“I have built a binary counter without using decoder. The diodes do the magic while the materials are: 1-7490 counter, 4-1N914 diodes, 1-555 timer, 2-4.7Kohm, 1-100uF capacitor, and 4-5mm LED’s.”
“In electronics, a device is said to be a latching device if it maintains any particular fixed state even after removal of the input signal. The same also applies for electronic/electromechanical relays. Basically the electromechanical relays that are used …
“In this blog post, I will show you a simple hardware hack to make your mouse capable of rapid firing (or automatic continuous clicking). Of course you can always resort to software mods to achieve the same goal, but admittedly …
“Have your dice ever fallen off the table after you rolled them when playing a board game? Yes? Say no more because in this instructable I will show you how I made electronic dice with the famous integrated circuits NE555 …
“Hello everyone, this is my first intractable and I am going to share my project of low cost 4 channel WiFi switch. My requirements: It should incur low cost as far as hardware is concerned. The device should be reliable …
“This instructable describes how you can build your own soil moisture sensor. There are a lot of instructables online about soil moisture sensors, but not that much about a self-made capacitor for measuring soil moisture content. With the simple resistance …
“So this year I thought to create a 3D model of it, with a bit of sound, adding an ISD1820. It goes just for 10sec, which is more than enough to bother my guests :-)”
“In this Instructable, I’ll be showing you how to make a cool RGB LED strip dimmer using a few potentiometers and a couple of 555 timers. I’m currently working on a larger project which involves using this circuit …
“Almost every project that I made in my life use arduino or just atmegas, but on last electronic lesson in my school I found small integrated circuit called 555. I have heard about it before but I was thinking that …
“Hello everybody! In this instructable I’m going to show you how to make a little piano using the common Timer 555 but with SMD components! SMD means Surface-Mount Device and those components are mounted or placed directly onto the …
