Peloton Bike ($1,995)

“I had taken a couple stationary bike classes and the ones that you actually have to go in person, but then I had a buddy of mine, that was like you don’t understand, these classes are a lot of fun, they really motivate you, you can do it your house, and for me that just sounded like, okay, I’ll give it a shot, and I went and tried it at a friend’s house, and I got hooked, purchased one, and for a geek it's awesome because you get all the really detailed analytics on the screen there post workout, and then it's all live streaming classes, so like when you're in a class the instructors will call you out by name sometimes, and there's all different types of instructors depending on your music style and likes, so I've just found it to be a great way — if you have an extra half hour — to just jump on for 20 minutes and get a work out in." [Note: True Ventures, the venture capital firm Kevin Rose works for, is an investor in Peloton.]

Habitify: Habit Tracker

"I've been into habit tracking apps, but they always kind of fall off, but as a data junkie, and kind of a geek, I really like to see and be held to certain habits, so I like to see like completion rate, and progress indicators, and little charts and graphs. Read the rest

Watch how 19th-century Genaille-Lucas calculating rulers work

Multiplying large numbers before calculators led to a number of ingenious inventions to make things easier, like these Genaille-Lucas rulers demonstrated by the fine folks at DONG.

Via manufacturer Creative Crafthouse:

In the days before calculators, methods of simplifying calculations were of much interest. In 1617 Napier also published a book describing a method to multiply, divide and extract square roots using a set of bars or rods. These became known as Napier's Bones. (avail on our website)

In the late 1800s, Henri Genaille, a French civil engineer, invented an improvement to Napier's Bones that eliminates the need to handle carries from one digit position to the next. The problem was posed by Edouard Lucas and thus the alternate name of Genaille-Lucas Rulers (or Rods).

There are also sets for division. You can get your own set online or print your own from these free files.

Taylor Wharton LD10 Aluminum Liquid Dewar ($638) “I’m often asked to demonstrate scientific toys and things at different science conventions, like the Google Science Fair … and one of the things that they love when I show off is all of these fun things that you can do with liquid nitrogen. And, of course, it lasts a lot longer if you keep it in a big Dewar. So, I’ve got this thing, it’s about 2 feet tall, about 10 inches in diameter, And holds 10 liters of liquid nitrogen, which I get locally from a place called Nitroderm. And we do all kinds of fun things with it. Put some liquid nitrogen in a bowl and squirt some whipped cream out of a spray can into it, freeze it really hard. Kids pop it into their mouth and crunch on it and fog comes out their nose like a dragon.”

Here's a video for a spokeshave, which rounds off wood edges:

AmazonBasics High-Density Foam Roller ($19) "I work with a physical therapist, I had lots of surgeries and stuff, and when I travel, I get sore. I didn’t realize how cheap foam rollers on Amazon are, if you're just doing like the cheapo, basic, no kind of weird serrations, no crazy Space Age material, but just basically a 36-inch foam roller about six-inch diameter. I overnighted one of those things to myself here in Utah the day that I arrived. … I can stretch out everything that gets stiff, either from exerting myself on hiking trails, or just getting out there.

Use these handy bits to drill out stripped screws and bolts

When a bolt or screw is stripped, I drill it out with this extractor set.

When working on old motorcycles, or just my old VW bus, I encounter a lot of stuck screws and bolts. Frequently prior mechanics have left fastners completely rounded off. When these things happen, I grab my drill.

These extractor bits both burnish the stripped head, and then screw into it and extract it. They are not simple to use, and it takes a very steady hand -- something I don't always have -- but slow and patient work generally produces good results.

Interview with Nick Bilton, author of new book about The Silk Road, American Kingpin

In this week's Cool Tools Show podcast, Kevin Kelly and I interviewed Nick Bilton. Nick is a Special Correspondent for Vanity Fair and author of three books, including Hatching Twitter and his latest, American Kingpin, which chronicles the rise and fall of the Silk Road and the Dread Pirate Roberts.

Here's a bit from the interview:

Mark: I feel, in a lot of ways, the story of the Dread Pirate Roberts, aka Ross Ulbricht, is kind of like Breaking Bad.

Nick: Yeah, it's a kid who was the sweetest, nicest kid, who decided to build this website where you could buy and sell drugs, because he believed they should be legal and it spiraled out of control. Next thing you know he's running an empire that's making hundreds of millions of dollars, and ordering hits on people from the Internet, and selling guns and drugs and you name it in between.

Mark: And every three letter acronym government agency after him and competing with each other to get him.

Nick: Yeah, every single one. IRS, DHS, HSI, FBI, you name it.

Kevin: Sounds like a movie.

Mark: Yes. More than one of those agencies going rogue too. It's got everything. The way you tell it too, it's like a novel. The amount of research you must've put into this is incredible, because the conversations you have, there's stuff ... Kevin and I were saying, we follow this story, but it's like your other book, Hatching Twitter, it's being there ... Read the rest

Niice.com

"For my work at Institute for the Future we're often trying to distill these nebulous concepts about the future into images and into words that people can understand. It’s really important that we get the visual part down right, but most sites aren’t really great for visual inspiration. … but Niice is this incredible site that shows you really creative imagery and often a lot of original art from artists, which is great because sometimes it can be hard to access the people doing really interesting creative work. Niice is meant, I believe, for designers and for design firms to do premium mood boards. … The great thing about this site is it can make me associate new concepts actually that I hadn’t before. It’s a really neat way to think about the future visually."

Dremel 4200 ($114) “I started building stuff about 3 years and I’m rediscovering everything that people have known for a long time. … Dremel tool kind of goes in the line of that … it blew my mind because I do a lot of aluminum fabrications. I make parts out of aluminum frames or customized parts that I already have and for that it's freakin' great because it's like having your own arm do it but at a much higher RPM. It's like a little pen. It's just such an accessible tool. You're just sitting there and you're cutting. It has the tiniest little cutter blades and it’s just nice. … It’s a super versatile tool and it takes up no space.”

Allbirds ($95)

"I feel slightly irresponsible for advising people to buy $95 shoes. I didn't think I would do that either, until I put these on. Now I get it. I'm converted. Allbirds are very new and they're fantastic. ... They're not like technical running shoes or anything like that, they're sort of lounging shoes. They're all merino wool from New Zealand. They're so comfortable. … It's been the shoe I've been wearing every day since I got them, because I've just been going to work and doing my business. I just suggest people give it a shot and if they don't like them, they can send it back. It's free returns and all that stuff."

Cold Saw (varies), also TechShop membership

"I think this is my favorite tool of all time. I didn't even know about it until a few years ago. … It's slow, which is very perplexing. It's so slow that you can just see the individual teeth rolling around. It's like 100 RPM. It makes these perfectly smooth cuts. There's like a little burr that you can knock off with a file. It makes smooth cuts, it makes them square, it makes them fast, it's really safe. Read the rest
