The oven build was surprisingly timeconsuming, yeah.
Re: reflowing both sides... There is special glue you can get to hold parts down. If you manage to make all the parts on the second side the same thickness, of course (like put all your resistors on the back) you can do the bottom first, then flip it over and put paste and parts on the other side, and you don't need glue because the parts have nowhere to go. When possible, avoid having to have parts on both sides (you'll notice that in commercial products, they will put all the parts on one side where possible)
Espruino is a JavaScript interpreter for low-power Microcontrollers. This site is both a support community for Espruino and a place to share what you are working on.
