SDR Transceiver 10-160 meter band
YE3CIF.COM Sep 14,2018
This SDR was designed from some of my experiments so far, from various sources with improvements here and there so that I can get maximum results.LO using Si5351A which is controlled by Arduino Nano produces a frequency that is wide enough Max 160Mhz, of course allows us to make Exciter up to 10M band. LO = work freq x 4.My BPF takes from the us5ncj design using an already-built Inductor, so it is practical without the need to roll.Parts of TX, RX, and RF Preamp are not much different from the S...

Arduino acceleration logger
Kristoffer Sl?ttsveen Sep 11,2018
### DESCRIPTIONCurrently, this design has some faults! the 3k6Ohm resistor should be a 2k4Ohm in stead. The 5V regulator pinout is wrong compared to the footprint shown on the board. The Arduino MKRZERO footprint is 2.54mm too wide. ### TECHNICAL DETAILS / COMPONENTS### LEARN / TOPIC / BUILD INSTRUCTIONS

Inteligent electronic load using ST-Nucleo-L432KC
Tadeáš Pilař Sep 07,2018
My goal is to create simple electronic load. Requirements are 2 chanels, power monitoring, constant voltage mode, constant current mode, constant power mode. The device should also be able to discharge batteries, monitor power drained and stop discharging when threshold voltage is reached. Each channel should be able to handle 5 amps with possibility for future upgrade.As the brain of this device was choosen ST-Nucleo-L432KC development board. Its 2 DACs will be used to drive power transist...

Pro-A-WiFi01-Shield
Jesus Villarroel Aug 30,2018
### DESCRIPTIONThis is an Arduino UNO shield which was designed to ease the flashing process of the ESP01 module. When I started programming this module, the process was sort of messy and complicated. Required a lot of wire jumpers along the breadboard, the ESP01, and the Arduino UNO. Using this shield, it will require just placing some jumpers to flash the WiFi module.Moreover, this shield can be used to connect the Arduino UNO to the cloud through the ESP01 using AT commands. ##...

nRF24l01+ Joystick Remote Control
Taylor Amarotico Aug 24,2018
### DESCRIPTIONI designed this because I wanted a compact remote control so I could easily control my tracked vehicle I designed. It utilizes a nRF24l01+, an Atmega328p, and a joystick to make a simple circuit that does not require a ton of components. It also has a bootloader header, and a programming header so you can quickly and easily flash a bootloader to the Atmega328p, and then easily program with only a few connectors. It has a 5v power regulator for the Atmega328p as well as a 3.3v powe...
