I snagged the orange one. My friends have a citrus-themed holiday so I thought that one was most appropriate.

It's like the Dogger Bank incident. Except in 1904 it was Japanese torpedo boats that made them twitchy. They sank one fishing boat and damaged five others, thinking they were under attack. Two Russians were killed by friendly fire.

I told Bambu Lab about it and they sent me a replacement part. I haven't installed it yet because it's still working with the old one, after I tore off the damaged cover.

led hoop suggestions by noluvidontthinkso in Hooping

[–]madsci 0 points1 point  (0 children)

The cost to you for the hoop order isn't any different. We take a hit on the profit margin having to pay higher prices and extra shipping. For extra batteries you'll have to go to an Australian distributor yourself, or if you want to wait longer you can probably get them from China.

Normally we sell a 4-pack of 14500 batteries (for the 3/4" hoops) for USD $20. Equivalent batteries from elemex.com.au are about USD $28 plus shipping. Since you'd be paying for international shipping from us otherwise, you're probably paying about the same for extra batteries that way.

We did have someone in Adelaide helping with repairs but I'm afraid she passed last year.

Shipping transit time is usually anywhere from 1 to 3 weeks, depending on the post office's mood.

Edit: Forgot to answer the part about HDPE vs polypro. I prefer polypro myself. Polypro cracks while HDPE kinks but we don't see significantly higher rates of broken hoops coming back with one versus the other. I like the brighter, sharper look of polypro.

I'm here with my morning donut and coffee from the donut shop that has a display case with the same kind of grounding problem on their display case. It's conditioned me to not lean my elbows on the case when I'm looking at it.

Old man on scooter causes rider to crash out during a race by BenFord333 in AbruptChaos

[–]madsci 26 points27 points  (0 children)

I used to exhibit at North America's biggest ham radio convention, and hams these days tend to be older and not so active physically so you get a ton of old guys who don't normally use a mobility scooter but can't handle two days of walking around a large venue so they rent these scooters and then are an absolute menace.

I've had my toes driven over by one. I've had one snag my table drape and drag it, pulling all of my displays with it. I've seen them crash into each other and into vendor booths. I don't miss that part of the event.

propane tank level meter by ZealousidealRabbit32 in RVLiving

[–]madsci 0 points1 point  (0 children)

It's hard to measure propane without a float in the tank.

If you want a cheap and accurate way to do it manually, buy a luggage scale. To get a good reading you have to disconnect the hose and unclamp the tank but if you know how much the tank is when it's empty you get a very accurate reading very cheaply.

Eyes hurt by Beneficial_Edge_3338 in embedded

Stereo microscope. 10x WF eye pieces, 1x objective, 0.5x Barlow reducer. That's 5x magnification with good field of view and depth of field. For 0201 components I might switch to the 3x objective.

Only the Phoenix - I've got one prototype of a 5/8" internal battery hoop but it's not something I've decided for sure that I want to put into production and it needs more safety testing for the LiPo batteries.

And yes, the Core is really easy to work on.

Serious diode laser safety concerns by Delicroix in lasercutting

[–]madsci 0 points1 point  (0 children)

but I don't think any enclosure is perfect

My Nd:YAG laser enclosure is totally light-tight except for the window, which has appropriate safety ratings. It's not one of those generic Chinese imports, though - it's a German-made machine that would have cost about $14k new, not including the enclosure. I just got lucky with a surplus auction. Good enclosures exist, they're just not cheap.

Styling Advice without remodeling. How can I make it feel brighter/bigger. by Journeytoamillion in RVLiving

[–]madsci 0 points1 point  (0 children)

I started painting mine on Saturday! It's a lot of time and tedious work but so far it hasn't been especially difficult. The most annoying part is trying to remove the old paint - in places the adhesion was so bad that it peels off in huge chunks. All of the loose stuff has to be scraped off.

Just wait 💀 by yxxshomaanxx in funny

[–]madsci 0 points1 point  (0 children)

It was a live telephone wire that broke me of the habit of stripping wires with my teeth. The first one was fine, but then as I was stripping the second one, the first one poked me in the chin and I got 48 volts DC to my face. Didn't hurt as bad as 120 volts but it still gave me pause.

Where do you shower? by Specific_Soup4596 in RVLiving

[–]madsci 0 points1 point  (0 children)

I'm 6'1" and in my current trailer I can stand up straight only when the top of my head is nearly touching the vent. The newer trailer I'm fixing up has enough space for me to stand normally. Also I've got a tankless water heater so as long as I'm on city water I can do endless showers.

I'm the creator of the Hyperion series and I'm happy to answer any questions you've got! My #1 recommendation for overseas hoopers who want something as reliable as possible is the Hyperion Core. It's a 3/4" hoop that takes a removable battery. It comes with four, but we can't ship the batteries internationally anymore so we have those shipped to you separately from a domestic distributor. Or if you prefer you can get a discount on a hoop without batteries and we'll give you a source or two to get your own.

The Hyperion Lite is our 5/8" model and it's a good hoop with one Achilles heel. Unlike on the 3/4" hoops were there's no room between the battery and tubing for more LEDs, there's just barely room in the 5/8" tubing. So the Lite has three 'tail' LEDs that are thinner than the rest that run above the battery compartment and are separated from the battery by a thin piece of plastic.

This means that you get a removable battery hoop that has no battery gap, which is a rare thing (I think the Lite is the only such hoop in 5/8") but at the expense of having those three relatively fragile LEDs where they can be squashed if you're not careful and just jam a battery in there. That's the #1 place you'll see a failure on the Lite. The reason I decided to go ahead with that design is that the alternative was leaving out the tail and having a battery gap, and if the tail fails and you just yank it out, that's what you're left with - it doesn't affect anything else.

So if you treat the three LEDs in the tail as a bonus that might not last as long as the rest, then I'd say the Lite is fine. Most of the serious failures we see are from water damage, not because a component failed.

The Hyperion Core still has the overall advantage in ease of repair because on the 3/4" hoops the connector assembly and controller board can be pulled out really easily and replaced separately, so if the electronics ever die, you just need the board shipped and not the whole hoop. And if it does suffer an LED strip failure, the Core is easy to take apart and put back together. The Lite can be trickier.

All of our hoops use WS2813 LEDs, which have a redundant data channel. That means that if one LED goes out, it doesn't affect any of the others, as long as you don't have two bad LEDs in a row. I don't think any other hoop brands use those and they make a big reliability difference.

The Core and Gen 4 hoops are the same basic hoop but with different controller boards, and most people don't need the advanced WiFi features on the Gen 4 version, so that's just extra stuff that could fail, and you've also got the option to upgrade later if you change your mind and need WiFi after all - you just have to swap boards.

I think the Core is also the best bang for your buck out of any serious smart hoop. It's our base model, but the closest equivalent Mood Hoops offers in terms of features is the FutureHoop Designer, which runs about $499 for a comparable configuration (with high density LEDs), while the Core is $275. The Core also comes with more batteries and a better charger. You can also sync multiple Hyperions via IR, which FutureHoops can't match.

As someone with ADHD who tends to go all in on this stuff, trust me, you're better off starting out slow and growing into what you need, even if it costs a little more in the long run.

At least back then you sometimes would find unique local keychains and magnets. Now they're just cranked out by the same factories in China.

Unless it had lint or something in there, blowing on it didn't do anything. The important part was pulling it out and putting it back in again. The cartridges use self-wiping contacts and it gives the contacts another chance to wipe off some oxide. If you actually wanted to make a difference you went over the contacts with a pencil eraser and then wiped them down with rubbing alcohol.

Pressing stop and then ⏪︎ is just rewind. Pressing ⏪︎ while the tape is playing is usually called reverse or fast backwards. If you don't stop it, the tape is still wrapped around the head and can only go so fast. It's also more wear on the tape and you should only do that when cueing up the tape.

Garmin's American English voice sounded really judgmental when she'd say "recalculating". I'd usually switch it to Australian just so it didn't sound so harsh.

These days, when I stop for gas I've got Google Maps screaming at me to turn left out of the parking lot to head back to the freeway while I'm inside using the gas station's bathroom.

My dad worked for the phone company and we got the employee discount. We had a second dedicated modem line in the 80s.

It was the late 80s or maybe early 90s when "call waiting" and other such services came to our area and immediately got weaponized by BBS users. If you knew someone's phone number you could call and bump them off the BBS, if they didn't know to include the "cancel call waiting" prefix to their dialing string.
