Fresh hacks every day
We would wager that most of the home etched PCB projects we see around here use the toner transfer method. But the next most popular technique is to use photosensitive ink which resists the etching acid once it has been exposed to light. Most people buy what are called pre-sensitized boards, but you can also get ink to make your … Read the rest
Here’s one of the best takes on a glowing display that we’ve ever seen. Currently [H] is using his creation as a fuzzy clock, but it is certainly capable of displaying just about any messages.
The project uses a wheel of luminous paper as the display surface. This has a glow-in-the-dark quality to it which can be charged up using … Read the rest
Making your own boards at home is among the heights of achievement for home tinkerers, and one fraught with frustration. The toner transfer process requires carefully peeling away layers of photo paper, and milling your own circuit boards is an exercise in complexity. One of the best options is using photosensitive copper boards, but this requires exposing the masked-off copper … Read the rest
NYC Resistor shows you how to have some fun with electronics from the junk bin. Their post called The Joy of Dumping encourages you to look around for older memory chips and see what they’ve been hiding away for all these years.
The targets of their hunt are EPROM chips. Note the single ‘E’. These are Erasable Programmable Read-Only Memory … Read the rest
Whether you’re trying to light your path, build your own night vision, or do some tanning at home, this flashlight has you covered. [David Prutchi] designed the high power flashlight with three swappable heads.
He built the base unit out of aluminum pipe. It’s got plenty of room for the four 9V batteries that act as the power source. … Read the rest
[mike6789k] wanted to spice up his dorm room, so he built a cool music synchronized light show that struck us as being very well thought out. We have seen similar music-based visualizations before, but they tend to be pretty basic, relying on volume more than actual audio frequencies to trigger the lighting.
[mike6789k] didn’t want to build “just another” synchronized … Read the rest
[David] has always wanted use UV LEDs to write on a phosphorescent surface ever since saw an article about it on Make. He accidentally purchased UV LEDs when he meant to buy purple ones, so he figured that his mistake was all the reason he needed to give UV light writing a try.
He built a PIC16F628 UV POV board … Read the rest
