Fresh hacks every day
We must be walking past the wrong dumpsters because we certainly haven't encountered equipment like this just waiting to be salvaged. [Shahriar] found an HP 8648C Synthesized Signal Generator while he was 'dumpster diving' and set out to fix the malfunctioning lab equipment. He posted a 1-hour video on the project, which you can find embedded after the break. The actual fix happens in the … [Read more...]
A signal generator is a handy bit of kit and with the right components, it's pretty easy to build one. Fabricating a proper signal generator probe is another matter entirely. [Frank]'s DIY signal generator probe does exactly what it claims to, and is very cheap to boot. After [Frank] made a simple signal generator with a few parts he had lying around, he needed a probe. Not wanting to deal with … [Read more...]
One thing we learned by watching [Alton Brown] on all of those Good Eats episodes is that a multitasker is way better than a unitasker. [Joost] is thinking along the same lines by taking a fantastic tool and adding a useful function to it. His software project turns a USB Saleae Logic Analyzer into a signal generator. There are already a multitude of reasons to own one of these fantastic … [Read more...]
[Debraj] needed a simple signal generator for a project he was working on, but didn’t have one handy. He found that the easiest and cheapest way to get clean, reliable signaling was by using something that was already sitting on his desk - his PC. He found that the tone generator built into Audacity was quite useful, at least for generating waveforms at less than 20 KHz or so. Upon plugging … [Read more...]
[Vassilis Papanikolaou] took a good thing and made it better with some design upgrades to this AVR based signal generator. We looked at version 1.0 of this tool back in 2006 and since then it saw an upgrade to 2.0. But [Vassilis] wanted to take things one step further, with a compact single-sided PCB. What you see above is the beautiful result of his work; a professionally made board that is … [Read more...]
