You Can Build Anything Out Of What Is Holding Your 97 Eagle Talon Together

1 Comment

We all know it, we all love it, and the guy parked outside of the 7-11 covered his car in it. What is it? Polyester body filler, better known by the almost generic trademark, Bondo. There’s a lot more you can do with Bondo than fairing in that sweet body kit, bro, and [Eric Strebel] is here to show you how far you can push the mechanical properties of polyester body filler.

We didn’t always have polyester body filler. In the days before OSHA, auto body workers would use a torch, bricks of lead, and a grinder. You can check out a video of the era before OSHA here. Needless to say, vaporizing and grinding lead in your shop isn’t the greatest idea, and there had to be a better way. This led Robert ‘Bondo Bob’ Spink to invent a much less toxic auto body filler that we now know as Bondo.

For the beginning of the demonstration, [Eric] mixes up a cup of polyester body filler with a few special additions: he’s using printer ink to get his mixture to something other than that one shade of pink we all know. Although Bondo is a bit too thick to cast, he did manage to put a little bit of it in a square mold, a PVC pipe, and applied a little to foam and wood. It’s enough for a demonstration, but for the actual ins and outs of machining Bondo we’re going to have to wait until [Eric]’s next video. Until then, you can check out this introduction below, or look at his previous work on free-form sculpting of uncured Bondo.

My grandfather metalworked the fenders of my '53. He was retired and still had the skill.

"If ecstasy becomes your baseline experience, is it really ecstasy anymore?"

Uh... yes? I can say from experience that when happiness becomes my baseline, I'm still happy, and when depression becomes my baseline, I'm still miserable.

Also, some types of drug addiction are all about that shifted baseline causing cravings in their absence, so really none of this makes sense.

How to Photograph a Moonrise and Moonset

1 Comment

Want to learn how to predict and photograph a moonrise or moonset? Here’s a helpful 5-minute video on just that by photographer Matthew Saville of Nature TTL.

Every month there is a full moon, and this is the perfect time to capture the moon on camera. The moon will rise and set perfectly with sunrise and sunset, meaning that you have (potentially) beautiful colors in the sky to make an impactful lunar image.

To help with moonrise and moonset photography, there are a number of apps that will allow you to utilize augmented reality to “see” the position of the moon via your smartphone.

Saville recommends 3 apps in particular: PhotoPills, Sun Surveyor, and The Photographer’s Ephemeris. Each of these apps will show you the precise positioning of the moon, allowing you to line-up a composition in advance so that you aren’t relying on “getting it right on the night.”

Sometimes you may need to take a number of exposures of the scene, blending them together later during post-production, to ensure a properly exposed moon and landscape. These are all important considerations, but if you do mess up the first time around then you can try again next month!

Check out the full video above to see tips from Saville about how to compose a successful lunar landscape photo, and subscribe to the Nature TTL channel for weekly nature photography tutorials.


Full disclosure: I own and operate the Nature TTL channel.

Calculating Like It’s 1962

2 Comments and 3 Shares

We sometimes forget that the things we think of as trivial today were yesterday’s feats of extreme engineering. Consider the humble pocket calculator, these days so cheap and easy to construct that they’re essentially disposable. But building a simple “four-banger” calculator in 1962 was anything but a simple task, and it’s worth looking at what one of the giants upon whose shoulders we stand today accomplished with practically nothing.

If there’s anything that [Cliff Stoll]’s enthusiasm can’t make interesting, we don’t know what it would be, and he certainly does the job with this teardown and analysis of a vintage electronic calculator. You’ll remember [Cliff] from his book The Cuckoo’s Egg, documenting his mid-80s computer sleuthing that exposed a gang of black-hat hackers working for the KGB. [Cliff] came upon a pair of Friden EC-132 electronic calculators, and with the help of [Bob Ragen], the engineer who designed them in 1962, got one working. With a rack of PC boards, cleverly hinged to save space and stuffed with germanium transistors, a CRT display, and an acoustic delay-line memory, the calculators look ridiculous by today’s standards. But when you take a moment to ponder just how much work went into such a thing, it really makes you wonder how the old timers ever brought a product to market.

As a side note, it’s great to see the [Cliff] is still so energetic after all these years. Watching him jump about with such excitement and passion really gets us charged up.

Thanks to [Mark] and [Jerrad] for the near-simultaneous tips on this one.

Remember, Stoll said the internet was a fad.
