The SmartScope designed by the young Belgian company LabNation is — to our knowledge — the only oscilloscope that works with all popular operating systems: Windows 7/8, Linux, OS X, iOS (jailbroken) and Android 4.0+. So the software can run on a standard PC or laptop, but also on a tablet or smartphone. The control interface is specifically designed to operate with touch-screen or mouse and is equipped with various software decoders (such as I2C and SPI) for decoding digital signals.

The Smart Scope hardware consists of a small metal housing (for good protection) with the front two full BNC connectors for analog inputs, and at the rear a 16-pin header which has 8 digital inputs for the logic analyzer. Four digital outputs and an output for the built-in arbitrary waveform generator (AWG) are available. The sampling frequency of the analog and digital inputs is 100 Msamples/s, the maximum data rate of the AWG is 50 Msamples/s.

D4p0up shared his open source soundcard oscilloscope in the project log forum:

Here is a tool that might help some of you in your DIY activities : WaveWatch, a soundcard oscilloscope 100% made with Processing.
I’ve just released the 1.3 version, making it a very credible, user friendly and totally open source alternative to existing soundcard scope systems, so that it’s worth sharing it !
It’s got all the features you’d expect from a standard scope,
dual channel,
configurable Triggering (single/Auto),
time and voltage measurement,
frequency calculation,
markers with delta calculation
voltage calibration

nScope is a USB-powered oscilloscope, function generator, and power supply that turns any laptop into an electronics workbench.

nScope is a usb-powered device that plugs into an electronics prototyping breadboard. nScope’s main function is an oscilloscope. Much like a multimeter, an oscilloscope measures voltages in a circuit. But unlike a multimeter, it stores voltages over time and displays them in a graph. This makes nScope much more useful for observing sensor signals and dynamic circuits. nScope’s software interface maximizes the graph space, and provides controls for setting the measurement speed and range.

I am experimenting with RF and IR signals in various frequencies and had some trouble with the receivers and needed to see what kind of signal i was receiving. I cannot afford a real oscilloscope but i knew about the older Arduino oscilloscopes.

After trying many different versions of code and tutorials, I was unable to get a single one to work, and all the tutorials and guides around was 2-3 years old. Not sure if it is the IDE or the actual hardware that has changed in such a way that it didn’t work anymore.

I finally found a working oscilloscope from a Japanese website, (linked below) and a working TFT screen library, meaning i could read the various signals received.

Just a bit of fun…I try use an oscilloscope to measure / calculate the speed of sound. I also conduct a hearing test during the video.

by Tomasz Ostrowski @ tomeko.net:

Extremely cheap low-speed PC/USB oscilloscope with STM32 (STM32F042) microcontroller.

Announced in January 2014 Cortex-M0 microcontroller family that features crystal-less USB FS device allows to cut noticeable part of BOM when building oscilloscope/recorder similar to miniscope v2c/v2d. STM32F042F devices are interesting in particular because of small and friendly TSSOP20 package with minimum number or power lines.

STM32F042F4 devices feature USB bootloader (DFU), single 1MSps ADC (so single channel sampling would be preferred to avoid crosstalk issues), 16 kB FLASH memory (~2 times more than needed) and 6 kB RAM.

Pico Technology has announced that its 3000D Series oscilloscopes launched in October last year now offer deeper memory. This comes on the back of last November’s release of beta drivers for Mac OS X and Linux operating systems for their range of oscilloscopes and data loggers adding to the existing Windows driver. This makes them suitable for use with the BeagleBone Black and Raspberry Pi development boards.

All scopes in this range feature deep memory, allowing high sampling rates to be maintained even at slower sweep speeds for capturing long waveforms in fine detail. Sampling at 1 Gsample/s it can capture a 500 msec waveform (half a billion samples) while hardware acceleration takes care of smooth display updating.

The high definition (HD) mode increases the vertical resolution of the R&S RTO and R&S RTE oscilloscopes to up to 16 bits – a 256-fold improvement over 8-bit resolution. Waveforms are sharper and show signal details that would otherwise be masked by noise. Users benefit from even more precise analysis results.

High definition describes the capability of R&S RTO and R&S RTE oscilloscopes to work with applications for which a high vertical resolution is essential. This is especially the case when low-voltage components on a signal that also exhibits high-voltage components need to be analyzed in detail. One example is the characterization of switch mode power supplies. The voltages across the switching device must be determined during the off and on times within the same acquisition. Because the voltage variations during these switching cycles can be several hundred volts, a high resolution is essential for the precise measurement of small voltage components.
