This post is probably only for the intersection of the #Venn diagram with circles labelled "#guitar player" and "#electronics hobbyist". I'm not on fora like #diystompboxes and such, so here it will have to be.
Like many others, I've built delay / echo #pedals / circuits using the ubiquitous #PT2399 digital delay IC. They're dirt cheap and simple to use. But the lowest delay period you can use them for is too long for some things, like #flanger / #phaser effects, or even some types of #chorus effects.
But I haven't seen much discussion of alternatives. I've been playing around with one I've built using the #M65831 digital #delay chip. It's not quite as cheap as the PT2399, but you don't have to look very hard to be able to get them for a couple of bucks (Canadian). But it seems to be so much better in this application.
First, it's designed and documented so that you can use a crystal to set its clock OR drive it directly with a CMOS-type square wave. No fiddling with drain currents and on-reset latchup problems.
Secondly, it sounds (to my ear) far better than the PT2399. The #datasheets I have for the PT2399 don't state a sampling rate; the M65831 uses 500 ksamples/s for lower delay times.
Thirdly, the range of delay available is larger. The shortest documented for PT2399 is ~31ms. For the M65831, it's 12.3ms using the default clock of 2 MHz. But the one sample I've tried is happy to run at 6 #MHz, for a delay of ~4ms. That's short enough for #flanging!
As we all look across a sea of lifeless, nearly identically-styled consumer goods, a few of us have become nostalgic for a time when products like stereo equipment, phones, appliances, homes, cars, and furniture didn’t all look indistinguishable. Computers suffered a similar fate, with nearly everything designed to be flat and minimalist with very little character. To be sure there are plenty of retro computing projects to recapture nostalgia, but to get useful, modern hardware in a fun, retro-themed case check out this desktop build from [Mar] that hides a few unique extras.
The PC itself is a modern build with an up-to-date operating system, but hidden in a 386-era case with early-90s styling. The real gem of this build though is the floppy disk drive, which looks unaltered on the surface. But its core functionality has been removed and in its place an Arduino sits, looking for NFC devices. The floppy disks similarly had NFC tags installed so that when they interact with the Arduino,it can send a command to the computer to launch a corresponding game. To the user it looks as though the game loads from a floppy disk, much like it would have in the 90s albeit with much more speed and much less noise.

Inside microchips are nanometer-sized transistors and wires, but how are these nanoscopic structures built? Well, in this video, we’ll explore the EUV Photolithography System built by ASML. This 150-million-dollar machine is essentially a microchip photocopier; it takes the design of a microchip and copies it across hundreds of microchips on a silicon wafer. This EUV Photolithography System is one of the most complex machines ever made, and it encompasses an entire world of science and engineering within it. Specifically in this video, we'll dive deep into the EUV Lithography tool and explore how 13nm EUV light is produced, how the EUV light is focused onto a photomask, how the photomask, or mask, moves around, what the patterns on the mask look like, the projection optics, and how the wafer moves around and the wafer stage. So join us on this adventure into the world of EUV Photolithography!

I was thinking today that I have been responsible for more than just myself my whole life. As a kid my mother expected me to watch out for my younger sister who was born with Down syndrome. I was a teen mom. After my kids were grown there was a husband and grandkids to help raise. Now I am caregiver to my husband and dog mom to Summer. I don't know any other way. Today when Summer sat down and wouldn't stand up I felt really helpless. She is too heavy for me to carry comfortably for her. She can't talk to tell me what's wrong. She just looks at me like I will know what to do. I did my best and although it took awhile and a trip to the vet she feels better. This evening while we watched a spectacular sunset get better and better I held her close and said I was sorry she had a rotten difficult day. She snuggled up like not feeling good is just old news. #Sunset

Sometimes, without expecting it, you stumble across a link to something you were not at all prepared for. Something beautiful.
Old Woman Reading, Gerard Dou, c. 1631 - c. 1632 The book is rendered in such detail that it is easy to see what the woman is reading: the beginning of chapter 19 of the Gospel of Luke. The passage states that those who wish to do good must give away half of all they own to the poor. The old woman’s expensive clothing contrasts sharply with this message: she is still attached to worldly possessions.
