Quick and Dirty MIDI Interface with USBASP

[Robson Couto] recently found himself in need of MIDI interface for a project he was working on, but didn’t want to buy one just to use it once; we’ve all been there. Being the creative fellow that he is, he decided to come up with something that not only used the parts he had on-hand but could be completed in one afternoon. Truly a hacker after our own hearts.

Searching around online, he found documentation for using an ATtiny microcontroller as a MIDI interface using V-USB. He figured it shouldn’t be too difficult to adapt that project to run on …read more

Drawing On an OLED with an ATtiny85, No RAM Buffers Allowed

Small I2C OLED displays are common nowadays, and thanks to the work of helpful developers, there are also a variety of graphics libraries for using them. Most of them work by using a RAM buffer, which means that anything one wants to draw gets written to a buffer representing the screen, and the contents of that buffer are copied out to the display whenever it is updated. The drawback is that for some microcontrollers, there simply isn’t enough RAM for this approach to work. For example, a 128×64 monochrome OLED requires a 1024 byte buffer, but that’s bad news if …read more

Custom ATTiny85 Board Powers Kids’ Light Show

We’ve often said that kids with hackers and makers for parents must be some of the luckiest kids in the world. While all the other children have to settle for some mass produced drivel from Toys“R”Us Amazon, they’ve got some of the most thoughtfully engineered and built toys and gadgets on the planet. After all, there’s no way any hacker worth their salt is going to give anything less than 110% for their own child.

A case in point is this RGB star nightlight that [Unexpected Maker] built for his children. The star itself is simple enough, just a basic …read more

Simple RC to USB Interface

With the radio control hobby arguably larger now than it ever has been in the past, there’s a growing demand for high-fidelity PC simulators. Whether you want to be able to “fly” when it’s raining out or you just want to practice your moves before taking that expensive quadcopter up for real, a good simulator on your computer is the next best thing. But the simulator won’t do you much good if it doesn’t feel the same; you really need to hook your normal RC transmitter up to the computer for the best experience.
