Collaborate Disseminate
Join us on Wednesday, October 7th at noon Pacific for the DIY Lasers Hack Chat with Les Wright!
It’s not too much of a reach to say that how we first experienced the magic of lasers sort of dates where we fall on the technology spectrum. For the youngest among …read more
When it comes to portable bicycle tire-inflating devices, hand pumps require a lot of effort, while CO2 cartridges are single-use only. That’s where the aluminum Choka bike frame comes in, as it doubles as a compressed air tank.Continue ReadingCategory… Continue reading Pressurized bike frame fills flat tires
Once upon a time, 3D printing was more of a curiosity than a powerful tool, with many printing trinkets and tchotchkes rather than anything of real use. However, over the years as technology and techniques have progressed, we now see more application-ready builds. This water pump from [Let’s Print] is …read more
What’s the coolest thing a person can build with LEGO? Well it’s gotta be an air conditioner, right? Technically, [Manoj Nathwani] built a LEGO-fied swamp cooler, but it’s been too hot in London to argue the difference.
This thoroughly modular design uses an Arduino Uno and a relay module to …read more

Tending to a garden is usually a rewarding endeavor, as long as there is good soil to work with. If there isn’t, it can either get frustrating quickly having to deal with soils like sand or hard clay, or it can get expensive by having to truck in compost each …read more
A while back, [Emiel] aka [The Practical Engineer] created a hands-free Oreo dispenser for his shop. This was a necessary addition to his fleet of handy tools, and allowed him to multitask much more effectively by using a sander, for example, at the same time that he needed to eat …read more
Portable, cordless air-compressors aren’t exactly new, but they’re often bulky, limited in scope and ugly. In response to these issues, a team of engineers and product designers fro Hong Kong has come up with the Norshire Mini. A compact, min… Continue reading Norshire Mini 8-inch portable air-compressor for bike, car and camping
Imagine a tub overflowing with bubble bath, except it’s a club dancefloor and music is pumping all night. This is what is known as a “foam party” — a wild and exciting concept that nonetheless many are yet to experience. The concept exploded in popularity in Ibiza in the 1990s, …read more

Rub two pieces of metal against each other hard enough, and it won’t be long before they heat up sufficiently to cause problems. That’s especially true when one is a workpiece and one is a tool edge, and the problems that arise from failing to manage the heat produced by …read more

With the proliferation of 3D printing in the new millennium, stepper motors are no longer those idle junkbox inhabitants you pulled out of a dot matrix in 1994 and forgot about ever since. NEMA standard parts are readily available and knocking about just about everywhere. Now, you can readily turn a stepper motor into a peristaltic pump with just a few simple 3D printed parts.
The pump consists of a bracket that fits on to a standard NEMA-14 stepper motor frame. A rotor is then fitted to the motor shaft, constructed out of a 3D printed piece fitted with a …read more
