Hackaday Links: January 10, 2016

Everybody loves cheap stuff, and we hate telling everyone about coupon codes. That said, TI has a new LaunchPad development board they’re promoting. It’s based on the MSP432, the ARM extension of their MSP430 line. The MSP432 is an ARM Cortex M4F, low power, and planned for production later this year.

Here’s your daily CES garbage post. Through a collaboration between Sony and Nissan, a car has become a video game controller controller. A controller plugs into the ODB II port, reads throttle, brake, and steering wheel positions (and buttons on the dash/steering wheel, I guess), and translates that into controller input for a PlayStation 4. What games do they play with a car? You would think Gran Turismo, Rocket League, or other games with cars in them. Nope. Football.

Dangerous Prototypes is a legal Chinese company! [Ian] didn’t say anything about the process about becoming a legal Chinese company because he wrote a blog post, not a book. Shenzhen Dangerous Prototypes Electronics Technology Limited allows them to have an office in the Shenzhen electronics market, hire local and foreign hackers, host Hacker Camp Shenzhen, and allow people to apply for ‘Authorized Authority’ visa letters for the people who need them. Great news for a great company.

The Forge hackerspace in Greensboro, NC is growing. In just over a year they have 160 members and they’ve already outgrown their 3,400 square foot space. Now they’re moving to a larger space that’s twice the size and they’re looking for donations.

People have been taking old iPad screens and turning them into HDMI displays for years now. [Dave] got his mitts on a panel from a Macbook Pro 17″, and turned it into a monitor. It required a $50 LVDS adapter, but the end result is great – a 1920×1200 panel that looks pretty good.

Crowdsourcing Reference Designs from Github

A ton of open source hardware projects make their way onto Github, and Eagle is one of the most popular tools for these designs. [TomKeddie] came up with the idea of searching Github for Eagle files containing specific parts at Hacker Camp Shenzhen, and a method of scraping useful ones.

The folks over at Dangerous Prototypes used this to build the Github Hardware Search tool. Simply enter a part number, like “ATmega328P”, and you’ll receive a list of the designs using that part. You can then study the design and use it as a reference for your own project. You can also snag library files for the parts.

Of course, there are some limitations to this. The most obvious one is the lack of quality control. There’s no guarantee that the design you find works, or has even been built. Also, it only works for Eagle 6+ files, since prior versions were not XML. You can read more about the design of the tool over on Dangerous Prototypes.

Hackaday Links: September 13, 2015

One more go at new enclosures for the Amiga 1200. Yes, it’s a Kickstarter campaign, and we mentioned a similar the same campaign last month. The previous campaign received a little more than half of the desired funding in a 30-day campaign. The new campaign received half its funding in a week. The only difference? Now you can put a Raspberry Pi in a newly manufactured A1200 case. And they say Raspberry Pi consumerism isn’t a thing…

Cheap SLA printing service. [Ian] and Dangerous Prototypes have made a name for themselves with dirt cheap, acceptable quality PCBs. Now they’re going for custom prints on a resin machine. It’s $0.95 per gram (density is 1.3g/cc). That’s cheap.

[James Willis] built a floppy drive orchestra. There are 16 drives in this orchestra, all controlled by an FPGA. Here’s the writeup.

Here’s a video overview of a real, huge, rideable hexapod robot. ‘Wow’ is just about the only thing we got for this.

Western Digital introduced a hard drive made specifically for the Raspberry Pi. It’s a hard drive with a USB interface, and a USB cable that connects to the Pi, the drive, and a power adapter. In other news, externally powered USB hard drives exist. You can buy a 2TB drive for the price of the 1TB PiDrive. What was that thing about Raspi consumerism?

Next week is the Open Hardware Summit in Philadelphia. We’ll be there (or rather, I will). We’ll have a post on the OHS badge up on Monday. Would anyone like to go see the lady made out of soap? It’s right around the corner from the venue.

Caption CERN Contest – Not your father’s POV Display

Accidents happen – but the awesome quotes you all sent in for Week 15 of the Caption CERN Contest were no accident. A huge thank you for our biggest week yet! The scientists in this week’s image are definitely cleaning up after some type of nasty accident. At first blush it looks like an electrical problem in the coils of what appears to be part of a beam line. With all that soot and radiation dangers to boot, only the photographer and the people in the image know for sure!

The Funnies:

  • “This is the second server these idiots have fried! What the hell’s a Hulu, and why are they trying to watch Gilligan’s Island with it?” Thanks to some unplanned quantum tunneling, Berners-Lee was even further ahead of his time than he thought” – [The Green Gentleman] (Two weeks in a row!)
  • “I found the bug. Who gets to tell Joe he’s sterile?”- [jonsmirl]
  • “‘I told the Captain that she couldn’t take any more’ – Scotty” – [md_reeves]

The winner for this week is [Mr. mmWave] himself, [Tony Long] with “Hardware Accelerator moto – Fail Fast, Fail Often. Also applies to Accelerator Hardware.” [Tony] will be debugging his next microwave mm band ham radio with a Logic Pirate From The Hackaday Store! Congratulations [Tony]!

Week 16: This is not your father’s POV Display!

cern-16-smScientists at CERN have come up with some amazing science advancements. They’ve also needed ways to display the data they collect. This image may depict some incredible new way to display data collected from a high power physics experiment – or it could be a scientist’s project for the CERN science fair. We may never know.

The album is titled CHAMBRE A ETINCELLES DANS EXPO TECHNOL, which roughly translates to “Sparks in the technology expo room”. The lines traveling between the three horizontal display devices definitely appear to be aligned. Are they sparks of electricity? You tell us!

buspirate2Last week’s prize was a Logic Pirate. This week we’re giving away a Bus Pirate from The Hackaday Store.

Add your humorous caption as a comment to this project log. Make sure you’re commenting on this contest log, not on the contest itself.

As always, if you actually have information about the image or the people in it, let CERN know on the original image discussion page.

Good Luck!

CAPTION CERN CONTEST – Accidents Happen

Week 14’s image may have had us at a loss for words, but it definitely didn’t slow down the intrepid caption contest entrants on Hackaday.io! Thanks to everyone who entered. We still have no idea what that device is, though we are sure that we wouldn’t want to be standing under it. Just look at those 4×4 sections of lumber holding everything up. What’s the French translation for “sketchy as hell”? The device definitely includes a pressure or vacuum vessel of some sort. Beyond that, your guess is as good as ours. We’ll keep an eye on CERN’s image discussion page in case an answer does pop up.

The Funnies:

  • “Damn it Athol, stop harping about protocol and hand me the duck tape. This is nuclear physics, not rocket science!” – [The Green Gentleman]
  • “This will mix a mean Margarita for the party tomorrow, I promise you!.”- [Mats L]
  • “To long have we tried to smash particles, now we will blend them.” – [paul]

The winner for this week is [LongHairedHacker] with: “After weeks of complicated assembly the team finally found out that the IKEA Årc, was in fact not a fusion reactor. It did make a hell of an espresso though.”

As promised, [LongHairedHacker] will be taking home a Bus Pirate From The Hackaday Store!Congratulations!

Week 15

cern-15-smAccidents happen! When you’re working on the bleeding edge of science and technology, things don’t always go as planned. In this image, we’re looking at what appears to be the result of some sort of failure. We’re not sure what the piece of equipment was, but “was” is the proper term – as it’s now charred to a crisp.

The two scientists investigating the damage don’t seem to be worried about the radiation warning posted on the end of the machine’s aperture. Hopefully they know what they’re doing! 

Last week’s prize was a Bus Pirate. This week we’re giving away another Dangerous Prototypes design, a Logic Pirate from The Hackaday Store.

Learning I2C with the Bus Pirate

When an air quality display project needed a display, [Inderpreet] looked into small character-based LCDs. [Inderpreet’s] chosen LCD used an I2C interface, which was new to him. Rather than shy away, [Inderpreet] grabbed his Bus Pirate and dove in!

I2C or Inter-Integrated Circuit serial interfaces are often mentioned here on Hackaday. They generally are easy to use, but as with all things, there are little gotchas which can make the road a bit more bumpy the first time you travel it. One of those things is voltage interfacing – I2C uses bidirectional open drain lines, so interfacing 3.3 V and 5V circuits requires a voltage level shifter circuit designed to handle that requirement. Thankfully in [Inderpreet’s] case, both his TI launchpad target devboard and the LCD used 3.3 volt logic levels.

buspirate2Before using the TI though, [Inderpreet] wanted to test with the Bus Pirate first. This would allow him to verify the hardware, and to make sure he was correctly using the I2C bus. The Bus Pirate can operate at 3.3V or 5V logic levels, and has on-board programming specific to the I2C bus. Controlling the Bus Pirate is as easy as hooking up a serial terminal program and plugging in a USB cable.

The I2C bus protocol is relatively simple, but can still be confusing to a new user. Each transaction needs an address, read/write bit, and a start command sent in the proper sequence before the data bytes can begin flowing. There are also acknowledge bits which prove that the data bytes are actually being received by the LCD. The Bus Pirate made all this easy, allowing [Inderpreet] to quickly display “Hello” on his LCD module.

The I2C bus is just the tip of the iceberg for the Bus Pirate. If you’re interested in learning more, check it out over at The Hackaday Store!

The Joys Of Shipping From China

A few months ago, news of a new PCB fab service headed up by [Ian] over at Dangerous Prototypes leaked onto the Internet. It’s extremely cheap – $14 USD for a 5cm square board with free worldwide shipping. [Ian] admits the boards aren’t the greatest quality, that’s not the point; the site’s motto is simply, ‘No bull, just crappy PCBs.’

What began as an internal website to handle all of DP’s PCB orders was now on the Internet, and orders were flying in. At first, shipping a few dozen PCBs around the globe every week was easy, but since Dirty PCBs hit the big time, customers rightfully or not, started freaking out because of the oddities of Chinese shipping and logistics companies.

[Ian] is using Espeed Post for all their shipping, and if you’ve ever ordered anything from China off of Ebay, it’s possible you’ve had something shipped through Espeed before. Because of the oddities of shipping, and the fact that Shenzhen and Hong Kong are right next to each other, even the people at Dangerous Prototypes don’t know which countries your PCBs will go through on the trip from the fab house to your front door. This has caused much consternation with DirtyPCB customers that don’t seem to realize they’re getting custom PCBs for under two dollars a board, shipped to them across the world in a week for free. Some people’s children, huh?

Things get significantly, ahem, dirtier, when Chinese holidays are taken into account. China has a lot of them, and they’re long. They’re just wrapping up the National Day holiday, 10 days in the first week of October. Everyone is backlogged, and the China/Hong Kong border is the mess of trucks seen above.

If a holiday isn’t bad enough, the new President of China is cracking down on corruption. 500 officials were fired at the largest land border with Hong Kong, due in no small part to vans full of meth and tons of counterfeit currency. Every package leaving China is inspected individually, and shipping times have exploded.

To deal with this, Dangerous Prototypes has posted a big red warning on the dirtypcb site, but experience in dealing with people on the Internet tells them this won’t be a viable solution. They’re now dealing directly with DHL, and are apparently getting priority clearance through customs. It’s not fun, as DP will now have to figure out how to work with DHL’s API. It’s a lot of work and a lot of trouble, but DP still has a few tricks up their sleeve – they’re working on an online schematic entry and PCB layout site and the extremely interesting DirtyCables – custom cables shipped to your door.
