Open Logic Sniffer preorder update

March 27, 2010 in logic analyzer, preorder by Ian | 7 comments

This is the manufacturing prototype of the Open Logic Sniffer logic analyzer. Parts are all in-house at Seeed Studio. Procurement is usually the most hazardous and delay-fraught phase of a preorder.

Assembly, which will begin by Monday, is usually pretty quick. After assembly, the boards will be inspected, programmed, tested, and shipped to preorder participants. Read more about the process in the preorder overview and FAQ.

You can reserve an Open Logic Sniffer for $45, including worldwide shipping.

    Is it worth ordering one or will there be revisions coming in the near future that I should wait for? I don’t want to follow the Bus Pirate scene where there were like 4 revisions…

      There will be always something better tomorrow, next week, next month or next year. So you’ll need to see for yourself if it meets in its current state your expectation adn if you willing to spend the asked price for that. I personally think it is a bargain especially for hobby-use, for example the saleae cost 150$ at sparkfun, has just 8 chans and a 24Mhz sampling. Ok it comes in a nice casing, has probes and a printed manual. For about 100$ you should be able to make a great probekit. The OLS is also opensource and you are free to enhance it to meet your goal(s).

      BTW the last two or three revisions of the buspirate are more or less the same HW platform. The differences as I know of are in the pullupresistors (v2 has only two and v3+ 4) and a different layout of the connector (it still has the same pins but on different positions)

        Hey Colin,

        There will be revisions in the future, not immediately, but there are bound to be as we learn new things and improve the hardware after working with it and manufacturing it for a while. I think the open source hardware scene will always have a lot of revisions because an open design gets so much feedback (and we can’t hide our defects under a patent, copyright, trade secrets, etc).

        Just to follow up on the Bus Pirate and what Sjaak said – there are 5 versions and revisions of the Bus Pirate, and more are certainly on the way. Bus Pirate v2go and v3 both had 4 pull-ups. V0a had 2, and v1 had 4 (manually set with jumpers), but neither were sold to anyone (not by me anyways). v2go was the first to be sold, v3(a) followed but it was only a manufacturing update based on my experience running the v2go fundraiser for Hack a Day, I redesigned the PCB to make it easier, faster, and cheaper for Seeed to manufacture (mostly to address supply issues). There will be additional revisions that make it easier to perform an automated manufacturing self-test, and we’d like to move to an SMD header in the future so the boards only have to go to pick&place and reflow, and not the additional trip to a hand assembler or wave soldering plant to have the headers added. Regardless of version or revision, all Bus Pirates since v2go run the same firmware and have the same features, with the v4 bootloader upgrade they also run the same bootloader.

        Sorry to anyone who has written me in the last few days – I’ve been moving and I just got the internet going. All email from the last 36hours will be answered tomorrow :)

        Cheers,

        Ian

    What about the probe kit? I ordered some colorful ribbon cables to make my own connectors and will order some jumper wires with OLS but I don’t want to give an order just for the probe kits.

    So Ian, what you’re saying is that it wouldn’t be a huge issue to just order one now. Even if there were upgrades they probably wouldn’t be significant enough to affect operation that much?

    Meaning that this (v1) will still be constantly supported in the future?
