PALPi V5 Handheld Retro Game Console
Arnov sharma Oct 28,2022
Hey, Guys what's up?So this is PALPi which is a Raspberry Pi Zero W Based Handheld Retro Game Console that can run pretty much every retro game, from SNES to PS1.The brain of this project is the RECALBOX OS, an Opensource Game Console OS based on Retro Arch.Raspberry Pi Zero W is being used here with a custom PCB that has SMD Buttons on the front side and a battery on the back.This is currently the Fifth Iteration of the PALPi Game Console System.Its previous version was great but it had a batte…

High Power LED Board
Arnov sharma Oct 27,2022
Hey what's up you guys, this is a HIGH POWER LED BOARD that I made completely from scratch.It consists of Four XPLAWT LEDs that are High-Intensity LEDs each rated for 3A Max and their operating Voltage is 2.8V to 3.2V.Cree Makes these High Power LEDs and you can read its datasheet for more info- https://www.mouser.in/datasheet/2/723/ds_XPL-2327187.pdfAs for driving the HIGH Power LEDs, an LED Driver IC was used.Why LED Drivers are used?An LED could be easily powered through any DC source but wha…

WS2813 buffer
DIY Oct 26,2022
WS2813 bufferThis is a versatile buffer for WS2813 LED strip. It is a LED with strong SN74LVC2T45DCTR buffer for the serial output that allows to send serial I/O data up to few meters; it is designed for mid range serial LED strip communication.It has the same dimension of a WS2813 LED strip (16,5 x 10 mm), and it can be configured as LED pixel with strong buffer or as a simple buffer to send data.Buffer with LED configuration: JP1 solderedBuffer only configuration: JP2 and JP3 soldered

WS281x LED RS485 transceiver
DIY Oct 26,2022
WS281x 485This is a versatile and cofigurable RS485 TX-RX transceiver for long range serial LED strip communication.If you need to send your data to a remote LED strip, you can use one PCB as TX and one as RX, it's easy!They can also be powered from 5V to 12V so all different kind of LED strips are supported.The PCB can be configured as RX or TX by soldering the jumpers and using the right resistor:RX configuration: R2 and JP3TX configuration: R1 and JP2 soldered

Building a dynamically efective robotic leg.
MiguelAsd Oct 26,2022
Along 3 years I have been trying several leg mechanism, at first I decided to do a simple desing with tibial motor where placed on femur joint.This design had several problems, like it wasn't very robust and the most importat is that having the motor (with big mass) that far from the rotating axis, caused that in some movements it generate unwanted dynamics to the robot body, making controlability worse.New version have both motors of femur/tibial limb at coxa frame, this ends with a very simple…

5.1 channel analog audio processor
Dilshan Ranmal Jayakody Oct 24,2022
In this project, we developed a 5.1-channel analog audio processor using PT2322 IC. PT2322 is an inexpensive analog audio processor introduced by Princeton Technology Corporation. It contains 6-channel individual channel attenuators, a 3-way tone control system for front-end speakers, and a 3D audio simulation system.In this design, we combine PT2322 with Arduino Nano and interface it with PC/embedded computing boards through a USB port. Native GTK UI application provides to control all function…

ESP8266-12E in Arduino Form Factor
MakerIoT2020 Oct 24,2022
ESP8266-12E in Arduino Form FactorAs a followup to my recent ESP32-S in Arduino Form Factor device, I decided to also produce a similar circuit board for the ESP8266-12E. Although some people mostly consider these as obsolete, I still find them extremely useful for small projects, and thus use quite a lot of them. With their lower total pin count and similar low cost to the bigger ESP32 modules, these do force you to get quite creative with the available pins, as well as how and what you can int…

PCB DIYA because Diwali is coming
Arnov sharma Oct 23,2022
Hey Guys what's up!So here's something HOT, a PCB DIYA that is powered by an Attiny13 MCU, it has two different LED Driving Mosfets that turn ON and OFF LEDs in a sequence and that emulate a flame.A "DIYA" is an OIL LAMP that is usually made out of clay or metal, they are symbolically lit during prayers, rituals, and ceremonies.Diyas represents the triumph of light over dark, good over evil with the most notable example of this being on the day of Diwali.Diwali is Essentially a Hindu Halloween.M…
