Samidha Verma — Sun, 14 Jun 2020 09:26:56 +0000

It would be a fun ride to metamorphose any switch, joystick, sensor or other electrical gadgets into a USB keyboard and/or mouse. To begin with, you can convert any input device into a controller for your computer programs or games. And the most fascinating portion of this tutorial is yet to be explored as you can do every conversion with one line of code, inside the relaxing margins of Arduino. This interesting tutorial by Jimb0 of Sparkfun is dependent to this micro friend: the SparkFun Pro Micro! The Pro Micro is a small, Arduino-compatible microcontroller positioned around an ATmega32U4 - an 8-bit AVR akin to the ATmega328 with one colossal limitation: The 32U4 comes fitted out with a full-speed USB transceiver.

DIY Heated Bed for a Cetus 3D Printer

Engineers Garage — Fri, 05 Jul 2019 03:06:22 +0000

Heated bed is an added module to 3D printer, that ensures a controlled printing process. It assists in improving the print quality drastically by maintaining ideal conditions for the printer to function. This DIY heated bed is designed to monitor and set up the print bed temperature. Temperature plays an important role in the printing process; too hot or too cold temperature can lead to a mess. Additionally, the heated bed would provide extra power supply to the printer so that overload can be avoided and would give over-temperature protection beyond the usual monitoring.

How to turn an old Hard Drive into DIY Speakers?

Neha Rastogi — Fri, 05 Jul 2019 03:06:21 +0000

It’s always fun to work on an electronic project especially when it lets you recycle old objects that are otherwise thrown into the trash. Afrotechmods is a website run by an electrical engineer nicknamed as Afroman who publishes a bunch of interesting experiments with electronics through videos. His areas of interest include power electronics, robotics, and mixed signal design. In one of his videos, Afroman has described an interesting use of hard drive in the form of a DIY speaker. The project has been demonstrated clearly with the help of a video and doesn’t require any software installation. In order to build the speaker, all you need is a hard drive and some easily accessible tools like hex wrench, a multimeter, couple of thin wires, soldering iron, and an amplified audio source.

Arduino LCD: How to Connect a Liquid crystal display up to the Arduino

Samidha Verma — Fri, 05 Jul 2019 03:05:44 +0000

You are aware of various pros of an LCD (liquid crystal display) and its ability to perform and therefore in this Arduino LCD tutorial of arduinomylifeup, we will learn how to connect a simple 16×2 LCD up to the Arduino with this good little device.If you had some experience with the LCD boards, you must be aware of the fact that they are not assembled with header pins and hence, will need to be soldered on. With the availability of header pins, you can perhaps skip soldering but getting a worthy connection to the board will be challenging. The potentiometer in the circuit is used to control the brightness of the screen.

Modifying Casio PT-82

Samidha Verma — Fri, 05 Jul 2019 03:05:42 +0000

A Casio PT-82 was considered as a classic of Casio 8 bit technology before the famous SK-1 came in market. A LushOne kit can be used to modify simple keyboards. But PT-82 does not has a circuit bend as the SK-1.The useful modifications that can be made are quite limited. The sliding switches can be stripped back to individual components, plastics can be removed from the debris and the springs can be adjusted on the sliding switches.In one of the tutorials of Lushproject, base can be used to add a filter with LFO input to the cut-off frequency and a ring modulator with second oscillator input to the PT-82.
