Ask Hackaday: Would A Scooter Get You Back To The Office?

April 18, 2022 by Kristina Panos 75 Comments

So we’re two plus years into the pandemic at this point. Are you still working from home in the most comfortable clothes ever sewn? We figure that of the lot of you who said goodbye to that drab, tiled carpet in 2020, most have probably heard rumblings about returning to the office. And probably a good portion have at least been forced into a hybrid schedule.

Lots of companies would love to see their employees once again milling about all those ~~glass and steel observation tanks~~ office buildings they pay so much for. And while some are likely just forcing employees to come back, others are offering incentives, such as Google. The tech giant recently partnered with electric scooter manufacturer Unagi to provide a “Ride Scoot” program designed to lure many of Google’s US-based employees back to those brightly-colored code playgrounds they call offices with a fun mode of private transportation. The plan is to offer a full reimbursement of the monthly subscription fee for Unagi’s Model One folding scooter, which retails for $990.

The subscription is normally $49 a month plus a one-time $50 sign-up fee, but this amount will be slightly discounted (and waived) for eligible Google employees. There is one caveat to the system: an employee must use the scooter for a minimum of nine commutes to the office per month, although Google says they’re gonna be a bro about it and use the honor system.

Ask Hackaday: What’s Your Worst Soldering Job?

February 24, 2022 by Lewin Day 114 Comments

Soldering! It’s the primary method for attaching one component to another in the world of electronics. Whether you’re free-forming a circuit, attaching connectors to cables, or populating a PCB, you’ll eventually find yourself doing some soldering, whether by hand, reflow, or maybe even a fancy wave soldering machine.

It’s a fundamental skill that nevertheless remains one of the biggest hurdles for newcomers to overcome when diving into the electronics hobby. Difficult jobs with tiny components or with large heat sinks can up the challenge for even well-practiced hands. Thus, today we ask the question: What’s your worst soldering job?

Ask Hackaday: Are Extruders The Only Feasible Tools For Toolchanging?

December 13, 2021 by Donald Papp 34 Comments

Toolchanging in 3D printers is no longer something from the bleeding edge; it’s going mainstream. E3D has a high-quality kit for a toolchanger and motion system, our own Joshua Vasquez has shared details about the open-source toolchanging Jubilee design, and just recently Prusa3D formally announced the Prusa XL, which promises toolchanging with up to five different extruders.

It’s safe to say toolchanging on 3D printers has stepped to the front, but what comes next? What kind of tools other than extruders make sense on a 3D printer?

First, let’s explain what makes separate extruders such fantastic tools. Being able to change extruders on-demand during a print enables things like true multi-material printing. Printing in more than one color or material will no longer be done by pushing different filaments through a single nozzle, which limits a print to materials that extrude under similar conditions and temperatures. Toolchanging means truly being able to print in multiple materials, even if they have different requirements, because each material has its own extruder. That’s a clear benefit, but what about tools other than extruders?

Ask Hackaday: Why Don’t Automakers Make Their Own EV Batteries?

December 1, 2021 by Lewin Day 88 Comments

Sales of electric vehicles continue to climb, topping three million cars worldwide last year. All these electric cars need batteries, of course, which means demand for rechargeable cells is through the roof.

All those cells have to come from somewhere, of course, and many are surprised to learn that automakers don’t manufacture EV batteries themselves. Instead, they’re typically sourced from outside suppliers. Today, you get to Ask Hackaday: why aren’t EV batteries manufactured by the automakers themselves?

Ask Hackaday: What Can Only A Computer Do?

September 22, 2021 by Al Williams 128 Comments

It is easy to apply computers to improve things we already understand. For example, instead of a piano today, you might buy a synthesizer. It looks and works — sometimes — as a piano. But it can also do lots of other things like play horns, or accompany you with a rhythm track or record and playback your music. There’s plenty of examples of this: word processors instead of typewriters, MP3 players instead of tape decks, and PDF files instead of printed material. But what about something totally new? I was thinking of this while looking at Sonic Pi, a musical instrument you play by coding.

But back to the keyboard, the word processor, and the MP3 player. Those things aren’t so much revolutionary as they are evolutionary. Even something like digital photography isn’t all that revolutionary. Sure, most of us couldn’t do all the magic you can do in PhotoShop in a dark room, but some wizards could. Most of us couldn’t lay out a camera-ready brochure either, but people did it every day without the benefit of computers. So what are the things that we are using computers for that are totally new? What can you do with the help of a computer that you absolutely couldn’t without?

Ask Hackaday: What’s The Best Way To Heat A Tent With A Laptop?

September 16, 2021 by Jenny List 49 Comments

For Europeans, August is usually a month of blistering heatwaves, day after day of cloudless skies and burning sun that ripens fruit and turns we locals a variety of shades of pink. Hacker camps during this month are lazy days of cool projects and hot nights of lasers, Club-Mate, and techno music, with tents being warm enough under the night sky to dispense with a sleeping bag altogether.

Sometimes though, the whims of the global weather patterns smile less upon us hackers, and our balmy summer break becomes a little more frigid. At BornHack 2021 for example we packed for a heatwave and were met with a Denmark under the grip of the Northern air mass. How’s a hacker to keep warm?

Ask Hackaday: What Is Amazon Thinking By Entering The Palm-Reading Business?

August 27, 2021 by Kristina Panos 60 Comments

Have you heard about this One? At least three United States senators have, and they want to know what Amazon plans to do with all the biometric data collected by the Amazon One program. It’s their new contactless payment method that uses your unique palm print instead of cards or phones to make purchases, gain access to venues of work and play, and enter or pay in whatever other spaces Amazon can invade down the line. The idea is that one day, we’ll all be able to leave our homes without any form of money or ID of any kind, because we’ll all be stored away in Bezos’ big biometric file cabinet.

We tossed this one around in the writer’s room back when the Amazon One concept was nothing but a pile of buzzwords and a render or two, but these kiosks are now active in 50+ Whole Foods and Amazon 4-Star locations across the US. Here’s the deal: you can only sign up at a participating store that has a kiosk, because they have to scan your palms into the system. We were worried that the signup kiosk could easily take fingerprint scans at the same time, but according to the gifs in Morning Brew’s review, it just uses another of their point-of-sale palm scanners along with a touch screen and a card reader. But you still have to hover your entire hand over it, so who’s to say that the scan ends where the fingers begin?
