More Saltwater Etching with L-Cheapo!

A Steel Plate Etched by Saltwater
Oct 12, 2020

As we said in our previous post, we've got more information on saltwater etching from Bruce Bradley, who's put together a nice instructional video, which we've uploaded to our Youtube channel. Bruce has been using automotive primer as a masking paint for his etching; over here in our lab, we've been using Duplicolor as our go-to brand, but most others designed for sandability and weather resistance are fine. Enjoy the video, and let us know if you have done anything cool with our products yourself!

Sep 15, 2020

The L-Cheapo Mk7 is back in stock! We've also made some small changes to the way we build the L-Cheapo Mk7, and would like to share them with you. It's still the same laser; but the next run should get a wee bit better.

Saltwater Etching Metal with L-Cheapo

A Steel Plate Etched by Saltwater
Aug 26, 2020

We have for you today another submission from Bruce Bradley, the gentleman responsible for the six-year L-Cheapo, demonstrating saltwater etching with his laser. Saltwater etching of conductive metals is a relatively simple electrochemical process. A good Instructable explains the details of the process. The purpose of the laser in etching is to cut the mask material or paint, instead of using a scalpel as in the above demonstration. This allows for complex shapes to be very precisely cut, and with the right mask material, a clean edge mated to the metal.

Another Solar EBike!

The New Bike - Custom Saddle and All!
Jun 18, 2020

This is another ebike, this time built from an ordinary bicycle using a rim mounted friction drive. Designed for a now-defunct client, these surplus parts ended up in our storage closet waiting to be put to use. Waste not, want not.

PAPR Suit from Inflatable Costume

An inflatable astronaut costume converted into a PAPR suit for respiratory protection

Similar to the positive pressure suit we made before, using painter’s suits, we made another one using an inflatable costume. This will work with any similar inflatable suit, like the silly dinosaur, but being space cases we went for the astronaut.

L-Cheapo - Built to Last Since 2014

An L-Cheapo Laser Cutter Module, Original 2014 Model
May 6, 2020

We had an interesting support ticket come in recently; an original L-Cheapo Mk1 needed a PWM adapter to be moved to a new machine. After running for six years, we thought this venerable laser deserved a salute. We don't play around when we guarantee our product for life. (We sent out a custom-designed PWM adapter, of course).

Bringing Faceshields to Verbania

A Robots Everywhere designed face shield being worn in Verbania, Italy
Apr 8, 2020

Our faceshield design is really making a difference. With shortages reaching extreme levels in northern Italy, especially smaller places like K's hometown of Verbania, we had to help. We reached out to every small fabrication shop we could. Eventually, we found one that would help. For the first week of April 2020, we were reaching out to shipping companies and fabrication shops in order to find anyone who would get our faceshields to Verbania.

3D Printing Faceshields

Matteo Borri, Founder of Robots Everywhere in a Bread Bag Face Shield
Apr 2, 2020

Both face shields, and the PET plastic sheets which they are made from are in short supply right now. This project will let you build a face shield from any thin translucent plastic, even a bread bag, by spreading the plastic tightly with a 3D printed part.
