Can I build a SPRING SMASHER for under $150?? 

There’s no programming! Literally just hit some buttons on that chip. You can do it

@@AKracecars Awesome man, I had it on the screen when I was rolling home. I will get more in depth on your video and notes and hopefully have one built by next season. Thanks man!

Yep would be super easy. Lead screw, lead nut, heims, same load cell, same HX711 chip, and a short piece of tubing 👍🏻

With a full Wheatstone bridge, (which an S type is) variance in input voltage shouldn’t effect the reading, as it will effect all 4 legs of the bridge equally. I’ve been impressed with the accuracy of this cell after thoroughly testing it, and is well within our very wide tolerance range (+/- 10lbs). I’m sure what you work with requires much higher accuracy and thus, accommodations must be made!

@@AKracecarsI’m sure we could figure out a way to verify it with one of our calibrated load if you’re interested in that! I’d love to see how well it does

Give your girl my sincerest apologies for me (but keep watching)

@AKracecars 💯! 🤣 Dude, I was literally done with Racing, I sold and literally gave away most of my racing stuff... and then I watched the Carolina Clash (for the 83rd time)... AND THEN you came out with the video of your banned chassis... well, wouldn't you know it? That was the ticket that convinced me to build another chassis... smh. The book that you recommended, "Tune to Win" by Carroll Smith... is badass! Thank You. You keep making the videos and I'll keep watching.

@@RichFifethese comments keep me going more than you know. Keep it up 💪🏻

I wish it was that simple.. without getting too in the weeds, imagine you have a shock with an infinite amount of compression valving.. according to your equation for wheel load, that setup would have less weight on the tire than one with no compression. Jacking force, anti dive, anti squat, LLTD, etc all contribute to wheel load. I didn’t do a good job explaining, let me know if that makes sense or not 👍🏻

@@AKracecars Thanks for the response! After I left this comment, I did a little research on what elastic/inelastic weight transfer was (never heard these terms before). I realize now that the resources I have been reading hold a somewhat incomplete view of how wheel load should be measured. Now that you mention it, of course jacking forces and anti-dive/squat would affect wheel load. My resources treat these effects as if affecting chassis roll/dive/squat was all they did. I'm not completely sure I understand your analogy, though. If we are comparing a shock with effectively no resistance to compression (as if there wasn't even a shock there) to a shock with infinite resistance to compression (as if it were a solid link), then yes, my understanding is that the 2nd shock's tire would experience most of the load at mid-turn, while the 1st shock's tire would experience a much smaller amount of load. Am I misunderstanding what you said? Or, are you saying that jacking force + anti-dive/squat account for more wheel load than is accounted for through the spring + shock assembly?

Yes you got it. I used that example because if you were only looking at coilover linear position and spring rate, you’d be leaving out the wheel load contributions from shock valving too. Infinite compression (solid rod) was just an illogical extreme to try to explain that you could have a totally different wheel rate, without changing the linear position or the spring rate

@@AKracecars I see, that makes sense. Can you recommend any good resources for learning more about this subject? I'm looking to expand my setup knowledge before I start racing next year. Also, merry Christmas!

Bro.. watch my other video about how not expensive both of those are. You could buy a 3D printer, plasma table, and build a smasher for less than it would be to buy a new spring smasher

Trusty ole solidworks. I’ll look into the rp2040. On my next one I was planning on using an arduino, OLED screen, and string pot. We will see how adventurous ChatGPT is feeling on code for the graphing 🤣

There’s a video called: “HX711 Weight Scale Display how to calibrate and how to use ENGLISH” that does a good job explaining

Yeah Bambu P1S is on the short list. They are nasty.

I got the Creality K1 Max and it’s a BAMF too.

The unit of measurement doesn’t matter because you are setting the scale. You could zero it, then put 10 chicken eggs on it, set that point to “10” and it would read in Eggs. Lol

Makes sense now but didn’t at first lol.😂so can I make a load stick that reads chicken eggs as a scale nobody will ever know my numbers!!!

@@NorthernFabandMachineLLC precisely. I hear the magic RF load number is 865 eggs at 400 millimeters

Google sheets 👍🏻

Not yet, Tony is pretty funny. Will take that as a compliment

@AKracecars love the content man.

Forgot to add the dimes to the budget total.. might have pushed it over 150$
