Designing Electronics That Work

This is an interesting book. I&#x27;ve been in this space for years now and could easily see myself writing something like this, but I don&#x27;t think it would look like this book.<p>I really don&#x27;t like to see things like any sort of recommendation for use of n-propyl bromide. That shit&#x27;s neurotoxic. The people who can use it safely will already know about it, know someone who knows about it, or find it on their own. Anyone who finds out about nPB here should not be touching it.<p>Unfortunately, many of the parts of the book that I&#x27;ve scanned are like that. There&#x27;s a lot of prescription, not a lot of background&#x2F;theory&#x2F;underlying details, and no way to tell when the prescriptions are inapplicable or straight-up wrong. Which, often, they are: one of the hallmarks of deep experience is knowing when &quot;the rules&quot; are useful and when they&#x27;re not, but what we have here is mostly rules. That will get your product out the door, I guess, but it&#x27;s not going to level you up as an engineer, if that&#x27;s what you&#x27;re needing. Another example: stackups are discussed, but there&#x27;s no mention of slash sheets, which is how you get things done cheaply and correctly. Specifying Rogers material for anything but the nastiest designs is just going to get your pockets drained and your Asian fab annoyed because they have to special order that. If you need it, sure, you need it... but can you get away with something more universal?<p>And then there&#x27;s things like this: &quot;Most SMPS datasheets will advise you on what bead to use and where to put it&quot;. Hahahaha no they won&#x27;t. And if they will, there&#x27;s a decent chance they get it wrong. Ferrite beads are so useful and so much trouble that you can&#x27;t trust an IC datasheet to get it right, even if <i>they</i> want to do the same things <i>you</i> want to do. Which they might not!<p>If you&#x27;re a more junior engineer trying to level up, give this one a look instead: Analog SEEKrets: <a href="https:&#x2F;&#x2F;www.eevblog.com&#x2F;files&#x2F;seekPDF.pdf" rel="nofollow">https:&#x2F;&#x2F;www.eevblog.com&#x2F;files&#x2F;seekPDF.pdf</a>

I flagged this entry because it looks like a marketing stunt.<p>The description of the book was looking appealing, and I was amazed at the good spirit to have a free downloadable version.<p>So I opened a new tab for the free and paid versions, because I was curious to see the inside but interested to have a hard-copy.<p>But then, on one side you arrive on a page that says that the digital copy is &quot;sold out&quot;... lol... sold out. And on the other side, the hardcopy page says that it is not for sell anymore as a new version will arrive and here is a link to &quot;pre order&quot;. And the funniest is that this link to nostarch does not even work...

I&#x27;ve begun playing around with &quot;hardware design&quot; recently and it&#x27;s very humbling. I&#x27;ve been developing software for a long time, and I have a good amount of experience designing and making physical objects, both manually (well, with tools, but manually guided&#x2F;used) and via digital means (mostly FDM).<p>Making even a simple electronic device is a journey to say the least. The intersection of code and mechanism is a fascinating area to play in, but from PoC to Product, the amount of effort, expertise and iteration is hard to imagine until you try.<p>Thanks for sharing your experience, looking forward to leafing through the pdf for some valuable insights.

If you want your electronics to work:<p>1. Read the datasheets for everything and follow all restrictions, like on safe operating area (SOA), in regard to current and ambient temperature and so on. Use appropriate heat sinks.<p>2. Unless you have good reasons or confidence coming from somewhere, do not stray far from the example circuits in the datasheet. If they call for certain decoupling capacitors, have those. If something has a minimum and&#x2F;or maximum load impedance, be in that limit (same as point 1).<p>3. Do not design anything to depend on the performance of an individual part, in regard to some performance parameter that has lots of variance in mass production of those parts. This is particularly a problem for analog components; e.g. current gain of bipolar transistors and such. In simulation, play with variances in part values to see how sensitive it is; you can choose tolerances accordingly. Maybe some resistors need only 5%.<p>4. Good PCB layout and so on. Careful breadboard work. Proper soldering practices. Solid power supply circuits operating well within their capacity range. Proper grounding. Safety devices: fuses, diodes, etc.

Apparently the ebook has “sold out” so this is just marketing for the new paid ebook preorders.

I wonder if on the first page it says:<p>Hardware is a money pit so be sure to be motivated by passion more than profit.<p>I&#x27;m kidding, but only sort of.

It seems the hard copy is out of print, and they are sold out of the “free” digital downloads.

I would love to see a book called &quot;designing electronics for a person who has never touched electronics&quot;

I&#x27;ve been doing some analog PCB layouts for the first time recently, it&#x27;s the one thing I wish there were better resources on (going from schematic to layout). Even the best YouTube vids are mostly simple digital stuff with very few components.

The page contains a link that says &quot;If you want to get a copy, you can download a digital copy for free.&quot; Clicking this link either asks you to name a price (for something you haven&#x27;t yet had a chance to evaluate) or takes you to a page that either has no actual .PDF download link, or has hidden it well enough to turn it into a puzzle.<p>Either way, not an ideal first impression. Designing electronics that work is a lot like designing a web page that works: even if it doesn&#x27;t end up simple, it should almost always start out that way.

I would really like to purchase a hard copy. The hero picture of the book is enticing. Looks like it&#x27;s not available right now sadly.

I own a hard copy of the book. It&#x27;s very valuable as a survey to speed run getting over &quot;Peak of Mt Stupid&quot;, crossing &quot;Valley of Despair&quot;, and beginning the climb of the &quot;Slope of Enlightenment&quot;.

Nice work Hunter! I’m starting a hardware side project so I’ll definitely be giving the book a read. Hopefully it helps me avoid some of the common electronic pitfalls.

The web site says the digital copy us free, then links to another web site that says it is no longer free.<p>Scam?

Trying to buy a physical copy. It says &quot;This product is not currently for sale.&quot; Would love to buy this.

You knocked it out of the park with the cover! I&#x27;ll definitely be grabbing a physical copy because of that.

This looks great! Exactly the kind of practical knowledge that is hard to come by.

Maybe (2021) should be added to the title?

&quot;The Art of Electronics&quot; is the classic in this area.

&gt; To give you an example of the cost of getting full FCC approval, a company like UL will charge around $15,00-$20,000<p>I hate typos like these

Please do not use leadless parts. Please do not use parts smaller than they need to be. Please make your BOM perfect. Please make your silkscreen perfect. Thank you.

Wow, this looks very interesting and educational. Thanks!<p>Also, I&#x27;m certainly no designer, but I wonder if it hadn&#x27;t looked better if the title had been laid out like:<p><pre><code> Designing Electronics That Work </code></pre> rather than (as now):<p><pre><code> Designing Electronics That Work </code></pre> Is there any particular reason behind this (to me) off-balance design, like some kind of deeper connection with the content of the book? Or do I just lack taste and imagine things?<p>Edit: actually praise the effort, since it looks really cool.
