Hide the AC Units In Your Home With 2 Creative Interior Designing Ideas

Most homeowners look for unique and creative ways to improve the home décor of their house or apartment. Unfortunately, they often fail to hide their ugly AC units in the room, and they become an eyesore when compared to the rest of the room. Experts from home décor and interior design companies state that most of the time, homeowners do not even place the importance of the AC unit in their interior designing plan. Therefore, when all the work is completed, they just place the AC unit in any corner they deem fit, and this spoils the whole look.

8 Knitting Blogs For Your Inspiration

Everybody needs inspiration for a lot of things. From fitness, food, fashion to art, work, books, and even knitting. The digital age has made it easier for you and me to find some sense of artistry and creativity. If you are a beginner in knitting, the web is a good place to start. There are many available resources and everything is circulating within the network–books, workshops, videos, and blogs! What are blogs? Blogs are websites that mostly contain published content. Photos, videos, links, and other elements can be added there too. If you are looking for a knitting inspiration, something that will provide you tutorials on knitting or encourage you to work on your projects in the best way possible, you can visit these portals through any of your devices for free!What are the Top X knitting blogs that you should in 2019? Read on!

Fixing Renault Scenic II fan controller block

Renault Scenic II fan fails quite often. In some cases you may notice that not all speeds selected from dashboard works, or works occasionally. But most often fan stops working at all. Of course first step to check is fuses. If fuses seem to be OK then the only way to look is at fan speed controller (sometimes called fan resistor). The easiest and most expensive way is to call service leave them to do repairs. But if you have some engineering blood, you can do it yourself by spending less than hour of your time and probably only couple bucks.

Video tutorial on using voltage multiplier

Dave has made an excellent video tutorial on building and using Dickson voltage doubler made if diodes and capacitors. This appears to be a cheap and easy way of rising voltage for low power applications. For instance, if you microcontroller circuit is powered from the 3V power supply and you want to attach 5V LCD, it may be useful to consider a voltage double to increase supply voltage instead of designing additional power supply branch. In the tutorial, there are real measurements made with different loads attached. [source]

Nicer PC HDD activity indicator

Usually, computer hard drive activity is indicated with a single flashing LED when there is write or read operation performed. [Harvey Wilson] wanted something different than just a flashing LED and came out with an indicator. He replaced a single LED with 10 LEDs mounted in a circular shape. After digging some info from the Internet, he found the HDD signal nature and built the 4017 counter based circuit which accepts each incoming LED signal and then increments a counter. All 10 LEDs are connected to counter output pins, so each event lights makes the feeling of running lights.

Do you know all features of your scope?

Probably you found yourself in the situation when you couldn’t get a clear view of a more complex signal on your scope. For instance, it is pretty hard to synchronize packet data waveform. All you get is a mess on your scope screen. With an analog scope it is almost impossible to get it while on Digital Storage Oscilloscope (DSO) you can store trace in memory and then analyze it. But this isn’t very handy. So there is a nice feature on most scopes which is called Trigger Holdoff. Check out this video tutorial from eevblog where Dave shares his thoughts about how this feature can be used in real life situations.

Line sensing robot with no micros

We used to see more and more projects where microcontroller is a must part. This leaves of board those who like things to simple and understandable. This line following robot relies only on analog electronics which allows robot to sense dark line and follow it. Schematic relies on bunch transistors that act as switches when black color of line is sensed with phototransistors.
