Many devices use infrared (IR) as a signalling medium like, for example, RGB LED strip controllers
modules and some TV controllers. Often times these signals aren’t meant for secure applications which means the functionality can be reproduced by simply replaying back the received signal verbatim. Sometimes, enterprising hackers want to reverse engineer the IR signals, perhaps to automate some tasks or just to get a better understanding of the electronics we use in our everyday life. To help in this effort, [dilshan] creates an open source hardware IR cloner device, capable of snooping IR signals and retransmitting them.
The IR cloner is a sweet little IR tool that can be used to investigate all sorts of IR signals.
In addition to the source code and design files, [dilshan] has also taken care to create detailed documentation as an addendum to the video on assembly and usage. Continue reading “Your Own Home IR Cloner”
If you’ve got a smartwatch on your wrist, chances are you’ve also got a device nearby that links up with it. Most modern watches will happily sync with Android devices or iPhones, and some will also talk to Windows PCs. But what if you’re running an alternative OS? Something like, say, Commodore BASIC? In that case, you might want to check out [Nick Bild]’s latest project, which lets you to sync your smartwatch to your Commodore 64.
Sadly, you can’t just use any old smartwatch: the project is an extension of [Nick]’s Commodore 64 Smartwatch that we featured earlier. This watch can run Commodore 64 programs thanks to a custom software stack, but like most typical smartwatches also includes an accelerometer that counts your steps. Syncing the step counter to your computer is straightforward: after you come home from your daily run, you simply tap “sync” on the watch, enter
LOAD"SYNC.PRG",8,1 on your Commodore 64, and the computer will show your total step count.
The C64 watch communicates with the host computer through a built-in infrared port. The classic Commodore computers don’t have an IR receiver, so [Nick] built one himself using an Arduino Micro hooked up to the C64’s User port. A custom program reads out the data and shows the step count on the screen.
Although the feature set of this app is a bit limited, [Nick]’s project demonstrates how the good old Commodore 64 can still perform useful tasks in today’s world. Not that we needed much reminding: after all, we’ve even seen it run AI applications using TensorFlow Lite.

We recently published an article where someone apparently controlled their TV by simulating a remote with merely a lighter and a sheet of paper. The paper had a barcode like cutout for a supposed “Universal Standby Signal”. The video rightfully attracted a substantial crowd, some awestruck by its simplicity, others sceptical about its claims.
Coming from some generic “Viral Life Hack” production house, the characteristic blare of background music, more suited to an underground rave than a technical video, certainly did not do it any favours. As any moderately experienced campaigner would know, modern televisions and remotes have been carefully engineered to prevent such mishaps. Many of us at Hackaday, were under the impression that it would take something slightly more sophisticated than a fluorescent-bodied lighter and a crisp sheet of A4 to deceive the system. So we tested it out. Our verdict? Unlikely, but not impossible. (And we’re pretty sure that the video is a fake either way.) But enough speculation, we’re here to do science.

The evolution of the mere beetle has transformed from organic matter into robotic gears, circuits, and wires. This Cyberbeetle project was born during an open culture hackathon in Berlin throughout a few months time period. The event was called Coding for Vinci and was held from April into July 2014. The project used an Arduino and combined openly licensed biology related pictures and sounds from the museums in the area in a fun and playful way.
[Kati] and [Tomi] based the design on a gorgeous Chalcosoma atlas beetle species which was found in insect box scans that were taken from a nearby museum. The cool thing about this project is that the Cyberbeetle that [Kati] and [Tomi] created has its own hi-tech insect box with various special features. For instance, when the box was rotated on its side, small doors were revealed that when opened unveiled a tiny home theater system with a hi-definition flat screen, audio system and infrared communication. Inside the horn of the Cyberbeetle was an infrared receiver, which allowed the creature to interface with its TV program when it started. Music videos as well excited the robotic insect.
The project was awarded the “Funniest hack” prize during the hackathon. And a video of it can be seen after the break:
