C.<p>About that BusBoard Prototype Systems SB4 board -- they're expensive. They're more than $6 each (Canadian) plus shipping from DigiKey. They're $10 each plus shipping from Mouser.</p><p>That's a lot for a hobbyist when you're experimenting, especially if you're making mistakes.</p><p>I looked around again recently, and couldn't find anything I liked at a reasonable price point.</p><p>So what does one do in this situation? Well, if you go Overkill 9000, you design your own prototyping perfboard and have a bunch manufactured for you! When you design your own, you can give it any features you like. So this one has:</p><p>18 x 36 (648 holes total)</p><p>It's two 18 x 18 sections, though I didn't have them scored for snapping.</p><p>A total of 6 horizontal busses in groups of 2, at the top and bottom plus one in the middle.</p><p>3 sets of 2 vertical busses within that space between horizontal bus sets, similarly edge - center - edge.</p><p>Then each row has a 6-hole pad on each side of the center 2 busses, which are spaced for IC or other standard 0.4" component layout.</p><p>Made of proper FR4 fiberglass. Good copper, good soldermask.</p><p>Silkscreened row and column IDs on both the front and back, at both the start and end of each row/column (and they match up with the back...).</p><p>And silkscreened boxes on the front showing the pad/buss pattern - no more flipping!</p><p>They arrived today and ... they're beautiful.</p><p>2/x</p><p><a href="https://mindly.social/tags/PCB" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>PCB</span></a> <a href="https://mindly.social/tags/CustomPCB" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>CustomPCB</span></a> <a href="https://mindly.social/tags/silkscreen" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>silkscreen</span></a> <a href="https://mindly.social/tags/overkill" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>overkill</span></a> <a href="https://mindly.social/tags/Overkill9000" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Overkill9000</span></a> <a href="https://mindly.social/tags/buss" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>buss</span></a> <a href="https://mindly.social/tags/busses" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>busses</span></a> <a href="https://mindly.social/tags/pads" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>pads</span></a> <a href="https://mindly.social/tags/components" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>components</span></a> <a href="https://mindly.social/tags/IC" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>IC</span></a> <a href="https://mindly.social/tags/DIP" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>DIP</span></a></p>
