@György-Farkas I’ve never shipped anything to Hungary, but this would be a small and light package. Seems like it shouldn’t cost too much to ship(?) I’ll send you a DM.
EDIT: Does this forum even have DMs? Please drop me an email to my first name at LimeChile.com
If my math is correct, $30 should be a pretty good deal, especially with free shipping to U.S. Happy to ship elsewhere if you pay.
I made a lot of "aspirational purchases" via Kickstarter over the past few years, thinking I'd get into IoT. I finally did start tinkering recently, but quickly realized I have way more stuff than I'll ever make use of, and that I don't have the knowledge nor patience to do things like get Omegas out of boot loops. 
I'm going to follow this project: http://www.ryanwright.com/ht/powerrise/ . Rather than use external AAA batteries to power the remote circuit board, can I just use the Omega2 (on a power dock)? And if so, do I need to put a resistor in there?
Thank you all for the input! I assumed I would get email notifications of responses, and didn't think to check back until now. Unfortunately, I definitely fried an Omega2+ ! Ha! Oops. All part of the learning process I guess.
Wiring n00b looking for advice. Any pointers in the right direction are much appreciated!
I have a 4.5v solenoid ( https://www.amazon.com/gp/product/B013DR655A ) and I also have a MOSFET (TO220 Type Package, 60V, 30 Amp). I bought these a long time ago based on something I read online and likely misunderstood.
What's the simplest way to run this? Can I use the 5v pin and be done? Or do I need to use a 3.3v, and use the MOSFET to boost the power?
In either case, would I need to get a diode to protect things?
