Подставки из печатных плат. Как я сделал гиковый подарок, который не хотелось заказывать с Amazon

Уже пару лет в моей корзине на Amazon лежал PCB-coaster — подстаканник в виде настоящей печатной платы. По отзывам, такие штуки охотно дарят на Новый год, дни рождения и корпоративы своим друзьям, близким и коллегам-инженерам. Сами айтишники и технари тоже берут их себе — на столе оказывается реальная плата, на которую можно поставить стакан. Выглядит круто, и в русскоязычном сегменте ничего похожего я не находил. Поэтому, решил сделать такой PCB-coaster сам. Теперь помимо набора для пайки «Мем Кот» в моём ассортименте появились подставки под стакан в виде печатной платы в пяти цветах.

FR-4: материал, который у всех на слуху, но мало кто в него всматривался

Когда речь заходит о печатных платах, FR-4 упоминают чуть ли не в каждом втором разговоре. Это стандарт, основа, база, с которой начинается почти любая электроника. Но за привычным названием скрывается гораздо больше, чем просто "стеклотекстолит". И если копнуть чуть глубже, оказывается, что FR-4 - это целая вселенная материалов со своими нюансами, подводными камнями и неочевидными особенностями.

@iyalei Hey, I finally tried the #FR4 build plate on my new #3dprinter today and it works really well!
Bottom surface looks great (like on glass) and it holds onto PETG & PLA nicely. Had to wait a long time (under around 40°C for PLA) to release the part without bending the plate.
I will try ASA filament next.
