Thank you Airtech!

A sampling of donated Airtech materials.

We are super excited to announce that Airtech recently became a large materials sponsor of CalSol! The largest manufacturer of vacuum bagging and composite tooling materials, Airtech has generously donated some of their materials for our use on Zephyr’s shell. Since we have decided to go with pre-imprepregnated carbon fiber this time, we needed all new bagging materials that can withstand the elevated curing temperatures. We’ve also upgraded some of our other equipment, which will hopefully allow us to make an extremely nice shell for Zephyr.

Our new partnership with Airtech will give us the opportunity to improve our manufacturing process as we get ready to build CalSol’s most competitive vehicle yet. Thank you Airtech!

Here at CalSol, safety is our #1 priority. For several months now, we have had to make do with handheld walkie talkies for communications between Impulse and the accompanying safety caravan. This system has given us many a headache because of problematically low sound quality which had no chance competing against the noisy clicking and whirring of our NGM SCM150 motor at low speeds and the wind at high speeds. With clear communication being one of the best defenses against the possibility of unsafe situations, we started to search for new methods of relaying messages between Impulse and the caravan.


Painted Perfection

Impulse with a Fresh Coat of Paint from SAC

After working on numerous repairs to Impulse’s aerodynamic exterior, including making a new canopy out of carbon fiber composites instead of PETG plastic, we dropped off Impulse at Shattuck Auto Collision Center (SAC) this past Monday, and waited excitedly to see her return with a brand-new paint job. This morning our wait was finally over, and we picked up a sexy-looking Impulse from SAC. As always, we are very impressed by the great job done by SAC, who not only made Impulse look great, but also smoothed out any remaining textures to give her a sleek and aerodynamically favorable painted outer surface. Since every bump or tiny hole will add up to produce more energy loss from aerodynamic drag, the smooth surface finish is a great help in boosting our aerodynamic performance.

Nicole looks pretty happy with the new canopy!

Now we are working hard on last-minute preparations for Cal Day (which is next Saturday!!), including reattaching some solar cells that were removed during the canopy repairs and putting on new sponsor logos. We are also hoping to get some testing done in this wonderfully sunny weather, leading up to a test drive next weekend to Sacramento, right after we show off our car in the Etcheverry breezeway. We invite everyone to come out and see Impulse, with her new paint job, next weekend from 10AM-3PM.

Thanks again SAC!!

New Electrical Equipment from KIT Digital

Loading the truck with Chris

On Monday, we got a very generous donation from KIT Digital. After KIT Digital’s purchase of Sezmi, the company went through some internal changes and ended up with a fairly sizable collection of unneeded electrical equipment. They got in contact with us, and arranged to donate all of this equipment to CalSol.

This donation will be invaluable in augmenting our existing setup and aging equipment, and I’m excited to go through it all and inventory everything. I’ve only had time to briefly look over the contents, but from what I’ve seen I can say that we will be able to put everything to good use.

Some of the equipment we picked up from Kit Digital

All of this was made possible because of Chris Hagler, an employee of KIT Digital and a friend of our very own team member Jessica Chang. Chris thought of us when he came across the electrical equipment, and arranged everything on KIT Digital’s side to make this donation possible.

KIT Digital is now our newest Gold Sponsor! It’s because of companies like you that CalSol can thrive.

Linear Technology in a Time of Need

Sunday, March 11th, 2012

Last week, we were working on improving our Battery Monitoring System, and ran into a few problems. High voltage went a few places that it wasn’t supposed to, and we were left with several boards in less-than-perfect working condition. The damaged boards were manufactured by Linear Technology, and were used to individually monitor each battery cell module in our battery box. Each board would read the voltage of a dozen modules and constantly balance them to prevent overcharging or undercharging any cells. Our car has 35 battery modules, each of them at a nominal 3.6V. After working on the problems for several days, we came to the conclusion that we really needed new boards. The problems were severe enough that we had neither the time nor the materials in-house to repair our damaged boards.

At this point it was Wednesday night, and we really wanted to get Impulse running by Friday. We were swiftly running out of time. In desperation, I reached out to my contact at Linear Technology to see if he could secure new boards for us at such short notice. He called me up Thursday morning telling me that he had the boards, and I could come and get them. I drove down from Berkeley to Linear’s headquarters, picked up the replacement boards, drove back to Berkeley, and installed the brand new boards in our car. A few short hours later, we were once again able to monitor and balance all of our battery cells. Thanks to the great people at Linear, our battery system is operational and working better than ever before.

People’s Car and People’s University

CalSol drove down with Impulse to the Volkswagen Electronics Research Lab today to give an end-of-year presentation on what we have learned, how much we have grown, how far we have come, and where we are heading next.  We’d like to thank everyone at the ERL for being there, supporting us, and inspiring us to dream big.  Additionally, we’d like to give a special thanks to Matt Montgomery for handling all of the logistical details of today; it was an amazing  meeting and CalSol had a blast!  With that said, we look forward to the continuing collaboration between People’s Car and People’s University…and GO BEARS!
