The final update design has been partially assembled and a USB C connector had been used in place of the micro USB connector. The tiny 0.49" OLED display has also been fitted and all wiring has been done. Will be powering up the TinyPICO NANO next to...
The PCB arrived from JCLPCB. Arduino Nano and sound card from Adafruit also now here. It's a simple circuit -- just a couple of motor controllers and some voltage convertors which could have been easily done with a perf-board, but I think having a real...
It's alive! Everything is wired and almost all mounted in the case. I'm testing the software, and once that checks out, I will (try to) make everything look pretty inside the case. I am currently running in atomic mode--solely based on the Rubidium 1...
Been going down the road of building the remote and trying to fit everything on an Arduino Pro mini 3.3v 8Mhz. It's not been going well. I can fit all the libraries I need, set everything up for communicating, and establish a loop,...
Just a quick update today...Node 0 has now been built and programmed, picture to follow shortly. It is comprised of an Arduino nano and a NRF24L01 with a SMA Antenna. This will be permanently connected and powered by the server (currently a PC).My Raspberry...
Summary: I am trying to replace the malloc() implementation so as to get an idea of memory usage patterns. Along the way, I discovered some interesting things about the internals of libc, eLua, FreeRTOS, and some features of the linker. Deets:...
I just realized recently I made a silly mistake when I designed this project. I've been so used to working with the standalone ATMega and always needing a 5V regulator. When I decided to use an Arduino Nano for this project I overlooked the fact that...
In addition to the rest of the ideas I have for communication I want to add one more thing; a flexible software serial header.This is to serve as an extra port for communication and control of a slave unit's Nano. This port will mirror everything sent...
Just ordered some components from US suppliers, so they should get here fast:10 x 3Pin 10cm Servo Extension Lead Wire for Futaba RC Connector Cable LB10Pcs 2.54mm Pitch 0.1 1x15 15 Pin 15p Female Dupont Header Arduino Nano HeadersAnd then when those...
I inadvertently confirmed today that if you plug in a cell backwards you indeed do need to buy yourself a new Nano. :) Still works, but voltage calibration is way off and seems to bleed between channels. I messed up the ADC for...
The first thing I did was checking if the inputs were correctly connected to the Arduino and if it could read them properly. So I installed the Arduino IDE on the Jetson Nano (could have done that on a separate computer) and wrote a sketch to read all...
I improved linker just now and added ability to link static libraries. It is pretty simple, these static libraries are normal object files generated by assembler. Linker now have new argument for specifying path where to look for such a files. So, when...
Here are some photos showing the project at various stages... This is the CardKB keyboard next to an AA battery for scale. Basically it is the same size as a standard credit card, and fits perfectly edge-to-edge in the Altoids tin. The first time I actually...
Hello, This being the first log and the project is ongoing for some time, I'll put here all the works until now. As we know the internet is full of toaster reflows, I've gone through most of them for inspiration. But none of them were matching my components,...
I've now got a fully working prototype of the eMBee ONE! It is running on breadboards with the following components: Arduino Nano clone1.54 inch OLED display connected via SPICardKB keyboard connected via I2C24LC256 external EEPROM connected via I2C...
