Hardware
Log from Wave Clock
I started by buying a Feather M0 Express from Adafruit when it was brand new, enticed by the then new-ish CircuitPython because I knew a little Python from a college. The feather sat around for almost 6 months while I researched components,...
