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
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 Hallow...

ESP8266 Remote Relay
Reboot Oct 23,2022
This pcb has a WeMOS D1 Mini with ESP8266 to control the on board relay.Control of the relay can occur wirelessly, and the ESP8266 UART pins are also available on a header to optionally allow an external RS485 or bluetooth module to be used.The Github project uses ESP-NOW to communicate between this relay control board and another ESP8266 board that uses a current transformer: https://www.pcbway.com/project/shareproject/SCT013_Current_Monitor_for_ESP8266_cc7ccd2e.htmlWhen the current transformer...

Arduino hearing test device - Audiometer
Pavleski Oct 22,2022
  An audiometer is a machine used for evaluating hearing acuity. They usually consist of an embedded hardware unit connected to a pair of headphones and a test subject feedback button. This device typically transmits pure tones to the headphones of the test subject at varying frequencies and intensities, and records the subject's responses to produce an audiogram of threshold sensitivity.I recently took a hearing test in a professional facility, and I received the results in the form o...

PCB Candle that glows forever- KINDA
Arnov sharma Oct 22,2022
Hey everyone how you doing!So this is an EVER GLOWING CANDLE PCB that will glow forever and never run out of wax because it's not made out of wax.However, it will stop glowing after a month of constant blinking when the battery runs out.The Idea here was to make an awesome and safe night light-decorative light for my desk, Aroma candles, and other decorative candles look great but they are dangerous to keep around, the fire hazard is one of the problems that can cause because of Candle...
