Fresh hacks every day
We love all of the projects that are coming out for the 555 design contest, so we thought we would share a couple more that have caught our collective eye. Have a 555 project of your own? Be sure to share it with us, and keep an eye out for the contest submission dates. Read on for a few of our project picks. … [Read more...]
Wielding the power to melt glass or instantly ignite most day to day materials can be intoxicating pretty fun. With a little math, a lot of patience, and 5,800 1cm pieces of mirror, this build requires welding glasses just to look at the 1-2cm focal point. With an idea rumored to date back to Archimedes, this more portable parabolic project is perfect for your home burning needs. Unfortunately, … [Read more...]
Here at Hackaday, we see microcontroller based projects in all states of completion. Sometimes it makes the most sense to design systems from the ground up, and other times when simplicity or a quick project completion is desired, pre-built system boards are a better choice. We have compiled a list of boards that we commonly see in your submitted projects, split up by price range and with a little … [Read more...]
Cats do what they want, which rarely coincides with what their owner wants them to do. In [Dumitru]'s case, his girlfriend's cat [Pufu] tended to make it outside into the cold more often than desired. Rather than settle with the normal bell which gets obnoxious even when the cat isn't misbehaving, he decided to put together a custom Cat Finding collar. He used a PIC microcontroller as the brains, … [Read more...]
Sometimes it helps to have an entire set of tools with you to tackle a problem, and sometimes it helps to take the discreet route. [StenoPlasma] took the latter of these approaches, and stuffed a USB hub, a 16 GB flash drive, and an Atheros based USB wireless adapter into a regular looking USB mouse to make a Linux bootable system in a mouse. Because he chose the Atheros adapter, he is also … [Read more...]
When it comes to using servos in projects, there is a definite distinction between the cheap ones and the expensive high power and precision models. The OpenServo project gives you a couple options for enhancing your servo experience. By replacing the control board with a new one based on a familiar microcontroller, a whole new set of features can be attained. For those of you out there with a … [Read more...]
Broadcast TV has come a long way from adjusting the rabbit ears on top of the set just to get a fuzzy black and white picture. While nowadays there are often HD signals broadcast in most areas, it can often still be critical to redirect an antenna to get the best possible signal. By harvesting a stepper motor from an old 5 1/2" floppy drive, and using a PC's parallel port to control it, this … [Read more...]
