Clone PI-W Atmega8 (Arduino) Metal Detector short Review
Pavleski Sep 24,2022
   Quite by chance these days I got in my hands a "Clone PI W" metal detector module, so I decided to immediately do a small review and compare it with my previously made DIY Metal Detectors.  At first glance, the module is solidly made, the elements are precisely placed and well soldered. The price is less than $50, including postage. In this case, it is an SMD version of this detector, and you can find the same metal detector made with standard components made accordi...

Arduino Based Table Tennis Robot V1 DIY
Hernando Sep 23,2022
About: This project is about a TTR(Table Tennis Robot) made at home with cardboard and wood, using some electronics and Arduino. I found various videos and get inspired because the interactivity of this robot, the Table Tennis sport and the call to action this machine produce is awesome.I am happy for this TTR DIY, and really gave me a lot of fun. Even I was looking for a lot of mechanics I tried to use arduino and electronics and one App, developed with MIT APP Inventor, as the Basis of Design....

Robot Arm to implement CV projects
Hernando Sep 23,2022
StoryFour years ago I was looking for a good robot arm, this year I have time and decided to replicate the Dejan Project.The STL files are perfect to 3D print locally, usin PLA and the default setting, the software need small adaptations, and the APP need some understanding to work and be modified properly.The project has been full of fun and challenges.I recommend it a lot.CVI need to design a new robot arm for a CV project, and this Robot Arm is a perfect Path to move ahead in the right way wi...

TOKEN MACHINE AND QUEUE MANAGEMENT SYSTEM FOR HOSPITALS
mohdazhar Sep 22,2022
ABSTRACTPatient wait times have a strong influence on patient satisfaction levels. A common scenario in front of clinics, and hospitals are people standing in long queues. These people cannot do any other activity until they are served. In order to save time when standing in long queues, it is better to issue a token to each individual and call them when required. One can be occupied otherwise until that individual‘s token no is displayed or announced. Thereby reducing patient waiting times and ...

Pocket RGB Light | Arduino & WS2812B
Lutfi Sep 20,2022
In this article "How to Controls WS2812B Using ESP-01 Arduino (ESP8266)". I made a custom module for the WS2812B LED using the ESP-01. With this module I can make various creations using the WS2812B LED. Among them are RGB LED Strip, RGB LED Animation and RGB Matrix. And in this article I will create an RGB Light Pocket using the WS2812B LED Matrix. I will use this LED for photography lighting. What I hope is, this LED can give a unique impression from the photos I take.Component and Material Co...

Android Vinyl Action Figure Automation
Ávila de Oliveira Sep 20,2022
IntroductionI had two Android characters like the one shown following and I thought: Is it possible to attach some mini motors and automate it? Spoiler alert: Yes, It is possible!Let's go for it!The brand new Android Vinyl Action FigureAndroid Figure setupFirst, I had to carefully open the little toy to make room for the three motors and the two RGB LEDs. One motor drives his head, and the other two motors drive his arms and LEDs to his eyes. At first, I thought it would be impossible, due to th...

Speed controller for a 3D-printed high torque strain wave gearbox - Harmonic drive
Sep 19,2022
DESCRIPTIONI was fascinated by this type of gearbox and always wanted to make one. This type of gearbox is one of the most used in industrial robots. This type of gearbox only has a single reduction (in this case 2 because of the belt reduction) with a very high reduction ratio. Because of the single stage reduction there's almost no tolerance/play between input and output shaft. Conventional gearboxes use more gears to achieve the same reduction ratio, the tolerances between the gears add up re...
