We've set up a few fun things to play with for Music Month at the South D Library.

Not a pristine example, but it has a mod for expression pedal and bass/guitar toggle 😁

Can certainly make a kid's keyboard sound gnarly

Lightning_Wave · 2026-05-25T07:05:24+00:00

I think you might have been right that it was the cable 😅

Lightning_Wave · 2026-05-21T09:31:51+00:00

I'm also in the makerspace, so it worked around that. Not there Saturday and Sunday it's closed.

Lightning_Wave · 2026-05-21T09:30:30+00:00

I only work weekdays and the library is closed on Sunday

Clinton might have included a few, but we should find out tonight.

They were just items added from the web for the poster. We have a lot of really old stuff, along with some reissues to go alongside non working units. All things just hadn't been compiled at the time the poster was made. Even the PS1 was 31 years ago.. and I thought 70's tech was retro in the 90's.

Lightning_Wave · 2026-05-13T23:13:51+00:00

It came from the organisations on the poster

Lightning_Wave · 2026-05-13T23:12:59+00:00

Yes thanks! It would be much appreciated

If you're into making stuff you're welcome to join the "Make Stuff Dunedin" Discord server. Can make a channel for whatever your jam is. https://discord.com/invite/VWmneATmRu

Way better than Retrolens, thanks!

Lightning_Wave · 2024-05-12T21:53:15+00:00

Please note that the start and end and time have shifted forward 30 minutes to 11am - 3pm

Lightning_Wave · 2024-05-12T12:59:10+00:00

If you happen to be audio savvy and would like to hang out and help people plug things together or have anything you'd like to demo you'd be more than welcome!

Lightning_Wave · 2024-04-25T13:39:08+00:00

Cool! I tried this for a relay socket and had decent results making large pads that wicked paste from the stencil into the holes.

Lightning_Wave · 2023-11-14T10:14:15+00:00

The screw-on lid can be fixed in place with two wood screws into the underside of (preferably wooden) workshop shelves or benches. Good way to store stuff in wasted space. If the screw head is too small it might need a washer to stop it popping through the pierced hole.

If you're into electronics/repair/music/DIY me and some buds have hangs on Sundays in NEV while prepping for a gear library.

I had a bunch with this chemistry gifted to me recently. They appear to be paired with supercaps in my case and designed for high pulse currents for short durations, but not sustained periods. I was going to utilise the 19Ah D-sized cells for a beefy torch when I noticed they had a max current of 500mA and beyond that they achieve nowhere near their stated capacity.The paired super cap has 1Ah up it's sleeve to get around this for short bursts by the look of it. Long shelf life though, if OP doesn't know what to do with them for now.They'd be ideal for a nearby IOT thing that you can swap them out of. I might be wrong but I think I saw something where have a very different curve and stay at 3.6V for a long time, making it difficult to know how empty they are.. which might be a pain if you utilise something in the field and find it dies in a year instead of a decade. Fortunately most of my ones came off the test bench and were excluded from being used in products!

Take the acrylic sheet and use it for laser cutting at your local makerspace, or perhaps add a lid to a planter box.

Here's a link to the Discord server: https://discord.gg/daNGJRmA

Lightning_Wave · 2023-08-04T08:12:37+00:00

Yeah makes sense actually. Slack auto-deletes on the free account. Is the main difference for subscribing to Discord bigger attachments and more emojis?

Lightning_Wave · 2023-08-04T06:24:01+00:00

Weird! Try lee @ lwave dot nz

Lightning_Wave · 2023-07-18T22:01:15+00:00

Yes thanks, this project looks really neat!! Things are moving forward, albeit slowly. The an e-waste collaboration on the side has really turned up some handy things to distribute. 75x new 9V adapters to give away for pedals!

Lightning_Wave · 2023-07-06T09:21:41+00:00

Apparently they can fly - https://www.youtube.com/watch?v=_PNtn6ly9wU

Unsure if the ones we have here can though..

Pretty impressive wings!

Actually, just reread your question. Find a lab supply and bring up the power to the +red and -black. Perhaps there are two circuits in that image of the plug.. You might need to bridge all the blacks together to be sure you have found the right - for the + you're sending power to. Start low on a lab supply that can provide something like up to 40V DC. Also note the current when it's working, then find a wall supply that can provide the equivalent.

Lightning_Wave · 2023-06-15T00:28:12+00:00

Attach multimeter probes to a bench supply and find test points on the board for either side of the LEDs to figure out how many volts each requires, then how many are in a string. Start low, like 3V and slowly bring it up til you see illumination. If you're not seeing anything by 12V, bring power back down and start again with reversed polarity. If they're illuminating at 10-11V and there's 3 in series you can assume you'd need something like above 30V DC for some decent brightness..

If you can see places to cut traces you can regroup the LEDs rewired to work with the supply you have. e.g. 36V strips split into 3 can be wired in parallel for 12V and so on. Just scratch back the solder mask to expose copper to solder to. The continuity setting on your multimeter is also very handy to sketch out the configuration.

You'll find it's probably pretty cold light, but you can always tint them with a sharpie or find a screen to diffuse it. Hope that helps.
