dude that thing can chow get some propper toolholders and a carbide endmill and i bet you can cut that cycle time at least in half but probably even more
Your surface finish problem is due to a number of things: Thin plate, you cant actually clamp hard or it will deform No support under thin plate, you can use another peace of aluminum, wood or plastic so the part is sitting on it Too big of a milling tool, to be able to use that tool the part should not be able to move/wobble/flex in any direction Im pretty sure those arent aluminum milling inserts, you need a very sharp cutting geometry for aluminum otherwise it will have poor finish or even glue to the tool and the surface Like in this part if the surface finish its good next to the jaws but not in the middle your speeds and feeds are alright, is fixturing problem If you want a decent surface finish in the same fixing conditions you can use a smaller endmill to mill the surface, if your cutting forces go down you wont have the same problem
It needs only one word to describe engeneering, handcrafting and designing the Motherf*ckin' Formula 1 in your garage... AMAZING😍 PS: Are there some more skills we dont know about!? Perhaps jet fighter design or Space Shuttle 2 maybe😂
How might somebody go about doing this kind of fabrication work as a career? What kinda of degrees, certifications, or specific skill sets would I need to have?
awe, Wes ... c'mon. Please consider doing another update for us. We loved this topic. and whether "free valve" or something else, you are due for a video, are you not..? :)
After using the washer pump 5 times for the windshield the washer wiper should engage, then after another 5 it should again, if it don't you need to spend your kids co9llege money and fix it
You have to do a collab with SuperMatt; I'm not sure if we will see great engineering or need trauma care! Good to see progress- at this rate we might see it get pushed around the block for Christmas and lap under it's own power before fall next year! Whoopee! If it doesn't work with SuperMatt, look Robert Dunn up- he has a thing for a "different take"!
Me and my dad are building something similar "very similar" to this I have a lot of questions that I can write below this you can answer them if you want : ) thanks by the way the car is going to be all electric so keep that in mind if you do answer my interesting and questionable questions. 1. should I build a canopy thing to protect me and 10,000 dollars worth of electric parts from getting soaked 2. should I use a f1 like steering wheel like you did or use the one you used in the first edition of the car. 3. should I make it street legal at some point ? I promise that I "MIGHT" not run people over Ahahahaha!! 4. Should I race you when its done I don't know how I'd get it to you I live in Ohio and yes Ohio people are normal most of the time. 5. How much did building the body cost how much does it weigh and is it a PASTA-bility that we, we as in me and my dad purchase it because we have none of the tools to build it. 6. that's all I don't actually have more questions. thanks for making these videos and admitting that you aren't exactly the best at any of the important parts of the build like coding that made me a lot less scared I didn't think that I'd be able to do the project you looked very good at everything in the videos besides when you admitted you weren't bye bye :) <- a devious sinister perhaps smile.
Word of (unwanted) advice from someone who actually did use those sorts of electronics for quite a while in uni and still does as a hobby, plus did actually implement this analog read multi switch system you have **once** : -when you actually put the design in a harsh environment, what can happen is that noise from other components, vibrations and other unforseen interactions induce voltages that offset the actual value the circuit should be making. -the analog signal ports measure voltage RELATIVE TO ARDUINO'S GROUND - MAKE SURE IT'S GROUNDED WELL but avoid ground loops. -watch the currents flowing through that analog measuring port (I managed to fry one board that way lmao) and what happens when you push a few buttons at the same time - simple contact switches can momentarily connect due to vibrations and you'll get unintended behavior from the switches (same with switch bounce upon activation and deactivation). Do test it out though, it might be perfectly fine and I'm worrying for no reason. Dig the screen, looks professional! Arduinos have built in pull up resistors which are handy when designing switches and sinal buses. You can also use stuff like MCP23017 or PCF8574 - all they need is a library that already exists, just connect it, import the library and code away. It's handy when your electronic circuits consume too much power, which I'm assuming isn't a problem with a V12 behind your back lol. It **could** be a neater solution with less cables though (on the other hand, I hate the I2C protocol and I always had problems designing devices that would reliably read it without fail if they weren't sitting still like on a desk, and these port expanders are based on it). As for code, simple: simpler is better. The architecture is correct (using arduino to read inputs and send strings/payload to the display). The only difficulty is orchestrating arduino to handle multiple inputs at the same time, which I assume is the case since you have quite a few sensors there. For that, there is a simple trick however, that comes under many different names and ideas, but the one I can relaibly find in google is protothreads. Divide a jobs into tasks, put them in a loop and let it rip. Never use sleep (it messes with hardware interrupts which I assume you're using for rotary encoders) and it will work just fine. The nano is a suprisingly capable piece of hardware and only 1 project I ever did actually required me to use something more powerful. nRF should be plenty fast - up to 2 MegaBytes per second, which is probably enough bandwidth to stream your input data in "real time". You sure it's set up right with max power and speed rates? Does it have it's own power supply (it really doesn't like voltage drops)? Could also be that other operations in the code take too long and before arduino gets to the code for writing/reading, meaning it misses packets? nRF24 also sends data over 2.4GHz ISM band, meaning it competes with WiFi, bluetooth and everything other also using that band - maybe it's just in a noisy environment? Speaking of, I worry if things like the alternator won't induce overwhelming amounts of electromagnetic noise making the radios deaf. Good luck! I always wanted to make one of those open wheelers like you're doing myself, but I don't have tools, time or even a garage, so I really wanna see you succeed!
Impressive! My only comment is that the constant use of hexagonal 'holes' in supports has to be heavier and weaker than simple triangulated truss structures. Oh, and the curved pivot for the suspension, which is loaded in compression, must be weaker than a straight line and wouldn't need the extra support you've engineered mid curve. Remember Colin Chapmans's edicts. "Simplicate and add lightness" and "every fastener needs to serve multiple roles", i.e. fasten more than one item. Do you have an estimate for the finished overall weight?
Haven't checked in on your channel since maybe DIY freevalve, it's great to come back to see you're all shredded and you've got a speed shop logo and you're pushing the production value -- no notes, just kudos and congratulations! All the best to you and your endeavors, fellow FSAE alumni
There is a phrase.. smashing Gnats with sledgehammers. I think the level of overcomplication you employ to everything is at a level that is truly surprising. THat is by no means a insult. I think.. just because you can.. doesn't mean you should is something to think of. THANKFULLY..... you are focusing the chaotic energy for creation and overcomplication on ONE project.. and have "finished" it multiple times now. SO its only getting better. Which is a rolling pile of success. SO yeah. HUGE Congrats on being able to "finish" steps along the way.. make it work.. then redesign. Instead of dropping the project to the woulda shoulda coulda land.
