Interesting electronics projects ↗
A dense historical index of radios, oscillators, sensors, imaging, software radio, test gear, computers and robotics.
End Up Here · a capability shelf
Things to make, measure, repair, animate and understand. A retro doorway into electronics, science toys, small computers, robots, instruments and the practical imagination gathered around them.
01 / The proposition
A small workshop is not merely a room full of components. It is a way of staying in contact with the world: detecting what is hidden, repairing what has failed, building a tool for an unserved need, or making a phenomenon visible to somebody else.
The question here is not whether everybody should become an engineer. It is what useful capabilities remain worth having when intelligent tools become abundant and people have more freely chosen time.
Post-agentic, not post-apocalyptic. The workshop can support resilience and local independence without making collapse the centre of the story. It is about agency, curiosity, care, repair and shared attention.
02 / Open a drawer
The archive is large, so the first view should be simple. Each door is a route into a capability, not a dump of links.
03 / Electronics Hobbyist
The AMASCI electronics pages show the hobby as a whole ecology: components, radios, amplifiers, sensors, scopes, software, repair, robotics, suppliers, scratch-built computers and explanations of what electricity is doing.
A dense historical index of radios, oscillators, sensors, imaging, software radio, test gear, computers and robotics.
Educational routes, circuit archives, design software, kits, books, embedded processors and the wider hobby ecosystem.
A small model of motion, magnets and visible electrical effect—an excellent historical source card.
A route from static charge and fields into sensors, measurement and the pleasure of finding what cannot be seen directly.
04 / Things you can build
The public catalogue will not copy old instructions wholesale. It will ask what a project teaches and what capability survives after the original kit, supplier or component disappears.
Thermometers, digital sensors, electrometers and simple scopes turn the environment into something a person can notice and discuss.
Field bottles, holograms, Schlieren images, infrared goggles and microscopes extend ordinary perception.
Transistors, batteries, radios and motors are not just parts; they are ways of recovering agency over everyday systems.
Van de Graaff displays, traffic models and magnetic toys become public experiments when another person can see the idea happen.
05 / Robots and moving things
The AMASCI toy pages preserve a history of robotic vacuums, RC tarantulas, micro helicopters, rovers, Furby hacks, LEGO Mindstorms, robot lawnmowers and camera-vision kits. The point is not nostalgia alone. It is the question of which capabilities survive when a product disappears.
A small domestic machine that made navigation, sensing and household autonomy visible as a toy-sized idea.

Crystal radios, three-penny radios, simple receivers and transmitters form one of the clearest small-workshop traditions: communication built from understandable parts, patience and attention.
Crystal radios, a ten-minute radio, household-item radios, a transmitter and the three-penny radio.
The catalogue question is not “can this replace a phone?” but “what does it mean to understand how a signal gets from here to there?”
07 / Seeing the invisible
Some of the best material in the archive does not produce a useful product. It produces a new way of noticing: infrared, hand-drawn holograms, microscopes, visible sound, magnetic fields, solar furnaces and thermal effects.
This is where the workshop becomes more than electronics. It becomes a way of making the hidden world available to shared attention.
08 / Power, heat and motion
Generators, motors, batteries, solar experiments, heat engines and pumps belong here. They are useful as models even when the historical apparatus is obsolete or the old instructions need modern review.
09 / The historical shelf
Old kits, catalogues, supplier pages and science magazines are not merely obsolete shopping lists. They record what ordinary people were once encouraged to learn, repair and imagine.
They belong alongside the Whole Earth electronics shelf and the Science Hobbyist tribute: not as endorsements, but as evidence of a culture that assumed people might build some of their own understanding.
10 / The specialist cabinet
Safety boundary. Some source pages involve mains electricity, lethal high voltage, stored charge, heat, lasers, radio transmission, microwave-oven internals, chemicals, pressure, projectiles, explosives or possible X-ray production. This page is a reading and catalogue guide, not a construction manual. Historical instructions do not override current law, electrical codes, laboratory practice or qualified supervision.
Those subjects can be described, historically situated and linked to the original source. They should not be presented as casual “try this at home” projects.
11 / The route forward
The full AMASCI register remains the research layer. Public pages will select representative objects, group the rest by capability, cross-reference relevant End Up Here work, and keep uncertain or unsafe material clearly labelled.
Source → capability → activity → possible life.
That is how the archive becomes part of the website without becoming a dump.
