So you want to photograph Eclipse 2017 but you don’t want to rush out and buy an expensive DSLR just for the event? Not a problem, if you build this simple smartphone filter and occluder.
It all started innocently enough for [Paul Bryson] with his iPhone and a lens from those cheap cardboard eclipse glasses we’re starting to see everywhere. Thinking that just taping the filter over the stock lens would do, [Paul] got a painful faceful of sunshine when he tried framing a shot. Turns out the phone body was not big enough to blot out the sun, and besides, the stock lens doesn’t exactly make for a great shot. So with an iPhone telephoto lens affixed to a scrap of wood and a properly positioned filter, [Paul] has a simple rig that’ll let him get some great pre-totality shots of the eclipse, and it’ll be easy to bust out the phone for two minutes of totality selfies. Looks like this setup would be easy to adapt to other phones, too.
We’re all over Eclipse 2017, from Hackaday Eclipse Meetups in at least four different points along the path of totality to experiments on relativity to citizen science efforts so you can get in on the action too. Mark your calendars – August 21 will be here before you know it.
Voice-based assistants are becoming more common on devices these days. Siri is known for being particularly good at responding to natural language and snarky responses. In comparison, Google’s Assistant is only capable of the most obvious commands, and this writer isn’t even sure Microsoft’s Cortana can understand English at all. So it makes sense then, if you want voice control for your PC, to choose Siri as your weapon of choice. [Sanjeet] is here to help, enabling Siri to control a PC through Python.
The first step is hooking up the iPhone’s Notes app to a Gmail account. [Sanjeet] suggests using a separate account for security reasons, as you’ll need to place the username and password in a Python script. The Python script checks the Gmail account every second, looking for new Notes from the iPhone. Then, it’s as simple as telling Siri to make a Note (for example, “Siri, Note shutdown”) and the Python script can then pick up the command, and act accordingly.
It’s a quick and easy way to get Siri to do your bidding. There’s other fancy ways to do it, too — like capturing Siri’s WiFi data on your home network.
[Scotty Allen] from Strange Parts, has just concluded a three month journey of what clearly is one of the most interesting Shenzhen market projects we have seen in a while. We have all heard amazing tales, pertaining the versatility of these Chinese markets and the multitude of parts, tools and expertise available at your disposal. But how far can you really go and what’s the most outrageous project can you complete if you so wished? To answer this question, [Scotty] decided to source and assemble his own Iphone 6S, right down to the component level!
The journey began by acquiring the vehemently advertised, uni-body aluminium back, that clearly does not command the same level of regard on these Chinese markets when compared to Apple’s advertisements. [Scotty’s] vlog shows a vast amount of such backings tossed as piles in the streets of Shenzhen. After buying the right one, he needed to get it laser etched with all the relevant US variant markings. This is obviously not a problem when the etching shop is conveniently situated a stones throw away, rather simplistically beneath a deck of stairs.
Next came the screen assembly, which to stay true to the original cause was purchased individually in the form of a digitizer, the LCD, back-light and later casually assembled in another shop, quicker than it would take you to put on that clean room Coverall, you thought was needed to complete such a job.
[Scotty] reports that sourcing and assembling the Logic board proved to be the hardest part of this challenge. Even though, he successfully purchased an unpopulated PCB and all the Silicon; soldering them successfully proved to be a dead end and instead for now, he purchased a used Logic board. We feel this should be absolutely conquerable if you possessed the right tools and experience.
All the other bolts and whistles were acquired as separate components and the final result is largely indistinguishable from the genuine article, but costs only $300. This is not surprising as Apple’s notorious markup has been previously uncovered in various teardowns.
Check out [Scotty’s] full video that includes a lot of insight into these enigmatic Shenzhen Markets. We sure loved every bit of it. Now that’s one way get a bargain!

There’s something to be said for economies of scale and few things sell more than cell phones. Maybe that’s why [NODE] took inspiration from an iPhone slide out keyboard case to create this Pi Zero W-based portable terminal. This is actually his third iteration, and in the video below he explains why he has built the new version.
By housing the custom bits in a 3D-printed frame that is size compatible with the iPhone, [NODE] manages to leverage the slick slide out keyboard cases available for the phone. The iPhone in question is an older iPhone 5, so the cases are inexpensive, compared to the latest generation. On the other hand, the iPhone 5 is recent enough that it shouldn’t be hard to find a compatible case.
The circuitry itself is pretty straightforward: a battery, a charge controller, and an LCD display. The only complaint we could see was the lack of a control key on the keyboard.

I’ll admit it. I can be a little cheap. I also find it hard to pass up a bargain. So when I saw a robot kit at the local store that had been originally $125 marked down to $20, I had to bite. There was only one problem. After I got the thing home, I found they expected you to supply your own radio control transmitter and receiver.
Normally, that wouldn’t be a problem but lately… let’s just say a lot of my stuff is in storage and I didn’t have anything handy. I certainly didn’t want to go buy something that would double the cost of this robot that I really didn’t need to begin with.
However, I did have a few ESP8266 modules handy. Good ones, too, from Adafruit with selected 5 V I/O compatibility and an onboard regulator. I started thinking about writing something for the ESP8266 to pick up data from, say, a UDP packet and converting it into RC servo commands.
Seemed like a fair amount of work and then I remembered that I wanted to try Blynk. If you haven’t heard of Blynk, it is a user interface for Android and Apple phones that can send commands to an embedded system over the Internet. You usually think of using Blynk with an Arduino, but you can also program the embedded part directly on an ESP8266. I quickly threw together a little prototype joystick.

Ever so slowly, the main storage in our computers has been moving from spinning disks, to SSDs over SATA, to Flash drives connected to a PCI something or other. The lastest technology is NVMe — Non-Volitile Memory Express — a horribly named technology that puts a memory controller right on the chip. Intel has a PCI-based NVMe drive out, Samsung recently released an M.2 NVMe drive, and the iPhone 6S and 6S Plus are built around this storage technology.
New chips demand a reverse engineering session, and that’s exactly what [Ramtin Amin] did. He took a few of these chips out of an iPhone, created a board that will read them, and managed to analize the firmware.
Any reverse engineering will begin with desoldering the chip. This is easy enough, with the real trick being getting it working again outside whatever system it was removed from. For this, [Ramtin] built his own PCIe card with a ZIF socket. This socket was custom-made, but the good news is you can buy one from ITEAD. Yes, it is expensive — that’s what you get with a custom-made ZIF socket.
With the chip extracted, a custom PCIe card, and a bit of work with the NVMe implementation for Linux, [Ramtin] had just about everything working. Eventually, he was able to dump the entire file system on the chip, allowing anyone to theoretically back up the data on their iPhone or MacBook Air. Of course, and especially for the iPhone, this data is encrypted. It’s not possible to clone an iPhone using this method, but it is a remarkably deep dive into the hardware that makes our storage tick.”
Once again, [Rulof]’s putting his considerable hacking abilities to good use, his good use that is. By modding a few simple parts he’s put together something that he can carry around on his keychain that’ll allow him to steal power from his friend’s phones to charge his own phone.
He starts by cutting away the motor from an iPhone fan to isolate the Micro USB connector. He then removes the charging circuit board from a cheap Chinese USB power bank, and solders wires from the Micro USB connector to one side of the board. Lastly, he cuts away the Lightning connector from a Lightning-to-USB cable and solders that connector to the other side of the circuit board. For longevity and cosmetics, he puts it all in a small wood block and connects a key ring. The result is a small, neat looking box with a Micro USB connector on one side and a Lightning connector on the other. You can see him make it, and then use it to steal power from his friends in the video after the break.
