Jamie O’Shea decided to try to build a telegraph using nothing but stone-age tools. He uses nothing modern, except information. He is wearing a suit, though I suspect that is for dramatic effect — collapse of civilization and all that. Or he may just have a day job.
Some people have viewed this project through the lens of sustainability. While self-sufficiency and locally sourced material would certainly seem to be sustainable, my methods fail quite spectacularly in environmental analysis. For one, I used an estimated 20 kg of charcoal to produce perhaps 20 g of metal. Much of this was wasted in the learning curve, but it was used just the same.
I had zero emissions control. While roasting my copper ores, I directly vented all the gases being produced. The noxious sulphur dioxide, chief precursor to acid rain, gagged me when I got too close. Moreover, I got sick twice after this phase of the process. At first I assumed this was from the sulphur, but after further reading, my symptoms more closely resembled mild arsenic poisoning. Arsenic is a heavy metal usually found in ores of copper that sublimates away during the roasting process. So I have to issue a “don’t try this at home” warning. The only way I can see this process being described as sustainable is that I was distracted from more effective activities of consumption for 6 weeks. But this is easily canceled out by the 3 round-trip cross-continental voyages taken to complete the project.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
