I use it to pop popcorn, deep fry churros, pastries, etc. The cool thing is that we can reuse it unlimited time and it is still healthier than vegetable oil!

Nice project and nice tiles on the background too... :D

Did anybody try using transparency laser printer papers? This may avoid paper trails sticking to the board. It may also be useful because we can see if the solution is spread evenly. Anyone?

That sounds great, rachesv99! ;) Thank you!

Great project but how loud is it? It may need a power amplifier if we desire it to be loud since the bluetooth receiver is designed to be connected directly to an auxiliary input, so it may have just a pre-amp with few microwatts of potency, and the impedance gotta be observed when connecting the device's output to 4/8 ohms speakers or it'll distort.

@e5frog: You can correct the defective tracks using a permanent marker pen before treating the PCB. You can also design the entire PCB using this kind of pen - it may not come out neatly, but it works pretty well.

If you get the "negative" of one of those kid's stickers and use it as a template... remove all stickers (and give them to your kid saying "good job!"). Get what is left, cut the page to fit in the jar, peel it out carefully and stick it inside the jar. Paint its positives to get perfect shapes, such as stars, dots, etc.. after the paint is dry, just remove the sticker and bingo! Not sure how thick the paint gets, just be careful not to put too much overlaying the template, or it will get hard to remove it later on.

Goo Gone works great, but be careful not to spill it over a table with polyurethane or other finish... it'll ruin it badly!
