I2C IO card for ESP-12E I2c Base Card
MakerIoT2020 Jul 28,2022
I2C IO Card for ESP-12E I2C Base CardThe I2C IO Card for ESP-12E I2C Base Card is another expander card for the ESP-12E I2C Base Card Project. This PCB is an address-selectable I2C module with two relays and six (6) GPIO pins, all driven from a single PCF8574 running at 3v. The relays are optically isolated, and generous mains isolation cutouts were provided to reduce the possibility of mains voltage tracking. A jumper to enable/disable the i2c pullup-resistors is also provided on the PCB.The re...

Machine Vision Trip WIre | Switch App when Motion Detected
SimonX Jul 28,2022
IntroductionWanna slack off abit but scared to be busted? Here is the all-in-one wireless tripwire that help you automatically switch your computor program when motion is detected! Best of all, it uses MicroPython to program OpenMV so you can even add some "whitelist" using face recognition, and it also use RTL8722DM_MINI as the Bluetooth Keyboard, so you can even trigger a custom script upon motion detected~??DemoProject DetailsA hearty combination of "Machine Vision" and "Bluetooth HID" functi...

Atmega 328P based PWM controller Card
MakerIoT2020 Jul 27,2022
ATMega 328P Based PWM controller CardAs part of my recent ESP-12E I2C Base Board project, I designed an ATMega 328P Based PWM controller card, that can be used as an add-on card with the existing project, or standalone as a custom Arduino Nano compatible development board.What is on the PCB?The PWM controller card contains standard Arduino Nano circuitry running at 16MHz, without the USB to Serial converter, as well as a 3v to 5v level converter on the I2C port ( A4 and A5 ), as well as another ...

ESP8266 / ESP32 / WEMOS / Universal terminal block (DIN rail & stand-off)
Staehli Jul 26,2022
Working with different Dev Kits from Espressif? Do you want to mount these to a DIN rail?Do you just want to use terminal blocks with screws instead of soldering?Here you go! This little board accepts most of the ESP boards out there:ESP8266 Dev Kits (30 and 38 pins, wide and narrow boards)ESP8266 WeMos D1 Kits and the likeES32 Dev Kits (30 and 38 pins, wide and narrow boards)However it does not fit for Arduino Nano or similar smaller boards.There are 3mm holes with a distance of 300mm for mount...

AtMega3208-XFR development board
Homer Jul 26,2022
I created this little development board for the atmega3208-xfr. It is a SSOP28 package and thus other SSOP28 packaged IC's can fit on as well, they just won't have the convenient text for pin names.

Monitemp (Monitor Temperature And Humidity)
Andrei Florian Jul 26,2022
AbstractFigure 1: A Monitemp device Not everyone has a thermostat in their home, and even if they do, most of the time you can only check the temperature by looking at a physical screen. One can’t check their home’s temperature or humidity levels online, from any device. My solution to this problem is Monitemp. Monitemp is a small device which continuously monitors the temperature and humidity of its environment and utilises Temboo’s Google Sheets choreo to upload this data to a spread...

Making Famous Magic Wand 33x Faster
AlexMiller112 Jul 25,2022
IntroThis case is a remake of a well-known “magic wand” experiment. Last year, Pete Warden, the famous creator of the TensorFlow Lite for Microcontrollers (TFLM) framework, ran a workshop on building a digital ML-based magic wand at the tinyML Summit. Today, it’s one of the most popular gesture recognition experiments as only on Hackster.io, dozens of “magic wand” tutorials can be found.Can I build a model better than Pete Warden? It turned out that today everyone can do it. Only a year ago, the...

DRV Driver Rc Car Pcb
electronicguru0007 Jul 25,2022
About the driverAt the heart of the DRV8825 driver, you will find a chip made by Texas Instruments: the DRV8825 Stepper Motor Controller IC. This integrated motor driver makes interfacing with a microcontroller super easy as you only need two pins to control both the speed and the direction of the stepper motor.The driver has a maximum output capacity of 45 V and ± 2 A which is great for driving small to medium-sized stepper motors like a NEMA 17 bipolar stepper motor.If you ...

Ac Dimmer Pcb
electronicguru0007 Jul 25,2022
In our household, most of the appliances are powered from the AC supply such as Lights, TVs, and Fans, etc. We can turn ON/OFF them digitally if needed, using Arduino and Relays by building a Home automation setup. But what if we need to control the power of those devices for example to dim the AC Lamp or to Control the speed of the Fan. In that case, we have to use phase control technique and static switches like TRIAC to control the phase of AC supply voltage.So in this tutorial, we ...
