What are the precations for rain or wet road riding?

I have been browsing the pages of ev conversions for motorcycles. I want to be sure on everything before i make a fiscal commitment. my question is: if it were raining and one were to ride through the rain, how much danger would there be and what things would have to be done to the motorcycle to avoid danger? thank you in advance

DIY Design PWM Contoller for 3 HP 36VDC Motor

A friend of mine and myself want to build a couple of small electric utility vehicles to use for chores around my farm and his cabin. We are thinking of something along the lines of the eMule.  http://www.solarevolution.com/eMule/  We just bought 2 new 3HP 36VDC motors for a really great price off of eBay.  See pics. I want to build some PWM controllers for these to help keep the price of the project down and because I like building things. I could use some help though on a few things. How many amps should the controller be rated for? 100 amps? Larger? Are there any designs out there for a DIYer like me? Thanks.

I got a siren!

A little over a month ago, my dad got a siren on eBay. It's the Wolo Model 345, about halfway down the page. Note: if you want one, go through eBay, Wolo wants $64, but this was brand-new for $20. It's not Instructable-worthy, and I don't have enough pictures to make a Slideshow, so I'm using the Forums for their original use. We were originally going to put this on my mom's ZAP Xebra, because it's completely silent and we wanted a way to warn walkers of her approach, but she didn't like it, so I got it to put in out Ford Courier. Since it's electric, I only go 39 in a 40 mph-zone to save range, so I'm often cut off by people going 45. Being electric, the truck has no radiator, just a flat plate of steel. We were already going to paint it black, so we mounted the horn speaker in there. There is an instrument bay overhead, so I stuffed the control box inside an empty slot. Eventually I'll take off the plastic case and mount it in the aluminum sheet to make it much cleaner, but this is fine for now. There were already two extra switches that did nothing, but already had an always-hot line running to them, so I wired it in to that. It can do sirens, animal noises, or a PA. I'm leaving it set to a police-style siren, so if someone cuts me off, I can just flip the switch and give a short blast, then watch them look around for the police car. If I have more time, I can just use the PA to yell at them. Other potential use: I'm going to make a CD of engine sounds. That way I can make my electric sound like an idling Harley at a stoplight. Or a turbine engine. Or a semi. Or a whatever.

Chosing a Motor for EV Motorcycle

I am thinking of building a EV Motorcycle. But I don't want to make any finical commitment unitl I know exactly how much I have to pay.my question for the day is:i see many motors, and motor controllers that "support regen" i know what regen is, and i don't want a bike without it. but do i have to match a motor that "supports regen" with a controller that "supports regen" or can i just buy any motor with the proper voltage and buy a "regen" controller.i realize that i would be very convient to use a kit like http://www.robotmarketplace.com/products/ETK-ETEKBL250.html but if i can drop the cost, by useing other sites that would be great if you have prefered sites for specific products, that would be great.-thank you for you time.

speed vs. distance?

Hello All, I am considering building a electric motorcycle in the next year, all the Instructables I have read on the subject boast top speeds of 70 mph and a 10 - 20 mile range. I live in a small city in Canada where the maximum speed limit is 50KMh(~30mph) and the city is not even 7 miles across, also there is nothing outside the city that is close enough to get to with a ev such as this. My question is how does the speed and distance connect, for example, if I was to travel at half the speed would I be able to expect to get double the distance?

VFD DC bus input

So I've heard it is possible to use a high voltage DC input with a 3 phase motor controller, but I haven't really found much info or instructions on how to modify them to be able to take a DC current. I am interested in this because I want to experiment with building an electric vehicle and a industrial motor. I bought a cheap, used VFD and a motor to experiment with, but it would be great to have some info and tips on how to go about doing this!

Battery charger help

As some of you may already know, I'm planning on building an electric car this summer. Its all planned out, but instead of using regular transformer based chargers I was wondering if someone could help me design a transistor based charger to reduce weight. Requirements 48 or 72 volts Needs to charge marine deep cycle batteries over night Needs to not have a transformer. Needs to be relatively small (under 1 cubic foot) Needs to be simple enough for me to build myself (I can do it if you can design it) Can anyone give me some links or some good schematics for this? Thanks

Not as cute as Womble...but he comes close!

*see here and here if you don't know your Instructables history* This is my family's new-old Cushman electric vehicle. Yes, it's the same sort of thing you see reading parking meters downtown. Yay for tiny awesome cars that don't use gas! Any ideas for fun modifications? Plans so far include having a silly little decal printed for each side with an amber light on top so we look official, and mounting some 12V air horns in there to rattle the hubcaps off the jerks that pull out in front of it (We already mounted an electric ooga horn in my mom's Xebra SD, but air horns are so much more fun). Cardboard rockets that fire off of compressed air have also been proposed. He also has no name yet...we'll be working on that...

Regen Braking Motor Controller

Good morning.... Quick question regarding motor controllers with the facility of regen braking..... For a project of mine I am creating an EV (with a dune buggy chassis), which needs a system to recharge the batteries when been driven or 'towed' by an external force. I've been looking at a 4QD motor controller, which has the regen braking system already built in. My idea is to use the back EMF to charge the batteries. This in theory is quite similar to regen braking, having done a bit of research, and also with some info from the 4QD site itself. I know that if the back EMF is to great, I risk damaging the motor controller. But if there was a way to regulate the back EMF (either by controlling the speed it is been externally driven or with use of electronic circuitry), could I essentially recharge the batteries using this motor controller???! Thanks in advance, Dave

DIY Plug-In Hybrid Pickup Truck

Hi everyone, For a while, I've had this as my "back-burner" project. I'm trying to really get going on it now. It's an Open Source, DIY, Plug-in Diesel/Electric Hybrid Pickup truck. That's really a mouthful, so I'm just calling it the "SuperTruck" project, until I can come up with a better name. The entire concept is that it is a parallel hybrid, which you can charge from the wall, and it has a diesel engine that can run on diesel, bio-diesel, and possibly veggie oil. Either the engine OR forklift motor will be able to propel the vehicle. (Meaning that it will have a dedicated EV mode.) The driver can manually decide to run it on diesel, electric, or both depending on the driving situation. The mechanicals are relatively simple. It uses a manual transmission (rather than a CVT or planetary gearing.) In theory, this will be a project than any advanced grease monkey will be able to duplicate. I'm not much of a car guy, but I have learned quite a bit working on my electric motorcycle, electric car, and experimenting with running my car as a hybrid. Here's a YouTube playlist of what I've got going so far. For the latest on this project, please visit the page for it on my blog: http://300mpg.org/projects/supertruck/ I'll definately need help on this project, so please tell all your friends about it!

Free EV1 Charger

I have an edison EV charger.  It has been disassembled and does not include the cable or the connector.  It is in Michigan and I am not really excited about shipping it.  It is, however, free if you want to tinker with it or if you want a piece of EV history.

Electric Handicap Scooter parts, any ideas???

Heya guys I just aquired and parted out a electric handicap scooter from a rummage sale for 20 bucks. It is a three wheeler. Batteries are dead (read, toast). Im tring to figure out what to so with the gearbox/motor assembly. It is all one unit. Im trying to think of some kind EV project. I thought perhaps putting some larger 26in wheels on the axle ends to gear it up, and make some sort of cargo trike. Any other ideas would be appreciated

Managing high-voltage lithium-ion batteries in HEVs

From EDN (Electronic Design News), comes this article: Skyrocketing energy prices and the growing concern over carbon emissions have focused attention on electric and hybrid-electric vehicles. New lithium-battery designs will be key technologies for efficient EVs and HEVs.By Michael Kultgen, Linear Technology Corp -- EDN, 4/9/2009Safely getting the most energy and lifetime from a lithium cell requires some sophisticated electronics. One requirement, for example, is the ability to measure the voltage across every 3.7V battery cell in a stack of 100 series-connected cells. How do you cope with the 370V of common-mode voltage and reject 100V of common-mode switching transients? The design of battery-management systems for EV (electric-vehicle), HEV (hybrid-electric-vehicle), and UPS (uninterruptible-power-supply) applications requires solving many such problems.How do batteries make cars "green," ...http://www.edn.com/article/CA6648791.html?nid=2432&rid;=8848980

I just want to make sure that the victims are never forgotten, and I take this moment to remember the fallen, and those firefighters, police officers, EMT, who all risked their lives to save those trapped. Thanks for taking the time to remember, and I hope some point tomorrow you share a moment of silence with the world to remember. *silence*

Antique megawatt meter (Westinghouse). Anybody ever seen anything like this?

Picked up this barn-find in Cleveland, OH recently. I've tried finding any info on it to no avail.

I'd love to find a picture of it or if anybody knows anything (or anyone who might know) please pass it along!

Current Consumtion by a DC Motor?

 I am asking few questions EV related, more current related. Let a consider a dc motor rated 4hp at 24v and 2hp at 12v. So is there a way to calculate ampere draw of the motor at various loads.(like no load, full load, or any load). And if we know the full load current of the dc motor then can we calculate the max load for the dc motor. Next as the dc motor is 2hp at 12v then will this value be constant or will the motor be able to produce 4hp at 12v even rather than at 24v. And will a battery eg 50ah be able to supply more then 50amp.

For the circumstances are perpetually favorable. I last night slept in my waking attire as if I cared not. I utilised a motorized stage, indifferent to the destination. I shall participate if you favor dancing this eve. For the circumstances are perpetually favorable. Good morn and good night. I shall arise at dusk. Events will yield acceptable outcomes.

Interesting...

A while back you may (or may not) have seen this Japanese electric motorcycle prototype called the EV-X7. It was advertised to use a "Super Electric Motor" that was the combination of a permanent magnet and an electromagnet (isn't that was a motor is?) which would allow the vehicle a range as much as 180 kilometers (111.846815 miles) on one charge with a top speed of about 150 kilometers per hour (93.2056788 mi / hr).A few sources said that in about a year they would start producing a smaller version... That was 2007, and the company's website doesn't look very promising...Ok, so now what? Too bad, eh? Well, yes...However, the research company, Genesis, seemed to have posted something on their website:Translated WebsiteAnyone wanna see if they can build one? =D

smart window thermostat

Wanted: circuit to open window at night when it is cooler outside than in. Close it when hotter outside in morn. Probably add something to prevent it from opening and closing several times in the eve and morn with random fluctuations. Prefer 2 thermostats, 1 outside, one in, rather than a timer. I've a vague recollection of a circuit with 2 potentiometers, one on the motor, one on the control panel, such that turning the control pot will activate the motor until its pot is at the same position as ctrl pot.. Could a circuit something  like this control my window? But most thermostats are on/off, not continuous variable.   It would be simple to do a switch logic thing like:  “IF thermo ‘I’ is above 70 AND thermo ‘O’ is below 70, THEN OPEN “  but that only works at 1 temp.

That is very annoying. What can I do? Either of the below images help explain what is going on, even if the user never looks at my instructable.  So I much prefer if one of those is seen by the ordinary man in the street.  Thanks Brian

Electric car battieries

Hello, I need some help. With gas prices getting to an excess of $3.50 in Texas, I have decided to make the switch to electric cars. I was watching a show on TLC the other day about a guy in California who converts cars to electric. He converted an old heavy-as-can-be Camaro into an electric car that could peel out. I found a website that sells conversion kits for all kinds of cars called Cloud EV. I want to buy the heavy car kit, but the only snag I hit was this: I need 60 batteries to get a day's power, but it will cost about $3000 to $5100 (1949.6978 Euros to 3314.48625 Euros)!!! Can anyone help me find a cheaper source of batteries? Car batteries are just to expensive. Thanks.

I just took a ride in an awesome truck

Here's some photos from the new model from Topeka Electric Motors. It's a 3/4 ton Chevy pickup with a gigantic motor and a boatload of lithium batteries, with an automatic transmission, power steering, power brakes, A/C, etc. The motor on this thing is HUGE...a foot or so in diameter. This is a truck that could tow a cement mixer. They're using it as a work truck to deliver electric motors, pumps, and everything else they work on. I took a ride in it this morning, and it runs smoother than a gas truck. This is the brainchild of a few smart guys at Topeka Electric Motor. These guys are tuning the shift points for an electric motor to get maximum power and efficiency, programming the controller to perfectly match what the motor needs, and basically making a vehicle that beats the pants off anything the big companies with hundreds of engineers have put out.

Merry Knexmas! From Hiyadudez! It's almost here, Christmas, one of the happiest times of the year.

Hehe :-) Anyway, I only made this because I was bored, cya!

My candy Cane Fudge however *sigh* *face palm* I deceided to make my Christmas treats into I'bles and Entries into the Christmas Gifts contest...So as I 'baked' I snapped away on my camera. Everything was going well until I was knocked by my dogs whilst adding the food colouring, so that it looked like a rainbow had vomited into my mix... then to add insult to injury, I dropped the cooling mixture on the way to the refridgerator.... Luckily I cought my camera... but the fudge was... well.. beyond repair. What I wan't to know, is if you have ever had a disasterous I'ble attempt, and have you posted it? -Biggsy Cheerio

(let's assume we all ride the bus) ...Would you take on the position of leading a movement for democracy in a country that you could could easily be assassinated in for doing it? ...Would you give up everything to fight for what is right? People who have answered yes to questions like these have gotten the modern world to where we are today. People who have answered yes to questions like these are improving the undeveloped world. Would you? If the occasion came that you were best fit to take on a position like Martin Luther King Jr. did, would you accept? I like to think that I would - I hope that I would. --ChaosCampbell put it well: "so... simply put, you are asking; would you stand up for yourself. eve at the sacrifice of your life. I think our world as we know it shows the majority answer of... yesthe question that would bring a majority ... no answer, even if we cannot admit it to ourselves would be; would you be willing to sacrifice everything to resolve an injustice committed against a fellow man, if your sacrifice would bring a group further at the detriment of your own existence. meaning doing nothing would allow you to live a merry life, or sacrificing would allow a larger group to have a better life at your expense"

Deriving the maximum range and angle of a projectile

In a thread in the Green group, AnarchistAsian and I were discussing his coil guns. I posed the question of what range he could get, and he asked me to go through the physics derivation. Here it is, simplified to require just algebra and trig.The kinetic energy of the projectile E = ½mv2, gives v = sqrt(2E/m) as the speed at launch. Let θ be the angle at which you launch (θ=0° is horizontal, θ=90° is straight up). Then you can decompose the speed into two components: vh = v cos(θ) is the horizontal speed,vv = v sin(θ) is the vertical speed.Gravity only pulls vertically, so the projectile's vertical speed will be slowed down until it reaches its maximum altitude, then it will fall back until it hits the ground. The horizontal speed will remain constant until it hits the ground and stops. To figure out the range, you need to know the time t that the projectile flies before it hits the ground; then the range is just R = vhtEnergy conservation guarantees that it's downward speed at the end is equal to its original upward speed, just with a change of sign. That also means that the total flight time of the projectile will be half going up and half going down. Once you determine how long it takes to reach the top of its flight, you're done; just double that answer :-)In the vertical direction, the maximum heightH = vvt - ½gt2(you need calculus to derive this result). From energy conservation, the initial kinetic energy in the vertical direction, Ev = ½mvv2 must equal the potential energy at the top of the flight, Pv = mgH:mgH = ½mvv2H = ½vv2/gSubstitute this on the left hand side of the trajectory expression,½vv2/g = vvt - ½gt2vv2 = 2gvvt - g2t2vv2 - 2gvvt + g2t2 = 0(vv - gt)2 = 0vv = gtSo, t = vv/g = v sin(θ)/g is the time to reach maximum height. Double that as discussed above, and you get the range R = 2 sin(θ) cos(θ) v/g.Work out the angle that gets you maximum range by just plugging in different angle values and finding the one that is biggest.

Walking with Dinosaurs

WALKING WITH DINOSAURS the Live Experience is no longer produced or presented by Immersion Edutainment -- please revise your copy appropriately. For 200 million years the Dinosaurs ruled the earth Now, they’re back roaming the arenas of America in an extraordinary new theatrical production WALKING WITH DINOSAURS – The Live Experience Based on the award-winning BBC Television Series Now on a two-year North American tour June 10, 2008--- Dinosaurs once again roam the earth in a spectacular theatrical arena show, WALKING WITH DINOSAURS – The Live Experience, based on the award-winning BBC Television Series. WALKING WITH DINOSAURS – The Live Experience is now on tour in North America. Over one and a half million Americans have already seen the production since it opened in July 2007. The show originated in Australia, where after years of planning, WALKING WITH DINOSAURS came to life at Sydney’s Acer Arena in January 2007. The show proved itself such a sensation, that this North American tour was fast-tracked. It began a short three months after completing its sold out engagements in Australia. WALKING WITH DINOSAURS – The Live Experience is brought to North America by The Creature Production Company, headed by CEO Carmen Pavlovic. Pavlovic said, “The BBC Series was a brilliant blend of special effects, escapism, excitement and information. Our show brings together all of that, plus something extra - it’s live! In this production, fifteen roaring, snarling “live” dinosaurs mesmerize the audience – and are as awe-inspiring as when they first walked on earth.” Pavlovic continued, “The dinosaurs are life-size, making the show so immense, it could only fit in arenas. It’s a $20 million arena spectacle of unprecedented size and quality, which captivates young and old alike. With Walking with Dinosaurs, we really believe we have created a new genre in entertainment and we hope to continue to bring new product to arenas for years to come ” WALKING WITH DINOSAURS – The Live Experience has sold out performances and broken records in arenas all over the America – generating more than $50 million in ticket sales to date. It has been seen on "The Today Show," Good Morning America," "Live with Regis and Kelly," and has been written about in Newsweek, The New York Times, the Christian Science Monitor and the Wall Street Journal. It was the subject of a Discovery Channel Really Big Things episode and a video clue category on Jeopardy. more WALKING WITH DINOSAURS - Page 2 The production has won the 2007 THEA Award for Outstanding Achievement in Touring Event. The THEAs recognize excellence in the creation of compelling educational, historical, and entertainment projects. Artistic Director William May developed the creative vision of the show based on an original idea by entrepreneur Bruce Mactaggart to create an arena version of the Walking with Dinosaurs television series. A talented and experienced team of creative artists came together to produce WALKING WITH DINOSAURS – The Live Experience. The show is directed by Scott Faris, a Broadway veteran who has worked side by side with Harold Prince, Trevor Nunn, Michael Blakemore, Gene Saks, John Caird, Tommy Tune and Jerry Zaks. The creatures are designed and built by Sonny Tilders; the set and projected image design are by Peter England; the show’s lighting is by John Rayment, our score was composed by James Brett; and Warner Brown wrote the script. Tim Haines, creator and producer of the original BBC series, which was seen by a worldwide audience of 700 million, serves as Project Consultant to WALKING WITH DINOSAURS – The Live Experience. The series won six Emmy and three BAFTA Awards. Ten species are represented from the entire 200 million year reign of the dinosaurs. The show includes the Tyrannosaurus Rex, the terror of the ancient terrain, as well as the Plateosaurus and Liliensternus from the Triassic period, the Stegosaurus and Allosaurus from the Jurassic period and Torosaurus and Utahraptor from the awesome Cretaceous. The largest of them, the Brachiosaurus is 36 feet tall, and 56 feet from nose to tail. It took a team of 50 – including engineers, fabricators, skin makers, artists and painters, and animatronic experts – a year to build the original production. The show depicts the dinosaurs’ evolution, complete with the climatic and tectonic changes that took place, which led to the demise of many species. With almost cinematic realism, WALKING WITH DINOSAURS has scenes of the interactions between dinosaurs, and the audience sees how carnivorous dinosaurs evolved to walk on two legs, and how the herbivores fended off their more agile predators. The history of the world is played out with the splitting of the earth’s continents, and the transition from the arid desert of the Triassic period is given over to the lush green prairies and forces of the later Jurassic. Oceans form, volcanoes erupt, a forest catches fire -- all leading to the impact of the massive comet, which struck the earth, and forced the extinction of the dinosaurs. Variety said, “The dinosaurs are stunning, life-size and faultlessly nimble. In act one, the beasts parade into the arena gnashing and cavorting as a safari-suited paleontologist describes their attributes … in the second half, the action cranks up, culminating in a spectacular clash as a T-Rex mom defends her baby from predators. Sonny Tilders' triumphant creature design ensures ‘Walking With Dinosaurs’ is a truly spectacular spectacular. It is everything a dino-phile could want.” The New York Times said that in this show dinosaurs make "a thundering comeback after 65 million years." Gloria Goodale of the Christian Science Monitor said, “When the dinosaurs start pouring out onto the stage, if you don’t have to stifle the natural flight response of any living breathing being, then it’s your pulse that needs checking.” Newsweek called the show, "that rare entertainment beast that parents and kids can enjoy together." More WALKING WITH DINOSAURS - Page 3 It took artists and technicians one year to build the show. The 15 dinosaurs were originally “hatched” by Tilders, the head of creature design, in a Melbourne Docklands workshop big enough to park a 747. For the North American tour, the only building large enough to house rehearsals for the dinosaurs – some as large as 36 ft tall by 56 ft long, was the Greater Tacoma Convention and Trade Center! Artistic Director William May is known around the globe for co-producing shows with Malcolm Cooke for the past 30 years, including The Hobbit and The Lion, The Witch and the Wardrobe. He produced Marilyn An American Fable on Broadway and co-composed and wrote the musical Always for the West End. Director Scott Faris directed Michael Crawford in EFX at MGM Grand Hotel in Las Vegas, which at the time was the biggest stage production ever conceived, and was on the production team that created Siegfried & Roy at the Mirage Hotel. Faris has directed Chicago the Musical in 16 countries around the world in over a dozen languages. Most recently he directed Bette Midler in her new Las Vegas show, The Showgirl Must Go On at Caesars Palace. Faris said, "We take the audience on a journey back in time and show them how the dinosaurs might have actually looked in their prime - huge, sometimes frightening, sometimes comical monsters - that fought for survival every day of their lives. Our dinosaurs move exactly like they are real -- with all the roars, snorts and excitement that go with it. The realism is mind-blowing!" Sonny Tilders, who designed and built the creatures has been, for the past decade, one of the major creative forces of the high-tech world of animatronic puppetry for film and television. He was one of the lead animatronic engineers for Jim Henson’s Creature workshop on the Farscape series, followed by work on Star Wars: Episode III – Revenge of the Sith, Peter Pan, Ghost Rider and The Chronicles of Narnia. Tilders said, “Many of the technologies we are using on WALKING WITH DINOSAURS – The Live Experience are borrowed from film. The computer software and hardware we have developed is based on the systems used to control animatronic creatures in feature films.” “To make it appear that these creatures are flesh and blood weighing six, eight or even 20 tons, we use a system called ‘muscle bags,’ made from stretch mesh fabric and filled with polystyrene balls, stretched across moving points on the body. These contract and stretch in the same manner that muscle, fat, and skin does on real creatures.” “The puppeteers use ‘voodoo rigs’ to make many of the dinosaurs move. They are miniature versions of the dinosaurs with the same joints and range of movement as their life-sized counterparts. The puppeteer manipulates the voodoo rig and these actions are interpreted by computer and transmitted by radio waves to make the hydraulic cylinders in the actual dinosaur replicate the action, with a driver hidden below the animal, helping to maneuver it around the arena.” Suited puppeteer specialists, who are inside the creatures, operate five of the smaller dinosaurs. More WALKING WITH DINOSAURS - Page 4 Warner Brown wrote the script of WALKING WITH DINOSAURS – The Live Experience. He is an accomplished writer whose works include the book of the musical Flickers on Broadway, the screenplay of Nijinsky for Regent Entertainment, the musical The Black and White Ball, which features music by Cole Porter and The Truth About Light, written with composer Jimmy Roberts. Other credits include a new version of Half A Sixpence for the West End in 2008, Garbo – The Musical with music by Jim Steinman and Michael Reed, playing in Europe, and the plays and musicals Scandal, The Biograph Girl, Six for Gold, Cinderella, Talullah for a Day and Dance for Life. The score of WALKING WITH DINOSAURS – The Live Experience is by James Brett whose work can be heard on soundtracks including 10,000 BC, Alien vs Predator, Miramax's Ella Enchanted and the forthcoming UK feature Outpost. He also helped create the groundbreaking collaboration between Metallica and the San Francisco Symphony. The album S&M has sold over 5 million copies worldwide. The sets and projections are by the multi-award winning designer Peter England whose work has toured the world extensively. A frequent collaborator at Opera Australia, the Australian Ballet and Bangarra Dance Theatre, he also designed sections of the 2000 Sydney Olympic Games Opening and Closing Ceremonies, three City of Sydney New Year's Eve Celebrations and in 2002 was a finalist in the international design competition for the Pentagon Memorial in Washington DC. Lighting Designer John Rayment lit the Opening and Closing Ceremonies of the 2000 Sydney Olympic Games; Hong Kong’s original A Symphony of Light, a massive cityscape permanent lighting display involving over 18 buildings; Singapore’s 2002 National Day Parade stadium event; and Singapore’s Marina Bay annual New Year’s Eve Countdown display. Rayment also works frequently at Opera Australia and has lit 30 productions for Sydney Dance Company.
