Still worried that smartphone signals will fry your brain? What about your manhood? Spartan boxer shorts can prevent it from happening by blocking over 99 percent of wireless signals.

That’s just one of the awesome ideas we have in this week’s Crowdfund Roundup. We’ve also got the world’s smallest flashlight, ink made from air pollution, a cute little personal assistant robot, and more.

Bullet 02

The world’s smallest flashlight is now even smaller. Bullet 02 is inspired by the iconic 40 Luger round and even brighter than its predecessor, producing 20 lumens of light from three LR41 button cell batteries. It’s resistant to fire and water, and you can attach it to almost anything.

Bullet 02 can be yours for just $10 when you make a pledge now through Kickstarter. Shipping is scheduled to begin in November.


We use so many battery-powered gadgets these days that keeping them all full of juice becomes increasingly difficult. But not with LYNQ, the versatile 6-in-1 charging hub that has four USB 3.0 ports, a Qi wireless charging pad (perfect for iPhone 8), and one USB-C port.

It’s not just a charging hub, either. LYNQ is also a Bluetooth speaker, and if you hook it up to your Mac or PC, you’ll be able to sync and transfer data to and from connected devices. It even has three handy holes for pens and styluses.

LINQ is available right now for $69 at early bird pricing through Kickstarter, and it’s scheduled to begin shipping in November.


AIR-INK is the world’s first ink made from air pollution. It’s available as a high-quality, water-resistant marker in 2mm, 15mm, 30mm, and 50mm sizes, and as a bottle of 150mm screen printing ink. Using just 30ml of it negates 45 minutes’ worth of air pollution.

Pledging $35 gets you a 2mm AIR-INK marker, while $70 gets you the 2mm and 50mm duo. $150 gets you the complete marker set. Shipping is scheduled to begin in June.


This cute little guy is a personal assistant robot. PLEN Cube can notify you of your alerts and reminders, tell you the weather forecast, and keep you up to date with your calendar. Its built-in camera takes panorama pictures and is capable of face and motion detection, while its speaker can be used to play your music.

PLEN Cube also connects to other smart devices, so you can use it to control your TV, lights, speakers, thermostat and more. You can bag yours with a pledge of $299 or more through Kickstarter. Shipping begins in October.


We don’t need smart underwear, but we do need protection from our smart devices. Spartan is a stylish and “high-tech” pair of boxers that protects your manhood from cellphone and Wi-Fi radiation. They block over 99% of wireless signals, and they’re good for at least 300 machine washes so you can keep them smelling fresh.

Spartan is available in men’s and kid’s sizes, and you can bag yours with a pledge of $40 or more. Shipping starts in June.
