Upgrade Your Mac With A Touchscreen, For Only A Dollar

Posted on by

Imagine how hard it could be to add a touch screen to a Mac laptop. You’re thinking expensive and difficult, right? How could [Anish] and his friends possibly manage to upgrade their Mac with a touchscreen for only a dollar? That just doesn’t seem possible.

The trick, of course, is software. By mounting a small mirror over the machine’s webcam, using stiff card, hot glue, and a door hinge. By looking at the screen and deciding whether the image of a finger is touching its on-screen reflection, a remarkably simple touch screen can be created, and the promise of …read more

Crankshaft: Open Source Car Computer

Posted on by

Modern cars and head units are pretty fancy gadget-wise. But what if your car still has an 8-track? No problem. Just pick up a Raspberry Pi 3 and a seven-inch touchscreen, and use Crankshaft to turn it into an Android Auto setup.

The open source project is based on OpenAuto which, in turn, leverages aasdk. The advantage to Crankshaft is it is a plug-and-play distribution. However, if you prefer, you can build it all yourself from GitHub.

The only limitation we can see stems from the lack of audio input on the Raspberry Pi, though we wonder if a USB …read more

Hybrid Interface Brings Touchscreen to Rigol Scope

Posted on by

With pervasive smartphones and tablets, the touch interface is assumed for small LCD screens, and we’ve likely all poked and pinched at some screen, only to find it immune to our gestures. Manufacturers have noticed this and begun adding touch interfaces to instruments like digital oscilloscopes, but touch interfaces tend to be an upgrade feature. But thanks to this hybrid oscilloscope touchscreen interface, even the low-end scopes can get in on the action.

It only makes sense that [Matt Heinz] started with one of the most hackable scopes for this build, which was his Master’s thesis project. Using an Android …read more

ESP8266 Adds Slick Touchscreen Controls to a Stretch Limo

Posted on by

The popularity of the ESP8266 WiFi module has a lot to do with its ability to inexpensively connect to the Internet. However, [hwhardsoft]’s stretch limousine environmental control system explores another use for these modules: a simple way to tie together disparate systems with a common user interface.

On a basic level, the problem is one we’ve all faced: multiple devices with multiple control interfaces create an awkward user experience. Have you ever worked in an office with 6 brands of air conditioner requiring 6 different remotes? Because of its low-cost, support for Wi-Fi, serial, and GPIO, ESP8266 boards are a …read more

Live Stream to YouTube by Pointing a Box and Pressing a Button

Posted on by

YouTube has the ability to do live streaming, but [Tinkernut] felt that the process could be much more straightforward. From this desire to streamline was born the Raspberry Pi based YouTube live streaming camera. It consists of a Raspberry Pi with some supporting hardware and it has one job: to make live streaming as simple as pointing a box and pressing a button. The hardware is mostly off-the-shelf, and once all the configuration is done the unit provides a simple touchscreen based interface to preview, broadcast live, and shut down. The only thing missing is a 3D printed enclosure, which …read more

Touchscreen Oscilloscope

Posted on by

[Marco Reps] didn’t want to lug a full-sized oscilloscope around to measure his ECG while running. He decided to check out the DSO112A which is a tiny touchscreen scope from the usual China sources. The tiny one channel scope can go to 2mV/division at 2MHz and can save and recall up to 24 configurations. It also has access to the data via a serial port so you can use it as a fancy data logger. [Marco’s] video appears below.

Apparently, there is was an older model without the A on the end that was not as sensitive and had some …read more

A Wii U That Is Both Computer And Console.

Posted on by

Legendary sudomod forum user [banjokazooie] has once again demonstrated their prowess in Wii U console modification — this time by transforming it into a powerhouse portable computer!

We loved [banjokazooie]’s RetroPie Wii U mod, and happy to see them back again with this build.  What’s in this thing this time around? Buckle up ’cause it’s a ride: an Intel M5 processor core M on their Compute Stick, 4GBs RAM, a 64GB solid-state drive, a 2K LCD touchscreen, Bluetooth, WiFi, a 128GB SD card slot, two 3.7V 4000 mAh batteries, a Pololu 5V,6A step-down voltage regulator, a Teensy 2.0++ dev board, …read more

Dog-Operated Treat Dispenser

Posted on by

Every good dog is deserving of a treat. [Eliasbakken]’s dog [Moby] is a certified good boy,  so he designed a dispenser with a touchscreen that his dog can boop to treat himself when he isn’t barking up a ruckus.

Adding a touchscreen to a treat dispenser when a button would suffice is a little overkill, but we’re not here to judge. [Eliasbakken] is using a BeagleBone Black — a Linux-based development platform — as this dispenser’s brains, and a Manga touchscreen that is likely to see a lot of use.  A wood-like material called Vachromat was laser cut for the …read more

Huge Functionality, Small Package: A Custom Tablet, Raspberry Style

Posted on by

As the adage goes, “if you want something done right, do it yourself.” Desirous of a tablet but preferring to eschew consumer models, [Stefan Vorkoetter] constructed his own compact and lightweight Raspberry Pi tablet, covering several extra miles in the process.

The tablet makes use of a Raspberry Pi 3 and the official touchscreen, with the final product marginally larger than the screen itself. Designed with a ‘slimmer the better’ profile in mind, [Vorkoetter] had to modify several components to fit this precept; most obvious of these are the removal of the Pi’s GPIO headers, USB, and Ethernet ports, and …read more

A Table From Beyond Infinity

Posted on by

Infinity mirrors are some far-out table mods and make a great centerpiece. Instructables user [bongoboy23] took a couple steps beyond infinity when designing this incredible table tailor-made for our modern age.

Poplar and pine wood make up the framing, and red oak — stained and engraved — make for a chic exterior. Programmed with Arduino and run on a Teensy 3.1, the tabletop has 960 LEDs in forty sections. There are, four USB ports hidden behind sliding panels, as well as a two-port AC outlet and an inductive charging pad and circuit.  A hidden Adafruit TFT touchscreen display allows the …read more
