Hmmmm, crazy new idea for flattening response of the AKL-PT5.
Right now, I see slow peaking up to around 5-6 dB at 18 GHz, probably caused in large part by parasitic capacitance of the tip resistor.
Adding L to the signal path seems like a bad idea since it won't be co-located with the resistor (and thus there might be reflections between them).
But what about adding L to the ground path? Some preliminary circuit theory simulations (not full EM models) suggest that low single digit nH down to maybe a few hundred pH of extra L in that path (on top of the estimated 6 nH for the lead wire) could improve things a fair bit.
I just went to check a dimension on some screws that I plan to use on a current project, and when I went to view the product detail to see the drawing with dimensions, it told me I needed to be logged in to view product details.
Since when? Can anyone else confirm this?
If true, what a shitty move that erases a couple decades of good will with engineers everywhere.
@jaseg you seem to know about things, or may know someone who knows: Is there a (ideally free) gerber viewer that can display net names and/or cross probe with a schematic (e.g. with kicad)?
I'm thinking of a use case where you want to view schematic and gerber data for board debug but don't want to be connected to a license tool or opening a heavy duty program in a remote vm. (E.g. Siemens Xpedition)
Quick question for the #electronics side of Mastodon. What's the proper name for the small plug terminals you get on multimeters and similar equipment? Is it "banana plug socket"?
I found this crate in the alley today… care to guess what was inside?
This is an experiment in publishing for 2023.
Instead of replying to all of the comments about one of my projects on @hackaday I responded on my own damn web site.
Today's exciting mail delivery is Vol. 87 of @makemagazine with my geometric Illuminated tote bag on the cover!
Many years ago I published a lot of photographs under Creative Commons licenses.
And like most people who publish I have a Google Alert set up for my name, so it's always fun to see how people use the photos. (And properly attribute them to me.)
Here's the latest, which is a bowl of ping pong balls.
Shifting gears from switch power supply debugging to logic bugs in hopes of maybe making more progress there.
The symptom I'm investigating is that sometimes, for reasons currently unknown, the switch doesn't forward any packets.
Reloading the same FPGA bitstream several times usually solves it, suggesting it's not a timing bug as I had originally thought. It's likely something to do with resets or links coming up in a bad state.
I managed to get some logic analyzers on the FPGA during the failure condition and determined that frames appear to be leaving the QSGMII MAC intact, but are not being written to the QDR-II+ (the write enable on the memory controller never goes high).
This suggests something is going haywire in the CDC between the MAC clock and the fabric/RAM clock.
Hey, @drdrang . Do you think it’s unreasonable to expect a recent college graduate in mechanical engineering to know how to go about determining the size of a shaft key based on a given shaft size and torque?
One of my neighbors got tired of seeing their unused dish on the roof of their house from the second story deck, so they had a neighbor turn it into a piece of art.
(This is a venting post, please don't tell me to "just learn it" because, I will... when I find some free time.)
I was set to switch from GitHub to Codeberg, but realized there is no graphical client.
I'm a hobbyist, not a full-time software dev, and yes, I use the command line every day, but 95% of my use of GitHub has been using the GUI.
I was hoping for a quick & easy transition, but I'll need to set aside some time to read up on the CLI stuff now before I can start getting things there.
What's that? A Mastodon in Milwaukee!?
I tell ya, this Mastodon thing is really taking off!
