  1. And there we have it! Pins connected to a #BusPirate, #openocd, and contact! Direct memory access. 👌 bootloader from the capsure dumped.

  2. What a big week! PCBs will be done soon. I'm used to quick turn prototype boards that take 1-3 days, but volume production usually takes at least a week. We paid extra for "emergency" service so they'll be done sooner. Parts went to PCBA by courier, assembly will start in a few days.

  3. Let’s talk about injection molding. We got six quotes. One boss took the time to review the Bus Pirate and send photos of plastic materials/styles he thought would work well, at a reasonable price. It was a great start.

  4. KF141 quick connect adapters were assembled by a new supplier. The through-hole soldering looks great, but the boards were covered in flux.

    We sent them back for cleaning. It seems the custom silkscreen survived mostly unscathed.

    FCC and CE testing certificates arrived. We...

  5. First day's case re-production arrived and it looks much better than the last batch.

    The base is flat. The insert nuts are clean. The aux header retaining pegs aren't missing, and the lip isn't deformed. They really slowed down and did proper quality control.

    Manufacturing..

  6. Silkscreen uncle just finished adding the Bus Pirate 5 pinout labels to KF141 quick connectors. We chose the highest quality connector we could source and had the pin labels printed in bright orange to match the release levers. Things were backed up a bit, but the result is nice...

  7. Clear back in September (!), when the Bus Pirate enclosure tooling started, there was a flash card slot. Recently we swapped it for a NAND flash for speed. However, now we have a unused slot in several thousand enclosures. This plug, made in OpenSCAD, fills the hole. Eventually..

  8. REV10 boards arrived. New buffer works, but the cheap Schottky diodes from my favo comp manuf are LEAKY. Bought the Diodes INC version. Installed one but the problem disappeared. Why? Cold morning. Roasted on the radiator a bit to enhance the leakiness. The genuine part on io6/7

  9. Injection molded Bus Pirate cases were manufactured this week.

    We used a super cheap factory with no frills service and the experience has been painful. They're more than a month late and decided to skip the final color test. We just get what we get, but at least it's done..

  10. NAND flash is up and running. Access from the terminal was a breeze, but there was some unpleasantness getting the USB MSC disk working. Spent a day debugging spin locks based on the debugger output, but turned out to be a simple buffer overflow due to NAND block size. Tomorrow..

  11. 1Gbit NAND flash test board.

    The SD card was limiting the maximum speed of the internal SPI bus shared with the LCD. I've already dead bugged a chip and tested it at low speed hanging off the Bus Pirate IO header. It works like a charm for both internal storage and as a USB disk...

  12. Sample AUX cable with dyed crimp housings just arrived. Very pleased!

    Black housings are common, but the dyed-black version reflects light like the other dyed parts and seems to match a bit better. AUX doesn't have a power pin, so we didn't do red at first, but after seeing the..

  13. Is your Bus Pirate 5 genuine? Just perform a GCMS analysis of the sticker to find out! :thinkerguns:

    Most Bus Pirates have a scratch and sniff sticker!

    Rub the sticker and it should invoke themes of soldering (well, ozone) and freshly painted factory floors in that very specific green color. The sticker people have a list of scents (coffee, cherry, etc), but we wanted custom!

    After a scent workshop...

  14. SI7021/SHT21/HDC1080 are nearly identical inexpensive I2C temperature and humidity sensors. Macro (2) in I2C mode demonstrates how to access it with the Bus Pirate, and reads out the key data. I'm still experimenting a bit how best to include device demos - both built into...

  15. Bus Pirate 5 firmware v0.1.0 is here! The new command interface works more like a typical PC command line. Bus syntax (talking to chips) uses a three step compile-run-report process for extremely tight and precise timing. Next week I'll go through my big-ole-bag of breakout...

  16. Jiangsu, evidently!

    We did a deep dive on the cheap test hook/probe ecosystem. There are more and better quality probes than ever before. We're still searching for the origin of the cheap "Shennie" hooks that have been around forever.
