High-­school science teachers can radically reduce the cost of building up science labs while giving students opportunities to engage in genuine design processes by introducing them to open­-source hardware. A vast collection of free and pre­-designed low-­cost scientific tools are available, many of which can be printed on a open­-source 3­D printer, including the printer itself. Not only can students benefit from access to research grade equipment, there are ample opportunities for students to build on, improve, and customize scientific tools as part of their curriculum. In this way the number and value of the open­-source hardware designs can expand with student effort, enabling a powerful motivating factor for science education.

Isn’t 3V really low for a lipo? I’ve always heard that they should never be discharged below 3.5v. I’m guessing that you will be throwing…
Screw ASCII! Mac Roman 4 life!!! Or 16 bit Unicode… that’s good too…
Done. I also added notes to differentiate the BQ27441-G1 link from the BQ24075, as well.
How about a link for the datasheet for the “fuel gauge” (the BQ27441-G1) chip on the “Babysitter” page? Some may want to use this with…
Hi Nate. I’m coming into this a little late, but it was good to see all the different insights to this (I think very difficult) problem from…
oh holy molly… There is much more to fuses than the voltage and current ratings. And if you feel the need to play with the AC mains side…
Right you are – should be fixed now, thanks!
Thanks! Looks pretty good. I’ve upvoted this and will include this in the batch to test.
I welcome anything that will help people learn but to enter it has to be a functional program. If you can post your mathematical approach…
