Less Than Production, More than One-Offs

We build things we think are cool. Sometimes, other people agree with us and they want a copy of what we’ve built. If you’re lucky enough to have an enviable product but you’re not ready for full-scale manufacturing, you may be looking at a low-volume production run. [Eric Strebel] walks us through one such instance where he makes some custom color swatches for a show. Video after the break.

[Eric Strebel] is an industrial designer so he plays to his strengths by designing the swatch shape, jig, tool, and hangers. He hires out the painting, laser cutting, and CNC machining. This may seem like a simple statement but some of us have a hard time paying other people for things we’re capable of learning. In some cases, we just have to pay the professionals to do it correctly and keep our focus.

The mentality of small runs in this video is perfect for people who sell on Tindie or want to make more than a handful of consistently nice parts. Our own [Lewin Day] recently talked about his experience with a run of 200 mixers called gMix.

Red Bull Creation Winners: Maker Twins

This year’s Red Bull Creation theme “Reinvent the Wheel” was pretty¬†broad, but the Maker Twins managed to incorporate it quite closely with their winning project which was completed in under 72 hours. They took the idea of urban farming and figured out one way to make farmer’s markets more feasible by helping to eliminate waste and spruce up the presentation of the produce.

The project amounts to a Ferris wheel. Instead of passenger compartments there are modular crates which are built with one wooden pallet each. The wheel itself is chain-driven and allows the system to track where each crate is in the rotation. This data is leveraged for a couple of different uses. One lets the customer select their produce on a tablet app and the crate will rotate into position so they may pick the individual items they want. The machine will also take care of automated watering to ensure the produce on display doesn’t get dried out. The icing on the cake is a separate station for washing and cutting the purchased veggies.

Thank you to Maker Twins for contributing some demonstration “b-roll” for use in this video.

5 Tones, 1 Arduino

Because the Arduino is in such high demand for producing multiple musical tones at the same time; [Jeremy Blum] has successfully figured out the math and other necessaries that will take your once previously single tone producing MCU and turn it into a 5 tone producing machine. unsurprisingly its really just some creative use of PWM control but it all works out in the end anyway and helps prevent you from purchasing additional sound generating chips. This truly does open up some new doors, as [Jeremy] shows with his still in production thingamakit like project: ReacXion.
