C.The best part? My cost for manufacturing the boards and shipping them to me in Canada (from China), with all applicable duty and taxes included, brings them out to about $1 per board.I may try other designs at some point. But I can't see myself going back to the uber-expensive ones that are commercially available.I can't wait to try one of them!3/3<a href="https://mindly.social/tags/MakeDontBuy" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#MakeDontBuy</a> <a href="https://mindly.social/tags/design" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#design</a> <a href="https://mindly.social/tags/custom" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#custom</a> <a href="https://mindly.social/tags/maker" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#maker</a> <a href="https://mindly.social/tags/electronics" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#electronics</a> <a href="https://mindly.social/tags/experiment" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#experiment</a> <a href="https://mindly.social/tags/cheap" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#cheap</a>

C.When building electronics project for permanent use - i.e. after testing on a solderless breadboard - you normally go to a <a href="https://mindly.social/tags/soldered" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#soldered</a> perforated board of some type as a <a href="https://mindly.social/tags/prototype" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#prototype</a>, or even for very-low-volume production.There are different types of boards. I dislike "matrix" boards, which are just isolated pads on a grid, i.e. there are no connections between any of them. Some people swear by these; I swear at them.I prefer protoboards that have multiple holes per pad (so you can connect multiple component leads without having to add an explicit wire jumper). If they've also got <a href="https://mindly.social/tags/busses" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#busses</a> - sets of pads that run the whole length or width of the board - so much the better!Some are <a href="https://mindly.social/tags/crap" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#crap</a>: laminated paper PCBs where the pads lift off the board if you even try to desolder something you added. Row/column labels missing, or (like I found with some recently) that don't line up between the front and back of the board 😆 , or most egregiously, they don't actually show the pad pattern on the front of the board, so you have to keep flipping it to check your parts are correctly placed. One example below.I have some from "BusBoard Prototype Systems" that I like. The SB4 is a 38 x 24 (912 hole) board that is <a href="https://mindly.social/tags/snappable" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#snappable</a> into quarters. Two of the quarters have rows that are 4-hole, 2-hole, 4-hole. The other two are 5 2-hole pads. Both types have a single bus running along each of the 2 long sides.But ...1/x<a href="https://mindly.social/tags/electronics" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#electronics</a> <a href="https://mindly.social/tags/hobby" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#hobby</a> <a href="https://mindly.social/tags/ProtoBoard" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#ProtoBoard</a> <a href="https://mindly.social/tags/PerfBoard" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#PerfBoard</a> <a href="https://mindly.social/tags/MatrixBoard" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#MatrixBoard</a> <a href="https://mindly.social/tags/Chinesium" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Chinesium</a>
