This KillaJoule model compatible with the popular LEGO™ toy system was designed by Urim Chae, one of my first year engineering students at the University of Auckland. The 562 students in my first year course “Principles of Engineering Design” (ENGGEN 115) were in Semester 1 2018 assigned to design an accessory compatible with LEGO™ in… Continue reading KillaJoule as “LEGO™”
3D printed sidecar skin
Several of the parts on the KillaJoule are 3D printed, and even more of them will be 3D printed on Green Envy. The largest 3D printed part on the KillaJoule is the aerodynamic skin for the sidecar. You can read more about it below. We are also experimenting with a wheel with 3D printed rubber… Continue reading 3D printed sidecar skin
Under the skin – KillaJoule front end and suspension
Deep into the design: Front end and steering I often say that KillaJoule is a “giant cordless drill with wheels”. What I refer to is of course that it is battery powered, but also that it is very simple at a conceptual level. Just like a cordless drill, it has a battery, motor, a throttle,… Continue reading Under the skin – KillaJoule front end and suspension
3D print your own KillaJoule model!
Posted June 1, 2018 If you have access to a 3D printer, you can print your own “engineering action figure set” with the KillaJoule and myself. Click here to download a Zip folder with the .STL files. To open the folder, right-click (on a PC) and select “Extract all”. Both of the models are approximately… Continue reading 3D print your own KillaJoule model!
New record: 248.700 mph (400.2 km/h)!
New speed record for the KillaJoule! The KillaJoule and rider Eva Hakansson set a new international speed record of 248.700 mph (400.2 km/h) at the Bonneville Salt Flats in Utah, USA, on August 31, 2016. The record is 8 mph faster than the previous record that the KillaJoule set in 2014 (no record attempts were… Continue reading New record: 248.700 mph (400.2 km/h)!
Slo-mo MIG welding
There is nothing like MIG welding in slo-mo. I am building a shelf for KillaJoule’s second battery pack that will be mounted in the trailer. #GirlsCanWeldToo

How does it feel setting a record?
“How does it feel running for a speed record?” That the second most common question I receive. The most common is “How fast is it?”. The speed question is easy to answer, the other question is much more difficult. The drive itself is really short, just a few minutes, but can be quite an experience.… Continue reading How does it feel setting a record?
RE-INVENTING THE WHEEL!
The weakest link in all wheel-driven speed record attempts is a surprising and obscure detail – tires! Tires can be one of the main points of failure on all vehicles, but are specifically troublesome on extremely high speed, wheel-driven vehicles. Therefore, we are literally re-inventing the wheel for Green Envy! The very fastest cars are… Continue reading RE-INVENTING THE WHEEL!
