INVENTION killed THE innovator

The desire to innovate and change the world can drive one to take hazardous risks. Sometimes, inventors pay the utmost price. Inventors can be early testers of a device under development, and often pushing the limits of what’s possible has deadly consequences. In this era of alerting labels on coffee cups, it’s maybe worth taking a look back at some inventors of the past who lost their lives in the pursuit of building something new.

First Aviation Fatality

Jean-Francoise Pilatre de Rozier was an early aviation pioneer, as well as a chemistry and physics teacher. He and Marquis d’Arlandes made the first manned complimentary balloon flight in 1783. De Rozier is known for testing the flammability of hydrogen by “gulping a mouthful and blowing across an open flame, proving at a stroke that hydrogen is undoubtedly explosively combustible and that eyebrows are not necessarily a permanent feature of one’s face.” (Bill Bryson, in “A short history of nearly Everything”) He may have had a slightly cavalier technique to on-the-job safety.

But it was ballooning that would get him. After several successful flights, he and his companion Pierre Romain attempted to cross the English channel on June 15th, 1785, but the balloon unexpectedly deflated, and they fell from an estimated altitude of 450 m. Both pioneers were killed in the crash.

The Glider King

The first well-documented and successful heavier-than-air flights were made by German aviation pioneer Otto Lilienthal. He constructed eighteen types of gliders and took over 2,000 glider flights. He also developed a dozen models of monoplanes, flapping-wing aircraft, and two biplanes. Wilbur Wright called him “easily the most important” of the early airplane pioneers.

His final flight, on August 9th, 1896, was otherwise quite normal. His glider design had a problem with pitching nose-first, because after a certain angle the pilot just couldn’t shift their weight any additionally backwards to counteract it. Lilienthal lost control in a nose dive, falling from a height of about 15 m, and fractured his spine. He was taken to the hospital, but died about 36 hours after the crash. His last words where “Opfer müssen gebracht werden!” (Sacrifices need to be made!).

Dangers of the Atom

It is hard to underestimate the achievements of Marie Curie. She remains the only person to win a Nobel prize in two different sciences: in physics, for her work on radiation phenomena, and in chemistry, for the discovery of the elements radium and polonium. all of this took place during a time when women were discouraged or outright forbidden from doing academic science.

Her work with those radioactive elements was the cause of her death, considering that the dangers of ionizing radiation were not known at the time. She use to carry the test tubes with radioactive material in her pockets, without any safety measures. even today, her papers and even her cookbook are stored in shielded boxes because they are still highly radioactive. much of the money from the Nobel prize, as well as other monetary gifts she received, was given to friends and family and donated for research. Albert Einstein used to say that she was probably the only person who could not be corrupted by fame. Marie died from aplastic anemia caused by the long term radiation exposure on July 4th, 1934.

Submarine Innovator

Horace Lawson Hunley was a lawyer and a member of the Louisiana state legislature who developed early hand-powered submarines. Hunley understood how crucial the shipping trade with Europe was for the Confederacy, so he partnered with James McClintock and Baxter Watson to create an underwater vessel that would help keep the crucial shipping lanes with Europe open. three different models were created and built. Unfortunately, the third submarine sank, killing all eight crew members, including Hunley.

The vessel was recovered by the Confederacy, and on February 17th, 1864 it became the first successful combat submarine, sinking the USS Housatonic. The HL Hunley, as it was named, mysteriously disappeared after that mission, to be found over a century later in 1995. The crew received a proper burial only in 2004.

Walking on unknown Ground

Pushing out boundaries is the essence of science and invention. We don’t know enough about de Rozier’s death to say whether his devil-may-care attitude was responsible for his death — ballooning was in its infancy and is quite dependant on the wind — but it could have been. Lilienthal made over 2,000 similar flights before bad luck fatally caught up with him. Marie Curie, and the rest of science at the time, just didn’t know that radioactivity was dangerous. Hunley had no choice but to test out his submarine himself. all of them paid for their inventions with their lives.

We’re not saying that you shouldn’t wear glasses and hearing protection when operating an angle grinder. You must absolutely take every affordable safety precaution that you can. a lot of of us will never get near enough to the boundaries of the unknown that we’d need to take a leap like Lilienthal, much less do so thousands of times. Still, there’s a certain tragic nobility to these stories that underscores the strength of the desire to innovate, to be first, or to find something new.

WATER tank level METER prevents OVERFLOW

most of the homes in the area where [Raikut] lives have tanks on the roof to hold water. Each is filled from a well using a pump, with gravity serving as a way to pressurize the home’s water supply. The system isn’t automatic and requires the home owner to manually switch the pump on and off. [Raikut] made this process a lot easier by designing an LED bar indicator to monitor the water level.

The sensor is very simple. Each LED is basically its own circuit controlled by a transistor and a few resistors. A 5V signal is fed from 7805 linear regulator into the tank. The base of each transitor is connected to an insulated wire, each extending different depths in the tank. As the water rises it completes the circuit, illuminating the LED.

[Raikut] is conservation minded and built a buzzer circuit which is activated by the LED indicating the highest water level. If someone walks away from the pump switch while it’s filling the alarm will sound as it gets to the top and they can turn it off before it wastes water.

BUILDING A CMOS CLOCK ON A BREADBOARD

If you’re going to discover digital logic, why not goal high? That’s what [Easton] as well as his good friend did when they built a clock utilizing only 4000-series logic chips. On a breadboard, no less.

For a 1 Hz clock, [Easton] as well as his good friend utilized a 4060 counter paired with a flip flop. This counts off 59 seconds until, with the assist of an as well as gate, the seconds counter rolls over to zero. After repeating that once again for the minutes as well as building a similar circuit for the hour, as well as [Easton] had a working 4000-series 24-hour clock.

The breadboard clock may not be the prettiest thing, or a textbook example of exactly how to prototype circuits,  but that was fixed with [Easton]’s friend’s PCB design of a 12-hour clock. We couldn’t discover any type of pics of this, however we’re sure it’s awesome as well as a excellent method to discover about logic as well as design.

PREDATOR fit FOR MONSTERPALOOZA includes OVER-ENGINEERED shoulder CANNON

This Predator suit was premiered at this year’s Monsterpalooza conference. It’s nothing short of incredible. however the shoulder cannon is truly what caught our attention. The thing is completely motorized as well as includes noise as well as light firing effects.

We saw a glimpse of what [Jerome Kelty] is capable of about two years ago. He was showing off an Arduino-based animatronics platform he put together for a Predator shoulder cannon that tracked based on where the predator’s helmet was pointing. however other than a video presentation there wasn’t much information on the that actual build. This publish makes up for that as well as then some.

A replica of this high quality is seldom the work of just one person. A team of fans joined in to make it happen. After getting the molded parts for the backpack as well as canon from one more team member [Jerome] set out to in shape the support structure, motors, as well as manage electronics into the area available. That meant a ton of milling, cutting, as well as shaping parts like the support arm seen above which integrates a servo motor into its rectangular outline. all of the controls in shape in the backpack, with cable televisions running to the helmet, in addition to the cannon.

BUILDING A BENCH supply WITHOUT ALTERING THE ATX PSU

[FozzTexx] has been using a bench supply he made from an AT PSU for years. He put a lot of work into that one, removing unnecessary wires, mounting banana plug jacks on the metal case, and adding an on/off switch and labels. but if it ever dies on him it will be a major pain to do all that work again in order to replace it. When he set out to build another bench supply from an ATX PSU he decided to do so without altering the PSU. This way he can easily swap it out for a different one if he ever needs to.

The hardest part of the hack was sourcing connectors. but with the parts in hand he’s able to just plug the faceplate into the stock connector. This gives him access to all of the voltages, and provides an on/off switch and indicator light. He might also want to add the option of resetting the unit if the over-current protection kicks in.

VFD as well as NIXIE CLOCK TWOFER

often the stars line up as well as we get two somewhat similar develops hitting the Hackaday idea line at the exact same time. Recently, the develop of note was clocks utilizing some kind of screen tube, so right here we go.

First up is [Pyrofer]’s VFD network time clock (pic, above). The develop started as a vacuum flourescent screen tube he salvaged from an old fruit maker – whatever that is. The VFD was a 16 character, 14 section display, all managed by means of serial input.

The primary manage board is, of course, an Arduino with a WizNet 5100 Ethernet board. The clock links to the Web by means of DHCP so there’s no requirement to set an IP address. when connected, the clock sets itself by means of network time as well as screens the present date, time, as well as temperature supplied by a Dallas 1-wire temperature probe.

Next up is [Andrew]’s beautiful Nixie clock with sufficient LEDs to satiate the wishes of even the most discerning technophile. The board is based on a photo microcontroller with two changing power supplies – one for the 170VDC for the Nixies, as well as 5V for the rest of the board.

A battery backed DS1307 is the real-time clock for this board, as well as two MCP23017 I/O expanders are utilized to run the old-school Nixie drivers

All this is quite common for a Nixie clock build, if a bit excessive. It wasn’t sufficient for [Andrew], though: he utilized the USB support on his photo to throw a USB port on his board as well as composed an remarkable bit of software application for his PC to set the time, publish new firmware, as well as set the color fade as well as speed. With this lots of LEDs, it’s not something you want in your bedroom with all the lights on full blast, so he implemented a ‘sleep’ mode to turn off a lot of of the lights as well as all the Nixie tubes. It’s a excellent piece of work that might quickly be effectively funded on Kickstarter.

GLOWING EASTER EGGS much more fun THAN A dye task

This is a job to keep in mind for the youngsters next Easter. It utilizes electronics to illuminate your eggs instead of dying them (translated).

The job still has one foot in the old custom as it starts by blowing out the eggs. The larger hole on the bottom, which was utilized to evacuate the yoke an albumen, ends up being just the best size to insert an LED. You might just hook these as much as a battery as well as resistor, however [Rene] chose to add some performance by hiding an Arduino board in the fake turf of the Easter basket. This method the method the RGB LEDs can glow, blink, as well as rotate with different colors. as well as the foil covered chocolate bunnies aren’t just for show. He wired them as much as the I/O pins of the Arduino to utilize as a switch. When they’re both put on the exact same piece of foil it completes the circuit as well as starts the light show. See for yourself in the clip after the jump.

Of program for the older youngsters you’re going to requirement something much more challenging to keep their attention.

DUMPING SYNTH ROMS and avoiding BITROT

Bitrot is setting in, and our digital legacy is slowly turning to dust. efforts preserve our history are currently being embarked on many people around the Internet, and [Jason Scott] just got an automated CD ripper, so everything is kinda okay.

However, there is one medium that’s being overlooked. ROMs, and I don’t indicate video game cartridges. In the 80s, mask ROMs were everywhere, found in everything from talking cars to synthesizers.

[Ali] gotten a Korg i5m workstation from eBay a few years ago, but this unit had a problem. Luckily, he had a similar synth with the same samples stored on board. There was only one way to find out if bitrot was the cause: desoldering the chips and discarding all the information.

After fiddling around with his broken synth, [Ali] still had a problem with the sound output. deciding the ROM chips had to be the issue, [Ali] desoldered the chips and bought a breadboard SOP44 adapter after deciding soldering wires to each lead of the chip was a bad idea. This adapter was connected to an Arduino Mega — still the best tool for odd tasks like this — and the contents of the ROM were discarded to a PC with the help of a helpful Arduino sketch.

Dumping the ROMs took about 15 minutes, and that’s if he was able to maintain a good connection between the chip and Arduino for that long. [Ali] wrote an improved ROM reader after much trial and error, and was eventually able to get the same data out of the same chip eventually.

While the broken synth hasn’t been repaired yet, at least [Ali] has the crucial bits off of this antique instrument. That’s good enough for now, but [Ali] intends to take this project to completion and get those vintage samples playing out of this great old synth.

INTERNATIONAL OBFUSCATED C CODE contest WINNERS published

The worldwide Obfuscated C contest – the contest to produce the most useful, useless, or distinct program in absolutely unreadable C code – has just published the winners of the 2013 contest.

Of the entrances of note, a few truly stand out. The picture at the top of this post, for instance, comes courtesy of this submission. It’s an iterative ray tracer stuck inside an unlimited loop that, when left running overnight, is able to create fantastic renders.

An IOCCC contest wouldn’t be total without some ASCII art C code, as well as this entry fits the bill. It’s a Tetris painting tool that produces pictures constructed out of tetronomoes. Each picture is developed up one line each time from the bottom up, utilizing Tetris’ lack of physics to produce a photo out of un-cleared lines.

One of the most outstanding entrances for this (last?) year’s contest is a small 8086 PC emulator/virtual device written in only 4043 bytes of code. It’s a completely practical 80s-era PC emulator that can run vintage copies of AutoCAD, Windows, Lotus 1-2-3, as well as SimCity.

All the submissions are awesome, however like any type of IOCCC contest, there aren’t really any type of winners. Or they’re all winners. The Obfuscated guidelines aren’t extremely remove in that regard.

BENCH POWER supply RESETTING THINGY

As is common among some hackers, [Henry] re-purposed an ATX power supply unit to function as a bench power supply for testing circuits on a breadboard (much like this fancy example).

However, safety mechanisms on some modern PC PSUs do not automatically reset after over-current protection has kicked in, which soon became bothersome for [Henry]. In order to make his power supply more hacker-friendly, he wired up and programmed an ATtiny85V, using some Arduino libraries, to do that for him. This simple project is a terrific example of using a hack to improve a pre-existing hack.
