UCL – Embedded – NerfGunTurret

Step 1: Project Presentation This project/instructables shows how to make a nerf gun operated by a remote control. The nerf gun is placed on a bracket which parts are 3D printed and laser cut. That way the nerf gun is able to stand by it self.The nerf gun rotates and moves on the x- and y-axis which results in it being able to move up, down, left and right. However there is also a kind of a dimensional z-ax ...

3D PRINTING A MACRO PAD, SWITCHES AND ALL

Building a macro pad inside of a 3D printed enclosure is hardly news these days. Neither is adding 3D printed keycaps to the mix. But if you go as far as [James Stanley] has, and actually print the switches themselves, we’ve got to admit that’s another story entirely. Now you might be wondering how [James] managed to print a mechanical keyboard switch that’s the size of your garden variety Cherry. Well, the ...

SMARTGLOVE HELPS CYCLISTS BE SEEN

Cyclists share the road with other vehicles, often leading to problems when drivers fail to see or respect the rider’s space. To try and alleviate these issues, [Matlek] built the Smartglove to help cyclists communicate their intentions to other road users. The project consists of a glove fitted with an Arduino Nano 33 BLE sense, featuring Bluetooth and motion sensing on board. Combined with TinyML machine ...

MESSAGE IN A BOTTLE: BICYCLE TRAILER ON A MISSION

Graffiti is a controversial subject, and whether you see it as art or vandalism usually depends where and how you come across it. From the scribbled tag on a house wall, to highly sophisticated murals, they tend to have one thing in common though: making a statement — whether that’s political, showing appreciation, or a simple “I was here”. [Sagarrabanana] had his own statement to make, but chose a less per ...

Tiny Solar Energy Module (TSEM)

Description This is a 1x1 inch PCB module with two tiny solar cells, a highly efficient Li-Ion battery charger and with two regulated outputs (3.3V and 1.8V). It harvests enough power from indoor light to power a simple BLE or LoRa sensor. The board has castellated vias so it can be surface mount soldered onto a mother PCB as well as soldered onto 0.1" headers to be used in a bread board. Based on TSEM I de ...
