Final batch of #GlasgowInterfaceExplorer Aluminum Cases shipped to Mouser today. Now we have to only continue producing and shipping Glasgows to wrap things up. :)
> btw i've installed glasgow like a couple dozen times now, on linux mac and windows, and as long as the install instructions are followed it works every time
Continuing #GlasgowInterfaceExplorer production. Ramping up batch sizes. Lot's of through hole soldering awaits. Two more batches like this so we should be able to finish fulfilling the campaign! 🤞
did you know: maximum-sized USB HS BULK packets where the payload is all-ones are about 16% longer to transmit than the ones where the payload is all-zeroes or random?
this is easily measurable using the #GlasgowInterfaceExplorer with a slightly modified benchmark applet:
if you don't have a PHY devboard (they are somewhat hard to acquire) you can just get an old router from your ewaste bin or something, cut 12 traces, and cordyceps it with the Glasgow. there's many products with RGMII
looks like i have successfully turned #GlasgowInterfaceExplorer (as well as an RTL8211FD devboard I got from Aliexpress) into a fairly decent network interface card :D
this applet is written idiomatically and with no modification of the core USB framework (using the abstractions every other applet is using, rather than direct access to libusb or something), in a single-threaded CPython 3.12 asyncio event loop
Picked up my #GlasgowInterfaceExplorer that was delivered while I was on vacation. Now once the chores are done I can probably go back and play with electronics between going through pictures!
#GlasgowInterfaceExplorer arrived. It'll have to wait til after work and then I will pretend I know how to use it. I'm hoping to be able to use it to learn USB and write Linux drivers, eventually.
When you get your Glasgow - Digital Interface Explorer let us know! And if you use it, share what you are using it for! Really eager to see them in the wild. :) (A bunch shipped from Mouser yesterday and today, still a bunch more to ship from the most recent batch) #GlasgowInterfaceExplorer
Pretty good progress today. Managed to assemble 50 panels (200 boards) Bottom sides so far. It is the simpler side but I am glad the new stencil seems to prevent a short I was seeing regularly form between two specific capacitors previously. Will save me a bunch of rework time! #electronics#opensource#fpga#GlasgowInterfaceExplorer#manufacturing#smd
Continuing progress on the second general batch. Assembled a bunch of top sides, soldered in connectors and tested them. Putting on serial number stickers is the last thing before packing. We now have 120 Glasgows ready for the next batch. #electronics#opensource#fpga#GlasgowInterfaceExplorer#manufacturing#smd
Next step are the through hole connectiors. We don’t have a wave or selective soldering machine yet. Tub of molten solder seems a bit daunting to setup well. We went for a jig and good old soldering iron instead. It takes currently about 5 minutes to solder one Glasgow including all he connector handling. That is about 4x of the PnP assembly time. But I feel that is the best we can do for now. #GlasgowInterfaceExplorer#electronics#manufacturing#opensource#fpga#3dprinting
And here we go! Now we have fully assembled Glasgow boards. “Only” a few steps remain:
• factory flashing
• testing
• serializing
• packing
remains. (I am under playing it. These steps make up a significant chunk of time to do. We have some help to do it but it should not be under estimated. I will post more details about it in due time) #GlasgowInterfaceExplorer#electronics#manufacturing#opensource#fpga#3dprinting
