		<description><![CDATA[I&#8217;ve finally gotten around to fabricating the first version of my CAN-based keypad board. This unit was designed to act as an input/display device for the security-esque features of my automation-integration system. This is revision 1a of the board, so it&#8217;s really a prototype version. The board provides the following resources: a 16 key input [&#8230;]]]></description>

		<description><![CDATA[I&#8217;ve been using surface mount components on my boards for a while now and using a syringe and needle to deposit solder paste has worked fairly well. But it&#8217;s a pain using that technique for fine-pitched components. I ran across https://www.oshstencils.com/ and decided it was time to try using a solder stencil.

		<description><![CDATA[In most of my past projects, I&#8217;ve been using basic linear regulator circuits for voltage regulation. That has worked fine up to this point, but now a couple of my projects are needing to use higher voltages for some components. A good example is my CNC machine, which uses 24v for the stepper motors. I [&#8230;]]]></description>
