Brushless HDD Motor Driver from 9V and Painter’s Tape

Posted on by

Hard drives work by spinning platters full of magnetized data while a read/write head very quickly harvests or changes bits as needed. Older (or perhaps cheaper) drives spin at 5400 RPM, better drives spin at 7200 RPM, and elite drives (that mortals like you never shell out for) spin in the 10k-15k RPM range. This spinning is thanks to a sweet combination of a bearing and a brushless DC motor.

Unfortunately you can’t drive a brushless motor without a brushless motor driver. Well, of course that’s not absolutely true — and [Tommy Callaway] has certainly hacked together a crude exception …read more

[Geohot] Selling His “Self-Driving” Car Tech for $1k by New Year

Posted on by

This week [Geohot] announced the launch of his self-driving car hardware. This is the natural extension of his proof-of-concept shown off in December which he parlayed into a Silicon Valley startup called comma.ai. [Geohot], whose real name is [George Holtz], is well know for jailbreaking the iPhone and making Sony look like idiots when they retroactively crippled Linus support on PS3. He has hardware chops.

Initial self-driving add-on hardware only works with Honda and Accura models that already have lane-keeping assist features because those vehicles already have built-in front radar. The package, which replaces the rear view mirror, adds a …read more

Smartphone TV Remote Courtesy of Homekit and ESP8266

Posted on by

Good grief, this smartphone-to-TV remote really drives home how simple hardware projects have become in the last decade. We’re talking about a voltage regulator, IR LED, and ESP8266 to add TV control on your home network. The hardware part of the hack is a homemade two sided board that mates an ESP with a micro-USB port, a voltage regulator to step down fom 5 to 3.3 v, and an IR LED for transmitting TV codes.

Let’s sit back and recount our good fortunes that make this possible. USB is a standard and now is found on the back of most …read more

A Better Way to Measure Your Impact on the World

Posted on by

Close your eyes and think of an electric wheelchair. What do you see? Is it sleek, futuristic, and elegant… worthy of the moniker: iChair? No, no it is not. It’s a boxy tank-like thing with grey knobbed wheels that is powered with lead-acid batteries. Why is that?

Obviously there are alternatives. Just yesterday I came across UPnRIDE (that name is sore on the eyes but speak it aloud and you’ll get it). It’s an electric wheelchair that converts into a standing position. And it looks comparatively sleek and modern. And it’s not the first time I’ve seen the idea before. …read more

VW Engineer Pleads Guilty To Conspiracy

Posted on by

[James Liang], an engineer at Volkswagen for 33 years, plead guilty today to conspiracy. He was an engineer involved in delivering Diesel vehicles to market which could detect an emissions test scenario and perform differently from normal operation in order to pass US emission standards.

A year ago we talked about the Ethics in Engineering surrounding this issue. At the time we wondered why any engineer would go along with a plan to defraud customers. We may get an answer to this after all. [Mr. Liang] will cooperate with authorities as the VW probe continues.

According to information in the …read more

Let’s Make Life A Little Better

Posted on by

Chances are you’ve spent a lot of time trying to think of the next great project to hit your workbench. We’ve all built up a set of tools, honed our skills, and set aside some time to toil away in the workshop. This is all for naught without a really great project idea. The best place to look for this idea is where it can make life a little better.

I’m talking about Assistive Technologies which directly benefit people. Using your time and talent to help make lives better is a noble pursuit and the topic of the 2016 Hackaday …read more

Asking the Security Question of Home Automation

Posted on by

“Security” is the proverbial dead horse we all like to beat when it comes to technology. This is of course not unjust — we live in a technological society built with a mindset of “security last”. There’s always one reason or another proffered for this: companies need to fail fast and will handle security once a product proves viable, end users will have a harder time with setup and use if systems are secured or encrypted, and governments/law enforcement don’t want criminals hiding behind strongly secured systems.

This is an argument I don’t want to get bogged down in. For …read more

Home Automation Is Hung Up On Software

Posted on by

Home automation is a favorite in sci-fi, from Tony Stark’s Jarvis, to Rosie the robotic maid on the Jetsons, and even the sliding doors pulled by a stagehand Star Trek. In fact, most people have a favorite technology that should be just about ready to make an appearance in their own home. So where are these things? We asked you a few weeks ago and the overwhelming answer was that the software just isn’t there yet.

We’re toddling through the smart home years, having been able to buy Internet-connected garage doors and thermostats for some time now. But for the …read more
