For my 3D printed turntable I obviously need some way to turn the turntable, and preferably for video and scanning, some method to control speed. Fortunately, I have a whole box full of those cheap and ubiquitous stepper motors, the 28YBJ-48 plus the ULN2003 driver board.
Hacks are our tips and how-to tutorials. If you want to know how to do something then this is the category for you!
Have you been wanting a wifi camera? Maybe for some added security, or perhaps to monitor the kids/pets/roommate?
Turn your Raspberry Pi into an internet camera!
The Glowforge Basic does not have the pass-through feature of the Glowforge Pro but with this magnet hack, you can trick the front flap to think the lid is shut fully, allowing you to “pass-in” larger material than usual.
The “Massive Adafruit Arcade Button” is one of my favorites, I just find it comically large. Therefore whenever I get a chance to specify this particular button, I jump at it. As luck would have it, I am building a project for an event the company I now work for is holding. I will write […]
Can you build a DIY version of the Elgato Stream Deck? Many people could tell this is what I was building up to. I think we are getting a lot closer. This, of course, continues my previous Raspberry Pi Zero keyboard emulation article. Where that project used an obnoxiously large red button, however, this project is all […]
I am in the fun position of having a Raspberry Pi project to build for my day job. It brought to light a familiar challenge of how to trouble-shoot and connect to headless Raspberry Pi boards when you don’t necessarily know the host or IP address. Instead of grabbing a HDMI cable (and converter), monitor, […]
One of the many productivity-boosters my nerd friends look to is text expanders and keyboard shortcuts. You know, enter a combination of keypresses, and out pops a signature, particular animated gif, or an often-used regular expression. I was about to launch into setting something like this up, and then Amazon Prime Day reminded me of […]
We are pretty familiar at this point with the 3D design creation workflow. Drawing, dragging and dropping CAD files using a mouse and a package such as Fusion 360, or a browser-based application, such as Onshape. What, though, if you have to create a whole bunch of personalised objects? Opening, editing, exporting doesn’t take long […]
Did you ever want to have your return to your office or home announced with a fanfare? Probably not, but let’s do this anyway 😉 This script will use Bluetooth (built into the Raspberry Pi 3) to detect when your phone is nearby, and if detected will play the MP3 of your choice!
Slack is a hugely popular live group chat system. While a lot of my notifications now go to Discord, as I wrote about here, Slack is still more popular with development teams, and it is what we use in my day job. Being able to notify your team when something happens programmatically can be very […]
