Lineage and the Nobility of a Trade
My dad passed away on June 14th at the age of 90. He was a civil engineer and a building contractor. He was an engineer in the Air Force during the Korean War, building runways. His father, my granddad, was a talented jack-of-all-trades and a clever, whimsical inventor (he made himself a pair of convertible pants and a shirt several decades before the concept was patented). They both instilled in me, from the earliest age, the do-it-yourself ethos. When I was 5, I almost electrocuted myself when I tried to take the kitchen toaster apart with my Handy Andy tool set to find out how it worked – while it was still plugged in!
Here’s something I wrote in my first Tips book (which was dedicated to dad and granddad) about watching my dad seemingly effortlessly build things when I was a kid:
One of my early memories was being with my dad while he worked. I remember riding in a Gradall Excavator with him when I was a wee one. I thought my dad was basically the coolest guy on Earth because he could confidently pilot such an impressive, intimidating machine. As a pre-teen, I remember watching him swing a hammer while he was adding some rooms to the basement of our home (which he’d also built) and realizing how regular and perfect he was with his swing. It usually took him the same number of strikes each time to drive and countersink a nail – one swing to set the nail, one to drive it most of the way in, and a final whack to counter-sink it. I don’t remember exactly how old I was, but it was probably the first time that I instinctively understood the nobility (and the efficiency) of perfecting a trade. If you do something enough, you get impressively good at it.
Tools are an extension of our bodies, our intentions. Like specialized “end effectors” on a robot, they instantly give us special abilities; superpowers. Combine the right tools, the right materials, and the proper know-how, and human beings create worlds. Tools are the physical interface between our dreams, our imagination, and their real-world realization. But our tools are not only powerful extensions of ourselves, they also contain stories (see above).
My dad (and my granddad) taught me about both the power of tools and the power of storytelling. Little did they, or I, know when I was growing up that my job would end up combining these two powers.
Knurled Knob Generator
Who doesn’t love a handsome and grippy knurled knob? This OpenSCAD script on Thingiverse allows you to generate knurled knobs of various sizes that slide over bolt heads. The script requires the OpenSCAD compiler to generate the 3D models.
Using Syringes to Clean Out 3DP Resin Vats
Back in January, I wrote about Daniel Herrero‘s “hack” of using a peristaltic pump to clean out his resin vat for his 3D printer. And then, based on comments to his post, he got a better idea: using large syringes to suck out the remaining resin. He experimented and determined that a 150ml syringe works best. Once again, YouTube comments to the rescue. He complains in the video about the hard plastic syringe head scratching his FEP film at the bottom of his vat. Commenters suggested adding a short bit of rubber tubing to the tip of the syringe. He also mentions the resin scraper that comes with printers scratching his FEP and viewers remind him that a silicone plastic spatula (I got mine from the dollar store) won’t scratch the film.
Do Different Formulations of Motor Oil from the Same Brand Really Behave Differently?
Todd at Project Farmwanted to know if different formulations of oil from the same brand (Penzoil) perform differently, and is the high-end oil all that different from the cheapest one? The formulations tested were Pennzoil Synthetic Blend, Full Synthetic, Platinum, and Ultra Platinum. He sent the oils out to a lab for analysis and also tested them for evaporative loss, lubricity or film strength, and cold oil flow both new oil and after exposure to heat. Additionally, in a final test, Pennzoil Ultra Platinum was exposed to 10% gasoline and another sample to antifreeze to test the impact it had on lubricity and oil performance. Bottom line? This looks like a “you get what you pay for” result. The most expensive of the lot, Ultra Platinum ($28 on Amazon at time of test, $14.22 currently), definitely performed the best. That’s actually lower in price than the cheapest one at time of testing (Synthetic Blend, at $17). And, if you buy 6 quarts on Amazon, the Ultra Platinum blend is only $8.60/qt.
Fantastic Free Class for Learning Arduino
Via the always-informative Maker Update comes word of this really wonderful series of beginner educational videos on the hardware, development environment, and code used for the ubiquitous Arduino microcontroller. If you’re interested in getting into Arduino, there is no better gateway.
TOYS! Liquid Chrome Markers
I recently saw Adam Savage use these chrome markers in a video where he was weathering a prop that he’d built (the motion tracker from Aliens). I immediately bought a set and man do I love them. If you have a need to faux chrome anything…
FrogPod is Now on Kickstarter
I’ve been a big fan of Thomas Baisch‘s Instagram page, InfiniteCraftsman, for a while now. He posts one innovative shop solution after another, most of them 3D printed. One of his most brilliant creations is the FrogPod, a flexible, magnetized three-legged camera mount that you can slap onto metal surfaces. He recently launched a Kickstarter to raise an army of FrogPod users.

Cool tools really work.
A cool tool can be any book, gadget, software, video, map, hardware, material, or website that is tried and true. All reviews on this site are written by readers who have actually used the tool and others like it. Items can be either old or new as long as they are wonderful. We post things we like and ignore the rest. Suggestions for tools much better than what is recommended here are always wanted.
This two-sided page contains the wisdom of an entire book on how to write better. Nay, it distills an entire shelf of the world’s greatest writing manuals (and I have them all). After 30 years as both a writer and editor I can’t think of much I would add to these 50 short tips. This PDF is now my favorite guide to writing well. You can print it out for free. If you want its pithy reminders fleshed out with more examples, see the book form, or the website. But the free tip sheet itself — one paper printed both sides — rewards a quick review anytime you get down to serious writing.. – KK
There’s an emerging new media I use more and more: an online summary of a conference. Known as liveblogging, it presents a synopsis of each presentation, talk-by-talk, in nearly real time. This saves you time and money traveling to distant cities, and suffering through introductions and equipment failures. At its best, reading the liveblog can be better than attending the talk. All the chaff has been winnowed, and almost every talk captured. (Most conference attendees don’t even get to every talk.) Video recordings of conferences are becoming more popular, but a good liveblog is much quicker to scan and digest. But at its worse, a liveblog will offer little more than snarky comments about the speaker.
At the creation end, you need some skills to separate the best from the worst. Ethan Zuckerman, of Geek Corp, is one of the best conference bloggers alive. He teamed up with Bruno Giussani, another star liveblogger, to produce this free short 6-page PDF booklet on how to blog a conference with effectiveness. When you blog a conference it forces you to pay attention. My first book Out of Control began as an online blog of every talk at the first Artificial Life Conference (although no one called it blogging in 1987). The requisite focus of summarizing each talk clarified many ideas for me, and the response to the “blog” of the conference encouraged me to write a book. Other livebloggers find the same. They listen harder, and remember more.
Get good at this and you have a free pass to many high-priced conferences. Organizers are increasingly looking for first-rate livebloggers to generate press and future attendees. Or, like Ethan you can generate your own audience who follow you because your liveblogging skills. – KK
It’s relatively easy to blog good and great speakers: They follow a narrative path through their talks and speak at a pace the audience can understand. It’s harder to blog inexperienced speakers(because they may be too technical, confusing, fast, etc.) and multispeaker panels (because the discussion can take many different unstructured turns). But you don’t need to transcribe the whole talk, you need to capture the gist of it. A 20-minutes talk can often be summarized in a 20-lines post.
Always remember that what you’re writing will be read by people who weren’t in the room, so they haven’t seen the slides, the video, or the gesture. Hence, you have to compensate for the lack of context. Don’t be afraid to create a narrative by saying “He shows a slide with data on …” or “She walks on stage carrying a big suitcase” or “He shows a YouTube video” etc. And if the speaker shows a YouTube video, or a picture, remember that you’re online: Open another browser window, go to YouTube, find that video, and link to it; or go to the speaker’s website, find that picture or another similar or related item, and link to it (or republish the picture within your post). Yes, this requires effective multitasking. It’s at the root of conference blogging.
Conferences usually give out a program ahead of time. Use it to prepare for blogging: Do a quick Google search for each speaker, and save (in the same text file) links to their sites, blogs, and the institutions they’re affiliated with; write a one-or-two-sentences “biography” for each; and for the speakers you’ve never heard of, try to get a general sense of who they are and what they do. To write the mini-biography, use also the speaker information distributed by the conference organizers (booklet, website, etc.). For the key speakers, save a picture on your laptop (from their websites) and pre-format it for Web use, in case you will need it. If you prepare sufficiently, you’ve got the first paragraph of each post almost written ahead of time.
This is the best thesaurus there is. It supplies more synonyms, analogs, parallels, equivalents and comparable words in English than any other source, online or off. No other thesaurus comes near to it for completeness or breadth. Compiled in dictionary form, like the one in your word processors, there’s no index or cross-referencing. Just look up a word, any word, and it proceeds to overwhelm you with alternative choices (a total of 1.5 million synonyms are presented in 1,361 pages), including short phrases and only mildly related words. Rather than being a problem of imprecision, the Finder’s broad inclusiveness prods your imagination and prompts your recall.
Its single downside, however, is a major frustration: it is not available digitally, in a form compatible to the way most people write these days. It should live on your computer in a pull-down option, or plug-in for Word or the like. I’m totally baffled why it is not. As it is, it’s a huge fat book — a great book! — sitting within arm’s reach when I write, but not near enough for the power that it offers. – KK
