The simple version of the eyetracker just uses the endoscopic camera and attaches it to the frame of the safety goggles - no soldering or 3D-printing required. This can be done in small groups of students (2-3) within 45minutes, once the materials are...
Parts Selection I would say in general there are four categories of parts that you need to manage where some are customizable ordering-wise while others are fixed. The PCBsThe Electronics BOMThe Miscellaneous BOMThe Housing The PCBs Honestly the...
I'm a pretty mechanically inclined person, not a "code person". So, briefly, here's an overview on how 3D printers work, assuming you don't know anything about 3D printers, like I didn't. If you do know, you can probably skip this part. Motors and Sensors...
Starting When I set out on this project, I was recovering from a killed project, a single servo-driven binary clock. I had just learned fusion 360 and jumped into a big project that was too much too fast. The Geneva Drive worked fine but there were too...
The following tools and materials were used in this project: Tools and materials: 3D printer (link). It was used for printing the case where the electronics are encloused.Solder iron and wire. Some of the components (ESP8266 Firebeetle and...

We've seen a lot of hand-made masks using beautiful fabrics and also know that they can be helpful but are not medically tested. Beyond common sense, there are quite a lot of studies on the effectiveness of different types of masks. Prof. Supratik Guha...
Since I focused on building a budget-friendly and accessible mechanical anomaly detector that detects sound-based mechanical anomalies and diagnoses the root cause of the detected deviations via object detection so as to notify the user via SMS, I decided...
WARNING! As of autumn 2023 the new hardware version is internally completely different and doesn't have an ESP but something called "W701" that will probably be supported by OpenBeken at some point but currenty (Oct 2023) not. The W701 (apparently RTL8720)...
The workhorse of the QwickFab system is the exposure table used to expose photosensitive copper boards to UV light. Its major parts include: UV Light assembly replacement for Sparkmaker 3D MSLA printer5.5 Inch replacement LCD Screen with glass...
To build the dial, you’ll need to get the kit with all the required custom PCBs from my Tindie Store,you can get the boards alone and source the rest of the parts yourself, I also have the full assembly kit with all the required parts available...
Since our object is to drive an actual stepper motor with an Arduino, we'll need some hardware. Before we jump into the software, we need to connect our motor and driver to the Arduino. I'll also briefly discuss the driver and motor types and their strengths...
1: Designing Your RobotOverviewIn this step you will design your robot and learn a little about computer aided design (CAD) while you're at it. After you finish the design, you will send the robot desing file to our factory via email so that we can start...
This is an introduction that briefly describes the process of bringing laser taggers from the back of my mind to something I can hold in my hand. The long, long LOOOONG version can be found on my blog which details every day of the process which took...
