..workbench chatter

Melissa and I have been out of town for a little while. I was hoping to blog on the road but it just didn’t happen. That midwest weather is in a nasty way; I don’t miss winter weather at all. So I have a little more work on two posts I’m working on but I wanted to update the blog for if no one else myself. I need a little brain purge… I have a lot of stuff to work on.

When I got home I had a dozen and a half packages or so from China. A ton of fun stuff.. most of it was for the little robot I’m working on. I also brought back a ton of stuff from my house (in a storage room) that I have left behind.

On our travel across county we stopped by our house in South Dakota and picked up a bunch of our items in storage. I brought back a few boxes of miscellaneous electronics including a lot of older projects I built years ago.

Look at that pile of stuff! A part of one box of old projects I built. Only a few more boxes to go! I got excited about a bunch of copper clad board that turned out to be really cheap; lame!

While out of town a mailbox and a half of sensors arrived from China (eBay)! Time to get building.

Sensors! I guess it’s time to get building. I’m not sure what I’ll use.. I’ll just tinker around until I find what I like.

So I've etched PCBs by sharpie.. I've used the tape and stencils... even photo etching which provided decent results. With all the talk in the IRC chat room I finally decided I needed to try out this professionally built business.

“My first PCB”… that I didn’t etch myself. The white stencil isn’t right but I knew it would be that way and I was in a hurry to get it on the way. It looks great. I haven’t checked out all the circuit paths but everything looks good. I decided on OSH Park because he is local-ish and seems like a decent guy. The preview feature is nice on his site.. and the price was reasonable. (yeah, I know.. it’s just a proto-board.. I didn’t build it for any specific reason).

Check out the motor controller heatsink!

Finally I got these tiny heat sinks I ordered .. (look at the motor controller on the robot platform). The motor controller is the same one I used for my Roomba Sumobot… it got very hot a few times I’m hoping to avoid those issues this time around with this heatsink that comes with some sticky stuff that hopefully conducts heat well. It was a 10 pack.. pretty cheap.

That’s it! I need to get along with my other posts…next week I’m out-of-town for training; maybe I’ll get something done then? 🙂
