Ultimate Remote is Ultimate

[Joedefa] had a Griffin Beacon Universal Remote that was collecting dust, and decided that it needed to stop collecting dust. He had a growing number of wireless devices in his house and found himself in need of a remote to control them all. The Griffin Beacon fit the bill, but most of his lights and outlets were RF controlled. So he did what hackers do best… broke out the screw driver and soldering iron and rewired it!

[Joedefa] is using an Attiny85 as the brains between an infrared LED and a RF transmit module (if anyone can identify the source of this module, please let everyone know in the comments).  A pair of red and green LEDs lets him know if the remote has received commands successfully.

It’s always nice to see a discontinued product made useful once more with a little ingenuity and an Arduino some hacking skill. Hat’s off to [Joedefa] for a righteous hack!

Quadcopter Plane Transformer is Awesome

Is it a quadcopter? A plane?  No, it’s both! [Daniel Lubrich] is at it again with a vertical take off and landing transformer he calls the SkyProwler.

The SkyProwler uses a switch blade type mechanism to move from quadcopter mode to plane mode. The wings can be detached to make it a normal quad that has all the typical bells and whistles. It can follow you around with GPS, fly autonomously via way points, and has this cool gimbal mechanism that keeps the GoPro stable as the drone pitches in flight, allowing for a better video experience.

[Dan’s] ultimate goal is a full size passenger model called the SkyCruiser, which uses the same switchblade transformation mechanism as his much smaller SkyProwler. Be sure to check out the video below if you haven’t already, and let us know of any quadcopter / plane hybrids of your own.

Correction: We previously associated [Daniel Lubrich] with the ATMOS program. This was in error and has been removed from the article. The ATMOS UAV is a separate project which we previously covered.

The One Million Dollar Scope Teardown

The Labmaster 10-100zi Oscilloscope is one of the fastest scopes in the world, coming in at a blistering speed of 100GHz with up to 240 Giga samples per second in real time. The scope is made by Teledyne LeCroy, and uses a frequency interleaving technology perfected by LeCroy, which allows it to provide a single 100GHz channel, or two 33GHz channels and a single 65GHz channel. The price tag? One million dollars.

[Shahriar] takes us inside the Teledyne Lecroy factory in Chestnut Ridge, NY where these scope are manufactured, and gives us the grand tour. First, an engineer describes the interleaving frequency technique that allows the lightning fast sample rates. Then they actually tear the million dollar scope down for our viewing pleasure. And if you still want more, they put it back together and run some tests to push the scope to its far reaching limits. Lastly, [Shahriar] takes us on a tour of the plant where the scopes are built.

It’s a lengthy video, so grab your favorite beverage and tuck in! It’s shocking how fast technology progresses. Just about 18 months ago [Shahriar] took us through the then reigning champion of scopes the Agilent DSA-X 96204Q which capturered 160GS/s at 62GHz.

Ask Hackaday: Bringing Your Design to Market

While many of us have made and documented our open source projects, not many of us have tried to sell our design to the masses. [Scott] developed, marketed, and “bootstrapped” a cool looking MIDI controller. Now, before you get your jumpers in a bunch – the project is completely open source. [Scott] documented the entire process of not only the design, but the trials and tribulations of bringing it to market as well. Calculating costs, FCC testing and the many other challenges of bringing a consumer electronics device to market are all detailed in his blog. Join me while we look at the highs and lows of his interesting and eventually worthwhile journey.

Putting yourself into a game where orders are in the tens of thousands, with hundreds of thousands of dollars changing hands is not easy when you’re just a guy with an idea and a soldering iron. [Scott] was up for the challenge, however. He quickly realized that much of the margin is spent on advertising and to cover risk. On his last order, some of the paint was chipping off. He had to fix the paint and repackage everything – all at his cost.

He also talks about the learning process of product design along the way. His original idea was to make a volume controller, but couldn’t sell a single one. He was forced to redesign the software into the MIDI controller as it exists today. He tried to launch a Kickstarter, but was rejected. This turned out to be a good thing, however, because he would have wound up kickstarting a product that didn’t work.

For advertising, he relied on Google and made some extremely detailed tutorials for his product. Many of them can be used for other MIDI controllers, and often come up in Google searches. Smart. Very smart.

Be sure to check out the video below, where [Scott] gets into some capacitive touch design theory, and talks about how not to cut your final product in half while on the CNC.

Have any of you ever tried to mass produce and sell one of your designs? Let us know in the comments!

Ask Hackaday: Understanding the x86 Memory Addressing System

A quick look at the pinouts of an Intel 8086 & 8088 processor reveals a 20 bit address bus. There was high demand for the ability to address 1 meg (2^20) of address space, and Intel delivered. However, a curious individual would wonder how they can achieve such a feat with only 16 bit registers. Intel solved this riddle by combining two registers so they could make it compatible with code written for the 8008, 8080 & 8085. The process they use can be a bit confusing when trying to figure out where to locate your code in the ROM. In this article, we are going to go over the basics of how the Physical Address is calculated and how to locate your code correctly in ROM.

Arduino + Servo + Scotch tape == An Interesting Conversation

If one could temporarily remove their sense of humor and cast a serious look into a Rube Goldberg machine, they would not say to themselves “well that looks simple.” Indeed, it would almost always be the case that one would find themselves asking “why all the complexity for such a simple task?”

Too often in hacking are we guilty of making things more complicated than they really need to be. Maybe it’s because we can see many different paths to a single destination. Maybe it’s because we want to explore a specific path, even though we know it might be a little harder to tread. Maybe it’s just because we can.


But imagine approaching a hack as simply a means to an end. Imagine if you did not have all of that knowledge in your head. All of those tools at your disposal. How would this change your approach? When [yavin427] decided to automate the leveling up process in his favorite video game, odds are he had never taken a game controller apart. Had never touched an oscilloscope. Indeed, he might have no knowledge of what a transistor or microcontroller even is. While many of our readers would have taken the more difficult path and tapped directly into the TTL of the controller to achieve maximum efficiency; it is most likely that [yavin427] would not have known how to do this, and thus would not have seen the many other paths to his end goal that would have been obvious to us. Yet he achieved his end goal. And he did it far easier and with less complication than many of us would have done.

Ask Hackaday: Your Very First Microcontroller

Necessity is the mother of invention. It is also true that invention necessitates learning new things. And such was the case on the stormy Tuesday morning our story begins.  Distant echos of thunder reverberated in the small 8 x 16 workshop, drawing my attention to the surge suppressor powering my bench.  With only a few vacation days left, my goal of finishing the hacked dancing Santa Claus toy was far from complete. It was for a Secret Santa gift, and I wanted to impress. The Santa moved from side to side as it sang a song. I wanted to replace the song with a custom MP3 track. In 2008, MP3 players were cheap and ripe for hacking. They could readily be picked up at local thrift shops, and I had picked up a few. It soon became clear, however, that I would need a microcontroller to make it do what I wanted it to do.
