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

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

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).

The L-Cheapo laser cutter is a great tool for artistic projects. Davide Antonello, a graphic designer and artist from Italy, sent us these photos of a monitor he rebuilt using laser cut plywood.


Bringing Faceshields to Verbania

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

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.


Positive Pressure Suit for COVID19

With the shortage of medical PPE throughout the world due to the 2019 Novel Coronavirus (COVID19) pandemic, we have improvised an effective positive-pressure PPE suit. Our prorotypes have already been sent out to American hospitals. Here are the plans!


Donating Face Shields in Marin

With the COVID19 pandemic causing shortages of PPE nationwide, Robots Everywhere has stepped in to help provide resources to our local hospitals. Our 3D Printers have been running day and night to produce frames for these face shields, intended to use semi-rigid plastic such as transparency covers from Staples or Office Depot. See below for the plans.
