If I need something quickly, cant wait for PCB, but also it does have certain physical dimension requirements,<br class="">then I do get really "boring" and do "plan" perfboard - "what is the fun in that" someone asked - indeed, what is the fun in that sort of tedious, repetitive work alltogether?<br class="">Better make it as short as, and least error prone possible. It's so much easier to reason about misbehavior of a circuit if it actually matches what you have drawn - at least from the obvious (not parasitic) components and their supposed connections.<br class="">While it's perhaps reasonabnly unlikely to make mistakes if you have all the space in the world and basically solder together the circuit as-is-drawn on some big ass perfboard, also leaving lots of room for adding more stuff to experiment,<br class="">as things get more crowded and less intuitively placed, I found the following to be helpful:<br class=""><br class="">First of all, esp. for single-sided perfboard, I like to combine THT ICs with SMT 0805 passives, as you can often put them comfortably between legs and under the IC (on the bottom side of the board), that already saves a lot of space - and wiring effort.<br class="">There are also these, often green, plated-through double-sided perfboards - may reduce the insulated connections you have to make (which take longer due to the need for burning away the insulation / tinning), e.g. all GND with silver wire on the bottom, +V on the top side, or so, other nets with insulated wire, where unconnected crossings would be at least.<br class=""><br class="">Also, in the type of scenario where I would, if I could, prefer a small PCB, but don't want to wait,<br class="">I might already have a captured schematic in my chosen EDA software anyway - or if it's small, I'll just do it quickly.<br class="">Then convert to PCB, and usually don't route anything, or at best a few special traces to mark special preferences.<br class=""><br class="">I put that on my small-ish tablet with stylus support, that actually fits on my crowded soldering bench.<br class="">that also runs the EDA software. Then I:<br class=""><br class="">foreach non-GND-net:<br class=""> highlight net in PCB software<br class=""> connect all net points in circuit with insulated "coil wire", point-to-point<br class=""> hide net's ratlines (or color existing traces) to make visible what's still TODO - this shrinks more and more, and you can see the light at the end of the tunnel<br class=""><br class="">This, for me anyway, proved much less error prone than staring on a paper printout and comparing it with the current physical as-is schematic all the time (even when pencil checking traces ;) ).<br class="">Can basically do that half-asleep without making a mistake. (just make sure to display the bottom side mirrored appropriately :D)<br class=""><br class="">Then for the GND net I do the above, except I user silver coated copper wire, a bit sturdier, and wherever possible, do not cut, but bend around corners, using one long piece of wire across many connections, saving some work steps. The silver wire will be over all those coil wires, holding them in place a bit better, esp. longer ones, and make it less likely that you will rip off any connection by accidentally grabbing too hard anywhere.<br class=""><br class=""><br class="">- Steve<br class=""><br class=""><br class="">Am 31.10.2020 um 11:23 schrieb ShedSynth:<br class=""></div><blockquote cite="mid:067401d6af6f$e27cd1f0$a77675d0$@gmail.com" type="cite" style="font-family: Helvetica;
