1 week ago by eva_hakansson Today’s much overdue task: taking apart and cleaning off the salt from the #KiWieel wheels. The wheels were relatively easy although tedious to assemble, but much harder to take apart. #KillaJoule #GreenEnvy #EvaHakansson
6 days ago by eva_hakansson I have been busy with community outreach lately, which is a lot of work but also a lot of fun. Talked to a small but very interested crowd at Selwyn College about a week ago. As always, my 3D printed shoes and handbags seems to amaze people more than my world record breaking motorcycle. I think the handbags and shoes are simply more easy to relate to. One of the younger participants tried on the shoes - and they fit perfectly! I think if the shoes fit, you have to become an engineer. ;-) #FlatOutIntoTheFuture #KillaJoule #GreenEnvy #ScienceEnvy #3Dprinting
1 week ago by eva_hakansson Today’s much overdue task: taking apart and cleaning off the salt from the #KiWieel wheels. With the winter coming in the Southern Hemisphere, the higher relative humidity (over 80 % today) will make them corrode like crazy if I don’t get all the salt off. #KillaJoule #GreenEnvy #EvaHakansson
2 days ago by eva_hakansson Off-season health check battery pack - Done! Because we always are on a super-tight budget (hey lecturer salary ;-) ) we are planning to re-use the KillaJoule battery packs in the Green Envy. The BMS (Battery Management System) draws a little bit in standby, and over the off-season it could discharge the battery pack to a critically low level. Everything was fine at this point, but I definitely should give it a charge sometime soon to keep the packs healthy and happy. . . Bill is in Europe (Ireland and France) for a month to finish up two laser-spectroscopy cavity…
7 days ago by eva_hakansson Something _big_ is about to happen. High-strength chrome-moly steel tubing (4130 alloy) being sent off to be laser cut. We have always hand-notched the tubes before to make them fit together, but laser cutting will save us an enormous amount of time and effort. Instead of weeks of work, the cutting will take a matter of hours. Within a few weeks, the Green Envy frame will start to take shape! :-D #GreenEnvy #FlatOutIntoTheFuture
