“This spooky electronic ghost is a 555 LED flasher circuit encapsulated in silicone rubber.”
“These days good quality oscilloscope is not an expensive instrument and, we can see it in most workbenches. With the advancement of oscilloscopes, simple testing tools such as logic probes are not as popular these days. However, if the oscilloscope …
“This sensor board provides frequency output as per relative humidity value. The project is based on a unique capacitive cell, this relative humidity sensor is designed for high volume, cost-sensitive applications such as office automation, automotive cabin air control, home …
“So what is this thing? Basically it’s a handheld device that allows you to “hear” RF sources. Regular rf receivers single out a particular frequency and decode it into some type of information. This device on the other hand …
“Automatic water level controller for the submersible pump and overhead tank with 555 timer IC. Also check the underground tank water level. In this mini electronics project, I have shown how to make an automatic water level controller for the …
“In this project we will keep it simple when it comes to wireless audio communication. Instead of trying to use an nRF24 or RF modules, we will go back to the old days in which they used AM radios. I …
“In todays article, I will show you running lights based on three popular microcircuits: an operational amplifier microcircuit LM358, a timer microcircuit NE555, and decimal counter microcircuit CD4017. The running lights schematic diagram and printed circuit board (PCB) were developed …
“I’ve hit a pretty significant milestone with this Instructable - my 200th! It’s been a busy 9 years, building and learning a lot of new skills whist producing these 200 ‘ibles - and it’s been a blast. Thanks to …
“This project is about building an adjustable high voltage generator (DC) from a low DC voltage supply. The voltage supply can range from 5V to over 25V (I use a 9V supply). Higher voltages can require heat dissipators attached to …
“It’s a programable “laptop”. Hardware that allows me to program different activities in a nice box This is a long project, I will divide it into small bits so people can take pieces and set up their own. I …
