Inexpensive Sniffer reveals 802.15.4 packet details
Jon used TI’s SmartRF Protocol Packet Sniffer to reveal 802.15.4 wireless packet details: For the last several months my work with the XBee modules from Digi International involved using a logic analyzer to monitor the serial communications to and from the modules so I could measure the times between transmissions and view data streams as […]
AVR based 4 channel mini logic analyzer
This small 4 channel logic analyzer uses a ATmega microcontroller and a Nokia 5110 LCD. It’s able to capture signals only up to about 100Khz, but there is probably some room for improvement. This mini Logic analyzer is a tool for you to watch on LCD the logic transitions 0 or 1 of a digital […]

Logic Sniffer client version 0.9.5 final released
Jawi released the version 0.95 final of his Logic Sniffer client. It has these updates: Client now also runs on Java 7, but remains backward compatible with Java 6 Fixed issues #82, #81, #79, #77, #76, #75, #74, #70 and #40 Use PureJavacomm as experimental serial library instead of RXTX Major cleanups in Tool/Device API […]
Logic Sniffer 16-bit input buffer wing back in stock
Logic Sniffer 16-bit input buffer is back in stock at Seeed Studio. This accessory buffers the extra 16 I/O bits on the ‘wing’ header. The Open Logic Sniffer buffer wing in stock and shipping now for $15.
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 […]
New beta release of the OLS client
Jawi has been working hard on the Logic Sniffer OLS client. After the first beta release two issues were identified and fixed. He is now proceeding with the second beta release. If you’d like to help out, please download and test the OLS client for the Logic Sniffer. Via the forum.
Logic Sniffer: Hacking cheap RFID readers
Aaron decided to hack a cheap USB RFID reader, by using the Logic Sniffer to figure out the internal IC protocol. To make it useful for his projects he decided to hijack the internal bus that has the initial RFID decoding. After some poking around he was able to find the UART TX transmitting pin. […]

Logic Sniffer hack improves signal integrity
Tarloth designed this cool hack to improve signal integrity of the Open Bench Logic Sniffer. Instead of using the standard 1×18 pinheader, he used a dual row 2×18 header. One row is connected to the board, while the other is connected to GND. Unused signal pins are jumpered to GND using the extra header row. […]
Logic Sniffer: Bluetooth wireless connection
There’s an interesting discussion in the forums about enabling the Open Bench Logic Sniffer to work with Bluetooth. The consumer market is being flooded with cheap Android enabled tablets, and it seems like a good idea to use them with the OBLS to make a portable logic analyzer. Pppd is currently working with a BT […]
Logic Sniffer: RC transmitter module design debug
pppd created a removable RC transmitter module based on ATtiny25 with the Logic Sniffer. Annoyed by an uncomfortable RC transmitter design and its stick mode, pppd decided to build a removable RC transmitter. It works by converting the standard RC PPM into the IR signal used by the toy. But first he needed to reverse engineer the original using the […]

Logic Sniffer reviewed
My 2uF wrote a review of the Logic Sniffer: So far the OLS has helped me a lot to find the right timings, to tweak the delays between the data bits that are needed to make it work. It was a very easy process. Just look at the graph and up or down the numbers […]

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 […]
