If you're making your own power cables you should grab one of the DIY pcbs out there that test all the wires on the ribbon cable after assembly. It's worth it to know any build issues aren't from a missaligned power cable. I test all my power cables now before first use.<div><br></div><div>Kylee</div><div><br><div><br></div><div><br><br>On Tuesday, January 3, 2017, Tim Ressel <<a href="mailto:timr@circuitabbey.com">timr@circuitabbey.com</a>> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">

<p>The diodes are a good idea even if you used a boxed connector.
They protect from mis-made power cables, which happens all too
often.</p>

<div>This is what I plan to use. Maybe my pin umbers are off. I
was going by the image linked below. Is pin 1 on the bottom
right in this image?</div>

<div>It seems like I should just not use it?</div>

<div>Resistor</div>
<div>Don't use it?</div>
<div><br>
</div>
<div>Ferrite Bead</div>
<div>Some people are telling me outside this list that ferrite
is more for digital stuff and that the capacitor should be
fine. If I don't use the ferrite then should I use a resistor
instead?</div>
<div><br>
</div>
<div>Capacitors</div>
<div>Only use the larger one (I use a 0.1uF bypass cap at each
IC anyway). Some say increase and some say decrease. In
non-modular stuff I usually use larger ones, so I am leaning
towards 22uF.</div>

<div>I wish that there was a standard for this so I knew what to
do :(</div>

</span>Some years ago, Tony Allgood mentioned that he had to
switch<br>
from 22 to 2.2 µF per rail because the surge current from
lots<br>
of 22 µF capacitors in parallel made certain Power-one
supplies<br>
misbehave on power-up. But that was with ferrite beads, not<br>
resistors.<br>
