Fresh hacks every day
We see LEDs used in all kinds of projects but rarely does someone build a home lighting system from scratch with them. [Paulo Oliveira] decided to give the idea a try, included a fading power supply for the LEDs which he built himself. Here you can see the installation at full brightness, but his controller also offers a single lower … Read the rest
This simple device, paired with some creating code will let you become your own home security monitoring service. It’s called the PhantomLink and [Adam] started the project as a commercial venture. He recently decided to go open source with the hardware and will soon be posting a guide on how to program your own web interface too.
We just … Read the rest
[Viktor's] washing machine did a good job of cleaning his clothes, but it kept a bit too quiet about it. The machine doesn’t have an audible alert to let him know the cycle has finished. He decided to build his own alarm which can just be slapped on the side of the machine.
You can see that a couple of … Read the rest
This project from a few years back is an interesting take on a metal detector. Instead of building a detection circuit, [Bruno Gavand] replaced the external clock crystal with an inductor. Here you can see the inductor coil next to the PIC 12F683. You can see two components jumping from one breadboard to the other. These are smoothing capacitors … Read the rest
That finished look for your project is all about the enclosure you find to host it. We think [Punge] really did a great job with the case for this DIY intervalometer. The build section of the project page links to the company that makes the enclosures. They’re meant to host round PCBs with several options for button configuration. Combine … Read the rest
[William] developed this temperature candle as a tool to help keep babies safe as they sleep. It seems that ambient temperature has an effect on Sudden Infant Death Syndrome (SIDS). This device is meant to alert you when room temperature is outside of the recommended envelope.
The board hosts an eight-pin PIC microcontroller (12F683P), a temperature sensor, RGB LED, and … Read the rest
An inductor and 8-pin microcontroller are all that make up this barebones RFID tag. You might have done a double-take when first seeing the image above. After all, there’s nothing hooked up to the power and ground pins on the chip. As [Ramiro Pareja] explains in his post, the power is actually supplied via the I/O pins to which … Read the rest
