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.

Do you think could I do the same with a 3v panel 2.5v 10F supercap to charge a 3.2v lifepo battery? Or do I need 2 supercaps? Thanks in…
Oh, so A+PRS is a no-go… Dang, we were so pumped for that. Missed it last year.
Please tell me you will bring back A+PRS!!!
That’s a good point and you nailed the reason why I didn’t test (and therefore mention) active terminators, because we don’t have an active…

Great article, but you missed the chance to talk about active terminators for I2C. Active terminators can clean up those slow I2C signals a…
I remember my first design involving I2C. I was adding to an existing design, and it ended up with two I2C buses, the first being designed…
