Flash a Light Bulb, Win a Prize

How many geeks does it take to flash a lightbulb? Judging from the list of entries in the 2017 Flashing Light Prize, so far only seven. But we suspect Hackaday readers can add to that total.

The goal is almost as simple as possible: build something that can flash an incandescent light bulb for at least five minutes. The system actually has to power the bulb’s filament, so no mechanical shutters are allowed. Other than that, the sky is the limit — any voltage, any wattage, any frequency and duty cycle, and any circuit. Some of the obvious circuits, like …read more http://pje.fyi/PQ6mmt

There will be no special badges for DEFCON. Everyone will still have badges — and our expectations are tempered because of the one year on / one year off schedule for electronic badges — there just won’t be mind-bending puzzles wrapped up in the official badges. What this means: it probably won’t matter if you’re late for linecon, and someone in the DEFCON hive mind still has a Facebook. Also, DEFCON is canceled.

In the past, we have decried the very existence of fidget spinners. It’s what the kids are into, after all. However, an electronic fidget spinner is …read more http://pje.fyi/PQ65f5

Another Helping Hands Build

[Punamenon2] wanted a soldering station with integrated helping hands. He couldn’t find one, but he decided it would be a good 3D printed project. In all fairness, this is really 3D printing integrating several off-the-shelf components including a magnifier, a soldering iron holder, a soldering iron cleaner, a couple of “octopus” tripods, and some alligator clips. Total cost? Less than $30.

In addition to holding the Frankenstein monster together, the 3D printed structure also provides a storage tray with special sloped edges to make removing small screws easier.

We were a bit surprised at the use of the cell phone …read more http://pje.fyi/PQ5KMm

iPad, not Flux Capacitor, Brings DeLorean Back to the Future

Add a flux capacitor and a Mr. Fusion to a DeLorean and it becomes a time machine. But without those, a DeLorean is just a car. A 35-year old car at that, and thus lacking even the most basic modern amenities. No GPS, no Bluetooth — not even remote locks for the gullwing doors!

To fix that, [TheKingofDub] decided to deck his DeLorean out with an iPad dash computer that upgrades the cockpit experience, and we have to say we’re impressed by the results. Luckily, the space occupied by the original stereo and dash vents in the center console is …read more http://pje.fyi/PQ3tP9
