Star Trek is often credited with helping spur the development of technologies we have today — the go-to example being cell phones. When a Star Trek April Fool’s product inspires a maker to build the real thing? Well, that seems par for the course. [MS3FGX] decided to make it so. The 3D printed Star Trek-themed phone dock acts as a Bluetooth speaker and white noise generator. The result is shown off in the video below and equals the special effects you expect to find on the silver screen.
Taking a few liberties from the product it’s based on — which was much larger and had embedded screens — makes [MS4FGX]’s version a little more practical. Two industrial toggle switches control a tech cube nightlight and the internal Bluetooth speaker. An NFC tag behind the phone dock launches the pre-installed LCARS UI app and turns on the phone’s Bluetooth. Despite being a challenge for [MS3FGX] to design, the end product seems to work exactly as intended.

We have to admit that we were mislead by the title “Sudden Death: Wall Sign + Night Light”. This naturally conjured up images of deadly night lights, but the truth turned out to be a lot less fatal: [Smerfj] had two weeks to make a present for a friend’s wedding. The project was either a go or a no-go depending on the deadline — that sort of sudden death. But as we all know, deadlines have a way of bringing the motivation out of us that’s not always bad.
The night light in question is a bunch of hand-made circuits, each stuffed into a wooden slice with a letter burned on the face, spelling out [Smerfj]’s friend’s name. But to really appreciate it, you have to dig through the build details.
We didn’t know how to burn precise lettering into wood. [Smerfj] covered the wood in metal foil tape, then cut the letters out of the foil. Now applying the torch blackens only the part of the logs that have tape removed. Slick.
To get accurate lettering cut into the aluminum tape, [Smerfj] made an impromptu projector out of a cell phone taped to a chandelier (approximately a point light source) and a stencil suspended somewhere between the chandelier and the wood target. Naturally, this is best done in a darkened room under tight deadline pressure.
The battery holders are fantastic. Springs from commercial battery holders were soldered to enamel wire and placed in holes drilled just the width of AA batteries. With the length of the battery taken into account, channels were drilled into the wood and copper wires jammed through, holding the batteries in place, and providing the other electrical contact. Brilliant.
And finally, the free-form night light circuits are great. Fine-tuned to draw the minimum current, they’re adjusted to the specific LEDs and phototransistors that [Smerfj] had on hand. Bespoke free-form electronics in hand-blackened wood. That’s a nice gift.
Now [Smerfj] just needs nice packaging to present them in. We’re thinking DIY laser-cut boxes with interior lighting, naturally.
[Vince] and his wife are big fans of [They Might be Giants], so when they were perusing their local Target one evening and stumbled upon a blue canary nightlight, they bought it immediately. While the nightlight was easy for his toddler to use, the LEDs inside started to dim after about a month, and eventually they started flickering like mad as you can see in the video below. A battery swap didn’t remedy the problem, and instead of returning it, [Vince] decided to try fixing it himself.
After poring over the device’s simple circuit, he couldn’t figure out any reason why the nightlight would start behaving like it did. He did notice that a resistor was left out of the device, likely as a cost-cutting measure, so he added one in before replacing both of the nightlight’s LEDs.
With his simple tweak, the nightlight was better than new, saving him from what would likely be a string of annoying merchandise exchanges.

[the4est] put together this quick how to for making a laser based light bulb night light. First, you need to break out the black glass base of the bulb and remove the filament. Scrub the inside of the bulb and pour in the paraffin. Once it sets, you can break the glass, leaving a solid wax bulb. Hollow out the inside, insert a laser pointer, and you’ll have fine glowing night light.
