How does your signaling work? Also what framework did you use to build your host side application? How much time are you expecting between messages? In general the kinds of debugging techniques I use when solving problems like this are doing things like: opening the serial port in PuTTY or other similar tool to see the data as it comes in. (If your data is not ascii format it can be useful to make a simple command line tool that prints the received data in hexadecimal or whatever is convenient). Another good one is testing the host side application independently. You can get a usb to UART module and put a jumper across the RX and TX pins to create a loop back device. Then you modify the host application to send the data it is expecting to receive from the microcontroller and proceed to debug

Back when I had the luxury of living somewhere where I could have a forge I spent most of my time learning to work metal and wasted no time worrying about semantics or whether my equipment looked cool to other people. Now I live in the city and have no forge, so I’ve settled for reminiscing about the good old days as I respond to silly UA-cam comments. Good luck on your project though, blacksmithing is a very cool and rewarding hobby. Keeps you active too unlike a lot of pastimes

Bro you are stupid, bellows in Africa are EXACTLY how it was shown in the video. They power iron smelts with such bellows : they make theirs with a leather hide covering a hole or a jar, with a hole at the bottom. Your design is very good Andrew, and some people are retarded while thinking they know better than anyone else. Primitive bellows from the copper age were just a leather bag, and some had very weird shapes. Because it doesnt look like an european design doesn't mean it's not a real bellow. For some applications it was advised in the 1700s in France to use A HAND FAN. Looking good isn't what matters in a craft, it's making something effective.

I wanted there to be enough clearance that it would be easy to engage all the way once the teeth lined up. So based on the relative speeds of rotation, and how fast I thought the driver could shift the lever. But honestly that isn’t a great approach since neither of those quantities are known with any degree of certainty. If I were to redesign it I’d make it have a lot more teeth, so that the teeth mesh up more frequently, and then add as much clearance as possible while maintaining a comfortable level of strength

I think it was 4130 steel. Thanks, glad it helped!

Good idea, I have one of those I will try it with if I get the chance. I'm guessing you are probably right that the 16u2 is setting the packet size. I tried to see if I could figure it out from the arduino-usbserial firmware on github, but it wasn't immediately apparent to me. But maybe you will have more luck with it.

@@andrewphillip8432 maybe also see if it varies with baud rate - both using the 16u2 and an FTDI...

Interesting idea, I have not heard of anyone trying such a thing before. My guess is that the reason it is not successful is because the Due is configured as a USB device, and to establish a connection it needs to be connected to a USB host such as a PC. If you can find a way to configure the Due as a USB host then your idea might be possible. If your goal is to share data between two Arduino’s, then I would suggest using SPI or I2C instead of USB

@@andrewphillip8432 DUE is using 3.3V TTL and UNO is using 5V TTL. I am not sure to connect the boards through the pins

I think that would probably work. It might require faster pumping to output enough air

Not sure. I’ve only done this to scrap the tank, not for replacing the valve and continued service.

Me too man I remember being pretty down about giving up on that engine

Sorry bro didn't mean to give ye a headache

Thanks for the support I appreciate it!

Ha so my video is a hoax?

@@andrewphillip8432 maybe i tried a few ways and yours does not make sense, i had to cut a metal bar and bolt it down to my sheds floor and make a special bit from a 2 inch steal pipe and put a lot of torque to open it, about 250 - 300 pounds

Hi Patric, thanks for the comment. I’d probably use a short lever and an aircraft style push pull cable to control the clutch in most cases. I’m thinking the lever would pivot on your vehicle frame, and would have connecter links reaching to the aluminum “yoke” both on the top and bottom (hence the two pins it has). Then the push pull cable can attach to any convenient location on the lever and be routed to the operator controls. It should be simple to add an extension spring somewhere on the lever to make the clutch normally engaged, or normally disengaged, if needed.

A well pump handle is a similar kind of mechanism to what I describe, you can google that if a visual would be helpful

@@andrewphillip8432 Thank you greatly for the advice, will definitely look into them!

You can get the components for cheap on ebay. You’ll need a TL072 op amp (or pretty much any other op amp) and an analog switch (I used a CD4066), and resistors and capacitors. And of course an oscilloscope to view the output

Thanks for your comment, cheers! Andrew

People who used this told me it doesn't shift very well while it is rotating quickly. If that is important for your application, then I would recommend beveling part of the teeth and increasing the tooth spacing, so that it becomes easier for them to come into mesh

@Abraham Morrison yeah I machined everything from scratch, so I’m not sure of the technical names

I designed it based on the formula for stress in a cantilever beam, since each tooth of the dog clutch is much like a short cantilever beam with one fixed support. The book I learned from is Mechanics of Materials by Gere and Timoshenko. I also did an FEA analysis in SolidWorks to verify this design.

@@andrewphillip8432 thank you sir. Really appreciate it

@@muh.alfinmasykurmuharram6864 glad I could help

I designed it for 400 ft lbs if I remember right. I chose three teeth because it guarantees even load sharing. Kind of like how a three legged chair always sits flat on the floor, whereas a four legged chair might have one leg not touch the floor. This way each tooth is stressed equally

@@andrewphillip8432 thanks

Also what is Outer dia for that clutch

@@smk3399 roughly 2.5”. Also I used alloy steel. Something like 4340

​@@andrewphillip8432three points are the basis of a plane 🤓

also your video came out at a good time. I'm looking into a due mainly because of this video and a big project I'm working on

@@lamboking8able If you are using SerialUSB then only the USB protocol is used by the MCU, and so baud rate will have no effect. It does not affect how many characters go in a packet. If you use the standard Serial functions, then baud rate will have an effect, because the MCU must send the data in standard serial format to the chip that translates the serial data to USB protocol. On most Arduino's this is an atmega 16u2. Since the 16u2 is an MCU just like the atmega328p, a cool thing you can do is to write programs that run directly on it, without using the 328p. This is rarely useful but is an interesting thing to try.

Glad the video was helpful! I could but it would be very expensive since it took an entire week of work to make it

@@andrewphillip8432 How much would it cost since the budget for the project is not too big?

@@niclas3713 if I billed my time at a normal machine shop rate $80/hr. then it would be $3200 plus price of materials. So even if I did it for a fraction of that it would still likely exceed the project budget

@@niclas3713 machining is unfortunately very expensive and time consuming.. which is why I became a machinist since I also could not afford to outsource machined parts

@@andrewphillip8432 Okay thanks but that's beyond the scope. I'm about to build a wakeboard that has a total price of $600 including the motor and that would be completely out of the price range.

Good catch! Now I feel kind of silly for making such a point of pronouncing it the English way. Oh well

@@andrewphillip8432 The worst part about that touch of American/English arrogance is that you immediately lose credibility. I barely know anything about Arduino but I do know it's inventor is Italian. Failing to do even that basic research makes me wonder what other errors-in-fact you may have missed because of your 'focus'.

@@MuckBootMaine fair enough I can’t blame you there. It’s hard to find this type of information though so I just wanted to share it with the people who can look past basic mistakes. It’s kinda a silly thing to be upset about really but obviously a dumb mistake on my part

@@andrewphillip8432 This is great content and really helpful actually. Thank you for sharing. It helped me understanding things I've been searching for hours. Thank you so much!

I know I'm quite randomly asking but does anybody know a good website to stream newly released tv shows online ?

@Elon Misael Try flixzone. You can find it by googling =)

@Elon Misael i use Flixzone. You can find it by googling =)

@Elon Misael Lately I have been using Flixzone. You can find it on google :)
