Now There’s USB-C On The IPhone SE

July 22, 2022 by 37 Comments

As confusing as it can be, USB-C is actually pretty good, and certainly has its fans. [David Buchanan] must be one of them, for he did a great job putting a USB-C port into his iPhone SE.

[David] didn’t want to ruin a pristine example, so set about hacking the cheapest first-gen iPhone SE he could find on eBay. His approach was simple: get a USB-C to Lightning dongle and hack it into the phone’s body.

The first step was to strip the adapter down and melt off the Lightning connector. He then de-soldered the Lightning port from the phone, and found a bunch of test pads on the motherboard corresponding to its pins. Soldering leads from the adapter to the test pads got things up and running, once he properly hooked up a connection-detect pin to ground.

With a bit more trimming, some hot glue and some enameled wire, [David] was able to cram everything inside the iPhone. Paired with a new screen and home button, and he had an iPhone SE with a working USB-C port. It works for both charging and USB data, too.

If you’re rocking an iPhone SE, you might dig this conversion as it gives you access to more chargers out in the wild. Plus, you’ve still got the regular headphone jack. Be sure to check out the iPhone 13 with a USB C port, too. It’s the hottest new hack until the new EU regulations hit Apple in coming years.

Berlin Clock Takes Inspiration From Sci-Fi Sources, Looks Incredible

July 7, 2022 by 6 Comments

What would a HAL9000 look like if it eye were yellow and sat atop a front panel inspired by an Altair 8800? You’d have today’s feature, [Stephan]’s BerlinUhr, a gorgeous little take on a Berlin Clock.

At Hackaday, we have a soft spot for clock builds. They’ve graced our pages from early times. When we saw this ultra cool Berlin Clock, we couldn’t resist the urge to share it with all of our readers.  For those of you not familiar with a Berlin Clock, it’s a clock that consists of 24 lights, and was the first of its kind back in 1975.

[Stephan]’s build is notable because not only is it a beautiful design, but the work that went into the design and build. At several inches tall, the BerlinUhr is supported solely by a USB-C connection, although it can also be hung on a wall. The RTC is backed up by a CR1216, and an ATtiny167 provides the brains for the operation.

A neat part of the build comes with the KPS-3227 light sensor, used to adjust the LED brightness according to ambient lighting. Rather than being a straightforward part to insert into the PCB, KiCad’s footprint had some pins reversed, causing [Stephan] to learn how to correct it and contribute the fix to KiCad. Well done!

We weren’t kidding about clocks, by the way- check out the link to the Atomic Wrist Watch on this post from 2005, and this Russian VFD based clock from 2006- with video!

Adding USB-C To An IPhone 13 Is Delicate Work

June 24, 2022 by 4 Comments

USB-C seeks to rule the roost when it comes to connectors, and even has Big Europe on its side. Apple hasn’t had to abandon Lightning just yet, but [Restore Technique] has put a USB-C port into an iPhone 13 to give us all an idea what it’s going to be like in the brave new future ahead of us.

The idea came about after disassembling the iPhone 13, and the project was locked in after seeing the first iPhone with a USB-C connector sell for $86,001 on eBay. The plan had to support fast charging, cable reversibility, and data transfer, without cutting out any functionality or compromising water resistance.

The concept is simple enough: take the C94 board from a Lightning to USB-C cable, and put it inside the phone along with a USB-C port. Of course, actually achieving that is the real challenge. Techniques from melting apart Lightning connectors to carefully peeling apart 0.5 mm pitch flex cables to fit 0.6 mm pitch pads.

It’s an impressive hack, and explained so well it’s actually tempting to try it at home for the sheer challenge of the thing. If you do pull off a similar hack yourself, drop us a line! Video after the break.

Mouse Charging Mod Shows Even Simple Hacks Can End Up Complex

June 9, 2022 by 16 Comments

Hardware hacks have something in common with renovations that involve taking down a wall: until one actually gets started and opens things up, there’s no telling what kind of complications might be lurking. [voussoir] has a project that demonstrates this nicely: modifying a rechargeable mouse to use USB-C instead of micro-B turned out to have quite a few little glitches in the process. In fact, changing the actual receptacle was the simplest part!

On one hand, the mouse in question seems like a perfect candidate for easy modification. The enclosure isn’t too hard to open, there is ample space inside, and USB is used only for recharging the battery. So what was the problem? The trouble is something familiar to anyone who has worked on modifying an existing piece of hardware: existing parts are boundaries to hacking work, and some are less easily modified than others.

A wooden picture frame with an e-ink display

Receive Virtual Postcards On This Beautiful E-Ink Photo Frame

May 22, 2022 by 12 Comments

Sending postcards to loved ones used to be standard procedure for travelers back when travel was glamorous and communications were slow. While some travelers still keep this tradition alive, many have replaced stamps and post offices with instant messaging and social media — faster and more convenient, but a lot less special than receiving a postcard with a handwritten message from a faraway land.

[Cameron] designed a postcard picture frame that aims to bring back a bit of that magic. It’s a wooden frame that holds an e-ink display, which shows pictures sent to it by your friends. All they need to do is open the unique link that you sent them beforehand and upload an interesting photo; the picture frame will cycle through the submissions based on an adjustable schedule. A web interface allows you to change settings and delete any inappropriate images.

A black PCB with an ESP32 mounted on itThe wooden frame is beautifully made, but the sleek black PCB inside is an true work of art. It holds a battery and a USB-C charging circuit, as well as an ESP32 that connects to WiFi, stores images and downscales them to the 800×480 monochrome format used by the display. [Cameron] has not accurately measured the current consumption, but estimates that it should work for about one year on a single charge thanks to the extremely low power requirements of e-ink displays.

Having your friends decide on the images shown in your house is an interesting idea, if you can trust them to keep it decent. If you like to have more control over your e-ink display, have a look at this solar-powered model or this wall-mounted newspaper display.

Bee Motion Combines ESP32 With PIR Sensor And USB-C

May 7, 2022 by 3 Comments

There’s no shortage of ESP32 development boards out there, with many of them offering some “killer app” feature which may or may not align with whatever it is you’re trying to do. But if you’ve got a project that could benefit from the pairing of a powerful WiFi-enabled microcontroller and a passive infrared (PIR) motion sensor, the Bee Motion created by [Paul Price] is certainly worth a close look.

This breadboard compatible package combines an ESP32-S2 module with a top-mounted PIR sensor, making it a turn key solution for all sorts of motion sensing projects. In addition to the expected onboard voltage regulation, there’s also a LiPo charge controller and status LEDs for mobile or battery-backed operation.

While there’s far too many variables involved for [Paul] to give a specific runtime for the Bee Motion, he’s run some numbers and found that a 1500 mAH cell could potentially keep the board running for over a year if you’re taking advantage of the MCU’s deep sleep capabilities. When it’s time to recharge, whenever that may be, the board’s USB-C connector means you won’t be searching around for the proper cable.

Schematics and CAD files are available in the Bee Motion GitHub repo, and [Paul] is also selling assembled boards on Tindie. All you need now is to get inspired by some of the slick PIR projects we’ve covered in the past.

Laptop USB-C Charging Hack Lets You Leave The Brick At Home

April 17, 2022 by 47 Comments

At their best, laptops are a compromise design. Manufacturers go to great lengths to make the slimmest, lightest, whatever-est laptops possible, and the engineering that goes into doing so is truly amazing. But then they throw in the charger, which ends up being a huge brick with wire attached to it, and call it a day.

Does it have to be that way? Probably, but that doesn’t mean we can’t try to slim down the overall footprint of laptops at least a little. That’s what [Joe Gaz] did when he hacked his laptop to allow for USB-C charging. Tired of the charger anchoring down his HP X360, [Joe] realized that he could harvest the PCB from a USB-C charger adapter dongle and embed it inside his laptop. We’ve seen similar modifications made to Thinkpads in the past, and it’s good to see the process isn’t that far removed with other brands.

After popping open the laptop, which is always an adventure in reverse mechanical engineering, he found that removing the OEM charger jack left just enough room for the USB-C charger. Mounting the board required a 3D printed bracket, while enlarging the original hole in the side of the laptop case took some cringe-inducing work with a file. It looked like it was going to be pretty sloppy at first, but he ended up doing a pretty neat job in the end. The whole modification process is in the video below.

The end result is pretty slick — [Joe] can now carry a much more compact USB wall-wart-style charger, or eschew the charger altogether and rely on public USB charging stations. Either way, it sure beats lugging a brick around. If you’re interested in laptop hacking, or even if you just want to harvest the goodies from a defunct machine, check out this guide to laptop anatomy by our own [Arsenijs Picugins].
