👨‍💻 I am interested in wired & radio communication, DSP, (embedded) software dev & engineering, FOSS, reverse engineering, IT security, space, programmable and non-programmable bricks, old and new computer technology, robots, machine embroidery & other things. Living in 🇩🇪. Speaking 🇩🇪/🇬🇧/💻 and understanding a little bit of 🇫🇷.
Today I did some welding and got ends on the large pins (washer welded to one end of the pin). The bucket is now fully locked in. I need to install cotter pins in all the pins now.
@RueNahcMohr @MLE_online and it even has a TÜV label already. 😀

How well do you know JavaScript's Date class?

@hennichodernich Nice, I didn't expect it to run OpenWRT. But I didn't really keep track of that project tbh. Planning to use the small thingie for my "Internet of Shit".
@funkylab And therefore I wasn't going to open it anyways. Just in case I'd plan to do the soldering.
@funkylab well, there will quite likely be some sort of dumb (probably multi-port) USB 5.0V power supply anyway. I'd only hot glue a USB cable to the socket of the device and not the whole housing itself, which will keep the AP modular and movable.
This is the thingie!
Wobbly micro USB connector supplying power to this tiny WiFi access point. It's a slack joint. Photo in the next toot.  🧵
Hot glue to the rescue!

Open it and re-solder!

@tjw On the day Opteron was supposed to tape out, a colleague discovered a logic bug. After some analysis, we figured out we could fix it by disconnecting a wire from one gate and attaching it to another. But running through or design flow would take days, and the ripple effect of changing connectivity could cause more problems. So I loaded the chip mask into VIM and modified the polygons directly, then we taped it out.

Don’t remember for sure, but I don’t think we told management 🙂

@GuyBirkin Nice photograph! "Crown shyness" came into my mind: https://en.m.wikipedia.org/wiki/Crown_shyness

@f4grx of course

@whitequark startpage gave this with the 1001-011 search request https://geo-matching.com/products/high-performance-tactical-grade-mems-gyroscope

(I considered the second line a date code and the third line a lot code)

@f4grx huh, what was the query?

also, wtf is that website? ubo lite doesn't let me follow any links that lead to "syndicatedsearch.goog"

@whitequark ah here is the query I made previously.

@whitequark Also, what about this little dude? if the golden ones are 1 axis acceleros (so there are 3) then this little one should be the 3-axis gyro.

@hennichodernich @whitequark what a surprise!

(the gyro random walk figures far below one degree per sqrt hour are highly optimistic given the bias instability figures, imho)

@whitequark this page has links to other similar looking products giving reference XDR2067 , including a link to this PDF which I cant read, see page 6
