He explains how his software approach is to disable all interrupts, and put the microcontroller into a tight polling loop to read data from the ADC as quickly as possible. Especially since there’s a good chance you can build the thing out of parts from the junk bin.Įven if you’re not looking to build your own version of the Arduino-powered scope describes, his write-up is still full of fascinating details and theory. But if you’re doing some quick and dirty diagnostics in the field, that might be all you need. ![]() is very upfront about the limitations of this DIY pocket scope: it can’t hit very high sample rates, and the display isn’t really big enough to convey anything more than the basics. Consisting of little more than an Arduino Nano and a OLED display, the cost comes out to less than $10 USD for a decent DSO that’s about the size of a matchbox.īut not a great one. Not only was it an excuse to deep dive on some interesting engineering challenges, but it ended up bringing the price even lower than turn-key models. While there are a number of very cheap pocket digital storage oscilloscopes (DSOs) on the market, decided he’d rather spin up his own version using off-the-shelf components. But if that’s still a little too rich for your taste, and you’re willing to skimp on the features a bit, you can get a functional digital oscilloscope for little more than pocket change. Even a fairly feature rich four channel scope such as the Rigol DS1054Z only costs about as much as a mid-range smartphone. It’s a critical piece of gear for reverse engineering devices and protocols, and luckily for us they’re as cheap as they’ve ever been. There’s little question that an oscilloscope is pretty much a must-have piece of equipment for the electronics hacker. Posted in hardware, Tool Hacks Tagged Digital storage oscilloscope, diy oscilloscope, dso, oscilloscope, ST7735, stm32, STM32F4 All in all, it’s a strong contender in the “simple and powerful DIY scope” arena, before this, we’ve seen one built with an Arduino Nano, and one with a Pi Pico. It’s also, quite possibly, a better scope than the red “soldering kit” ones we’ve seen online. This build could easily take up a honorary “temporary turned permanent” place on your bench, thanks to its McGyver-esque qualities. Are you a bit lost in how oscilloscopes work? has an explainer for you, too! Of course, the simple frontend results in the input range being from -3.3 V to 3.3 V, but as you could guess, this is exactly the kind of project where you could tweak the resistors and even upgrade it later on. So after jumper-wiring the LCD and three push buttons to your BlackPill, you’re golden. The front-end is super straightforward to find components for and assemble, a few opamps and resistors is all you need. You really don’t need much in the way of parts, a protoboard will do, though you can also etch or order your own PCBs. It’s hard to overshadow just how easy this scope is to build, use, and hack on. Not just that - it can even stream data to your computer, in a format compatible with the TekScope software! Saftari Translated by Taufik Masjhur This post was originally published on in Bahasa Indonesia language.Would you like to have a small digital oscilloscope? Do you have a spare BlackPill (STM32F401) board and a TFT display laying around? presents us with a simple and educational digital storage oscilloscope design that barely needs any components for you to build one, and it’s packed with features just like you would expect from a self-respecting open-source project. For safety of your Laptop, you can use cheap USB SoundCard (under $5). The value of Potentiometer could be increased up to 100K Linear, for the use of Oscilloscope with an input of above 5 volt. The value of 22K Resistor could be increased up to 820K Ohm for the use of Oscilloscope with an input of above 5 volt. This Oscilloscope has a frequency range of: 20Hz to 20 kHz (complying with the Soundcard capability). This Oscilloscope could be used for a maximum input voltage of 5Volt. Sample of close-to-perfection voltage signal without noise. ![]() The Oscilloscope is ready for use!! Below are several voltage signal tests, among others signals from mobile phone charger, laptop charger, battery, etc. This application is 14-day Trial, could be purchased at a price of not more than (US $9.95). The unit is ready, Plug the Stereo Jack into LINE-IN/MIC Get OSCILOSCOPE APPLICATION The application is ZELSCOPE, free download at. ![]()
