Hi! I uploaded a movie of working 230V dimmer example. I am working on the second part of the project lately - voice recognition part based on Raspberry Pi. I had some troubles with recording, processing and recognizing only the part of the sounds that are over some level of noise. That saves a lot of computational power. I believe I got the solution. As soon as I have some example working I will give you a heads-up. ...
It took me some time to solder everything together, but finally I got it working. Bulbs and lamps supplied with 230V are not so easy to dim. You cannot just take PWM signal from uC and simply use it as for DC powered lights. However, there are various ways to accomplish dimming. You can check some other methods online, for instance, the method to relay power from the bulb to some resistor, but still you have to pay for this wasted energy. There is a better way to use only some percentage of ener ...
While I was waiting for my electronic parts to arrive, I took a look at Creator 3.0. I have to say that this IDE is something else than I have expected. With Cortex MCUs I usually deal with M3 and I use free compilers with Eclipse. Now imagine my surprise after I have opened a simple LED blink example. It is really nice to use this tool. Using components, just like in FPGA development, really speeds up the whole process. Granted, you have to spend some brief time to get familiar with this tool, ...
In this post I would like to share with you my opinion on some types of light sources you can buy at stores. There are divided opinions about the LED supremacy (or not) over CFLs (energy saving bulbs). I did some calculations and reading what could be better for average Joe and I have to say this so called supremacy is a little fuzzy for me right now. Regardless, let’s start from the beginning. Some time ago there were practically no options. You wanted a good source of light you bought 10 ...
Hello to you all! I would like to give you an overview of my project idea I am planning to execute for this challenge. I have called this project Smigth as a shortened version of smart light system. Probably all of us have seen some movies on youtube showing automation systems for homes. I don't know about you, but I would like to have one of these at my place. There is one tiny problem which prevents me from getting it. These systems are pretty expensive. That is why I want to realize an afford ...
