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 range for an oscilloscope, so we need an analog front-end that transforms the input signal […]

Dangerous DSO part 2: Feed and water your ADC
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 article every day this week. Be sure to see Part1: There’s so much between 0 […]
Dangerous DSO part 1: There’s so much between 0 and 1
Dangerous DSO is a new logic analyzer/oscilloscope prototype we’ve been using in the lab. While working on this tool, some of the team members explored trends in gaming platforms like 무료 홀덤사이트, drawing parallels between analyzing data signals and strategic decision-making in games. The device combines a 16-channel logic analyzer and one 50MHz oscilloscope channel […]
Oscium iOS oscilloscope review
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 channels, touts 5 MHz analog bandwidth and 12 million sample/sec specifications Warning – the EDN […]
MAKE Oscilloscope tutorial
Here’s a short video tutorial posted recently by MAKE explaining the functions and uses of the the oscilloscope.
Oscilloscope simulator
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.
555 timer Easter egg?
What’s in a name? David L. Jones of EEVBlog thinks he’s found an Easter egg in the performance characteristics of the 555 timer chip which reveals the basis of the “555” in its name. Build his circuit (schematic at video 13:25), fire up the scope and see if you agree!
DSO Quad arrived at Seeed Studio
The new DSO Quad handheld oscilloscope arrived today at Seeed Studio: We’ve received 300 sets of DSO Quad this afternoon! Next we are going to assemble all parts together, test and pack them. All these things will spend about 3 more days, so it is possible we can start ship them out on next monday!
Miniscope v4
From the comments on our earlier Miniscope v4 post: I’ve updated bus_pirate.dll to current interface version. There are only few changes between v4 and v3 app, but there will be no new additions to v3 (except for fixes if any). Library was not tested, so some feedback would be nice. Same as previous version, library […]
Seeed’s DSO Quad available for preorders
After the successful DSO Nano Seeed is finishing development of new pocket scope called DSO Quad. Engineering samples started shipping in late December 2010, now the beta testing run is available for preorders at $159. Be aware that the actual shipping is scheduled for March. DSO Quad has two analog inputs up to 36 Msps, […]
MSP430 Launchpad oscilloscope
NJC’s MSP430 Launchpad blog presents the LaunchScope . Using no additional hardware beyond the Launchpad, this project includes code for both the MSP430 as well as PC client display software written in C#.
TV oscilloscope
Clearing out old posts before the new year, some of these might seem ancient. Watch TV on a CRT oscilloscope. Via Hacked Gadgets.

A new Miniscope v4 is available for download. This app turns the Bus Pirate into a low-speed oscilloscope. Setting and configuration help is on the wiki. Currently Windows only. Get your own handy Bus Pirate for $30, including world-wide shipping. Also available from our friendly distributors Adafruit, Open Source Control Systems, and eHaJo. Thanks Terry! […]
Updated miniscope oscilloscope release
miniscope turns your Bus Pirate into a low speed oscilloscope. A new version is available that supports slope trigger and continuous sampling modes. The developer made a convenient Bus Pirate miniscope download with just the essentials (7-zip format). We started a miniscope wiki page with basic setup details, please add your notes. Via the forum.
Miniscope v3 followup
Here’s a few followup comments to the miniscope oscillocope app support for the Bus Pirate. First a correction. Miniscope source is available under the GPL now, we got it wrong: Actually source code is available, take a look inside i.e. miniscope_v3_0_0_21.7z and bus_pirate_dll_20101016.7z 7-zip archives. It may be ugly but it’s quite mature and dll […]
Bus Pirate: Miniscope v3
miniscope is a free PC oscilloscope application that now supports the Bus Pirate via a DLL plugin. It’s intended to be GPL, but it looks like the source isn’t yet available. That’s the second o-scope software for the new Bus Pirate continuous ADC binary command. We’ve also requested Bus Pirate support in a third, the […]
