DIY Double Roller Brayer

We made a double roller hand brayer using two C&P letterpress rollers. The plastic parts to give some tension to the rollers were cut using a laser engraver. Shoddy tig-welding by us 🙂 Hoping that the additional roller would compensate nicely for the small roller diameter… Perhaps a different diameter rollers would even be better? […]

Six Color (monochrome) Letterpress Portrait

We’ve attempted a six color letterpress portrait – a monochrome 6 gray levels (so 7 levels including “non printing white area” for a whopping 1 less than a 3-bit image 🙂 .

While the RileyLink for OmniPod with Loop.app for iOS is a life changing device, carrying it in a waterproof container is a pain in the ass… Here is our disclaimer: MESSING WITH YOUR RILEYLINK MAY KILL YOU, WILL VOID WARRANTIES (is there one?) and MAY RUIN YOUR DAY. We are not associated with the brave […]

Three Color Letterpress Portrait

We just finished a large (31.5″ long paper) slightly-larger-than-life-sized multi-colored letterpress portrait using our Vandercook press. We only used a dozen sheets of paper but luckily we managed to get a few decent yields. We attributed the most fabulous registration of each of the plates to the new servo’s ability to run the press super […]

DIY Laser Fume Extractor: [Stage 4] Electro-Static Filter

Overview: The Electro-Static Air Filter charges the incoming fume into one charge and collects the particles onto the subsequent plate with an opposing charge. It reduces the smoky character of the laser exhaust fume down to visibly clear form prior to the Activate Charcoal Filter. The earlier versions of our laser fume scrubber employed HEPA […]

DIY Laser Fume Extractor: [Stage 2] Exhaust Mixer

Overview: The laser engraver has two 4″ dia. ports for its exhaust output; One from the above and the other from the bottom of the lasing table. We thought about designing and attaching a rigid intake unit directly behind the laser machine to control and direct the flow at the lowest resistance but it didn’t […]

DIY Laser Fume Extractor: Part 1 – The Beginning

Why Another DIY Laser Fume Extractor? For our first “real” laser engraver purchase, we knew we needed a “real” laser fume extractor system. Our goal to cut through and engrave MDFs and Plexiglass required relatively powerful laser machine (130W). That meant burning through glue laden wood materials and solid plastics quickly. Doing this would release […]
