GPS lap timer from secondhand parts

gps_racing_lap_timer

Hackaday forum member [nes] was training for an endurance race, and rather than having someone verbally call out his lap times, he wanted something he could keep in-vehicle to help keep track of his performance. With the race budget running dry, he and his teammates needed something cheap, if not free, to get the job done.

He scored a “broken” GPS receiver on eBay for a measly £4 and found that the receiver worked, but corrupted software prevented the unit from mapping routes. Since he didn’t require routing functions to keep track of his lap times, he splayed the GPS receiver open and started hunting around for a serial bit stream. He found what he was looking for after a bit of probing and hooked it up to his computer to see if the data contained NMEA sentences.

He cut the receiver down to the necessary parts and then started work on the lap timer itself. The timer uses an ATMega32 to run the show, displaying relevant time and location information on an LCD panel he scavenged from the trash bin.

He admits that the wiring is a bit questionable, but says that after about seven hours of rough use, everything is still intact and working great.

MIT’s eSuperbike takes on the Isle of Man

mit_ebike

While the Isle of Man typically plays host to an array of gas-powered superbikes screaming through villages and mountain passes at unbelievable speeds, the island’s TT Race is a bit different. Introduced in 2009 to offer a greener alternative to the traditional motorcycle race, organizers opened up the course to electric bikes of all kinds. In order to entice participants, they even put a £10k prize on the line for the first bike that completes the race with an average speed of 100 miles per hour or faster. While no one has claimed the prize just yet, that didn’t stop the MIT Electric Vehicle team from tossing their hat into the ring this year.

Their entry into the race is the brainchild of PhD student [Lennon Rodgers] and his team of undergrads. They first designed a rough model of the motorcycle they wanted to build in CAD, and through a professor at MIT sourced some custom-made batteries for their bike. Through a series of fortunate events, the team found themselves in front of BMW management, who donated an S1000RR racing bike to the project. After a good number of alterations, including the addition of an Arduino to control the bike, they were ready for race day.

While the team didn’t take the checkered flag, they did finish the race in 4th place. Their bike managed to complete the course with an average speed of 79 mph, which isn’t bad according to [Rodgers]. He says that for their first time out, he’s happy that they finished at all, which is not something every team can claim.

DIY Racing Sim shift box

diy_pc_racing_shiftbox

Ask anyone who has ever owned a car with a manual gearbox – in real life and in video games, nothing beats stick shift. Rather than shell out gobs of money to purchase a pre-made shift box, forum member [nikescar] built his own for about $20.

Using some scrap wood and a plastic cutting board, he went to work building a prototype. The “H” shift pattern was designed in CAD and laid over the cutting board, which was hand-cut with a Dremel. Using some tips found online, he constructed a simple shifting mechanism, then wired in a cheap USB game pad found on Ebay. Using safety pins as temporary micro switches, he ran a few laps, and was quite happy with the results. Once the switches arrived, they were fitted to the shift box and it was off to the races.

[nikescar] reports that the shifter works extremely well, allowing him to row through the gears with the greatest of ease, sans any fear of breaking things. Keep reading to get a better look at the shift box internals.

Racing sim cockpit stores inside an ottoman

[Lyscho] built a racing simulator cockpit based on a PVC frame but it took up a lot of space when not in use. His second generation is built inside the frame of an ottoman, meaning it can be stored right under your feet.

The pedals are fixed in place, with some padding below to rest your heels on. The cockpit chair and steering wheel are both adjustable to suit different drivers. They use a routed groove along with wing nuts and bolts, making it easy to slide them for adjustments. The ottoman itself is [Lyscho's] own creation, which just needs power and USB when in use, and has a padded top when not in use.

If you can’t use a real car as the simulator this is fantastic alternative.

Racing game uses a physical race track and vehicle

Racer is a racing video game with a very real element. The player sits in an arcade-style console; wheel, pedals, shifter, and television display. But in what must be an homage to Tron the game taking place is very real. You can see the track above, designed in CAD and cut from cardboard, which is navigated by that little vehicle the gentleman holds in his hand. It’s wireless and broadcasts video back to the control console. What we have here is a homemade drone but for now it’s confined to the gaming grid. Don’t miss the demos after the break.

Mini racing cabinet

Here’s another small arcade cabinet. This time around it’s the racing simulator Daytona USA. [Pocket_lucho's] cabinet work has been featured before and he did some fine work with the control interface on this build. The wheel is from the controller of an RC car and the gear lever from a heavily used toy. He fashioned two pedals using gate hinges and a couple of leaf switches. The guts pack quite a punch with a mini ITX motherboard running the show. This will look great next to Ms. Pac-Man. Check out the video after the break.

Racing sim with real car parts

[Alex Rosiu] picked up this instrument cluster from a 1992 BMW. After some trial and error he’s hooked it up for use with a racing simulator. You can see how amazingly well it works in the video after the break. An Arduino Mega takes incoming data from the PC and actuates the appropriate indicators on the module. [Alex] didn’t stop there. He got his hands on a full dashboard and is working on fitting a joystick in as an H shifter. Keep an eye on this one, we think it may one day become a full-blown motion simulator.
