This is the effect of my brainstorming about the best board to use for Tote's brains. I initially choose the D1 Mini board, and designed a couple of PCBs to use it. However, I did that late at night, and in the morning I didn't remember that I ordered...
As mentioned, it's time to modernize this design a little bit. So first of all, I added the PCB legs from #D1 Mini Tote, and also added footprints for contact switches at the ends of those legs. Then I switched all parts (except for headers) to SMD,...
It's been quite a long time coming but I've finally got some updates on this project. I've been repeatedly delayed due to a vacation, massive computer failures, waiting for a new computer (then loading all the software etc.) and finally an illness. ...
A gathered all my attempts at a microcontroller-based simple game console, and took a photo:On the far right you can see #Frowney, then there is a bunch of different versions of the #PewPew FeatherWing, in the far left corner there is #D1 Mini X-Pad...
Now after the end of the Kickstarter Campaign last July I have more time to prepare the new Electronics,I love the new ESP32 and its low cost at high quality is perfect for Emme, I´m designing a new PCB board where "click" the ESP32-DevKitC. My...
Today I connected a Feather (Adafruit's HUZZAH + some other niceties) with a giant red joystick. The joystick switches ON-OFF via 4 microswitches rather than proportional movement. That's OK, the motor drivers I've started out deliver an ON-OFF signal...
This device I'm building is not very beginner-friendly. It uses all SMD components, a bare displays screen, needs you to flash the bootloader to a bare chip and compile your own CircuitPython, etc. Quite a bit of work, to be honest. On the other hand,...
The Adafruit Ethernet FeatherWing is the perfect option for permanent installations with wired and reliable internet connections. What we like most about the Ethernet FeatherWing is that it works with the entire Feather board series and can be simply...
After the mixed experience with the gateway based on the Adafruit Feather 32u4 FONA, we came up with a new design. It bases on an Arduino Mega 2560, an Adafruit FONA breakout board, an RTC, and an SD-card reader. The larger memory of the Arduino Mega...
Hello all!I'm not dead and have gotten to pick this project back up after a long time.My current work isn't really ready to post, I'm still getting back into the swing of Arduino stuff again. Currently I'm looking at i2c-based IO expanders to consolidate...
I have spent the whole Sunday re-doing the PCB design, and then adding battery protection, charging and a speaker with amplifier. It looks like this now:And then I realized that the puny SAMD21 is not going to have enough memory to make use of this —...
Recently required a USB keyboard, so I had to update the PCB (v5) in order to work with the nrf52840 Feather Express. The idea was to enable hot-switching from bluetooth to USB automatically when connected via USB, and back to bluetooth...
I've had a few questions about whether this project could be ported to an ESP8266. It turns out the answer is yes:This port is at a very early stage, so I'm not releasing the code just yet. It runs, but loading and saving of settings (and tapes) doesn't...
I've been keeping our 3D printers at work busy. Actually, some "real" work bumped me off our new RAISE3D machine so I finished the last few pieces using our old Makerbot Replicator 2.Here are all the pieces together for the first time.And last...
After playing around with the first Prototype of LoPSy (LoRa Paging System ;-) ) and the first range test went well, I wanted to start with a new hardware revision. The first hardware prototype contained a Nokia display, AI-Thinker Ra-02 433 MHz LoRa...
