No, bottom is still flat. The internal structure is a bit more fluffy and therefore a bit elastic. |

Here is one: PCB Cleaner spray (the usual isopropyl and ethanol mix) used to clean flux off your boards is excellent at removing hot glue from pretty much any surface. Just soak the blob of hot glue in the stuff, leave it sit for a few seconds than pry at it a bit while its still wet, the hot glue suddenly looses all adhesion and just falls off, but it doesn't seam to dissolve the hot glue at all so it does not make any mess. |

Oh, glue makes me think of another. You can remove dried PVA glues by soaking them in an alkaline solution. Water alone just very slowly wets them, an alkaline environment degrades them. A bit of washing soda (sodium carbonate) in water does the trick. The usual caveats about not doing this if water or alkali are going to damage the glued items applies, obviously. Taught to me by a guitar maker/repairer. |

When I was student, I used to recharge alkaline batteries. Still do this sometimes, though the capacity is poor. |

If you're long sighted, the watch makers trick of wearing two pairs of reading glasses, one in front of the other, means you can solder PTH and SMD parts, without the need of a stereo microscope. Depreciated mouse mats are an excellent source of neoprene sheeting for all kinds of DIY packing and mounting tasks. |
