The only major downside with this specific project is that the high-powered laser can be harmful to humans as well. The control system as well as the neural network and machine learning are hosted on a Raspberry Pi and Jetson Nano which give it plenty of computing power. Once a mosquito is detected, a laser is aimed at it and activated in order to “thermally neutralize” the pest. The device uses a neural learning algorithm to identify mosquitoes flying nearby. Various mosquito deterrents have been invented over the years to solve some of these problems, but one of the more interesting ones is this project by which attempts to build a mosquito-tracking laser. While they serve as a food source for plenty of other animals and may even pollinate some plants, they also carry diseases like malaria and Zika, not to mention the itchy bites. Mosquitoes tend to be seen as an almost universal negative, at least in the lives of humans. But if chasing mosquitoes with low-tech gadgets isn’t for you, there’s always lasers and good old torture, although those can’t be repurposed to do some hardware fault injections during the winter months then.Ĭontinue reading “Bug Zapper Counts And Serenades Its Victims” → Posted in Misc Hacks Tagged attiny, bug zapper, DFPlayer, Digispark, mosquito, mosquitoes, pest control Have a look at the video after the break for some quick demonstration.Īll in all, this is a delightfully absurd modification that almost screams for an ESP32 to enable multiplayer mode as next iteration. He distinguishes between two different levels here and maps them as normal kill and monster kill for the big zaps respectively, playing different sounds for each. Of course, with these operation voltages, it would be difficult to detect activity on the high voltage side more than once, so went with current sensing instead. A new 3d-printed cover provided enough space to house all the components, including a charging circuit as he swapped the original two AAA batteries with a rechargeable one, which gave a bit more power for the display.

After taking the zapper apart and doing a bit of research, he put theory into practice using a Digispark Pro board containing an ATtiny167, the DFPlayer module for playing a set of WAV files, and an ambitious four digit 7-segment display to keep track of the “score”.

The initial thought was that there has to be a way to detect when a mosquito hits the mesh, and use that to trigger further events - in ’s case play a sound file and increment a counter.

saw big potential for some additional gamification here, and decided to equip his zapper with a kill counter and matching sound effects. A satisfying way to deal with them is to send them off with a bang using one of those racket-shaped high voltage metal mesh bug zappers. Not many creatures are as universally despised as mosquitoes, whether it’s the harmless kind that, at worst, makes you miss winter, or the more serious ones that can be a real threat to your health.
