After my hardware switch to Unexpected Maker's Feather S2, Sparkfun's MCP6900, and Adafruit motor board (I need to update my BOM) - I waited throughout the Circuit Python 6.x series to see if they would fix the fact that the Sparkfun wouldn't work with...
I am making an M&M dispenser for a friend, and used this board in it. A Feather M4 Express was used for control (overpowered by why not??), and the motor was a 5V 28BYJ-48 I got on Amazon for $2. Works great! First draft, 07/26/20...
I've been moving along nicely and have pretty much all of the network functionality up and running.I started to work on the Music Maker functionality and soon ran into a problem: Insufficient RAM and flash on the Feather 32u4.So I've switched my build...
I have my cheapo mini usb host shield (max3421e) connected up to a 3.3v 328p feather board. the arduino code translates the USB HID data to ps2 data for the fpga system - giving usb mouse and keyboard via a powered hub. I think I may have space for usb...
DAYProject Logs Week 11MONFinally succeeded in calculating distance between two gps points today! it's the little things that make the difference, in programming, there are no big things, just a bunch of little ones that add up or don't. In other project...
I recently made some updates to the project the simplified the code running on the feather, and made the services running on the pi zero more resilient to failure. Updates are here and I wrote more about what I changed here.
Revision 1 is finished! Rev 1 consists of a basic layout of all necessary components, with some problems. Due to space constraints of the Feather footprint, there are some signal lines that really shouldn't be where they currently are. Future revisions...
Adafruit Feather Logger We started using an Adafruit Feather Adalogger to use and test our code before getting the parts that are running late. Temporary Arduino Dimensions Arduino dimensions for the practice one while we wait for ours to come....
Yesterday, I spent my morning designing the 2nd version of my control board. I decided on a couple of things. I would use the Feather Standard of boards because to make a feather wing for it only costs me 9 dollars, and I can use the Feather M0 Adalogger...
RAD2 has onboard datalogging capabilities, so it can be used as a very low power device. However, it is often convenient to access data in real-time. As RAD2 is Feather compatible, it can be used with any WIFI, BLE or other wireless Feather. ...
Revision 2 has been designed! After some very helpful feedback from Michael, who is an expert in u-blox implementation, and has been made a co-contributor to this project!Modifications made to this Revision include:Fixed unconnected grounds around the...
Here be the source code!Next steps: after being happy with the small Xiao BLE for the initial prototype phase (will it work? Of course!), I decided to use the Adafruit nrf528xx feather because of:I already have a couple of LCD feathers. It will make...
Here are some more details about the whole concept of this board.The board will be the size of a standard FeatherWing shield -- same as the Adafruit Feather boards, and of course it will plug into those boards. It should work with any of the Feather...
While I'm waiting for the delivery of the VL53L0X sensor boards from AliExpress, I thought I'd take a whack at understanding the PCB requirements for a first prototype of the halo. The Arduino Feather M0 Express that I got from Adafruit has been working...
I have carefully analyzed all of the qualified projects, and I'm ready to announce the winners of the main prize (the OpenMV camera board) and the prizes sponsored by Adafruit Industries (the five Adafruit HUZZAH Feather boards). The prizes sponsored...
