[Chris Young] has a physical disability that means he can’t use a mouse very well. He typically uses Dragon Naturally Speaking for moving his mouse using voice commands but has found that it lacks some features he needs and can crash at times.
His solution to this problem was to create a device that will translate IR signals from a simple remote into mouse actions and movements. He is using an Arduino micro for this task, and as you can see in the video it seems to have worked out well for him. He has code and schematics available on his site if you would like to recreate this yourself.
[Chris] has actually built several accessibility devices for himself and others. You should check out his blog for more, including his thoughts on the cost of commercial accessibility equipment vs DIY.

If you haven’t been over to LIFE.hackaday lately, maybe you should check it out.
You could be learning how to be a hero with a wine cork, or how to easily break string without scissors(or your teeth). Need new ways to mount your tablet? We’ve got you covered. However, the story that is probably most important right now is how to keep your ice cream from getting that freezer burnt section on the top.
This week I released a project for LIFE. involving a timelapse rig.
After seeing this super simple timelapse egg timer we had earlier this week, I wanted to have a try at doing a “no tools required” rig for moving timelapse. I used an egg timer to pull it along a table. It wasn’t perfect but it worked. Admittedly not as well as if I had just pulled out a teensy and a geared motor, but still ok.
Over the past few years, we’ve seen [Michael]’s adventures in electronics and lucid dreaming. With commercial EEG hardware, [Michael] is able to communicate from inside his dreams with Morse code and record his rhythmic blinking for data analysis when he wakes up. His project is called Lucid Scribe, and now it’s open to just about everyone – including brain experimenters with OpenEEG hardware.
OpenEEG is a project that aims to reduce the cost of EEG hardware by providing the hardware, electrodes, software, and documentation to build your own EEG headset. It’s a great tool in the field of biofeedback, but [Michael] is going one step further; he’s busy writing an algorithm that will detect REM sleep and play an audio track while he’s in a dream state to trigger a lucid dream.
[Michael] points out that anyone with OpenEEG hardware including the DIY Olmex board can contribute to his Lucid Scribe database. You might also get some lucid dreaming time in, but then you’ll have to wake to the crushing reality of real life.
[Johna and Justin] are working to take the emotion out of playing the market. They built this piggy bank which automatically purchases stock when your coinage totals the cost of a single share. That’s right, just turn the selector to one of your three chosen stocks (Google, Facebook, and Apple are used in this example) and plug in some coins. The bank counts your money, compares it to the current online stock price, and pulls the trigger if you have enough dough. You can check out a demo clip after the jump.
The hardware is rather simple thanks to Adafruit’s programmable multi-coin acceptor. It handles the cash and it’s pretty easy to interface with the Arduino which handles the rest of the work. It connects to a computer via USB, depending on a PHP script to poll the current price. We dug through the code repository just a bit but didn’t find the snippet that does the actual stock purchase. Whether or not they actually implemented that, it’s certainly an interesting concept.

[Ruben van der Vleuten] wanted to get a look at the adventure a package experiences when shipped from one place to another. So he threw together this mishmash of components to record the experience. We certainly enjoyed watching the fast motion video found after the break. We wonder what the shipping agency thinks about this sort of thing?
Camera, digital storage, and battery technology have gotten to the point that it’s both cheap and easy to do this sort of surveillance. But there are a few logistical things that [Ruben] took into account to make this work quite well. First off, he need to hide the camera in a way that would ensure the package didn’t look suspicious. He ended up writing his name on the side of the box and boring a hole through one of the black letters which is smaller than a pea and very hard to spot. To make sure he wasn’t recording a ton of empty (dark) frames he also included electronics to sense motion. When the package is moving the video is always rolling. when not moving the hardware wakes for just 3 seconds every minute to shoot video.

Have an awesome invention that you want to create and sell to the world? Think you have everything all planned out and you’re ready to just let the money flow in? Maybe not. Take a few moments and read [Jonathan]’s first hand experience of a maker start up business that didn’t go anything like he had planned.
[Jonathan] thought he was ready. He had created a unique product and, by taking pre-orders, didn’t have to front any of his own capital. He had shown that there was demand for such a device. The big problem…supply. Selling things was the easy part. Actually making them was another story. Every step of the way had complications. Printing errors, parts suppliers backed out, an international money transfer didn’t go through, postage rates increased, suppliers sent the wrong parts, and he and his wife had a baby. His stress levels were through the roof knowing that his customers had prepaid and were waiting through all the delays.
In the end, [Jonathan] learned a lot and survived the journey. He is currently working on his next invention. If you’d like to learn more about his experiences, you can message him personally. There’s also a Pianocade features video after the break.
