I love engineering pads

January 4, 2016

After having spilled coffee on one pad and actually finished the two others that generally live on my desk, I went to the pile of office supply paper and dug out an engineering notepad. I found this:

Making Embedded Systems Info Sheet

This is clearly a sketch for an information sheet from the podcast two years ago. So much has changed about the show (even its title) that this is a pretty funny little view into the beginnings of the show.

Of course, I wasn’t digging for an engineering pad purely for nostalgia. I wanted to sketch something out. And since I kept re-doing it until it almost looks good, I figure I should share it.

I wanted to know how the itty-bitty quadcopter’s motors worked. This is for the Cheerson CX-10, a quadcopter that is just a bit bigger than a quarter.

Throwing Boards Over Walls

August 23, 2015

In response to comments made on Embedded.fm episode 114 (Wild While Loops), an electrical engineering listener emailed us:

We all know that ‘throw it over the wall’ sucks as a business pattern. But it’s sometimes really hard not to; I’ve recently been under pressure to order those new boards already. Or I’ve flat-out overlooked something. Or I misunderstood how much testing the last guy had done. Or whatever. It’s hard.

We know we shouldn’t just throw and run, but it’s hard. Do you have any thoughts on how to persuade my boss that stronger reviews, and getting the embedded software people in on them, are a good idea?

I recognize that “throwing over the wall” between hardware and software is somewhat inevitable, especially as HW and SW sometimes have different schedules. The difficulty comes in when there is also animosity: the EE says the problem is software, the SW says it is hardware; no one works on it because it is clearly not their bug (or works on it resentfully). I remember those days and am very glad I grew out of it.

But how to persuade your boss more reviews (and possibly earlier reviews) are worthwhile? If your boss is a promoted engineer, data might help. How many issues were found and by whom? (That person could be part of the reviews.) How many hours do the SW folks say were lost to HW difficulties (that includes schematics they didn’t understand)? How much will a board respin cost if a problem isn’t identified until a quarter of the way through the software schedule? (Even better: how much did the last respin cost in terms of money and time lost?)

You might also pitch better reviews as cross training: should you win the lottery and go on a bender, a cross trained embedded software person might be able to babysit your work for a couple weeks until you sober up or another EE is hired. (We used to say “get hit by a bus” until my EE actually did; now I try for more positive scenarios.)

I am quite thankful that HP believed in cross training. I know the EEs didn’t get a lot from my review of their schematics (“Can you rename this net because I don’t understand your vernacular?”) but I sure did. It made me more effective in my firmware job because I knew what their plan was. It allowed me to debug with an oscilloscope by myself because I understood the schematic before I had to use it (before I was deep into “there is a problem!!!” mindset). Plus, I could ask for the test points I needed instead of cursing the lack of available signals.

And, of course, it is hard. Not only is the work hard, the boards and code are personal expressions of our brains making criticism difficult to accept gracefully. And engineers often neglect to turn on their niceness modules. And schedules are brutal. There is no time for reviews and it is hard to expose ourselves to the angst.

But you do the best you can and try to do work you are proud of, sometimes fighting the right battles, other times tilting at windmills because part of you knows it is important even when others can’t see it.

Hey, look, a rousing speech to close on.

Intro to podcast 2

July 23, 2015

The podcast has changed some and I need a new intro to send to potential guests. 

Thanks for forwarding on this message to people who might be good candidates for being a guest on our podcast.

Embedded.fm is the weekly show for people who love building gadgets. Our guests include makers, entrepreneurs, educators, and normal, traditional engineers. We talk about the how, why, and what of engineering, usually devices.

The audience consists mostly of hardware and software engineers. The show is in iTunes and Stitcher or you can get it directly from embedded.fm.

I’m interested in talking to people about their systems: how does it work? how did you develop it?  how did you fund it? what’s your favorite tool? did you set up a manufacturing line and where? how do you teach people to do this? what draws you to engineering?

Recording takes about 90 minutes, it isn’t live so mistakes can be removed, and you shouldn’t have to prep much since I want to talk to you about something you already know. I prefer to record in our home studio near San Jose and Campbell, California but we can do recording via the Internet (Skype).

While this is sort of advertising for for my book and our consulting company, we don’t really discuss them (except to say, yep, still there). I do this mostly because I like to talk to interesting people about their jobs…  and maybe to have a few more women’s voices talking about technology (but not necessarily about being women-in-tech). That isn’t to say it is only women guests, we are happy to talk to just about anyone who is enthusiastic about science, technology, engineering, and math.

Interested? Know someone who might be interested? Please send a message.

Thank you!

April Fool’s Joke

April 8, 2015

Over a thousand people have downloaded an episode of the embedded.fm where I interview our cat

At least three people listened to the whole thing, probably more. It was not our usual hour, only about 20 minutes but still I interviewed our cat. Chris piped up occasionally with the most hilarious additions. But I didn’t really expect other people to listen to the whole thing. I did it for my own amusement. I felt a bit guilty as it caused Chris lots of work (editing it was really tough! And yes, that was our cat though there were multiple recording sessions).

This is the first time I’ve ever participated in April Fools day. It has always been something I avoided or looked on with annoyed amusement (ThinkGeek, though, that is pure amusement).

There is a community to having done a prank like this. 

I found the episode really funny to plan, to do, and to listen to. It worked for me and even thinking about it now makes me want to giggle.

But a joke that is shared? It is much better.

Shameless Self Promotion

March 19, 2015

I recently read Amanda Palmer’s The Art of Asking. It was a good book but I feel like I should be able to use the information instead of be vaguely amused, somewhat uncomfortable with the anecdotes.

Once again, I started a blog post with a plan and then totally lost the thread by the second sentence. Writing is hard. This blog is where I practice-write. I know it is public so it isn’t my absolute worst attempts (the drafts area is a scary place) but it isn’t an attempt to be professional.

On the other hand, Chris and I have been trying to be professional with writing for Element 14. We have a blog called The Linker that is loosely related to the people was talk to on the Embedded.fm podcast. Readers don’t have to listen to the podcast, the idea is we start from some topic we discuss and explore it further.

In Solving a Different Problem, Chris talked about how a guest said he wanted to explore a business problem instead of a technical one, how that’s neat and different from most engineers.

In How to Win the Hackaday Prize (and Other Design Challenges), I mug about being a judge for the Hackaday Prize (again!).

In Make Anything, Chris starts to explore the idea of how open source hardware is changing the industry.

In the next one, I’ll be talking about how applications matter to me and why that makes working on open source tools difficult, which makes me appreciate them more.

So yeah, I’ve been quiet here because I’ve been writing over there. We are getting paid for that which is nice. Though we’ve both been so angsty over, the material the cost/benefit is not going well. I think after we’ve got a half dozen finished, it will flow more easily. I hope, I hope.

I suspect that will happen around the time we hit 100 podcast episodes. One hundred. That is just crazy. We are still having a good time, still enjoying talking with people and hearing from listeners.

I’ve never been much of a joiner. I’m truly an introvert: I’d rather be by myself (or with Christopher) almost all the time. Without an external impetus and a fair amount of effort, I wouldn’t meet people. But after almost-100 episodes, I feel a lot more connected to the industry and to the the community than I’ve ever felt.

Chris and I have talked about ways to publicize the podcast. I got stickers (ok, the stickers crack me up but they seemed like a decent giveaway for people who want to know the show name when I’m at conferences).

I was looking into going to more conferences. However, Chris pointed out that conference attendees and podcast listeners may not overlap. That prompted me to ask if I could go on The Engineering Commons, they said yes and I did. It was fun, I should see if there are others.

As for conferences, I am going to and speaking at  Solid in June on inertial sensors and ESC-SV in July on making. I’m already nervous.

Other than that, I’ve been working a lot. I have two projects that are currently in the “omg, I broke everything” stage. One of them will be finished in the next week (fix then finish white paper). The other will get fixed and then I can start the fun parts.  (The third one really seems to be in production so it is finished… or would be if they’d pay me. Sigh.)

A week or two ago, a friend asked how things were going. I burbled on about work and the podcast and Chris. Then she asked about non-work stuff, how is that going?

I was couldn’t come up with anything. I mean, I read many books and watch tv but didn’t think we’d have any commonality there. I have some new ipad games I find amusing but those are mental cupcakes so I’m a bit embarrassed about them. House and garden need attention but who wants to hear about my plans for new closet doors and mulch? And my exercise program is going well but I can’t really imagine discussing it. It made me feel a bit one dimensional.

I know that is silly.

Well, if this was a professional piece, I’d wrap it all up and have some grandiloquent point at the end. Yeah, you can imagine that for yourself while I go make lunch
