@0x2B2B tweeted, “Case for my OLS, laser cut at @RazorLAB. Design file in post 2byt, make your own! Why the case? Well, being the fan of OSS/OSH (that’s; Open Source Hardware :) that I am, this was a nice, affordable entry into the market of Logic Analysers. It’s always great having bare P.C.B.s because come […]

OpenBench Logic Sniffer ported to Pipistrello LX45
mkarlsson ported the Open Bench Logic Sniffer code to run on Pipistrello LX45: FYI, I have ported the Demon 3.07 code to Pipistrello LX45 FPGA board with the following changes: 1) The sample buffer size is increased by a factor of 8 from 24kB to 192kB 2) The interface is changed to serial (Pipistrello uses a FTDI […]
Logic Analyzer costs little, performs well
Adam Carlson over at Microcontroller Central wrote a short review of the OpenBench Logic Sniffer: The OLS, the lowest-cost option, is both open-source hardware and open-source software. This is the product of a cooperative effort between Dangerous Prototypes and the Gadget Factory. To me, being open-source is not necessarily a plus. While it is great […]
Measuring hexacopter rotor speed with Logic Sniffer
Philip Peter has made a somewhat unconventional use of the Open Bench Logic Sniffer. Recently we suspected that one motor of our hexacopter had been damaged in a crash. Since removing the motor requires almost the complete disassembly of the copter I started thinking of ways to test the motor in place. In this article […]
Logic Sniffer client: New signal display component
Jawi uploaded a preview of the new signal display component for the Logic Sniffer application. OLS is a java client designed to run on multiple platforms including Windows, Linux, and Mac. You can download this mock from ols.lxtreme.nl, which should run on Windows, Linux and OSX (only the latter is heavily tested ;)). A list […]
Logic Sniffer: Vote for signal display annotation style
Jawi is developing a new version of the Logic Sniffer client app. He’s currently deciding on which style to use for annotation. Help him out by casting your vote in the forum. The OLS client supports the annotating of data to present additional information along with the signal data. For example, many of the decoding […]
Logic Sniffer: add-on board
Madworm made a Logic Sniffer add-on board, it has dip switches to allow users to pull up or down any of the 16 channels. It also has jumpers for selecting different pull up voltages. He is currently working out which resistors would work best for his purpose. Via the forum.
Yet another Logic Sniffer case
David made 8 Logic Sniffer case designs for a project he calls Yet another Logic Sniffer case: I’ve noticed a number of Open Bench Logic Sniffer case designs on the Dangerous Prototypes site. I recently decided to design the yaobls (Yet Another Open Bench Logic Sniffer) case in order to gain some experience with the […]
Open Bench Logic Sniffer review
The Longhorn Engineer liked the OLS so he posted this video review. He also has posted a video demonstrating how to upgrade the OLS firmware. Check it out! Thanks, LonghornEngineer! Get your own Logic Sniffer for $50, with free worldwide shipping.
Maker Faire 2011: Logic Sniffer
Connect an OLS to a device and record the output. Jawi’s OLS client is intuitive and easy to use.
New signal display component for Logic Sniffer client
Jawi released a preview of the new display component for the Logic Sniffer client: I’ve been working on an improved component for the display of captured signal data from the Logic Sniffer for some time now, and wanted to share the current results with you guys. Reasons for rewriting the component can be found on […]

Logic Sniffer RLE update
rasmus has another RLE update for the Logic Sniffer. The finish command is now 0x05. Timer removed in favor of the finish command. The code has been optimized and made easier to read. Two independent updates of the logic analyzer core are currently underway in the forum. There’s also updates to the Verilog version we […]
Logic Sniffer RLE update new version
There’s a new version of rasmus’ RLE update for the Logic Sniffer. This version has fixes for 8 and 16bit RLE, and new ways to dump RLE samples immediately. The finish now feature is probably something that the user wants. Responsiveness is good. You might think you want a 60 second timeout, but then you […]
Logic Sniffer update tool testers needed
robots posted a brand new multi-platform update tool for the Logic Sniffer. It updates both the firmware and bitstream from a single application: I am looking for volunteers to test it. Please just someone who has access to Bus Pirate, or other means of pic flashing. I have included several measures to protect the bootloader. […]
Logic Sniffer RLE fix test
rasmus posted an updated Logic Sniffer bitstream with a bunch of fixes to RLE: 32-bit (31-channel) RLE works as before. 16-bit (15-channel) RLE works (I think) but the client doesn’t support it yet. You’ll see the raw RLE data in the client. 8-bit (7-channel) RLE works with the same caveats. All RLE modes time out […]
Logic Sniffer test release 2.11
The Logic Sniffer is an open source logic analyzer. It’s designed to support the SUMP logic analyzer software at the lowest possible cost. This project is a collaboration between the Gadget Factory and Dangerous Prototypes. Jack posted Logic Sniffer bitstream test release 2.11 with bigger samples and RLE improvements: Extends memory depths from 8k and […]
Logic Sniffer upgrade procedure
This is an old version, see the latest version on the documentation wiki. The Logic Sniffer is an open source logic analyzer. It’s designed to support the SUMP logic analyzer software at the lowest possible cost. This project is a collaboration between the Gadget Factory and Dangerous Prototypes. The Logic Sniffer has two parts that […]
Ril3y’s new Open Logic Sniffer case
Ril3y sent photos of a new laser-cut case for the Open Logic Sniffer. This case isn’t available yet, but we’ll keep you updated. Ril3y also sells a popular laser-cut case for the Bus Pirate. You can order the OLS at Seeed Studio for $45, including worldwide shipping. Don’t forget that Seeed now has probe cables […]
