Using a small chisel, cut out cavities for all the components at the back of the block. The back side is whichever side looks the worst.I kept all the electrical components (Arduino, Ethernet controller, voltage regulator, and power connector) disconnected...
This is a ray casting graphic demo that runs on a Arduion together with a ssd1306 oled display and some buttons and an analog joystick for movement. This code is based on the great tutorial on ray casting by Lode Vandevenne http://lodev.org/cgtutor/raycasting.htmlAdafruits...
After few tests we had difficulty with the temperature of the driverz A4988. That's why we have now two fan oriented direclty to the drivers. It working great.Here we have the "drawer" below the robot where there are the arduino and raspberry PiOne of...
I had posted previously that I had another failed MOSFET and surmised it was due to excessive start up current of the Currentlimiting halogen globes.I had assumed that the FET had failed due as it was passing current despite the drive signal from the...
The idea behind this project is to create a low cost (~50 €) waveform generator, which is powered by an Arduino, for the hobbyists- students, who need to create basic signals, such as sine, pulse, ramp, but cannot afford to buy a proper WaveGen....
Hello and welcome to the 1st Design Log or DesLog. Every now and then new logs will be uploaded, in order to keep you informed and suggest new ideas for the project.For this first DesLog we will take a look in the Design of the Negative Power Supply...
Here I quickly made a pinout diagram of Ameba Writer and connection to RTL8710 WiFi module for programming. For operation check, one LED is connected between GA4 (D4) and ground. Selecting RTL00 in the board selection is all what we need to set up. (after...
During the preparation for tindie store, I quickly write a demo program, showing JPY/USD currency. This program is greatly based on the source released at this website (I would thank the author), which is written for ESP8266. The source for ESP8266 is...
Spent the last hour writing down the main concept of the Visual Programming Language for the Focus!It's just a simple sketch, but I wanted to share it with you the main raison why I'm building it.Writing down line and lines of code, continually Search...
I already have it working on a breadboard:I'm waiting for the boards to be released from customs :-/The total code size is given at the end of the compilation thanks to the cmake-arduino tool, and it's size is ~886bytes. That was double checked with...
1/5/2017I'm thinking Arduino Yun, and a laser/LED proximity sensor that will detect the black square seen on the perimeter of the spinning meter disk, and transmit that data via my wifi network to my computer in the house, or to a web server so I can...
User Arduino IDE to program the NodeMCUUse MQTT to communicate boiler, remote and controller unit (https://en.wikipedia.org/wiki/MQTT)Boiler and remote units to be a NodeMCU (https://nodemcu.readthedocs.io/en/master/)Remote Units to include an output...
I've always disliked the idea of embedding credentials and addresses into the body of a program or Arduino Sketch - it's just not "best practice". Besides, it means that you need to recompile and reload your program every time you travel to a new location,...
WS2812 LED StringsIf the LEDs are RGB only type, then the Yellow channel is not used, however the addressing remains the same, that is to say, memory is reserved for the Yellow/White channel, even if it is not used.If the LED string (or matrix panel)...
Conway's Game of Life, actually... I dug the display board and the horizontal and vertical driver boards out of a box of junk to revive this long-dormant project. I also realized I never documented the driver boards - I'll have to do that next....
