Future Tech And Upgrading Your Brain

hackingNPhilDec

A few weeks ago [Jacob Merz] sent me an email about his sensory expansion project, which allows the wearer to “hear” infrared light by mapping it to specific tones. Although a rough prototype, [Jacob’s] device reflects a larger realm of technological possibilities: the development of a type of “peripheral” for the human body. EDIT: Updated gallery to include new photos and added link to Jacob’s new site.

You’re going to want to listen to [David Eagleman’s] TEDx Alamo talk particularly around 10 minutes in, where he talks about the sonic glasses.  [Eagleman] claims that the human brain, if given a consistent input that corresponds to the real world, can decipher the signal into usable information. The sonic glasses, which provide a type of sonar to the blind wearer, eventually just…work. Your brain can “learn” its own drivers for input devices.

Hackaday Links: December 8, 2013

Let’s start off with some high voltage. Here’s a sweet Jacob’s Ladder build from [Robert]. The site hosting his short writeup has been up and down for us so here’s a cache link.

Speaking of high voltage, if you want to switch mains with your project [Tom] has a breakout board for cheap mechanical relays. [via Dangerous Prototypes]

[Dario] made his own version of an electronic Advent calendar [translated]. There are no numbers, you must solve the mystery of the flashing LEDs to figure out which package goes with each day.

If you ever work with lighted arcade buttons here’s a guide for swapping out the light for an RGB LED. This hack uses through-hole LEDs. We’ve actually seen a surface mount hack that includes a PCB to mimic the old bulbs.

Next time you stay overnight at an event you can give yourself the best view in the campground. This tiny little camper was mounted on a scissor lift! That first step on the way to the Porta Potty is a doozy! [via Adafruit]

[Žiga] was nice enough to demonstrate this smart-watch hack by displaying our name and logo (we love pandering!). It features the MSP-WDS430 which is a surprisingly stylish offering from Texas Instruments. In addition to analog clock hands it has an OLED display driven by the MSP430 inside.

Here’s a quick PIC-based metal detector which [Nicholas] built.

And finally, [Chet] saw the oil tank level sensor we featured this week. He built a nearly identical system earlier this year. The oil level sensor works in conjunction with the custom thermostat he built around an Android tablet.

Fail Of The Week: Hackaday Writer’s First CNC Adventure

This Fail of the Week post focuses on a project from [Limkpin] aka [Mathieu Stephan], one of the Hackaday contributors. He wanted a CNC mill of his very own and decided to go with a kit that you assemble yourself. If it had been clear sailing we wouldn’t be talking about it here. Unfortunately he was met with a multitude of fails during his adventure. We’ll cover the highlights below.

Retrotechtacular: An Ax Factory Of Yore

When your mind’s eye thinks of an ax factory you may envision workers loading blanks into a machine that refines the shape and profile before heading to an annealing furnace. But this is Retrotechtacular, and we’re tickled to feature a look at a different time in manufacturing history. This ax factory tour looks at every step in the manufacturing process at a factory in Oakland, Maine. It was shot on film in 1965 just a few months before the factory shut down. [Peter Vogt] did a great job of shooting and editing the reel, and an equally fine job of converting it to digital so that we can enjoy it on his YouTube channel.

Above you can see the automatic hammer — known as a trip hammer — that is driven by cam action. At this point a lot of work has already been done. Blanks were cut from steel bars by two workers. These were shaped on the trip hammer before being bent in half to create the loop for the ax handle. From there a piece of high-carbon steel was added to form the cutting surface. This brings us to the step above, shaping the two glowing-hot pieces into one.

We don’t want to undermine the level of craftsmanship, and the labor-intensive process shown off here. But we can’t end this write-up without at least mentioning the kitsch that is smoking cigarettes and pipes on the job. At one point a worker actually lights his pipe using a the glowing-hot ax head.

To give you an idea of how this contrasts with modern manufacturing, here’s a How It’s Made episode on axes (although we think whats being made would more appropriately be called hatchets).

Hacking And Philosophy: Crackdown Part IV

h&pcrackdown4

This week we conclude our discussion of The Hacker Crackdown with the final chapter, which covers the rise of the EFF. In early 1990, the idea of civil liberties online was little more than a notion in [John Barlow’s] head, but by the end of the same year, the EFF had formed to not only keep Phrack editor [Knight Lightning] out of prison, but to also successfully challenge the Secret Service on behalf on Steve Jackson Games.

[Sterling] details [Knight Lightning’s] trial in this chapter and it’s worth reading. Had the EFF lost the case, online publications would have suffered serious setbacks in terms of freedom of speech, and sites like ours would likely be considered illegal. Read on, dear reader.

Hackaday Links: December 1, 2013

Since our ‘ol buddy [Caleb] left Hackaday for EE Times, he’s been very busy. One of his latest projects is doing Antique Electronics Autopsies. This time around it’s a 1953 Heathkit Grid Dip Meter. It’s a beautiful piece of engineering with Point to Point wiring and metal gears.

We love microcontroller breakout boards, and so does [Tim] apparently. He built a breadboard friendly breakout for the NXP LPC812. It’s an ARM Cortex M0+ with 16kb of Flash and 4kb of SRAM. The entire breakout board is smaller than the through-hole DIP LPC1114. When are we going to see these on Tindie, [Tim]? Here’s the Git with the board files. You can also pick up a board at OSH Park – $3.30 for a set of three.

What do you do when you have the perfect idea for a Kickstarter, but don’t have the funds for the perfect sales pitch? The obvious solution is to start an Indiegogo campaign to raise funds for your Kickstarter. Unfortunately, this campaign has already been successfully funded, so it’s already too late to get in on the ground floor. Relevant xkcd.

We’ve seen this DIY cell phone before but now it’s just about ready for production. [David] at the MIT Media Lab has been working on a bare-bones, ATMega & GSM module phone for a while now, and now you can grab the firmware and board files. Make your own cell phone!

Here comes Hanukkah, so drink your gin and tonica. Here’s a pedal powered menorahica so put on your yarmulke, it’s time to celebrate Hanukkah.

Fail Of The Week: How A Cheap USB AC Adapter Might Indirectly Burn Your House Down

This Fail of the Week will remind our readers that every project they make, no matter how small they might be, may have big consequences if something goes wrong. Shown in the picture above is an oven that [Kevin] tweaked to perform reflow soldering. The story is he had just moved into a new place a few weeks ago and needed to make a new batch of boards. As he had cycled this oven many times, he was confident enough to leave the room to answer a few emails. A few minutes later, he had the unfortunate experience of smelling something burning as well as discovering white smoke invading his place.
