Chaining 4 74HC595 shift registers together

I have a question about chaining 4 shift registers together.I am going to be sending data to four shift registers and my question is this, when all four are loaded and latched if I send more data is it possible to only send data to the first register in the chain without the others losing their values?

Find or How to Replace Old Dried Out Gaskets in a Set of 4 Ceramic Kitchen Canisters

We have a set of 4 ceramic kitchen canisters that are so old the foam seals, or gaskets, have dried out. I cannot find replacement gaskets anywhere. They were made by an individual, so there is no company to write to for replacement parts. Does anyone know who sells such gaskets? Foam or rubber or silicon will work.Or, is there a way of making replacements? I've seen amazing things done on "instructables" with silicon; molds, fake heads, toy octopus, etc. But I have never worked with it. Is it OK for a seal that will be in close proximity with salt, sugar, flour?The canisters are glazed ceramics that some individual has made.Attached are photos of the canister, mating surfaces, and existing gasket.Any suggestions will be appreciated.Thank you.Phil Brown, Southwest Wisconsin

Need help building a small extension for my desk

I got a microphone arm that clamps down to my desk ( can be seen in the picture) but the problem is that it's right in front of my mouse. I have to have it folded it up because it does not have to be extended since it's right there. It has gotten annoying after a while and I change it to hang from essentially where my window is ( also shown). my desk is has drawers and doesn't have any edges to clamp it down to so I was thinking if I can make a short extension for it. I don't need a whole new section I just need a secure extension that can be used to sustain the weight of the arm and mic. I tried drawing it and I hope it helps showing you guys what I envision. Thanks!

Removing Broken M2 Tap from Anodised Aluminium 2014.

Hello Everyone,As you might have read, I have a Milled Aluminium 2014 Block which is Anodized with Black color, Today when I was tapping the holes of it, the M2 Tap broke and got stuck inside that hole, there is no portion of it outside the hole, so I can't unscrew it and pull it out.I saw a few videos on youtube on how to use alum water, or electrolysis(with 10% dil H2SO4) to dissolve or chemically remove the Tap bit from the hole, But my question is is it possible that using any of the above options could destroy the anodizing on the job work. and is there any other easy method I can use?Please Note that the tap bit is M2 and There are no tap extraction tools for a bit that small on the internet (or Locally Available in India) but if you find one Please post links for the same. Please Be Positive and make this community a happy place. Thanks.

Creating an electromagnet as powerful as an NeFeB magnet with same size

Is this possible?So I'm working on this project on levitation using superconductor and strong NeFeB magnets. I'm try to determine the possibility of replacing the magnets with electromagnets equally as powerful and of the same size if not smaller. But I'm bit skeptic about the idea as I'm not sure how possible it will be to construct such electromagnet (or buy them preferable). Is this something that is possible? can anyone reading this give me recommendations? thanks

Trying to create my own car head unit.. Sorta.

So i enjoy electronics, so i thought of an idea that would really benefit my life. I enjoy listening to music in the car. Like really enjoy it. Currently i have the original head unit that came with the ford focus mk1. Its terrible, and the speakers distort at loud volumes. Plus there is no way currently for me to listen to my own music apart from a CD. Which come on.. no one uses anymore.So here's my idea that im finding difficult to bring to light. I was hoping i could create some sort of botch head unit. But i want to create this using components that are not end products. So no i do not want a £100+ amp that does this for me without the DIY. It should be a lot cheaper to do this DIY.So my idea was 1 amplifier circuit board, which is difficult to find to power 4, 4 Ohm speakers. So my idea was to have 4 separate amplifiers for each speaker. I can't find a single channel amplifier to power a 4 Ohm speaker however. The signal the amplifiers would receive would be through an auxiliary cable or bluetooth reciever.Any ideas to point me in the right direction would be awesome. If there's a loophole in my idea then please let me know. Still a lot to learn, but that's what were here for right.Thanks in advance.

Time constants of batteries ?

Hi,I'm trying to figure out the way solar battery charger work and I'm a bit confused about the following point.I read that for batteries you could consider the PWM voltage to be equivalent to DC. This I understand well for average voltage (obviously it's the same), but what about the dynamics ?If your PWM frequency is something like 100 kHz, that's a 10 µs period. Does the battery has time to follow and make big voltage and current peaks or does it just averages all that to more decent values ?One way to put it is : Are the battery time constants indeed much bigger than the PWM period ?Thanks for any idea on that topic !

Rescue a defunct phone charger

I have an old cell phone charger that is very handy for charging my Kindle Touch and a set of Bluetooth earbuds. It quit working one day after someone used it to charge a high demand device. I read that the capacitors in these often fail. I got two electrolytic capacitors at a surplus store for less than a dollar total. I had to use a fine saw to open the plastic case. The new capacitors were the same electrical size, but not the same physical size. Closing the plastic case was not an option. I covered all exposed electrical contacts with hot glue, which is an excellent insulator. It looks ugly, but I have a good versatile charger again. (The high voltage connections are buried deep down where my fingers can not reach. As best I can tell, the terminals covered with hot glue for insulation are all low voltage.)

My question is ;1.Why current I1 is following through point A to D in loop ADBA. 2.Why current I2 is following through point D to C in loop DCBD.My confusion is that why current are following through these two paths. As current always flow through level of a higher potential to a level of lower potential but here it seems opposite.

I need help writing a program on Lego Mindstorms EV3

Whattup y'all, I have a Lego Mindstorms project underway, but I can't figure out how to write the program. If somebody out there who is familiar with programming EV3 could help or give me some tips, that would be great!The project is as follows: I built a start/stop timer for micro drones (i.e., a Tiny Whoop) so you can measure your time around your course. Start the program by pressing the center button on the Smart Brick. The setup measures whether or not the drone is on the starting block with the color sensor (either ambient or reflected light intensity). After the drone leaves the starting block, a timer will be set. The timer stops after the drone hits the stop gate, which presses the touch sensor. The time is then displayed on the screen, where you can view it, and then the program is restarted by pressing the center button again.My problem is that I have no earthly idea of how to make a timer with the EV3 software. If you know how, then screenshot it and send it to me, and you will be rewarded with a great Instructable in the near future!Auf Wedersehen, and thanks in advance!

Wood varnish questions

I want to varnish this birch plywood platform to keep it as waterproof and UV resistant as possible but also keep it as close to it's original pale birch colour as possible. i've never varnished anything before so i've been googling for answers and i'm getting some conflicting information, i've been looking at different clear outdoor varnishes and most claim to protect against UV light and not leave a yellow tint but most reviews say otherwise and some general varnishing info articles claim that clear varnish can't protect against UV at all and i'd need a dark stain which i really don't want. so what can i do to protect the wood against the elements and maintain the colour as much as possible? can i combine varnish with other stuff? i found some clear 'marine varnish' is this heavier duty than normal wood varnish or something?is there an alternative to varnish that will have a similar effect?if i need to modify the platform later, cutting bits out or drilling new holes is it ok to just apply another layer of varnish to reseal it or will it need preparing in some way or some additional step?

Laser Engraving Under Glass.

Just put a video on Youtube about Laser Engraving under glass.A lot of people have made their own Laser Engravers using one method or another.I did the same using old DVD drive mechanism's a couple of Easydrivers an Arduino UNO and a 2 Watt Laser Diode and a Constant Current Laser Driver with TTL / PWM.Arduino has GRBL 1.1f loaded on to it and I use LaserGRBL (free program) to do the image settings, generate the GCode and burn the image.It's a good little machine, although the workpiece size is only 39mm x 39mm max.Eventually I'll build a bigger machine, but for now it does what I want it to do.Recently I removed the fan that blows the smoke away because it was whining a bit and getting on my nerves.So instead I tried using a piece of glass cut from an old flatbed scanner, on top of the workpiece.Seems to be good quality clear glass, I suppose it had to be if it was in a scanner.This stops the Laser from producing smoke and also soot.It does however produce a sticky residue on the back of the glass, but that can be cleaned off in soapy water.I was quite surprised at the results.Laser Engraving Under Glass.
