DIY Sensitive Arduino IB METAL DETECTOR (coin from 25cm big object at 100+ cm)
Pavleski Aug 13,2022
  A metal detector is an instrument that detects the presence of metal nearby. This time I will show you how to make a very sensitive, but simple to build "Inductoion Balance" type of metal detector made with the help of Arduino microcontroller and several other components. The Induction Balance principle uses two coils arranged in such a way that there is virtually no inductive pick-up between them. A modulated signal is fed in to one. When metal is brought near, the electromagnetic f...

Making a Digital Light Measuring Meter
Manoj kumar Aug 13,2022
While working on a home automation project on light, the light intensity unit- lux (lumens per square) comes to my mind. Summarizing, while light output is expressed in lumens, light intensity is measured in terms of lumens per square meter or lux. Both the units are different from each other. Let’s have a basic idea about them.Lumens (Lm) are the unit of measurement we use to quantify the amount of visible light the human eye can see. The luminous flux of a particular light source is measured i...

STM32F1 blue pill EByte LoRa E32 E22 E220 shield v1.0
Mischianti Aug 12,2022
Full documentation of the PCBEByte E32 tutorialEByte E22 tutorialEByte E220 tutorialI start using STM32 microcontrollers, and I find they a superior quality. But I need some prototyping board to do my work faster.So here is a prototype board to develop the LoRa application. As usual, I use EByte modules, and this board is fully compatible with E32, E22, and E220.More information, BOM, and description on the relative article on the site.STM32F1 pinoutAs you can see in the pinout diagram, you can ...

Real-time Smoke Detection with AI-based Sensor Fusion
Aug 12,2022
AttentionThe following project is just a DIY project and did not replace certified smoke detectors. As I'm a voluntary firefighter, please keep your home safe and use high-quality certified smoke detectors. The sensor system which is developed by this project is only an addition.BackgroundSmoke detectors save a lot of lives. For example, the number of fire victims fell by more than 48% in France from 1982 to 2012 and 56% in the UK from 1982 to 2013. These reductions can largely be linked to incr...

Smart Basketball Scoreboard
Ávila de Oliveira Aug 08,2022
IntroductionI do basketball training workouts regularly and always track the sections' statistics (number of shots, scores, misses, etc). Track these numbers is kind of boring and hard to accomplish. The smart balls can be used for this but they have some drawbacks:If you want to train with multiple balls you'll need to buy several (expensive) smart balls.The accuracy isn't so good.The durability of the ball.Let's go for it!Versions1.x.xAt the beginning of the project, I used the hardware compon...

SmartWristband
Andrei Florian Aug 07,2022
Abstract Figure 1: The SmartWristband device being worn Monitor patients sent to self-isolate with the coronavirus by collecting their temperature and heart rate through a comfortable wristband and sending this data to the hospital through an interactive dashboard and ensure that they respect the isolation by alerting appropriate authorities if the user leaves their home. I decided to create a solution that would help care for people which have contracted a weak form of the virus....
