PALPi Lite Edition
Arnov sharma Mar 14,2022
Hey everyone, how are you doing!So this is the PALPi V4 which is a DIY Retro Game Console powered by a Raspberry Pi Zero W.The IDEA here was to make a portable handheld gaming console that can run RETRO Games like Contra, Pokemon, Super Mario ETC.For Display, I've used a 4 inch Car Monitor Display which is controlled by Composit PAL output.As for the emulation OS, I used RECALBOX as it comes with many preinstalled games.In this article, I'm gonna show you guys the whole built process f...

IO-Shield for LoRa-Base
MakerIoT2020 Mar 13,2022
INPUT And Monitor Shield for LoRa Base ModuleIntroductionThis is a straightforward project compared to my usual PCB projects. It is one of a series of designs towards completing my LoRa monitoring system, that I plan to use on the farm to monitor various areas, such as intrusion detection, battery levels etc.The shield was designed to fit on top of the first LoRa Base Module. It was designed to allow easy, neat connections to Infrared Beam sensors, XYC-WB-DC Motion Detector, as well as to monito...

Sx127x-Ra-02-Test-Module with ATMEGA328P-AU
MakerIoT2020 Mar 10,2022
SX127x LoRa/FSK/OOK Prototype Radio BoardI recently had a requirement to do some automation/telemetry on the farm. Things went missing, unauthorised persons were trespassing on the property, helping themselves to eggs, chickens, ducks and produce. Something had to be done, and as there is nobody sleeping there at night, it had to be possible to get remote status updates in real-time.The farm is also completely off-grid, with solar-powered inverters taking care of all the water and electricity ne...

3 line to 32 line output expander
Yap Mar 04,2022
This project is described at Hackaday.The minimum lines required to use this board are: GND, SER (data), SRCLK (shift), RCLK (strobe). Vcc depends on the power arrangement. You should jumper the ~OESEL (output enable select) to ground if you don't wish to disable the display by signal, or vary the output with PWM, from a controller. The ~SRCLR input is only needed for resetting the output by the controller.This board is designed with optional aspects you can choose to include or not:As mentioned...

WeMos D1 (esp8266) Ebyte LoRa shield (10Km) with HardwareSerial and voltage regulator
Mischianti Feb 24,2022
The new shield is similar but has more features here than the breadboard schema, even if it is limited to 3.3v of supply to the LoRa device.EByte LoRa E32 Wemos D1 shield to hardwareserialAs you can see now, there is a voltage regulator to power the e32 device, and RX, TX is connected to TX and RX of microcontroller, a pin is free to connect Serial to USB to debug on Serial1.So the PCB schema become soEByte LoRa E32 Wemos D1 shield PCB to hardware serialMore complex and with more pins and button...

WeMos D1 (esp8266) relay shield
Mischianti Feb 18,2022
WeMos D1 3v module relay shield at work main.One of my project’s most used components is undoubtedly the relay; its working is quite simple; you can find It as a module or only the relay.You can find multi-voltage relay modules on AliExpressThe only problem you can have is that relay needs some power to be activated, so It’s preferable to use a transistor like 2n3904.You can find 2n3904 transitor on AliExpressHere is a simple breadboard connection schema; as you can see, I use a microc...

3 speed Fan controller with Local control
MakerIoT2020 Feb 17,2022
Bymakeriot2020 FEB 17, 2022  ESP8266, IoTA typical desktop oscillating fanDesk or floor-standing fans are one of those appliances that will be present in almost every home or office. Some of the newer ones may already have remote control of some sort, while the older models won’t. It is however quite easy to do a retro-fitted controller to most of them, and at the same time, give them some (limited) intelligence.Your typical oscillating fan does not have a lot of intelligence...

Relay Shield PCB Design Useful for IoT Applications
Arshmah Shahkar Feb 08,2022
Every household has electronic devices which are a major part of our everyday life like dishwashers, washing machines, boilers (water heaters), kettles. All of the previous devices are a combination of mechanical – electronic – power sets. The main part of devices operation is electrical power. It’s well known that AC electrical power is dangerous for humans and that’s exactly the type of power for devices operation. For example, if you leave your kids at home alone, they could turn on, by accid...
