This past weekend I stopped into HGR, the local industrial surplus company in Northeast Cleveland. This place has industrial equipment from all over Ohio, unfortunately from plants closing down. Check out the pictures of all the machinery for sale…it’s enough to build one HELL of a workshop (and even a great new workbench!).

This Place is Monstrous

OK, I really would love a robot

The Roof Could Use Some Work

Aside from the 555 contest I mentioned in my last post, my February was spent building the workbench I drew in Google Sketchup. It was built partially for The Amp Hour, partially for circuits I plan on building and showing off on here and partially for my new business, Analog Life, LLC.

So for today’s show and tell, I’ll premier the first video ever with me in it on YouTube:

I also had a couple snapshots of the bench in progress:

I’m guessing if you follow me at all on Twitter or Facebook or just about anywhere else on the internet (I’m not too hard to find), you might know about the 555 contest. I have been talking about it quite a bit on various channels, all except here.

So I thought I’d discuss some of the aspects I might not discuss on other forums because they wouldn’t be relevant. But since this site is basically about me and my interests…well I get to write whatever I want! Sweet!

After talking about my planned bench on Episode 26 of The Amp Hour, I thought it’d be fun to animate the finished versions of my plans (or at least where I’m happy with for now). I know Dave likes making fun of me, but the implications of such free and powerful tools cannot be understated. Even 10 years ago, CAD programs were inaccessible to the layman. Now, a very simple and intuitive program like Google Sketchup is letting someone like me design something like this. Amazing. It’s a subtle message for engineers to keep increasing their values and their skills over the years, as skills that were once coveted become more mainstream and commoditized.

Hey Folks!

Because my brain decided I didn’t have enough going on already (and a healthy dose of thinking “wow, that’s a good idea” when Cherish mentioned it to me), I’ve started EngineerBlogs.org with a couple other engineer bloggers! I’ve already mentioned it on Twitter, but I thought I should write about it here as well.

The lineup right now is me, Cherish, Fluxor and FrauTech.  But we’re looking for more! If you’re interested, check out the “Write For Us” page on the site and fill out the form there. We have some requirements, but if you’re a good writer and have been doing it for a little while, we’d love to hear from you.

Well,  a lot of places.

But not around here too much. And when I’ve been here, it hasn’t been the most in-depth writing I’ve ever done (except my unusually thought out post comparing engineers to a fictional character, check that out if you haven’t, not many people noticed it). I can’t say I will be writing again full time in the near future, but maybe in the future after that. So here’s a quick rundown of where I’ve been and what I’ve been doing if you don’t already know:

I’m working on a new switcher design and need to be able to test the total current coming out of a boost converter. Here’s what I’m looking at:

• 0-60V rails (out of the boost converter)
• 0-350 mA
• No access to the load that will eventually be connected to the switcher

So what do I need? I need something that can sink current and dissipate any heat that will be generated. If the load is dropping the entire voltage at the top current, that will be:

I’m finally starting to get it.

Apparently in the past the design work I’ve been doing is too slow. It’s too methodical, I have too much time to question my decisions. Well not anymore.

I’ve been working on a time sensitive project recently (sensitive enough that I feel bad writing this post at 9 pm on a  Saturday) and I’ve finally started to understand the reason the part vendors come to talk to me about power module this and fast design that. They come in with these nearly-done solutions and try pushing them on me, only to hear me say something like,  “Wow, I’d never use that”. I mean, where is the fun in using a power switcher that is damn near complete?

“Wha?”

That’s what you said when you read the title, isn’t it? That’s probably what I would have said. You said that for one of two reasons:

1. You’ve never watched Firefly.
2. You’ve watched Firefly and you just don’t get it yet.

The second is more excusable than the first. If you’ve never watched Firefly, I highly suggest going to do that right now. It’s 14 episodes (one season) and a feature length film. It’s a great show that was unfortunately cancelled after one season.

Over on The Amp Hour, I’ve been known to call ham radio operators, “The Rock Stars of Analog“. This is meant for the ones that are out there making their circuits using the dead bug method or otherwise. Jason Milldrum from NT7s.com has confirmed this belief with a picture in his latest posting about his RF kit making business:

I mean would you LOOK at that thing??? It’s awesome! Plus it transmits radio signals, so it’s just that much more magical. I know the theory behind RF, but I still geek out whenever I think about radio stuff. Anyway, thanks to Jason for posting the picture on his site and on Flickr. Check out his blog for more info as it comes available!
