At least once a year I try and purge things from my workshop that either I do not need anymore or I have no use for as my storage is always perpetually over capacity. I've left several boxes of items on the hackroom table which includes a variety of items. Parts camera lenses, old computers, cables, cameras, lights, various electronic hardware and network/radio equipment. I have boxes more of much, much more older computer hardware but I have not seen people at the space interested like 486 machines and XT motherboards, alarm clocks and modems in years. There is also that HP multi-function printer/scanner that's been there for a few weeks already that works, but needs the power supply recapped.
Feel free to pick through and take what you want. Anything left over I'll come back in a few weeks and take it out for recycling.
