Can a Hot Wheel Break the Sound Barrier?
This is our second high speed hot wheel launcher and this time we are once again taking the crown of the worlds fastest Hot Wheel Launcher. Be we aren't stopping there...we are trying to exceed the speed of sound with a hot wheel by using a more advanced launcher and some custom 3D printed components.

      @EngineeringAfterHours Před 2 měsíci

      What failure mode from these videos do you think gussets have prevented?

    • @superbmediacontentcreator
      @superbmediacontentcreator Před 2 měsíci

      @@EngineeringAfterHours The gussets would prevent the front and rear frame collapse which is often seen as the wheels bend or fly off. This is important with square tube construction. I think round tube has a strength and weight advantage over square tube though you would need a bender and hole cutter to make good solid welds. I also see that the direct steering in most "boxes" is way too twitchy and needs a second linkage to reduce and buffer the steering input. Perhaps a gear reduction would be a good solution even if the wobbles happen. It also seems that bigger-diameter wheels/tires have an advantage over smaller ones. I love these races and would love to build a car with a team sometime.

    • @EngineeringAfterHours
      @EngineeringAfterHours Před 2 měsíci

      @superbmediacontentcreator that failure mode didn't happen in this case...so it wouldn't have been an improvement but it would have taken time that I didn't have. The frame is also deliberately designed to flex since there is no suspension I think you're over thinking the point of the redbull soapbox races. The car in this case had several failure points deliberately designed in because it was modeled after the crash scene from wolf of Wallstreet.

    Try aiming the gas thruster at a 45 degree angle off the vertical from the mid chassis position. Forward thrust would be less but would result in greater downward force for traction and might reduce mass by eliminating the wheelie bar. my 2 cents worth.

    But anyway, to be on topic to the video, have you explored unsprung aero? That should quickly solve your squatting problem, plus it lets you run softer suspension all around for better mechanical grip at low speeds. Also, RIP GT car body and aero. Thanks for the video on DRS.

  • @Drunken_Hamster

    >24fps >Filming a small, fast moving object **pukes** Please at least use 30. I can give you camera settings to make any frame rate for any type of shot on most cameras look amazing. The main thing you gotta do is ignore the 180-degree rule and instead select a shutter speed in the 1/40th to 1/60th of a second range, and set shutter priority mode if you use auto exposure. You may need to buy an ND filter in order to shoot outdoors in bright situations after locking down your shutter speed like this, in which case, if you only want to spend money on ONE, get an ND16 filter, but if you buy TWO get an ND8 and an ND32. Also, avoid decimal framerates (23.976/.98, 29.97, 59.94) and instead use full frame rates, or at least never get them mixed up in post without properly re-encoding decimal to full. Lastly, avoid non-intra-frame codecs and instead use only all-intra-frame codecs such as ProRes or if you use a Sony camera XAVC S-I not plain S or X. They preserve motion accuracy better AND edit faster/easier on your PC.

    You could use a silicone brush to paint a first layer of the melted candy into the mold. That would let you fill in the details and minimize the air bubbles.
