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 […]
Previously I mentioned my Chinese K40 40w laser and how I was planning some upgrades. This is the first follow up – this weekend I fitted a couple of them and did some test cuts! Smoothie board replacement for the main GRBL controller board Activated Carbon filter Lightburn software Can the upgraded machine achieve USA […]
My K40 laser is the most humble of its kind, having analog dial and controls, and basic optics. Even so, the results are fine. Now my mission is to take this little Chinese laser and bring it up to the 21st Century. 1. Optics The default mirrors and lenses are built to a price point, […]
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 […]
While Arduino and Raspberry Pi dominate, there are other boards out there for robot builders. One of the best for rapid robot development is IoTiny from EZ-Robot.
DJI/Ryze Tello Mini-Drone is, as the name suggests, a new and tiny drone from the people who created my lovely DJI Mavic Pro. The important differences are, however, compelling:
I have been writing a lot more about Raspberry Pi than Arduino lately, but don’t get the impression I am leaving the Arduino world behind. Both devices have their benefits, and in fact, I believe they work really well together. Let’s take a look at the easiest way to do that!
You may have seen in the Maker Hacks Facebook Group the latest iteration of my Raspberry Pi based entertainment center. It’s now got to the point where I need a boot menu, so I thought I would share the code and implementation with you! Code See the full code in the Gist. First we need […]
Grove sensors are a plug and play way to add sensors, buttons, displays, and actuators to your electronics projects, without soldering. Let’s take a look how well they work when paired with a Raspberry Pi!
