Beat This Mario Block Like it Owes You Moneymarioblock_feattomnardi

Wed, 25 Apr 2018 11:00:00 +0000

People trying to replicate their favorite items and gadgets from video games is nothing new, and with desktop 3D printing now at affordable prices, we’re seeing more of these types of projects than ever. At the risk of painting with too broad a stroke, most of these projects seem to revolve around weaponry; be it a mystic sword or a cobbled together plasma rifle, it seems most gamers want to hold the same piece of gear in the physical world that they do in the digital one.

But [Jonathan Whalen] walks a different path. When provided with the power to …read more

Smart Outlet Cover Offers Lessons on Going from Project to Productoutletdpsm64

Wed, 25 Apr 2018 08:00:28 +0000

Going from idea to one-off widget is one thing; engineering the widget into a marketable product is quite another. So sometimes it’s instructive to take an in-depth look at a project that was designed from the get-go to be a consumer product, like this power indicating wall outlet cover plate. The fact that it’s a pretty cool project helps too.

Although [Vitaliy] has been working on this project for a while, he only recently tipped us off to it, and we’re glad he did because there’s a lot to learn here. His goal was to build a replacement cover for …read more

Temperature Sensor and Simple Oscillator Make a Value-Added HF Beaconoriginaldpsm64

Wed, 25 Apr 2018 05:00:14 +0000

Sometimes the best projects are the simple, quick hits. Easily designed, fast to build, and bonus points for working right the first time. Such projects very often lead to bigger and better things, which appears to be where this low-power temperature beacon is heading.

In the world of ham radio, beacon stations are transmitters that generally operate unattended from a known location, usually at limited power (QRP). Intended for use by other hams to determine propagation conditions, most beacons just transmit the operator’s call sign, sometimes at varying power levels. Any ham that can receive the signal will know there’s …read more

Neural Networks… On a Stick!pynqwd5gnr1

Wed, 25 Apr 2018 02:00:47 +0000

They probably weren’t inspired by [Jeff Dunham’s] jalapeno on a stick, but Intel have created the Movidius neural compute stick which is in effect a neural network in a USB stick form factor. They don’t rely on the cloud, they require no fan, and you can get one for well under $100. We were interested in [Jeff Johnson’s] use of these sticks with a Pynq-Z1. He also notes that it is a great way to put neural net power on a Raspberry Pi or BeagleBone. He shows us YOLO — an image recognizer — and applies it to an HDMI …read more

First Lithographically Produced Home Made IC Announcedzeloof-chip-featuredjennylist

Tue, 24 Apr 2018 23:00:29 +0000

It is now six decades since the first prototypes of practical integrated circuits were produced. We are used to other technological inventions from the 1950s having passed down the food chain to the point at which they no longer require the budget of a huge company or a national government to achieve, but somehow producing an integrated circuit has remained out of reach. It’s the preserve of the Big Boys, move on, there’s nothing to see here.

Happily for us there exists a dedicated band of experimenters keen to break that six-decade dearth of home-made ICs. And now one of …read more

Former Smoker Now Pats Pockets for Motivationquit-smoking-800cornbreadninja

Tue, 24 Apr 2018 20:00:15 +0000

It’s hard to quit smoking. Trust us, we know. Half the battle is wanting to quit in the first place. Once you do, the other half is mostly fighting with yourself until enough time goes by that food tastes better, and life looks longer.

[Danko] recently quit smoking. And because idle hands are Big Tobacco’s tools, he kept himself busy through those torturous first few days by building a piece of pocket-sized motivation. This little board’s main purpose is to help him root for himself by showing the time elapsed since his final cigarette, the number of cigarettes he has …read more

Custom Chips As A ServiceCustomSiliconHeaderbrianbenchoff

Tue, 24 Apr 2018 18:30:59 +0000

Ages ago, making a custom circuit board was hard. Either you had to go buy some traces at Radio Shack, or you spent a boatload of money talking to a board house. Now, PCBs are so cheap, I’m considering tiling my bathroom with them. Today, making a custom chip is horrifically expensive. You can theoretically make a transistor at home, but anything more demands quartz tube heaters and hydrofluoric acid. Custom ASICs are just out of reach for the home hacker, unless you’re siphoning money off of some crypto Ponzi scheme.

Now things may be changing. Costs are coming down, …read more
