MAX78000FTHR FaceID Demo

Posted by ralphjy Top Member May 27, 2021
My experience with the MAX78000 ecosystem so far has been really frustrating.  Like other design frameworks that I've encountered recently, the Maxim setup uses an Eclipse IDE on top of CMake tools.  I've found these frameworks extremely difficult to use, primarily I think because I'm using them in a Windows environment and also the fact that these frameworks evolve quickly (much more quickly than the documentation) so that things are constantly breaking.  I guess that's the price ...
The nice thing about using a Feather compatible footprint is that all of the FeatherWing accessories are available for use.  It would be great to integrate a small display with the MAX78000FTHR to create a portable smart camera.  A stacking display can't be used because it would block the camera and stacking displays don't have very high resolution or appropriate aspect ratio.   Adafruit makes a couple of nice TFT FeatherWings that would mount the MAX78000FTHR on the back which i ...
I recently started using an Adafruit FunHouse with CircuitPython Adafruit FunHouse and did a quick project for Mother's Day and my wife's birthday Adafruit FunHouse - Happy Mother's Day .  When I did the Mother's Day project I had wanted to have pictures and sound, but did not get that part finished in time.  I discovered later that the compiled slideshow library adafruit_slideshow.mpy was available for CircuitPython v6, I had just missed seeing it.   So, I decided to give it a t ...
I just received a MAX78000FTHR  which is Maxim's new low-power artificial intelligence development board.  It's a pretty feature packed board in the Adafruit Feather form factor for $30 https://www.newark.com/maxim-integrated-products/max78000fthr/dev-board-32bit-arm-cortex-m4f/dp/09AJ3133?st=max78000 .   I'm really interested in how well the low power CNN accelerator works and seeing how low power it actually is.  The board has video and audio capability with a VGA came ...

QT Py RP2040

Posted by ralphjy Top Member May 14, 2021
Adafruit now has an RP2040 version of their QT Py:  Adafruit QT Py RP2040 .   Another nice compact design with USB-C, a Stemma QT connector plus 8MB of SPI Flash and a NeoPixel LED.  It is interesting that they kept the castellated pads, but because the RP2040 and Flash memory are on the underside of the board - you would need to put a cutout in the host PCB to attach it.     I have a couple of Xiao accessory boards from Seeed that I want to use with with this board ...

I've become a project...

Posted by ralphjy Top Member May 12, 2021
A few weeks ago after completing the 2 week waiting period after my second Pfizer Covid vaccination, I went to donate blood for the first time since the pandemic lockdowns started.  To my surprise, I failed the donor screen due to an irregular heartbeat.  Surprising only because I've donated over 10 gallons of blood without any issues.  Anyway, I went to the doctor for a checkup and an EKG and now I'm doing a 24 hour test with a Holter ECG monitor.     It's interestin ...
As I had feared, I did not get a lot of opportunity to work on my project for Mother's Day and my wife's birthday.  I did manage to build something basic that I could show my wife.   I printed a modular segment to hold a PIR sensor and a USB power bank.  This segment is attached to the back of the FunHouse facade that I had printed earlier Adafruit FunHouse .  This allows the FunHouse to be portable, but it isn't aesthetically pleasing.  In the future, I'll design a LiP ...
