Ian at DangerousprototypesFirst 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.

Ian at DangerousprototypesSilkscreen 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...<a href="https://mastodon.social/tags/buspirate" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#buspirate</a> <a href="https://mastodon.social/tags/silkscreenprinting" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#silkscreenprinting</a> <a href="https://mastodon.social/tags/opensource" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#opensource</a> <a href="https://mastodon.social/tags/DIYHardware" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#DIYHardware</a>

Ian at DangerousprototypesClear 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..<a href="https://mastodon.social/tags/buspirate" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#buspirate</a> <a href="https://mastodon.social/tags/opensource" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#opensource</a> <a href="https://mastodon.social/tags/electronics" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#electronics</a> <a href="https://mastodon.social/tags/DIYHardware" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#DIYHardware</a>

Ian at DangerousprototypesREV10 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.

Ian at DangerousprototypesNAND 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.

Ian at Dangerousprototypes1Gbit 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...<a href="https://mastodon.social/tags/buspirate" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#buspirate</a> <a href="https://mastodon.social/tags/electronics" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#electronics</a> <a href="https://mastodon.social/tags/opensource" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#opensource</a> <a href="https://mastodon.social/tags/DIYHardware" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#DIYHardware</a>

Ian at DangerousprototypesDo you have a favorite quick connector? I made a small PCB to use KF141 connectors with Bus Pirate 5. KF141 comes as single terminals that stack together with 2.54mm pitch between terminals. It comes in vertical and right angle versions. Very handy for quick bare wire hookups.<a href="https://mastodon.social/tags/opensource" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#opensource</a> <a href="https://mastodon.social/tags/electronics" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#electronics</a> <a href="https://mastodon.social/tags/DIYHardware" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#DIYHardware</a>

Ian at DangerousprototypesSample 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..<a href="https://mastodon.social/tags/buspirate" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#buspirate</a> <a href="https://mastodon.social/tags/cables" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#cables</a> <a href="https://mastodon.social/tags/custom" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#custom</a> <a href="https://mastodon.social/tags/DIYHardware" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#DIYHardware</a>

Ian at DangerousprototypesSI7021/SHT21/HDC1080 are nearly identical inexpensive I2C temperature and humidity sensors.

Ian at DangerousprototypesBus 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.

Ian at Dangerousprototypes:toot: Bus Pirate 5s and the production tailings.

Ian at DangerousprototypesJiangsu, 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.<a href="https://mastodon.social/tags/testhooks" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#testhooks</a> <a href="https://mastodon.social/tags/testprobe" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#testprobe</a> <a href="https://mastodon.social/tags/buspirate" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#buspirate</a> <a href="https://mastodon.social/tags/DIYHardware" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#DIYHardware</a> <a href="https://mastodon.social/tags/opensourcehardware" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#opensourcehardware</a> <a href="https://mastodon.social/tags/electronics" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#electronics</a>

Ian at DangerousprototypesThere had to be a better way to connect a probe cable to a breadboard or pin header. Something better than probe hooks precariously clipped to the end of jumper wires...so we hired a pogo pin manufacturer to mill a custom pin.Normal screw and spring turning factories can't handle the specs, but pogo pin manufacturers can. Keen observers will note that the photo doesn't match the diagram.
