CellSol has just pushed a cool new feature to its development branch on GitHub: the ability to bridge networks over the wider Internet, using Internet Relay Chat (IRC).

CellSol kits are now available on the Robots Everywhere Product Store! For those who are looking to expand their CellSol networks, kits to build Arduino Repeater Pylons with and without Bluetooth are available. We also offer a pre-flashed version of the LoRa32 used to set up an ESP32 WiFi Pylon.
We've been quiet lately, but as always, busy. Robots Everywhere is proud to announce its partnership with CellSol, a not-for-profit open-source project dedicated to building a diaster-resilient wireless network free for all of humanity to use.
While we're not quite ready to reveal the projects we've been spending a lot of the fall of 2020 on, Riley has been doing something with an in-development robot architecture in his spare time. This is a Land Raider model from Warhammer 40000, by Games Workshop, fitted up with lights, sounds, a camera, and working FPV drive! While it's not finished yet, it runs and drives, so here's a video and an in-depth look on how he built it.
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!
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.
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.
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.
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.
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).
