Patrick Cambria posts this simple oscilloscope project using a Picaxe-08M microcontroller and a potentiometer. The Picaxe is programmed in BASIC and the entire MCU program follows: main: READADC10 1,B0 SERTXD(#B0,10) goto main The output from a potentiometer voltage divider is … Read more
András Veres-Szentkirályi is part of the H.A.C.K. hackerspace in Hungary. They acquired an affordable, slightly used UNI-T UT2025B digital storage oscilloscope. He wondered what useful information could be gained from sniffing the USB port using Wireshark on a Linux box. … Read more
David from Nut&Bolt has written a short overview of affordable oscilloscopes (sub 400 euro) on his website. Via the contact form.
Csaba Bleuer writes:”I bought a Siglent SDS1102CM oscilloscope, and since there are no reviews about it on the net I have written one.” Check out Csaba’s well illustrated review on his website. Via the contact form.
A RC Wien Bridge oscillator outputs a pure sine wave. The frequency depends on the resistor-capacitor combination in the oscillator. Embedded Eric built one using instructions from “Analog Circuit Design“: I have been slowly reading through Jim Williams “Analog Circuit … Read more
Sqkybeaver let us know Sparkfun now carries a scope similar to the one he reviewed. It is a two channel 100MHz digital scope with 500MSa/s real-time sampling rate. Saving waveforms to a USB flash drive is available, as well as interfacing with the computer over the USB port. The … Read more
Pong on an oscilloscope. Check out Kevin’s epic original project over at Hack a Day: Want to play Pong on your Oscilloscope? I always have! …The code is a nice mixture of ArduincoreGCCish (I am sorry, still learning), and includes … Read more
hlipka made a logic analyzer with 2 oscilloscope channels that uses a Cypress PSoC chip. It works with SUMP clients like Open Logic Sniffer. Goal of this project is to develop a combination of 2-channel oscilloscope with a 32-channel logic … Read more
Ros.org presents this project tutorial demonstrating that a simple oscilloscope can be implemented using the Arduino. They write: In this tutorial, we will be making a poor man’s oscilloscope using the Arduino’s ADC (analog to digital converter) and rxplot. We … Read more
Squonk has some useful links if you want to build your own scope: A nice HDL example of an oscilloscope using a FIFO and trigger A 100 MHz input stage A firmware development/improvement for the DSO “Welec 2000a- series” The … Read more
bearmos found a multifunction MSO: …it appear to be an MSO, with an OLED display, in a DIP package, for $35 The Xprotolab is the first mixed signal oscilloscope with an arbitrary waveform generator in a DIP module. It measures … Read more
Dangerous DSO is a new logic analyzer/oscilloscope prototype we’ve been using in the lab. It combines a 16 channel logic analyzer with one 50MHz oscilloscope channel with +/-10volt DC range. The combined tool shows what your signal does between 0 … Read more
It’s the last day of our week-long Dangerous DSO adventure. Yesterday we simulated the analog front-end and found a few changes to test. First, we’re going to increase the ADC buffer gain to 2. That should make vertical offset adjustment … Read more
Yesterday we covered the Dangerous DSO analog front end. This circuit divides our +/-10volt input to +/-0.5volts, and re-centers it between the 2volt and 3volt range the ADC can measure. Today we’ll simulate the circuit to get a better feel … Read more
Yesterday we looked at how the Dangerous DSO analog to digital converter works, and it turns out to be a pain in the butt. It only measures a 1volt (1Vp-p) range between 2volts and 3volts. That’s not a very useful … Read more
Dangerous DSO is a new logic analyzer/oscilloscope design we’ve been using in the lab. This is not a finished project, it will not be produced. We’re posting our current progress to get some feedback. Look for a new Dangerous DSO … Read more

EDN reviewed the Oscium logic analyzer and oscilloscope for the iPhone/centiPad. It uses the Cypress PSoC 3, which is a CPU+FPGA hybrid. Cool tech, but too closed and pricey for us: The $297.99 device comprehends one analog and four digital … Read more
Here’s a short video tutorial posted recently by MAKE explaining the functions and uses of the the oscilloscope.
There is an interesting oscilloscope simulator , not much is known about the authors, other than the brief description of the reasons they chose to simulate this particular scope. Give it a try and tell us what you think.
