Tutorial - Beginner's Guide to KiCad
about 5 months ago
When I migrated from Eagle to KiCad in 2013 I really missed those Sparkfun libraries - it’s good to see them making a comeback for this excellent open-source package. Thanks for the excellent tutorial too!

I see that Elektor in Germany is selling an updated version with 1920*1080 resolution. Does Sparkfun have any plans to stock this? https://www.elektor.com/pi-top-diy-laptop-kit-for-raspberry-pi-de

To efficiently read two documents side by side I find that 1920 is the minimum horizontal resolution to do the job. I wear prescription glasses and have no trouble seeing individual pixels. When I use Windows, font scaling is turned off. (I would not be using windows on this device!)
If this screen size/resolution works for other users, that’s great. I’m merely providing feedback on why I’m not buying one and what it would take to make me buy one. I’m certainly not unique in this opinion:

That’s a neat trick, but my goal is to take the pi-top on the road with me as very light laptop with great battery life. A bit like a DIY chromebook but still a “real” computer.
Thanks Chris, I might just do that. Thanks for the link!
If this ever gets updated with a 1920x1080 screen, I’m in.
If anyone knows of a suitable HD screen that will fit in this, please let me know!

The datasheet lists winemaking as one of its suggested applications, so I guess the answer is yes. Datasheet here: http://www.atlas-scientific.com/files/datasheets/_probe/DO_probe.pdf

I don’t want to start a flame ware here, but only three countries in the world haven’t officially adopted the metric system. I know Sparkfun is in the USA, but even American engineers use metric. Ounce-inches? An online search tells me it’s 2.42 newton-meters, in case anyone was wondering.
News - Where does the Pro Mini 5…

Um, I don’t think there was ever a “panic” about an impending ice age in the 1970s. Not among climate scientists at least.
In the 1970s there was a lot of discussion about ice ages and climate cycles. No informed source was sowing panic about an impending ice age. Even back in the 1970s we could do simple math, and we understood the time scales involved.
The sheer speed with which we are putting CO2 into the atmosphere is orders of magnitude different from the timescales of ice ages, which is part of the reason there is concern.
Note also that the idea of anthropogenic climate change due to CO2 is not new. I’d have to dig out the references, but this was being discussed 100+ years ago when scientists calculated net solar radiation over the globe as a whole.
I hope I’m not encouraging the trolls by feeding them.

Can anyone tell me maximum output voltage of this thing? Right now I’m using a TL499a to stepup 6v to about 26v at 10mA… would this chip be able to do the same job? I’ve looked thru the datasheet and the application note and I can’t find this info anywhere, what am I missing?
No public wish lists :(
