When the time comes to go to the store and pick up those chocolates you always get your mother for valentines mother’s day, why not spice them up a little with some LEDs? [Dmitry] shows how you can easily add some flashing lights to the packaging without really modifying it. He’s using an ATtiny13 which [...]

In the world of your dreams, you can build an entire world, an entire universe, an entire society governed by your every whim. While lucid dreaming you are a god in your own mind, free to create or destroy at will. You can train yourself to recognize when you are dreaming, but sometimes a little technological help can [...]

Falling on the heels of some fabulous ’lets see what we can emulate on an AVR’ builds we’ve seen, [Dimitri] emulated an ARM Cortex-M0 on an 8-pin ATtiny85. The emulator is written entirely in AVR assembly. Unfortunately, the instruction set of ATtinys don’t have a multiply instruction, so that had to emulated in a separate piece of code. Even [...]

[Pete Mills] recently bought himself a motorcycle, and as people are known to do, they start trying to scare him with gruesome stories of cycling accidents once they hear about his purchase. While he tries to shrug them off as people simply not minding their own business, something must have resonated with him, because he [...]

We may be showing our age here, but we have no idea what a ‘poke’ on Facebook actually means. Whether it’s the passive-aggressive manifestations of online stalkers or an extension of  the ‘like’ button, all we know is [Jasper] and [Bartholomäus] built a machine that translates virtual pokes into our analog world.

[wejp] picked up an IKEA SPÖKA night light, but he wasn’t entirely impressed with its functionality. Pressing the top of the ghost’s head causes it to cycle through a few colors, and pressing it a second time locks it into displaying the current color until its tapped again.

Like many businesses out there, [Joonas Pihlajamaa’s] employer requires him to change his password every few months. Instead of coming up with a complex, yet easy to remember password again and again, he built a small USB device to do the work for him. He dismantled an old USB memory stick, fitting it with an [...]

[John De Cristofaro aka Johngineer] uses various ATmega microcontrollers in his electronics projects, but he finds himself reaching for an ATtiny2313 or ATtiny4313 more often than not. He got tired of having to wire up pin headers, capacitors, and the like each time he started a project, so he spent some time designing an easy [...]

As a senior in high school, [Owen] has been waiting to hear from the colleges he applied to for months now.

Function generators are a handy bench tool to have around, and while you can usually cobble something together that works, it is much more handy to grab a device when you need it.

[Quinn Dunki] got some free stuff from Element14 to evaluate, including this Mircrochip WiFi module.

When the Regency TR-1 transistor radio came out onto the market in the 1950s, it was hailed as a modern marvel of microelectronics. With only four transistors and a handful of other components, the TR-1 was a wonder of modern engineering. [Sprite_tm] may have those old-timers beat, though. He built an FM transmitter with the lowest [...]

Behold this ATtiny85 based EEPROM programmer. It seems like a roundabout way of doing things, but [Quinn Dunki] wanted to build to her specifications using tools she had on hand. What she came up with is an ATtinyISP USB programmer, pushing data to an ATtiny85, which then programs an EEPROM chip with said data. The [...]

[Phil’s] parents grow their own organic food, but the harsh Ukraine winters make storing it a difficult proposition.

[Steve] has an older third generation VW Golf, and as those who have owned one surely know, the beloved VR6 engine is wonderful but finicky.

[Mike Shegedin] makes full use of an 8-pin microcontroller with this ATtiny13-based dice project.

Servo8bit is a library for AVR microcontrollers that allows you to drive servo motors without the need for a 16-bit timer. Obviously, this is quite useful for smaller chips that only have 8-bit timers and it is specifically targeted at the ATtiny45 and ATtiny85 microcontrollers. The library offers 256 steps of resolution, and can drive up to [...]

Okay, you’ve got a six-pin microcontroller with 1k of program memory, 32 bytes of SRAM, and it can’t be programmed using an In-System-Programmer. Do you think you can use it to develop a game?

After [trandi] got his hands on a cheap R/C helicopter he realized the difficulties in actually flying a remote control helicopter.
