How about printing a circuit on a balloon? Flexible and new thinking about design as the circuit is growing and expanding while inflating it. You could make small blimps in notime with small motors and...

Yes! I want to know if this is an option as well.Also, is it possible to: 1. Remove ATmega328 from an existing UNO board 2. Stick in a NON-BOOTLOADED ATmega328 into the UNO board 3. Burn a bootloader...

JST battery connectors are good… but flexible magnetic ones that can safely* be added to some of the smaller lipos would be nice. Hit-up the link for an example in micro / Uberlite RC...

Perhaps he was accidentally restricting the airflow with an aerosol'ed accelerant, like propane? :)

I’d avoid these for applications with sensitive inputs. I totally agree with above comments on output load balancing – I fried TWO Raspberry Pi Model Bs in the span of 30 minutes with this power supply...

Great stuff! Thank you very much! It would be helpful to know a couple identities/sources: What kind of pump did you use? Is is a kind that can handle metal chips in the fluid stream? You didn’t...

Pretty sure the pump used is SFE’s 350 GPM water pump.

The regulator on these is a surface-mount linear regulator, which theoretically is good all the way up to 21 volts or so, as long as you stay within heat limits. These take very little power, and my...

This was one of the best ideas I could think of, but I’m late to the party. Just wanted to comment to agree that I think this would be a cool product for sparkfun. Put double sided tape on the back and...

Flexible keyboard. Use capactive plates, or spectra symbol’s force sensitive resistors. That way, there would be no non-flexible components. The keyboard could then be stuck to non-traditional or...

I work in a pipe fabrication shop, so the metal aspects of this project are quite familiar to me. One thing that surprised me is that you used a band saw and a mill to clean up your pieces after you...

Considering you could use it anywhere, it would be great for reminders. Developers could also use it as storage devices, to show data such as graphs or code, and possibly be able to upload “mini OS”’s...
