Step 5: Measure and Cut the Wire

Use the planning sheet to determine what connection to make.

Before cutting the wire, strip 2mm of insulation from the end.

Line up the wire on the perfboard so that it extends from one connection contact to the other to get a sense of how much wire you'll need.

Add about 5mm extra length, cut the wire and strip off 2mm of insulation.

You now have a wire with 2mm stripped off both ends.

<p>Really good instructable. Very nice construction. </p><p>I actually found this because I was looking to see if there's a &quot;standard&quot; way to use perf-board.</p><p>Couple of things spring to mind.</p><p>I've been using wire taken out of solid core cat5 cable for this. It's an incredibly bad idea, the insulation shrinks back when soldered and melts through when the wire gets hot! So if anyone was thinking of using it, don't!</p><p>I've used Vero-wire for this in the past, which works really well. Much easier than having to strip individual wires. You get a special wiring pen which you thread the wire through. </p><p>I think the Vero wire is the same as solderable magnet wire, and I'm about to try building a prototype on perf-board using some from an old signal tranformer. Wish me luck!</p>
<p>Thanks for the printouts big help.</p>
<p>Broken link http://nscadesign.ca/mleblanc/</p>
Thank you very much for letting me know... I've repaired the link.
<p>Cool, Needed a way of making my own boards without any etching, Thanks for the </p><p>ible! </p>
<p>Wanted to say thanks. I've been working on and off with perf boards for some time, as well as boards that are analogs for breadboards, and the perfboards (similar to those described here) have been giving me headaches, as I'm &quot;sure&quot; there is a better way to build with them than what I've been doing. This looks like it. I'll have to start looking for the wire, and I may use forceps rather than tweezers, but I have pretty much everything else already, so it's worth a go I think. So, Thank you.</p>
<p>You're welcome. You can buy the wire at dx.com or ebay.</p>
<p>Useful stuff, thanks. Your list states 8mm solder, should read 0.8mm!</p>
<p>Great writeup! I'm just getting started with building circuits, and I found this very helpful. However, the planning sheet is a bit confusing. The numbers and letters on the sheet correspond to the letters and numbers on the front of the board, so rather than just being able to fill in the holes that correspond to your setup, you have to count backward from opposite end on the sheet. It would be more helpful if the numbers were inverted on the sheet, so you could just look at where your parts are plugged in, and fill in the corresponding inverted holes. Your description was very clear and useful though.</p>
very interested in knowing what you used, how you programmed this, and yeah... this just ENTIRELY interests me, aside from what you're actually trying to show here.... no concerned over the solder technique, just interested in how you built that thing, and got it programmed?!<br><br>I'm new to programming electronics, however no noob to programming. I design web sites, write scripts, and can code programs in C#, and C++. I've wanted to get my feet wet on a project like this, and you're seems just perfectly simple, yet challenging enough for me to be interested in doing it. (Don't just want to make a board that will blink lights in a predefined patter, you're flow (Amerage or whatever it measured) meter is awsome!
nice technic..
Why not just..... solder? It's not exactly difficult, nor does it look like it's much more work than this is.
I've been doing much the same, except that I use a wire-wrap pen to connect the wire to the post, prior to soldering.&nbsp; The manual wire-wrap tools don't make as tight a connection as a gun, but then, you can't really get a tight connection unless you're using wire-wrap sockets with their special sharp-cornered pins.<br /> <br /> Which is, of course, why we're soldering.<br />
