TS100 oscilloscope hack

Befinitiv wrote an article describing his modification to turn a TS100 soldering iron into an oscilloscope: As you can see in the video, you can use the soldering tip as your measurement probe. Coincidentally, a soldering iron has already a pretty good form factor for an oscilloscope. Here is a still picture of a UART waveform […]

An almost-GHz active differential oscilloscope probe (Part 3)

Christer Weinigel wrote a series of three posts about how he built a active differential scope probe which is usable up to about a GHz: This is part three of a series about building a active differential oscilloscope probe.

Software Spectrum Analyzer for the Rigol 1000 series oscilloscopes

rheslip writes: I came up with this idea after seeing Farhan Ashar’s spectrum analyzer design which uses some of the same bits and pieces I used in the Simple Scalar Network Analyzer. Farhan’s is a classic heterodyne SA design – the addition of mixers and filters in front of the power detector makes the analyzer […]

Yet another laser oscilloscope

Kerry Wong writes: You can generate some pretty amazing patterns by shining a laser onto a mirror mounted on a vibrating speaker cone, a lot of people have experimented with this kind of laser show. But how about building a true laser oscilloscope that is capable of displaying signals? In this post, I will show […]

Steve Schuler over at Science2.0 published a new build: A laser oscilloscope using Lego, littleBits, Erector set, and the Kano Computer Build a laser oscilloscope using Lego, littleBits, Erector set, and the Kano Computer. In honor of The International Year of Light I’ll demonstrate how use the Kano computer to drive a littleBits motor with an […]

DIY active differential probe characterization

An 1GHz active differential probe project by Daniel Kramnik: This project was an ultra high input impedance (0.5pF||30MΩ or better) high bandwidth differential oscilloscope probe designed, built, and revised over the course of two weekends for the 2014 MakeMIT hardware hackathon. It can be built for about $30 in parts, plus the cost of etching or sending […]

DIY USB-Oscilloscope in a matchbox

ajoyraman posted a tutorial on how to make a DIY USB-matchbox oscilloscope,  an instructable here: In order to economize on the cost of an enclosure while still providing an aesthetic unit the Aj_Scope2 is enclosed in a large size cardboard matchbox enclosure. The USB connection to the PC is on one end while the Audio-Jack […]

PC storage oscilloscope and logic analyzer

From the comments on our earlier USB oscilloscope with signal generator post, here’s a PC storage oscilloscope and logic analyzer by Nerd Ralph: A logic analyzer is a useful tool when working with micro-controllers, but when compared to the price of Arduino compatible boards, they are expensive. While the ability to decode different protocols is a […]

USB oscilloscope with signal generator

Specifications: Price: 20$ Frequency: 2-20000HZ Resolution: 16 Bit Voltage range: +-7V / with probe +-70V Channels: 2 X-Y Mode Signal generator: Sine, Square, Triangular and Sawtooth […]

Silver bullet oscilloscope IR receiver

The crew from AnalysIR have shared a simple technique for viewing the mark and space data from IR transmission on an oscilloscope. They call it the “silver bullet” method. The idea is to use a standard IR Led mounted into a BNC/RCA plug using a spare channel making an Oscilloscope infrared receiver. So we set […]
