Arduino MKR WiFi 1010 SPI Flash memory shield
Mischianti Mar 01,2022
Arduino SAMD (NANO 33 and MKR): SPI flash memory FAT FSI have a couple of Arduino MKR WiFi 1010, and It’s potent, but I notice a tedious lack: there isn’t a Flash memory to store data. I have already written some articles on controlling external SPI Flash memory “How to use external SPI Flash memories”, but now I’d like to simplify the process, and I create a simple PCB shield to add external SPI Flash memory in the fastest way.The PCB is straightforward, and I added some jumper soldered to sele...

Wireless Energy Transmission System only using PCBs
Arnov sharma Mar 01,2022
Hey guys how have you been!So here's yet another crazy experiment based on the work of Mr. Nikola tesla.My Edition of "WIRELESS ENERGY TRANSFERRING SETUP" was made entirely from PCBs.The only difference between Mr. Tesla's version and mine was that my setup didn't work as it should.All the joke aside, my setup does work but the problem is the efficiency.Why it's not working efficiently?Well because the design of the coil is a joke. I added many traces and didn't leave too much space at the cente...

Simon Says Arduino Uno Shield
Lelepg Feb 26,2022
This project is a PCB I've been wanting to make for a long time. When I was starting to learn arduino, I decided to make a simon says game, like the one in the picture bellow.I managed to do it, and I think it turned out great for a beginner's project BUT there were so may wires and the buttons ended up being hard to press because of the wires.So I decided to make a PCB for the project, and since I was using aduino nano, why not turn this project into an arduino shield? So it's learning arduino ...

MCP23017 16 bit GPIO Expander Demo Board
Reboot Feb 25,2022
The MCP23017 provides 16 GPIO over I2CEach pin can sink and source current when used as outputs, making it useful for driving hardware like a micro controller GPIO.This pcb has 8 relays (G5V-2 low signal DPDT https://omronfs.omron.com/en_US/ecb/products/pdf/en-g5v_2.pdf) to test the GPIO output control, 4 buttons to test input control, and 4 GPIO connected to header pins to be used as inputs or outputs from outside the pcb.The 2 interrupt pins are available on test points, and the relays have th...

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...

Eren Yeager PCB ART
Arnov sharma Feb 24,2022
Hey guys and how you doing!So this is the EREN YEAGER PCB ART or a Blinky Board which is based around 555 Timer IC.On the TOP side, I've added a custom silkscreen layer that consists of a BMP image of EREN YEAGER Titan form.For those of you who have no idea who or what EREN YEAGER is, well let's just say he's one very disturbed lad from a fictional show called "AOT or Attack on titan"I made this setup as a soldering challenge kit, We solder all the SMD components with a soldering iron and the en...
