Welcome back, Ben Krasnow!

We first talked to Ben 8 years ago.

YouTube has changed quite a bit since then, as has Ben's channel:

It's now called "Applied Science" instead of the original bkraz333 (though that link is still the official one)

It now has 600k viewers and many Patreon sponsors

When Chris asked about replicating the paper setup (like from a research paper), Ben says it's a recipe. It's easier to follow and get started.

An artist had exclusive license to use

Vantablack, which made Ben wonder if he could make some. (spoiler: he can)

Applied Science gets lots of great feedback from technical viewers, including some who have insider knowledge.

Since the last episode Ben was on he worked at

Valve Software, with past guests

Jeri Ellsworth

Jeff Keyzer

Alan Yates

After Valve, Ben went to go work for GoogleX in 2014. They wouldn't tell him what he was working on!

At 6 years, this is his longest running gig.

Joined science team with 20 people, which has grown into Verily Life Sciences. He's able to talk about (some) things now.

Ben has been on Embedded.fm twice in the meantime:

Verily announced an accommodating contact lens, which helps with presbyopia

Though Ben didn't work on that project, he had previously made am LED contact lens

Verily have a micro-fab on site for making and prototyping such small devices.

Ben's lab is a bit more simple, he says it almost looks like his home lab.

Chris compared the research portions to Bell Labs

When the team hits a wall, they focus on finding and integrating new tech.

Chris asks if the development is a push or a pull. As in, does the customer request certain technology or do they "deliver" it to the market and test whether it will work?

Verily is working with a US centric view, especially given the high costs of the US medical system.

Being an inventor type person in healthcare includes figuring out what the market looks like

How much iteration?

Verily have made hundreds of certain devices to test whether they can be manufactured "at scale" and that they will work in large numbers.

Primarily they partner with other (medical) hardware makers and Verily licenses the tech to the OEM.

A common demo in the Verily lab is a little motor that uses combustion because battery technology isn't power dense enough for what they need

Ben often gets comments about safety on the YouTube channel

He likes to be application driven

Wikipedia op amps

Ben is a KiCad user, he likes the push and shove feature.

One of his most popular video shows vinyl and LP under a SEM. The tough part is pulling out the bitstream, which he currently does with a Teensy.

Rubber band fridge

Drill through EDM

Ben tried over 80 different methods to get PCB traces on a piece of plastic. This is a good example of the importance of starting from a paper or a patent.

Chris thinks that Ben is a great example of the behavior defined in Grit

Tim Ferriss talking about fame/money

Cookies DOE

Exceptionally hard and soft

Ben kept blowing up the controllers for the Apollo Electroluminescent display. Ben later gave a great talk about the experience at Supercon

Needed a source of radioactive material, which are apparently easily acquired in static brushes for LPs.
