The idea was quite simple. Buy a linear actuator from OpenBuilds with a stepper motor, attach a camera on top of it, two tripods below, assemble a control box with some Arduino-compatible, WiFi-enabled board and write an Android application that would...
The Technogym manual indicates that the RF HR receiver outputs a 5V and 30 ms pulse for each heart beat. A ESP32 with abilities will be the perfect µc. It's a easy job for it to read the incoming HR value and to output a pulse. Since the ESP32 works...
You can find the schematic ready to edit and go on EasyEDA here. Source code for the Arduino sketch is attached and below. Note that it uses the TimerOne library to provide higher-resolution Timer1 frequency control for the Pulse Width Modulation to...
HARDWAREESP-32: The ESP32 makes it easy to use the Arduino IDE and the Arduino Wire Language for IoT applications. This ESp32 IoT Module combines Wi-Fi, Bluetooth, and Bluetooth BLE for a variety of diverse applications. This module comes fully-equipped...
The project is wholly composed by off the shelf components: ESP-01ArduinoDS3231 RTCNeoPixels5V to 3V3 regulator The ESP-01 creates a hotspot and serves a page with a form and a button The Make it Glow button maskes the ESP01 send the string typed ...
What if I told you it was possible to SAFELY use ANY SmartPhone as a robot brain? On any smartphone with a browser, load a freely hosted github.com webpage with Javascript that blinks areas on the screen to send motor commands to an e.g. Arduino....
Today we present the FlameWheel Robot assembly tutorial and quick-start guide! It is rather difficult to assemble this robot without guidance. Feel free to refer to my introductory tutorial today.Flamewheel (A 2WD Remote Control Robot) is part of our...
The story so far... Update: Row scanning working.Known/working: Building and loading via JTAG new firmware into the main FPGA. This firmware is starting from scratch, we don't understand much yet about the default Barco firmware, although we've dumped...
Why Did We Build This? "Prevention is better than cure" is one of the effective measures to prevent the spreading of COVID-19 and to protect mankind. Many researchers and doctors are working on medication and vaccination for corona. COVID-19 spreads...
Project Overview Video for Hackaday Prize 2023: The End Result The Plan In principle it is simple: by connecting different combinations of binary value resistors in parallel, and assuming a constant input voltage, we can consume any arbitrary amount...
The work by others to port Arduino BASIC to the Smart Response-XE device was of interest, but I wanted a few enhancements to extend battery life (auto shutdown) and I wanted an easier way to do math on the console rather than typing "PRINT" everytime...
3-11-2024 See these two 2011 Liliputing and TechCrunch articles, which were partly the inspiration for this project: https://liliputing.com/pixel-qi-suggests-low-power-tablets-could-be-powered-by-1w-solar-panels/(6-3-11) https://techcrunch.com/2011/06/04/first-solar-powered-laptop/ (6-4-11)...
Background If you have been following Hackaday for a while, you will have seen on numerous occasions the KENBAK-1, regarded by many as the first commercial personal computer. Ten years ago Mark Wilson introduced KENBAK-uino, a reproduction...
In this project, we will build a 2.4GHz Wlan scanner using the nRF24L01 radio board. In this project, the output delivers all the interference and information in the scanned area in the form of ASCII codes. In the project of making this scanner,...
Techniques ReviewWe are going to consider only time series analysis in this section. There are reviews of "complexity measures" (Feldman and Crutchfield 1998, Daw, et.al. 2002). Kuusela, et.al. (2002) compare the results of ten different complexity measures...
