anthon Posted May 12, 2017 Author Report Share Posted May 12, 2017 So, a few things have happened since my last update. The good news is that my bootloader is basically working. There are a couple little tweaks left to implement. But it does its job of updating the board firmware. I was being clumsy with my bench power supply and accidentally released the magic smoke. So I had to assemble a new board. During testing the new board, I found that the integrated usb hub works, but if I connect another downstream hub, it fails. At this point I don't remember if I ever tested that on my original assembled board. I did test it on the development kit board, and it worked. So I don't know if it's a problem in my board design or a defect on this board. The pcb has a slight pressure mark on one of the usb traces. Otherwise, I can't find any defect. If that were the problem, I don't think the onboard hub controller would work either. The one empty pcb I have left has a pressure mark in the same spot. So to make eliminate that possibility I would have to order more pcbs. And they would probably have the same issue. It could be the hub controller I'm using. To test that idea I would have to redesign the board for a different controller. Ugh. Quote Link to post Share on other sites
CelGen Posted May 19, 2017 Report Share Posted May 19, 2017 So what is your price going to be now that BMOW is selling a competing (and overly ugly) product at $50 USD? Quote Link to post Share on other sites
anthon Posted November 7, 2017 Author Report Share Posted November 7, 2017 A related topic came up in IRC today so I figured I should really post an update. I solved the unreliable behavior with daisy-chained hubs. Some USB devices draw a lot more inrush current than others. Adding a capacitor to each port solves this problem. I redesigned the PCB to be about 40% smaller, switched to an RGB status LED, upgraded the ESD protection diodes, and probably a couple other things I have forgotten about. I haven't ordered this new board yet. I want to review the layout again first. When I will get around to doing that, I don't know. Quote Link to post Share on other sites
68krazy Posted November 8, 2017 Report Share Posted November 8, 2017 Did someone say R G B ?! Sounds like this is going to be a very refined product when it's done. Looking good so far! Quote Link to post Share on other sites
Trash80toHP_Mini Posted November 8, 2017 Report Share Posted November 8, 2017 I've had KVM switches and conversions on the brain for a bit now. Wondered if there might be a better spot than the DIN port to hook something like this into a TTL switchbox setup? Quote Link to post Share on other sites

timmerk Posted December 25, 2017 Report Share Posted December 25, 2017 Will this be basically the same thing as the ADB-USB Wombat (https://www.bigmessowires.com/usb-wombat/) ? Quote Link to post Share on other sites
anthon Posted December 25, 2017 Author Report Share Posted December 25, 2017 It's almost the same as USB Wombat. The primary differences are : * ADB Busboy has 2 USB ports * ADB Busboy only allows you use USB peripherals on ADB computers, not the opposite. * ADB Busboy has better power protection between the ADB host (computer) and USB bus.

mietek Posted March 21, 2019 Report Share Posted March 21, 2019 What happened to ADB Busboy? Will you release the sources? Quote Link to post Share on other sites
anthon Posted March 21, 2019 Author Report Share Posted March 21, 2019 I have pivoted the project in a different direction. Keeping quiet about it until it's ready, because knowing me, it could be a while. Quote Link to post Share on other sites
