This neat trick is implemented on the Raspberry Pi-based Twilio Developer Kit for Broadband IoT, with which I’ve been working a lot of late (as a Twilio staffer). It lets you connect a headless Pi to your main machine via Ethernet just be plugging in a cable. It also maintains the Pi’s own wireless connection to the Internet.

Want to bake an Apple Pi? Here’s how you can, for a fiver
Bear with me on this one. What really makes the Raspberry Pi what it is? Linux? No, because there are plenty of machines the open source OS will run on. Linux is a Unix derivative; the basis of macOS is FreeBSD, also a Unix derivative.
Sure the Pi is only 40 quid and small, but for me what really makes the Pi stand out from all those laptop and desktop computers is the fact that it makes its microcontroller’s GPIO pins readily accessible through a handy set of header pins. Unlike all ‘serious’ micros, it’s perfect for connecting to and controlling a whole stack of add-ons, including sensors, displays inputs and actuators.
How to fix iCloud bookmark sync glitches
Has iCloud and/or Safari just borked your bookmarks? This happened to me yesterday; here’s how I fixed it…
Make a Mac ‘Task Done’ NeoPixel notification light
Update There’s now a new post containing revised, working instructions for this project.
Note This article was written some time ago, and the libraries used do not work with recent versions of macOS.
I regularly back-up my Raspberry Pi storage card because it’s so easy to damage the card with an improper shutdown or some such. I back up to a Mac, and you can read how I do it here. This wasn’t much of a chore in the early days when I was working with 4GB cards, but now I use 16GB Micro SDs and I know of folks who have much, much larger storage capacities thanks to never-cheaper cards. All this means the back-up takes a long time. So I wondered if I could create a gadget to tell me the task was done, allowing me to get on with other jobs in the meantime.

US department store Macy’s recently said it is implementing iPhone-based tracking tech the better to encourage browsing punters to buy. Of course, Macy has chosen to pitch this as an Apple technology – figuring, presumably, iPhone owners are more receptive to inducements delivered through technology and have more cash to splash than Android fans.
Connect a Raspberry Pi to a Mac using a USB-Serial adapter
I’m enjoying tinkering with the Raspberry Pi. Alas most of the tutorials and guides available online, of which there are many, focus on hooking the tiny board computer to Windows or Linux machines. Mac-centric guidance is sparse, and I could have used some this week.
