Mercy Me, Thanks For The Heals

Sometimes, you have to call in the experts. [CorSec Props], builders of fine props, costumes and more, were commissioned to replicate Mercy’s healing staff from the game Overwatch. Sounds simple, but the customer — right as they always are — requested that it spin and light up just like the original.

To get a look at the electronics, the rotating head slides off after removing a screw. Inside, the rechargeable 18650 lithium-ion 3.7V battery — via a DC to DC converter — is bumped up to 5.5V in order to run a 12V, 120rpm motor. At full voltage the staff’s …read more http://pje.fyi/PyhcsH

DIY Barometer: It’s For Your Health!

[Taciuc Marius] and his colleague noticed that days with low atmospheric pressure plus caffeine in their system meant a spike in blood pressure. Considering how this might impact his cardiovascular health, he decided to make a relative pressure barometer out of a jar to help him decide whether he should really have another cup of coffee.

Aside from a 3D printer, you’ll need to assemble a small jar with a lid, some screws, lock washers, nuts, and a flexible membrane — a piece of a rubber glove or balloon will do nicely. [Marius] details the build process on …read more http://pje.fyi/PxtfG9

DIY Nintendo Switch May Be Better Than Real Thing

Nintendo’s latest Zelda-playing device, the Switch, is having no problems essentially printing money for the Japanese gaming juggernaut. Its novel design that bridges the gap between portable and home console by essentially being both at the same time has clearly struck a chord with the modern gamer, and even 8 months after its release, stores are still reporting issues getting enough of the machines to meet demand.

But for our money, we’d rather have the Raspberry Pi powered version that [Tim Lindquist] slaved over for his summer project. Every part of the finished device (which he refers to as …read more http://pje.fyi/PwjgBR

Stripping 3D Printed Gears for Science

While 3D printing is now well on its way to becoming “boring” in the same way that a table saw or lathe is, there was a time when the media and even some early adopters would have told you that the average desktop 3D printer was perhaps only a few decades behind the kind of replicator technology we saw on the Enterprise. But as the availability of these machines increased and more people got to see one up close, reality sunk in pretty quickly.

Many have dismissed the technology as little more than a novelty, and even within the 3D …read more http://pje.fyi/Pw85nx

Cheap 3D Printers Make Cheaper(er) Bioprinters

In case you missed it, prices on 3D printers have hit an all time low. The hardware is largely standardized and the software is almost exclusively open source, so it makes sense that eventually somebody was going to start knocking these things out cheap. There are now many 3D printers available for less than $300 USD, and a few are even dipping under the $200 mark. Realistically, this is about as cheap as these machines are ever going to get.

A startup by the name of 3D Cultures has recently started capitalizing on the availability of these inexpensive high-precision three …read more http://pje.fyi/PvlHrR

Opening the Door to Functional Prints

If you are going to do something as a joke, there is nothing to say that you can’t do a nice job of it. If you’re like [Michael], a whimsical statement like “Wouldn’t it be funny to put Gründerzeit-style doors on the server cabinet?” might lead down a slippery slope. True to his word, [Michael] not only installed the promised doors, but he did a darn nice job of it.

Buying new doors was the easy part because the door frame and hinges were not standardized back then, so there was nothing on the server cabinet to his mount doors. …read more http://pje.fyi/PvZ8tK

Mini Spool System for 3D Printing Pen Tidies Things Up

3D printing pens may be toys to some, but they can be genuinely useful tools to repair 3D prints, rescue a support structure, or weld together different pieces. However, [BManx2000] found that the way the filament simply sticks out of the back of a 3D printing pen like a bizarre tailfeather was troublesome.

The solution? A Mini Spool System for 3D Printing Pens, with which you can use your 3D printing pen to weld together the parts after printing them. The unit holds 1.75mm filament coiled under its own tension in a tidy package that doesn’t interfere with feeding. Since …read more http://pje.fyi/PsbZPF
