The Autonomous Sentry Turret is a standalone system capable of detecting and neutralizing unwanted intruders via a barrage of soft foam darts. Built for the office environment, the AST is a powerful piece of hardware that needs no human input (although you can remotely disable it, for y'know, safety reasons). Consisting of a modified electric Nerf gun mounted on servo mechanism, the machine is Intel Edison-powered and fitted with a long-range lidar and motion sensor. Read along to see how it's m
The uRADMonitor model D, or the Portable Environmental Monitor, has entered this year’s Hackaday Prize competition, throwing in a complex hardware design, backed by a matching software infrastructure implemented with thousands of lines of code. What started with a simple hand drawn diagram was followed later by the Beta prototype and finally led to the …
Introduction For many of us, we started out programming on desktops and servers, which seemed to have infinite memory and processing power (well, depending on when you started programming, I guess). There was little reason to optimize your code since...
High speed photography is fun. Ultra high frame rate video, even more so. But since not many of us have access to $10,000 HFR cameras… we have to make do with long exposure shots a perfectly timed camera flash. You can design a system to trigger the flash at just the right millisecond — but they’re still pretty expensive typically.
Hi!In this Instructable I will tell you how to make a good looking smartphone alarm clock. The alarm clock displays the time, can charge the phone and houses a mini amplifier and speaker. I had the idea to build this alarm clock for a long time but the "Time" contest helped me to get started. The design is inspired by the Areaware alarm clock. I loved the design and simplicity from the first moment I saw it. The disadvantage was that the costs where a little bit high for only a piece o
Let’s equip Arduino with a serial-interface JPEG Camera with IR and try two applications: the first one saves shots (on a SD-card) at regular intervals while the second uses a PIR sensor to detect intrusions and photograph what happens. Recently, miniaturized cameras with serial communication interface have been launched on the market. Compared to traditional cameras, they offer easier integration with Arduino or other microcontroller-based boards. It is quite easy to understand that using
In this project, we will learn how to logging data from Raspberry Pi using Python and Excel which collect data and save the output of the collection or analysis.It’s a quite quick project and can be used either on its own or part of something bigger (Check it Out >> Integrated Weather Station).
Hi! Kaeru no Ojisan is back with Car No.06. Car No.06 is a Programmed Automatic Driving Car with following procedure; – Simulate the Car Trajectory based on the Target Passing Points. – Drive automatically as simulated using Reflective Photosensor and Gyro Sensor . – Adjust Car Position to the starting point using Web Camera, after […]
FabScan is an open-source, do-it-yourself 3D laser scanner.It started out as a Bachelor's thesis by Francis Engelmann, supervised by René Bohne. You can find official project here.I made my own box from MDF hood sheets and use different hardware parts.I decided to make this guide to show to you my work.All credits for Arduino software and computer application goes to FabScan team, so thank you very much for this great open source 3D laser scanner!Dev: Francis Engelmann Official page: hci.rwth-aa
Of all the things we do at Raspberry Pi, driving down the cost of computer hardware remains one of the most important. Even in the developed world, a programmable computer is a luxury item for a lot of people, and every extra dollar that we ask someone to spend decreases the chance that they’ll choose …
