ArEboy powered by ESP8266 (Arduino Nano)
Saballa Sep 18,2018
### DESCRIPTIONArEboy running on ESP8266(WEMOS) while using Arduino Nano as an IO Port for button....Sound and LED are driven by Arduino Nano... ESP8266 and Arduino Nano connected thru I2C with Voltage Level Shift for button(sound to be implemented)...Provision for SD card (SD bootloading.....)Logic and Graphics processing used the ESP8266 while the Arduino Nano used for IO and Sound/Tone  generation....Still  at early stages....Run Arduboy Games...Will use customize Arduboy ...

Dust Collector Full Detector
Mackey Sep 18,2018
Determines when a dust collector drum is full by detecting when a small DC motor driving a paddle inside the drum stops due to shavings preventing the paddle from turning. This version has the option of using a transceiver to send a message to a companion project: https://www.pcbway.com/project/shareproject/Audio_Alert_v2_3.htmlFull assembly instructions and parts list can be found here: https://www.instructables.com/id/Dust-Collector-Full-Detector/3D parts STLs can be found here:...

Audio Alert v2.3
Mackey Sep 17,2018
This Audio Alert board is placed between an audio source and an audio consumer such as an FM transmitter or amplifier. When the alert box wirelessly receives an encoded message, it breaks into the audio stream from the source and plays the mp3 sound clip related to the message received. The board has 3 MP3 file sources: NOR Flash, USB memory stick, and SD card.Software, schematic, parts list, and 3D STL files for a printed case can be found here: https://www.thingiverse.com/thing:3102114The...

ESP8266-01 Programmer easy connection
Lautaro Tourn Sep 15,2018
With this PCB you can easily flash your ESP8266-01 withoout adding wires or complicated connections to breadboard.You just plug your USB-TTL converter (CP2102 or PL2303), select the mode (flash or normal), click reset and go.The only components you need are the push-button por reset and the interruptor for mode select (this puts GPIO0 to GND or 3,3V.

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. ##...
