In this project, we are building a useful board which should take place on your bench. It is an adjustable electrical load which can sink up to 5A @ 30W continuously. This board will come to aid when you need to draw an exact amount of current from a supply. For instance to learn the

I wanted an in-circuit ESR meter (equivalent series resistance meter) to aid in determining the condition of electrolytic capacitors without the need of desoldering them first. When capacitors fail you will often have some signs of failure such as bulging of the capacitor top. Starting in approximately 2002 and continuing till about 2010 there was

Talking about using Arduino to play music, is it the Arduino MP3 shield not the first thing you come up with? Or maybe some geeks will consider about tone() function? They are not the things our topic is about today. We don’t need any MP3 shield, tone(), or SD card. Only Arduino can perfectly play

Pi-files: Frontdoor light switch based on local sunset/sunrise I have a couple of front door LED lights which I would like to switch on automatically during the evening/night. The two conventional methods that are commonly available had their disadvantages: A timer switch is the easiest and cheapest solution, but doesn’t take into account day light

Pi-files: Doorbell alert with pushmessage and mail with webcam footage Actually the first ‘project’ I ever did with a Raspberry Pi was sending a push message to my Iphone. It was 2012, I was lying sick in bed and found a new app on my Iphone called Pushover (what else to do when you’re sick?).

Lets start with a warning: this project controls water. Electricity and water really don’t mix and there is a real risk of electrocution and or death if you are not careful. Build this project at your own risk and I won’t be held responsible for anyone who builds this. make sure you use a battery
