Over 45 Builds for the Legendary 555 Chip (and the 556, 558)

The 555 timer IC, originally introduced by the Signetics Corporation around 1971, is sure to rank high among the most popular analog integrated circuits ever produced. Originally called the IC Time Machine, this chip has been used in many timer-related projects by countless people over decades.

This book is all about designing projects based on the 555 timer IC. Over 45 fully tested and documented projects are presented. All projects have been fully tested by the author by constructing them individually on a breadboard. You are not expected to have any programming experiences for constructing or using the projects given in the book. However, it’s definitely useful to have some knowledge of basic electronics and the use of a breadboard for constructing and testing electronic circuits.

Some of the projects in the book are:

  • Alternately Flashing Two LEDs
  • Changing LED Flashing Rate
  • Touch Sensor On/Off Switch
  • Switch On/Off Delay
  • Light-Dependent Sound
  • Dark/Light Switch
  • Tone Burst Generator
  • Long Duration Timer
  • Chasing LEDs
  • LED Roulette Game
  • Traffic Lights
  • Continuity Tester
  • Electronic Lock
  • Switch Contact Debouncing
  • Toy Electronic Organ
  • Multiple Sensor Alarm System
  • Metronome
  • Voltage Multipliers
  • Electronic Dice
  • 7-Segment Display Counter
  • Motor Control
  • 7-Segment Display Dice
  • Electronic Siren
  • Various Other Projects

The projects given in the book can be modified or expanded by you for your very own applications. Electronic engineering students, people engaged in designing small electronic circuits, and electronic hobbyists should find the projects in the book instructive, fun, interesting, and useful.

Best pour-over coffee maker
This pour-over is my favorite. I've tried metal mesh and ceramic pour-over. This set up is the best, it aerates the coffee as you pour.

Love it
I’m making great coffee and tea. The magnet is great to. The drip makes the flavors better.

I Was WRONG!!!
I ordered this because I wanted to try it out. First, make sure that you have the correct filters available or you will get irritated too... It uses a V02 filter (the small triangular kind). Then after reading the instructions I realized how many steps are required to make a cup or two of coffee with this contraption... : ) I would really recommend making yourself familiar with this type coffee brewing PRIOR to making this your first cup of coffee in the morning! lol I also didn't have a Gooseneck-style teapot (I did get by without it, but I can see where you will want that style of teapot to make the pouring process more precise!), but I improvised and used a regular teapot and it did work. Keeping in mind, I had NO idea what a pour-over coffee pot involved to make a cup of coffee, hadn't had any caffiene yet and have been battling a virus for over a week now, up until I tried the coffee I was ready to complain about this coffee pot... Then I tried the coffee...OH MY!!! This was one of the BEST cups of coffee I have ever had! I used old, bleached white coffee filters, some flavored, pre-ground Cameron's coffee (so not even a strong grind), and I couldn't shut up! This is one FABULOUS coffee maker! I am SOLD on a pour-over style brewed coffee! If you have never tried one of these, please do! It makes a fabulous cup of coffee!

Just as described
Like I needed one more thing on my countertop! But it's coffee, so I'll make it work out. This is first product of it's type that I've used. I've seen it offered in coffee shops and thought that slower drip process must create a nice coffee. So, I've tried and I love it. Just follow the instructions, and get the filters at the same time or pick some up at your grocery store. If you're like me, you'll want to try it out right away. I enjoy a dark roast and this really improved the flavor of my usual brand of coffee. The only thing that concerns me is the beaker is made of pretty thin glass. I'm wondering if thicker glass would also help to keep the brew hot as I make enough for two cups. Overall, I'm really happy to have found this.

Durable glass coffee container, nice to use
Previously, we were using an old metal coffee can to store our coffee. The problem is that because it was not transparent, we found ourselves frequently running out of coffee. Out of sight, out of mind. This glass container lets us see how much coffee we have left, but the fact that the glass bottom didn't appear to be reinforced had concerned me somewhat, particularly because our kitchen counter is hard ceramic tile. Well, it seems that these glass containers are made of borosilicate glass, which is a special glass made with boron that has superior strength and durability. Apparently, borosilicate glass is made at a higher temperature, and slowly cooled to room temperature in a process called annealing. Annealing involves controlled cooling to relieve internal stresses and improve the strength and durability of the glassware. Still, I wish that the base of the glass container was thicker, like most bottles and jars. The lid fits on snug and airtight, and there is a button on top that you can push to pump out air and create a vacuum seal. I cannot comment on the worth of this nifty aspect, as the taste of our coffee has not noticeably changed after we began storing our beans in this container. Still, it is a nice container, it looks nice, appears to function well, and hasn't cracked yet. It even comes with a small sturdy steel coffee scoop. And we get to see our coffee all day long.
