Making a Unicorn HAT

via Raspberry Pi

Our good friends at Pimoroni have made a very sparkly HAT. We thought you’d like to see where unicorns come from.

The Unicorn HAT is available at Pimoroni for £24 – get them while they’re warm (but not hot)! Clive’s busy writing a graphics resource for learners featuring this particular HAT – watch this space for more details.

An SDK for the ESP8266 WiFi Chip

via Hackaday » » hardware

ESP The ESP8266 is a chip that turned a lot of heads recently, stuffing a WiFi radio, TCP/IP stack, and all the required bits to get a microcontroller on the Internet into a tiny, $5 module. It’s an interesting chip, not only because it’s a UART to WiFi module, allowing nearly anything to get on the Internet for $5, but because there’s a user-programmable microcontroller in this board. If only we had an SDK or a few libraries…

The ESP8266 SDK is finally here. A complete SDK for the ESP8266 was just posted to the Expressif forums, along with a VirtualBox image with Ubuntu that includes GCC for the LX106 core used in this module.

Included in the SDK are sources for an SSL, JSON, and lwIP library, making this a solution for pretty much everything you would need to do with an Internet of Things thing. As far as LX106 core is concerned, there’s example code for using the spare pins on this board as GPIOs, I2C and SPI busses, and a UART.

This turns the ESP8266 into something much better than a UART to WiFi module; now you can create a Internet of Things thing with just $5 in hardware. We’d love to see some examples, so put those up on and send them in to the tip line.

FTDI Screws Up, Backs Down

via Hackaday » » hardware


A few days ago we learned chip maker FTDI was doing some rather shady things with a new driver released on Windows Update. The new driver worked perfectly for real FTDI chips, but for counterfeit chips – and there are a lot of them – the USB PID was set to 0, rendering them inoperable with any computer. Now, a few days later, we know exactly what happened, and FTDI is backing down; the driver has been removed from Windows Update, and an updated driver will be released next week. A PC won’t be able to communicate with a counterfeit chip with the new driver, but at least it won’t soft-brick the chip.

Microsoft has since released a statement and rolled back two versions of the FTDI driver to prevent counterfeit chips from being bricked. The affected versions of the FTDI driver are 2.11.0 and 2.12.0, released on August 26, 2014. The latest version of the driver that does not have this chip bricking functionality is, released on January 27th. If you’re affected by the latest driver, rolling back the driver through the Device Manager to will prevent counterfeit chips from being bricked. You might want to find a copy of the 2.10.0 driver; this will likely be the last version of the FTDI driver to work with counterfeit chips.

Thanks to the efforts of [marcan] over on the EEVblog forums, we know exactly how the earlier FTDI driver worked to brick counterfeit devices:


[marcan] disassembled the FTDI driver and found the source of the brick and some clever coding. The coding exploits  differences found in the silicon of counterfeit chips compared to the legit ones. In the small snippet of code decompiled by [marcan], the FTDI driver does nothing for legit chips, but writes 0 and value to make the EEPROM checksum match to counterfeit chips. It’s an extremely clever bit of code, but also clear evidence FTDI is intentionally bricking counterfeit devices.

A new FTDI driver, presumably one that will tell you a chip is fake without bricking it, will be released next week. While not an ideal outcome for everyone, at least the problem of drivers intentionally bricking devices is behind us.

FTDI Drivers and Counterfeit Chips

via SparkFun Electronics Blog Posts

As you may or may not have heard by now, the latest driver update from chip manufacturer FTDI is disabling, semi-permanently, counterfeited chips. I’ll get more into the technical details later, but I’m going to open with this:

At this time, SparkFun does not believe any of our products to be compromised by this issue.

The FT232

Why does this matter so much? Well, the FTDI USB-to-Serial bridge IC (the FT232, specifically) has been a mainstay of the hardware hacking community for many years. The first USB-based Arduino boards used it; SparkFun’s RedBoard still does.

As soon as we heard about it (from Twitter, of course), we immediately began assessing our product line for products which might be of concern. At the moment, we have about 30 individual products using the FT232 chip. We immediately crossed most of them off the list; our in-house assemblies are all produced using chips from reputable suppliers (like Mouser, Digikey, Future, etc.).

We have less visibility into assemblies that come pre-made to us, however, so we immediately set about testing them for vulnerability to this change. Testing is still ongoing, but our preliminary tests show that current stock is not affected. We already had the discussion with suppliers in the past regarding counterfeit chips (you may recall that we had a brush with this issue in the past), so we’re quite confident in the product we’re currently selling.

If you think something you purchased from SparkFun is affected by this please contact our tech support team immediately. They’re really good at what they do, and they’ll get your problem sorted out in no time.

Okay, now that we’ve covered the business end, let’s talk nerdy.

From what we’ve been able to glean from other posts (as yet, we’ve not been able to duplicate this in house, since we don’t have any counterfeit FTDI chips), this is an intentional attempt by FTDI to address the growing population of counterfeit FTDI chips on the world market. With the release of Windows driver version on 26 August, a part of the driver’s functionality is to silently change the PID (which is the 16-bit code assigned to a product by its manufacturer to allow the OS to identify the driver which should be used for that part) from 0x6001 to 0x0000.

This change takes place in the target’s non-volatile memory, so even after the counterfeit device is removed from the system which altered it, that chip will no longer be recognized as an FTDI-compatible USB to serial bridge, on any computer, under any operating system.

Of course, it may be possible to change the PID back, but any Windows computer with v2.12.0.0 of the driver installed will immediately alter the PID again.

The reason this has become an issue recently (remember, the date on this driver is 26 August) is because the new driver recently hit Windows update. Anyone who’s used FTDI chips extensively under Windows has probably experienced the COM port proliferation issue: whenever an FTDI chip is plugged into a USB port that it’s not been plugged into before, Windows searches Windows Update for a new driver and assigns a new COM port number to that chip on that USB port. If you don’t tell Windows to stop looking online, it will automatically and silently load the new driver which will automatically and silently brick the counterfeit FTDI chips.

I haven’t heard anything suggesting Mac or Linux drivers have a similar function, although if they don’t now it’ll only be a matter of time until they do. It’s unclear at this time how the FTDI driver identifies counterfeit chips; until we know more about that process, if you think you may have received counterfeit parts (say, as a part of a knock-off Arduino clone purchased on Ebay at a suspiciously low price), avoiding updating your drivers is probably a wise thing to do.

Keep an eye on this post and the SparkFun (or SFE_Engineering) Twitter accounts; if we find out anything new we’ll update this post. I’ll be trying to find a non-destructive means for identifying the counterfeits, and if I don’t and someone else does, we’ll post it here.

Robot volcanology

via Raspberry Pi

Earlier this week, we talked about Raspberry Pi robots under the sofa. Today, we’ve got a Raspberry Pi robot under a volcano to show you.


Dr Carolyn Parcheta studied volcanology in Hawaii, and now works as a NASA postdoctoral fellow in Pasadena. Her particular area of study is the geometry of volcanic fissure vents: something that’s very hard to map, because they’re inaccessibly narrow, coated with sharp glass from eruptions, and are often destroyed when magma flows through them.

Learning about that geometry is crucial in building an understanding of how eruptions work: how magma flows, and how gas escapes. So with the help of a Raspberry Pi, Dr Parcheta has built a wall-climbing robot to go where humans can’t, and is using it to model cracks and vents in much more detail than has been possible before.

She made this video about the project for a National Geographic award last month, where she placed in the finals.

Dr Parcheta’s eventual goal is to 3d-map all of the fissures in Kilauea, an active volcano on Hawaii. There are 54 in all, and she completed maps of two in May this year. We’ll be keeping an eye on her progress – and on the progress of that brave little robot!

The Internet of Things

via Nuts and Volts

Since the birth of the Internet, there has been talk of total connectivity — between people, people and their possessions, and things to things. Up until recently, the reality has been that such ecosystems existed only in academic and corporate research centers. Today, the Internet of Things (IoT) is a practical reality in many settings.

Watch That Windows Update: FTDI Drivers Are Killing Fake Chips

via Hackaday » » hardware


The FTDI FT232 chip is found in thousands of electronic baubles, from Arduinos to test equipment, and more than a few bits of consumer electronics. It’s a simple chip, converting USB to a serial port, but very useful and probably one of the most cloned pieces of silicon on Earth. Thanks to a recent Windows update, all those fake FTDI chips are at risk of being bricked. This isn’t a case where fake FTDI chips won’t work if plugged into a machine running the newest FTDI driver; the latest driver bricks the fake chips, rendering them inoperable with any computer.

Reports of problems with FTDI chips surfaced early this month, with an explanation of the behavior showing up in an EEVblog forum thread. The new driver for these chips from FTDI, delivered through a recent Windows update, reprograms the USB PID to 0, something Windows, Linux, and OS X don’t like. This renders the chip inaccessible from any OS, effectively bricking any device that happens to have one of these fake FTDI serial chips.

Because the FTDI USB to UART chip is so incredibly common,  the market is flooded with clones and counterfeits. it’s very hard to tell the difference between the real and fake versions by looking at the package, but a look at the silicon reveals vast differences. The new driver for the FT232 exploits these differences, reprogramming it so it won’t work with existing drivers. It’s a bold strategy to cut down on silicon counterfeiters on the part of FTDI. A reasonable company would go after the manufacturers of fake chips, not the consumers who are most likely unaware they have a fake chip.

The workaround for this driver update is to download the FT232 config tool from the FTDI website on a WinXP or Linux box, change the PID of the fake chip, and never using the new driver on a modern Windows system. There will surely be an automated tool to fix these chips automatically, but until then, take a good look at what Windows Update is installing – it’s very hard to tell if your devices have a fake FTDI chip by just looking at them.

Experience sound multi-sensorially with Ocho Tonos

via Arduino Blog


Some of you may have noticed that words like rhythm, texture, pattern, can be used both to describe fabrics, as well as sound. Focused on building an interface as a whole, using mostly textiles, OCHO TONOS invites the user to interact through touch, and experience sound in a multi-sensorial way. Ocho Tonos is an interactive installation by EJTech duo (Esteban de la Torre and Judit Eszter Kárpáti) I met last July during etextile summer camp while they were working on this experimental textile interface for tactile/sonic interaction by means of tangibles:

Exploring the relation between sound and textile and experimenting with the boundaries of our senses whilst changing the way we perceive fabric, surfaces and their manifestation as sound. Recontextualizing our tactile interaction with textile acting as an interface, where each element triggers, affects and modifies the generated sound’s properties. Creating a soundscape through sensor technology enticing audiophiles to interact and explore with reactive textile elements.The nexus of the body, the senses and technology.
OCHO TONOS is a symbiosis of the unique hand-crafted traditional textile techniques and the immaterial digital media.

Thanks to Arduino Mega ADK , all inputs coming from the touch of the user on the soft sensors are translated into a digital platform, parsed and filtered through MaxMSP, in order to control the generation of a soundscape in Ableton Live.

Ocho Tonos was chopped, spiced and cooked at Kitchen Budapest. Sounds used are samples from the working machinery at  TextielLab.
