Firefly – an annoying little thing

Here’s a tiny pcb that produces an annoying sound using a piezo buzzer and a ATtiny13 microcontroller.

It uses an LED, piezo buzzer, ATTINY13 Atmel microcontroller, a very small amount of Arduino code, and a coin cell battery that should last about a week.

Battery life could be improved, with longer sleep times. The device has but one function: sleep, then wake up periodically and blink and chirp, then go back to sleep.

How To Program ATtiny13/ATtiny13a using Arduino IDE

Despite ATtiny series is considered extremely cheap and useful, still there is a lack of projects and tutorials about it. In this tutorial, you will learn how to start building applications using ATtiny13 microcontroller programmed using Arduino IDE.

First of all, ATtiny13 is a low-power CMOS 8-bit microcontroller based on the AVR enhanced RISC architecture. By executing powerful instructions in a single clock cycle, the ATtiny13 achieves throughput approaching 1 MIPS per MHz allowing the system designer to optimize power consumption versus processing speed. After the acquisition of Atmel by Microchip, the new ATtiny13 is still in production.

Tic-Tac TV Remote Jammer


by DangerousTim @ instructables.com:

That moment you take your eyes off the TV remote for just a second, because of which it falls into the hands of your annoying sibling. Yes, fighting for control over the TV is a daily struggle for many. But the TV Remote Jammer shown in this Instructable, will make everyone else stop dead in their tracks.

This Remote Jammer circuit, in the disguise of an inconspicuous TicTac Box, sends a constant signal to the TV receiver that interferes with the signal from the TV remote. This means that when the Jammer is on, your TV remote CANNOT be used to change channels. It practically blocks all signals from the remote.
