Fresh hacks every day
Hackaday alum [Ian Lesnet] has been working in cahoots with a dedicated team of developers to produce the OpenBench Logic Sniffer. This caseless logic analyzer can operate at 100MHz and sample 32 channels at once. Better yet, a digital oscilloscope add-on is in the works. The pre-order comes in at $45, that's a lot of functionality for just a few greenbacks. We've embedded a demo video after the … [Read more...]
[Oliver] received the Telly Terminator as a gift and decided to take a closer look at it. This key fob has two buttons; one shines an LED like a flashlight and the other turns off televisions. Sound familiar? Yeah, it made [Oliver] think of the TV-B-Gone as well. He cracked open the case to find just a few components. The brain behind the IR signals is a Helios H5A02HP. Only a few pins are used … [Read more...]
Hackaday alum [Ian Lesnet] tipped us off about some reverse engineering of the HVR-1600, an analog and digital television encoder/tuner. The project was spawned when [Devin] noticed his Hauppauge HVR-1600 didn't tune channels in Linux quite as well as it did in Windows. He had a hunch this was due to improper initialization settings for either the tuner chip or the demodulator. To fix this he … [Read more...]
[Jack Gasset] sends in the logic analyzer he's been working on. The logic analyzer boasts an impressive array of features, it can sample 32 channels at 100MHz, 16 channels at 200MHz, SPI, UART, I2C and more. The analyzer's maximum sample size is 4K for now, and it supports RLE to reduce the memory consumed. The analyzer connects to a java client on a standard PC via USB. The open source hardware … [Read more...]
A logic analyzer records bus communications between two chips. If you've ever had a problem getting two chips to talk, or wanted to reverse engineer a protocol, a logic analyzer is the tool you need to spy on the bus. The Logic is a USB logic analyzer with eight channels and sampling rates up to 24MHz. Among hobby-level logic analyzers, the Logic has a good mix of features and decent sampling … [Read more...]
Now that we listen to MP3s, and watch XVIDs or x264s, a computer is the entertainment center in at least one room of most homes. Unless you have a special HTPC, though, you're probably stuck using the keyboard to pause, change the volume, and fast-forward through annoying Mythbusters recaps. PC remote control receivers range from ancient serial port designs (who has one?) to USB devices not … [Read more...]
In a two-part series called "PS3 Fab-to-lab" on IBM's awesome developerWorks website, [Lewin] explains how to use the Cell Broadband Engine in a PS3 to create an audio-bandwidth spectrum analyzer and function generator. The set up consists of Yellow Dog Linux, an NTSC television, and an external USB sound card to provide the inputs of the spectrum analyzer and the outputs of the function … [Read more...]
