Inflate a basketball in an illegal sized fuel tank. With the filled basketball displacing space in the tank, the tank holds the required amount of fuel to pass tech. Once you've passed tech, you deflate the ball, and top off the tank.

Half the NASCAR rules are specifically outlawing things Smokey Yunick got away with once. There's also the 7/8-scale car, and another one with the same body as his daily driver so he could take the officials out to the parking lot and show them it was a real car when they called him on it. Speaking of racing, they lost the first-place car at Le Mans for half an hour or so in the wee hours of the morning local time. Apparently it had an electrical problem and the lights went out, so all the commentators knew was that it was stopped, but couldn't get a camera on it. How do you lose a loving racecar in this day and age? It just crapped out and pulled over and they couldn't find it. Like, I could understand losing a '99 Mercedes up a tree, but it was right there the whole time. Edit: '99 Mercedes loving off into a tree: https://www.youtube.com/watch?v=SFN_Gp1eHN0 Cf '90s NASCAR before the roof spoilers. The car's shaped like a wing, disrupt the airflow and it takes the gently caress off. Chillbro Baggins fucked around with this message at 06:13 on Jun 15, 2014 |

F1 has some pretty awesome mechanical failures. What do you do when you are behind the game, with a car of dubious reliability and speed? Slap a giant exhaust fan on the back of the car to suck air out from underneath it, vacuuming it to the track.   http://en.wikipedia.org/wiki/Brabham_BT46 The two modified cars were prepared for the Swedish Grand Prix at Anderstorp on 17 June 1978, for Niki Lauda and John Watson. When not in use, the fan was covered by a dustbin lid, but it soon became clear what the modified Brabham was intended to achieve: when the drivers blipped the throttle, the car could be seen to squat down on its suspension as the downforce increased. According to Ecclestone's biographer Terry Lovell, the heads of the other FOCA teams, led by Colin Chapman threatened to withdraw their support for Ecclestone unless he withdrew the BT46B. Ecclestone negotiated a deal within FOCA whereby the car would have continued for another three races before Brabham would voluntarily withdraw it.[18] However, the Commission Sportive Internationale intervened to declare that henceforth fan cars would not be allowed and the car never raced again in Formula One. The car was not considered to have been illegal when it raced however, so the Swedish Grand Prix win stood. The two converted chassis were returned to standard BT46 configuration for the next race.

There is also the Tyrrell P34 (Do androids dream of race cars with 6 wheels?) The Tyrrell was reasonably competitive, but because it used special sized tires, tire development quickly lagged behind other teams. The weight of an entire extra front suspension didn't help matters either. While incredibly recognizable, It is an objective failure, only ever winning 1 race out of 30.

Finally, my dad helped me out and now it's all fixed - by replacing the power supply in my computer with a model that doesn't have that feature. The reason for this btw is because of the shape of the power that the UPS outputs. Power supplies with power factor correction need sine waves while before they were okay with the really choppy outputs that many cheap UPS' output. This is unfortunate because most (all?) high efficiency power supplies these days have power factor correction so if you want to have a efficient power supply you're basically stuck with a more expensive UPS that can output a sine wave.

The sine wave output UPS's are more efficient though, and for modern PCs they are worth it, just for the reduction of stress on the computer PSU. Anyway, sorry for the detail, post more broken poo poo!  oooops, he made it through though. Made a noise!

Funny thing is that because of the rectifier design, a full-on squarewave UPS output is ideal for non power factor corrected PSUs. Stepped sine just sucks, but is better than sine. For A-PFC, it depends on the design, I guess. Depending on how smart the controller is (if it's just reacting to input voltage change, or using a sine wave reference and a feedback loop to react to minor changes, really) it may or may not matter at all. For more info on how power factor correction works, and how a certain APFC controller chip I like works (this is for hardcore EE nerds only, really, I guess) see this document: http://www.onsemi.com/pub/Collateral/HBD853-D.PDF

Cross-posted from the Alternative Insanity thread, a mechanical failure caused by using a consumer product well outside of its design specifications (my fault): The first attempt at building a vacuum pump powered oil extractor did not work. I was concerned that I might not be able to maintain a good seal with a plastic container and fittings from the hardware store and also that the vinyl tubing might collapse under vacuum. I had a different problem. I used a brand new Home Depot orange 5 gallon bucket with a gasketed lid. I drilled two holes and put brass barbs on the inside and outside of the lid. One set of barbs had a hose going from the exterior barb to the oil pan (or dirty oil container, whatever) and a hose from the interior barb to the bottom of the bucket. The other set of barbs had a hose connecting the exterior barb to the vacuum pump and nothing connected to the interior barb. I connected everything and switched on the vacuum pump and there was suction on the "dirty oil" end of all the tubing. I submerged the same end of the tubing into a container of (cold) old oil and that is where the trouble started.  I could see oil moving through the tubing from the waste container (trial oil pan) to the collection bucket right away, but the bucket was not able to withstand the vacuum pressure developed by the vacuum pump. The bucket caved in and the movement of the oil stopped. The vacuum pressure pulled one of the barb sets through the lid of the bucket, which was a surprise. It seems that I need a stronger vessel for collection. In hindsight I wonder if this device would have worked if I had shut off vacuum pressure as soon as the oil started moving. There was no mess or anything, the only thing ruined was the bucket. I think I will try again with a two gallon garden sprayer as the collection vessel. Any other ideas?

It sounds like the pump was pulling far more air than could quickly be replaced by the oil. I'd say either get a larger diameter hose and fittings, or pulse the pump next time. As long as there isn't any backflow from the pump, the oil will flow into the bucket until the pressure equalizes.

I plan on removing oil from warm engines in the future, this was only a test. I couldn't think of an easy way to warm up the skunky old oil in the jug. I will try pulsing the pump also.
