Ev the Electron at the 2019 ALS User Meeting

Eventually we will create a whole post about our first Kickstarter project: Ev's Synchrotron Adventure: An Electron's Story, but I wanted to share one highlight. We were invited to share our work at the 2019 ALS User Meeting on October 1–3, 2019 at the Advanced Light Source in Berkeley, CA. The scientists and staff there have been so supportive of this project and we are so appreciative!

Poster Slam - 1 min to share our "research"

Our booth was a little different--most presenters shared posters detailing scientific research made possible by the use of the light source, or were commercial booths with special accelerator-related materials and equipment. (Fun fact: one of Ev's co-authors, Sam - now a freshman at UC San Diego - won third place for his heat shield research with NASA Ames and Lawrence Berkeley National Labs. Check him out!)

Finally, the ALS User's Executive Committee made a little plaque for us--I mentioned that they are very supportive! 

Then, in December, our 2019 seventh grade class participated in writing their own scientific proposals and, through a modified proposal review process, four groups were chosen to go to the Advanced Light Source and scan their samples on Beamline 8.3.2. (If you want to read more about the genesis of this thus-far yearly trip, you can read our 2013 blog post.) Prior to the trip, I had the opportunity to read the latest draft of Ev's Synchrotron Adventure to my 12- and 13-year old students.  The results were.... mixed... though they did say it helped the science be more approachable! (The nice thing about adolescents is that they don't sugarcoat anything to spare your feelings. So, I know the compliments were earnest and the apathy was honest.) 😁

Tales of Many 3D printers #tbt

[post under construction]

Is there such a thing as too many 3D printers?  I contemplated this over the weekend, as Facebook "memories' reminded me that I purchased my Makerbot Replicator 1 exactly three years ago. Looking around my classroom, I realized I have owned 10 3D printers. So, on this anniversary of sorts, I present: Where are they now?

1 Original Printer bot

2. maker bot rep 1

3. Cube
Our first Cube performed great until a problem forced us to replace it. The replacement also worked well, at least until it caught fire.

4. Printerbot (donated to BHS)

5. Printerbot simple metal
Gifted by Printerbot before maker fair 2014, the kids abandoned it, and it now resides Sam.

6. Droplit
We got this as a kit that some Maker Club kids assembled. Unfortunately, the kids that put it together forgot to document the process, and it now sits in a corner. We plan to start repairs after Maker Faire, but until then, it will remain in it's corner, starring down on those who abandoned it.

7. Afinia
The Afinia is the most reliable printer we have used to date. The print quality good, but the rafts are hard to get off. It currently is suffering from a clogged extruder, and will be fixed soon.

8. maker bot rep 1
We got this one for 90$ at a maker clearance event brand new. It worked fine for a while, but there is currently

9. maker bot rep 1
This was also from the clearance event, and was also brand new.

10. Buko bot
We the Bukobot got to act as a more "kid friendly" printer (also because it could print upside down), but there is something wrong, and cannot move on the z axis, and will make grinding noises if attempted.
