Resurrecting Duckhunt

Bringing old things back to life holds a great sense of joy for most people. The never ending pursuit of recapturing our youth leads us down roads we’ve long forgotten. Along the way, we tend to bump into forgotten memories which jostle other forgotten memories which allows us to relive happy times we haven’t thought of in years, sometimes even decades. For some, the roar of a 351 small block sweeps them back to high school and the fast nights of cruising down main street with the FM radio cranked up as high as it would go.  For those of us who were born in the 80’s and 90’s, video games can bring back such memories. Who among us can forget our first encounter with Link, the elegant theme music of Final Fantasy or up-up-down-down-left-right-left-right-b-a-select-start?

Advances in processor technology has allowed us to relive our favorite games via emulators – programs that emulate processors of older computers. The games are ‘dumped’ from the ROM chips (where they are stored) into files. These game files can then be loaded into the emulator program, which allows you to play the game as if you were playing it on the original system.

Guts of NES Zapper

Technology is truly a beautiful thing. It allows us to move forward, allows us to do today that which was not possible yesterday. There are a few cases, however, where this paradigm does not hold true. One of these has to do with the Nintendo Entertainment System and its “Zapper” gun controller. The NES was the most popular game console of its time, and rightfully so. From the minds of Nintendo engineers, programmers and audio experts came some of the best video games ever made. Unfortunately, some of these great games cannot be played on your Raspberry Pi favorite emulator due to the incompatibility of the Zapper gun and modern digital monitors.  None of us can forget the fun that Duckhunt brought. The game came as standard issue with all NES systems, so we’ve all played it. But its nostalgia is currently entombed by a technological quirk that has yet to be solved.

From one hacker to another – this can no longer be tolerated. First, we’re going to learn how the Zapper works and why it doesn’t work with digital displays. Then we’re going to fix it.

Hack A Padlock Key From Plastic Scraps

Not too many years ago, if you wanted a decent copy of a key made, you had to head to either a locksmith’s shop or the nearest hardware store, where real people actually knew their trade. Now we generally take our keys to the Big Orange Box o’ Stuff and have it copied by a semi-automated machine, or even feed it into one of the growing number of fully automated key-copying kiosks, with varying results. But as [BlueMacGyver] shows us, a serviceable padlock key can be whipped up quickly at home with nothing but scraps.

The video below details the process – soot the profile of the key with a lighter, transfer the carbon to some stiff plastic with Scotch tape, and cut out the profile. With a little finagling the flat copy makes it into the lock and opens it with ease. Looks like the method could be applied to locks other than padlocks. As for raw material, we think we’ve found a use for all those expired credit cards collecting in the desk drawer.

We’ve given a lot of coverage lately to hacks involving locks, including copying keys from photos and making bump keys with a 3D printer. But we like this hack for its simplicity. True, you need physical access to the key to copy it, and that limits the hack’s nefarious possibilities. But maybe that’s not such a bad thing.

EV Motor Not Powerful Enough? Make Your Own.

Many of us have tried our hand at the ol’ electric car conversion hack. Yank the engine, throw in an industrial DC or AC motor, and bob’s your uncle. Simple stuff. But if you can’t find just the right motor for your application… why not design and build your own brushless DC motor?

This mind-blowing build is by an electrical engineer who decided to design a 45kW motor (that’s 60HP). That’s not a typo. Design and build a 45kW motor! He has a video series on the design process which includes the CAD and all the calculations he did to make this thing work. Once he had the design complete and ordered the custom parts, he started building it.

In his living room.
