Fresh hacks every day
[Ben] wanted a switch mode power supply for his breadboard. He ordered a PTH08080 module which is made by Texas Instruments. The spec sheet would make it a great choice for him, but he was not happy to learn that the pinout doesn’t conform to the 0.1″ spacing used by solderless breadboards. His solution was to make a breakout … Read the rest
This hat has a chasing LED feature thanks to our old friend the 555 timer. [BananaSlug] even built in the option to change the speed at the push of a button.
His design starts out with a costume hat. Each of the 25 LEDs is soldered to a 2×4 hole chunk of protoboard. The LED package is pushed through a … Read the rest
This is a blinky ball that [David] designed, built, and programmed himself. Does it look familiar? It should, he took his inspiration from the original prototype, and the Hackerspace-produced derivative. [David's] version is not as small, or as blinky, but in our minds the development process is the real reason for building something like this. He took … Read the rest
[Scot Kornak] got his hands on the new STM32 Discovery Board. He got his as a free giveaway, but at only $18 he probably would have picked one up anyway. His one complaint about the device is that he dual pin-headers which break out the ARM processor’s pins are not the most convenient for hooking up external components. He decided … Read the rest
Here’s [Rob]‘s free form circuit that’s a Christmas ornament for geeks. It looks great, but sadly isn’t powered through a Christmas light strand. It’s just as cool as the skeletal Arduino we saw.
Well this is interesting: protoboard that’s specifically made to make SMD soldering easier. The guys at elecfreaks went through … Read the rest
[Rich Decibels] decibels received so much interest in his original sequencer build that he decided to make another one that was a bit easier and less expensive to replicate. The original design, called the Kequencer, featured a nicely finished look for the user interface. For the Keyquencer 2.0 he decided that adding a lid to the enclosure meant … Read the rest
Reader [Osgeld] is a board-layout ninja. He populated this 4×4 LED matrix board without having a layout plan to start with. Watch it develop in slideshow format to see the art work he performs. The display is driven by a shift-register and he’s included all the proper parts like resistors and transistors, yet he makes everything fit. Why is this … Read the rest
