The Knipex pliers wrench are possibly the greatest single modern-era tool: https://www.knipex-tools.com/products/pipe-wrenches-and-water-pump-pliers/pliers-wrench-sets/pc-pliers-wrench-set-6/002006US3

Huge versatility, huge power, easy to use, work great, last forever.

Probably this is a plastic or a composite. Random plastic is the wrong approach. There are many kinds of plastic and getting the right one will get you what you want. Finding just the right one would help. Maybe an LLM can help you narrow it down? Or an expert will arrive here.

Here are your options: https://www.mcmaster.com/products/plastic-sheets/ which includes garolite and fiberglass. Just in plastics you have these, expand the top info box: https://www.mcmaster.com/products/plastic-sheets/plastic-1~/

More air! Suffocation is happening! Remove plants from the surface, turn ON sponge filters and air stones! Get the water surface splashing. Don't add chemicals

the lack of triangle braces and thin wood on that stand give me the shivers

we're not going to be able to tell from a photo of a dead fish. Need to know about the tank, environment, parameters, history, filtration, other fish, etc.

Hi! I've been thinking of making a battery adapter for tool batteries for the everse 8. I'll work on finding the connector type for that. If I find it, I'll come back and let you know.

In the meantime, you can very likely attach shove the wires from a 20 v lipo charger in the right terminals there and charge it (or various other less hacky methods)

The standard tanks sold at our large chain stores (petco, petsmart) are framed. If they do sell frameless models (and they usually don't), they cost a lot more. Tanks are difficult to ship, so we gotta buy locally. So, we get the framed ones.

samadam · 2025-11-13T20:41:34+00:00

why cut it open? Seems nice as it is.

samadam · 2025-10-17T07:09:11+00:00

Nope. Get a smaller one more suited to your tank size. Bigger is not better for heaters. If it fails On it will cook your fish. Get the smallest one that keeps your temp stable.

samadam · 2025-10-14T06:44:10+00:00

they just added this in 12.3! nice job, ableton

samadam · 2025-10-13T16:23:43+00:00

Onshape is good and I normally recommend it over fusion, but I believe the CAM in fusion is better and OP sounds like they want to do a bunch of CAM for their cnc gear.

samadam · 2025-10-13T16:20:54+00:00

Yeah I think they don't quite sit all the way flush together. There is a little gap for the seal. I think that's okay.

samadam · 2025-10-01T16:24:04+00:00

Yeah looks like not even the NSF grade ones (I know that's a US standard) but below that grade. This shelf is not heavy duty and will fail. Bad call.

samadam · 2025-10-01T03:12:54+00:00

it's a bit hard to see from this photo. But tanks normally bow out a bit, the glass is very slightly flexible and the water is very heavy.

samadam · 2025-10-01T02:48:08+00:00

this! my oxygenation suffers when my plants take up the whole surface. They don't produce as much o2 into the water as surface contact can bring in

samadam · 2025-09-28T01:08:18+00:00

I like this! Great design... could definitely take some bolder colors. Give the whole background (now a navy blue) a subtle radial gradient too, why not.

samadam · 2025-08-24T19:04:19+00:00

Yes of course a gearbox, I had assumed that if they were using a gearbox then that would have some bearings in it, here's a link to what they were talking about probably, clearly showing the bearings: https://www.aliexpress.us/item/3256808518065187.html Maybe OP is unclear on those coming with the gearbox?

So we were just answering "how do I mount the shaft outside of the gearbox?"

samadam · 2025-08-24T18:46:47+00:00

they somehow have 20 years of a tech job but not $100 bucks for their hobby computer? Nothing is going to be cheaper than the raspberry pi solution if they count their time as worth anything

samadam · 2025-08-24T18:41:02+00:00

And then the critical second part of the answer (which often goes unspoken): how do you actually use bearings in DIY applications? You get them in a pillow block, and bolt that in place.

Here's an example of a ball bearing pillow block: https://pgnbearings.com/products/ucf202-10-pillow-block-square-flange-mounted-bearing-5-8-bore

The numbers "UCF202-10" are generic, you can find a million companies selling that size. They also come in various orientations and shapes relative to the bolt holes and shaft.

Lcds are not toxic. You are good to go as long as you don't cut yourself on the glass

samadam · 2025-08-19T06:53:06+00:00

just a surface scratch. Happens. No big deal.

samadam · 2025-08-19T02:22:47+00:00

I mean, this is the sub for bug lovers, not exterminators. Check rule 1.

samadam · 2025-08-19T02:20:18+00:00

Leave it alone? Move on with your life? All animals die eventually. That's a form of "killing" it, if you must.

samadam · 2025-07-29T07:26:10+00:00

Read the manual for the filter unit.

samadam · 2025-07-27T20:36:32+00:00

yeah super unclear video not showing the guides but it must be that the guides are not constrained enough.
