Cool Tools Show 128: Dan Ruderman
Our guest this week is Dan Ruderman. Dan is a physicist and technologist. He is faculty at the Ellison Institute for Transformative Medicine of USC, where he applies machine learning to individualized cancer treatment. Dan enjoys overseas travel, and picking up enough foreign language to never again order a plate of organ meat.
Anki NihongoShark.com Kanji Deck
“There’s this program called Anki, which works both on your desktop computer but also on your phone. I think it costs like $25 or something like that, but it’s well worth it, and you can synchronize them. It’s basically a platform for flashcards, and people have uploaded all kinds of flashcards decks for all kinds of subject matter: sciences, chemistry, physics, pathology, history. All kinds of thing you want to learn about, there are flashcard decks on those things. Well, someone has put together a particular flashcard deck around Kanji that I really like, and it’s called NihongoShark Kanji. So it has the 2200 Kanji that you need to learn to be basically proficient, and then it has their meanings in English on them — and it has some of the Japanese as well — and so you can learn them. ….What’s wonderful about Anki is it doesn’t just give you the new cards that you’re supposed to learn this day, but it also goes through and reviews the previous ones that you’ve supposedly learned and maybe have forgotten. It takes you back to them, and so it’s continually reinforcing your learning while it’s having you learn new things.”
Pimsleur Approach Gold Japanese I,II,III, IV Complete 64 Cd’s Total
“Pimsleur makes language CDs for all kinds of languages, and I’ve found their stuff to be really good. The particular one that I’m using is Pimsleur Approach Japanese Levels 1-4 Gold Edition, and you can get 64 CDs combined, and you can get it on eBay used for like $100. So for essentially like 60 hours of learning, that’s really pretty inexpensive. It’s very high-quality. The language instruction is great. They take you through conversations, they teach vocabulary. It has a good pace. It has male and female speakers, so you’re hearing multiple people say the same words but also different genders. Sometimes you can’t quite make out a sound, but then you’ll hear the other person say it and suddenly it makes sense. Great conversation examples that are useful for the traveler.”
A Guide to Japanese Grammar ($19)
“As I said, I’m taking a multi-pronged approach, learning the Kanji, learning the listening and speaking, but also grammar, of course, is essential. And so you want to find a book that isn’t too dry. You want to find one that is practical, and I really like this book A Guide to Japanese Grammar by Tae Kim. His name is Korean. I don’t think he’s a native Japanese speaker, and so that means that he has some perspective on the process of learning as an adult. … He’ll make sentences that aren’t really sentences in English, but they are sentences in Japanese or they’re concepts, and so you really get this sense from the very beginning of the way the Japanese think in terms of their language, and I think that’s a really important thing to do.”
JapanesePod101 Youtube Channel
“A great part of learning a language is trying to get immersed as much as possible in the culture and see how it works in real life, and what I love about JapanesePod101 is it has those real-life aspects where they’ll go and they’ll do something. They’ll go to tea shop, and they’ll talk to the guy that sells tea, and they’ll see what the tea is all about. And so it’s these real-world activities, the kinds of things you want to do as a tourist. Now, what’s great about it also is you have English subtitles. So they may be talking Japanese, you see the English subtitles. But more than watching a Kurosawa movie, you also have the Japanese there often with it. So you will have the spoken Japanese, you’ll have the written Japanese in full Kanji and Hiragana, you’ll have the Latin alphabet transliteration, and then you’ll have the English. But what’s great about YouTube is … Once they say something, you can pause, see all the text together, take your time, and learn it.”

The "duct tape" of all caulks
They call this stuff caulk, but I use it as a general purpose glue. It pretty much sticks anything to anything. It may not hold as strongly as epoxy, but for 90% of my attachment jobs it does the trick. Almost everything in my mobile illusions museum is adhered with Lexel. It sticks better than silicone sealant and is not as obnoxious to work with.
Used to stick everything to everything.

Lite-weight stove burns fuel found along trail
There I was, in driving rain, cooking breakfast under a tree over an intense, portable fire. Fresh coffee and scrambled eggs.
It was a Sierra Stove I got for $52. It’s a mini-forge, forcing air into a small insulated chamber where a double handful of twigs (or dung or whatever) can heat water in a couple minutes—just a little longer than a butane stove, but with NO fuel or fuel containers to carry. One enthusiast hiked from Mexico to Canada cooking with one, claims Chip in The Compleat Walker IV. Chip himself now claims to camp largely solar–with backback solar charged batteries running his flashlights and his Sierra Stove.
The basic unit I got weighs 18 ounces and is clever and well-evolved. Accessory goodies can be found at the manufacturer’s site. The newest item is a titanium version that weighs only 10 ounces, for $129.
I was impressed at how little fuel was needed, and how funky it could be. A switch offers high or low speed on the fan, driven by one AA battery. No igniter — my Bic failed me in the rain, but a Lifeboat match and lil’ firestarter saved the day. Unlike butane, the Sierra Stove does blacken your pots and pans, which is the main nuisance — they go in Ziploc bags anyway though. All in all an impressive little rig.
We’ll all want one when the economy collapses completely and we have to live homeless.06/20/18

Round up of inexpensive resistor kits
In this video I’m going to show you 5 different resistor kits for electronic projects. I found all of these on Amazon.
Whether you’re just getting started with electronics or you’re an old pro, a well organized assortment of resistors is incredibly useful.
The good news is that there are a bunch of options you can quickly get on Amazon. The bad news is that the quality and organization is hit or miss. So I’m going to show you 5 options.
Let’s start out with this one from Yobett. On paper, this one seems like a crazy deal for around $17. You get 166 different ¼ watt resistor values, 10 resistors per value. It comes packed and labeled and there’s a little chart inside with all the values listed.
But I have two problems with this. First, once you dig around for the resistor you need the organization falls apart almost immediately.
Second, the leads on these resistors are these thin, wimpy legs that aren’t breadboard friendly. And I’ve found this problem with a lot of resistors I’ve bought through eBay or Amazon. If you’re used to a solid, Radio Shack style of resistor lead, these will disappoint.
Next up, at just $9, there’s the RexQualis 22 value kit. You get 550 ¼ watt resistors, all separately bagged and labeled with big, legible numbers. It also includes a resistor code cheat sheet.
I like this set. The organization is great. There’s not a lot of different values, but you get the most useful and common range, from 10 ohms up to 1 megaohm. My only complaint is that the resistors still have these wimpy legs, similar to the other kit. Fine for through-hole PCB projects, but not great for breadboarding or point-to-point stuff.
Next up is the Elegoo resistor kit. It’s around $11, and comes with 525 ¼ watt resistors across 17 values.
This one comes in a neat, plastic case. Each value comes in its own individual bag, clearly labeled. You also get a resistor code chart and a list of all the included values.
The problem with this one is that there’s no linear order to how it’s organized, or any way to really keep them in order. You just hunt for what you want throw it back in.
The leads are a little stiffer on these guys. You can breadboard with these, but they’re still a little squishy.
Now here’s my personal favorite. This 16 value kit from Joe Knows Electronics isn’t the best value or most complete kit. But for around $8 you get an individually bagged assortment that’s clearly labeled and will stay organized.
The leads are relatively stiff. They’re a classic beige color because they’re 5% carbon film style. And you get a code chart inside the lid. A few extra values in here would be nice, but this covers the most common breadboard project values, and there’s enough room in here that I could pop in a few bags from the other kits and keep them organized here.
Now, I was so impressed by the way they did this kit that I also ordered up their $20 860 piece kit with 86 values.
It’s the same idea, but the box is larger, you get more values, and the resistors themselves are a more precise quality that use copper leads. I find the whole thing a little overkill for me, and honestly none of these really delivered the old school lead stiffness I was hoping for.
So that’s a look at some of the different resistor kits you can buy on Amazon. There are a bunch out there, but my advice after looking at all of these is to consider organization over quantity.06/19/18

Designed for tasks all over the house
I don’t consider myself a great cook, but I’ve found that for a multitude of kitchen activities, scissors are important. Whether for cutting cooking twine, small bones or a chicken breastbone, they can be very useful. Normal office scissors don’t have the right length of blade and the joint can harbor germs and food residue.
The Fiskars shears are one of a number of scissors specially made for the kitchen. They feature shorter, stainless steel blades and a take-apart joint for cleaning. However, these shears are one of the least expensive, yet still reliable pairs. — AK
Shoot, we keep pairs of these in the kitchen, office & home desk drawers and my tool bag. These are the epitome of a Cool Tool, perfectly functional, simple, clean and comfortable. — Wayne Ruffner06/18/18

Better than sandpaper
It’s time for another Cool Tools review. This time we’re looking at this Ultra-Flexible sandpaper by 3M. I got four sheets of this for around $7 on Amazon, which is kinda pricey for sandpaper but I’ll show you why it’s special.
We’re all familiar with sandpaper. Sometimes, there’s just no substitution for sanding something by hand.
These Ultra Flexible sheets aren’t paper at all. The grit is backed by a smooth plastic film that feels like packing tape, but stretchy. It is the limpest, floppiest sandpaper I’ve ever used. And honestly it weirded me out when I first tried it. It’s a very different feel.
But there are some huge advantages. The packaging states that it lasts 15 times longer than conventional sandpaper, but it doesn’t say why.
One reason is that it doesn’t rip. You could destroy it if really try, but the plastic back would rather stretch than rip.
It also doesn’t crease. I can fold it, I can roll it up, I can form it around complex shapes, I can crinkle it up into a little ball if I want — but it just goes back to being this floppy sheet of sandpaper. So it’s very versatile.
It can also be used wet or dry, since there’s nothing to get soggy. The flexibility makes it resistant to clogging. And you can shake them out like a rag, or whip them on the table if you need to knock anything loose.
They’re cool. I’m glad I have them. They come in Medium, Fine, and Extra Fine grit. I’ve been keeping a Medium sheet rolled up at my workbench that I use almost like a sanding rag. Mark from Cool Tools has been using these for sanding the wooden spoons that he whittles.06/17/18
