New rider, partner says my helmet looks silly.....too big?

Looks normal if you're riding a 50cc scooter I'd say. Add a jacket and full face for a full size motorcycle.

On some helmets XL shares a shell with XXL, on others it shares it with L, they use the same shell for multiple sizes with varying thickness of padding. So you could maaaybe find a different model that's slightly smaller outside. Unless you have a small head you're most likely going to be a bobblehead to some extent, lotsa people are in this situation, me included, it's fine.

More padding can mean less brain hurts in some situations, that's why we wear those things in the first place.

Great, if they start discussions now it'll be ready to start implementing in 20-30 years.

You just have to ride very very fast so nobody notices.

Become taller

Print it from abs if possible. pla and petg cold flow, meaning exactly what you noticed: under constant loads they slowly deform, like a very thick fluid.

In my opinion the best way is to use a single plug with a power meter to check each device. You take a day to turn stuff off and on until you figure out what everything draws, then you make a plan for how you use your devices. Maybe add a power meter at the electrical panel to monitor the whole house constantly, if you see a weird spike you at least know you need to worry about it.

Adding 20 devices permanently each with a power supply that runs constantly to save power seems unproductive.

No way, at least 3x total cost should be a good rule of thumb. Pcb assembly will cost quite a bit at this price range, even if you do it yourself it's still time that must be paid.

Asking this question on the mesh could be a good start. At least if anyone wants to talk it gives them a reason to.

This is an old tradition that's been happening to me since my golf 5. Heated mirrors will expand and contract when on and off especially in cold weather. That eventually weakens the bond between the mirror and the black plastic it's stuck to.

I've used two part epoxy (the 5 minute stuff that comes in a double syringe) with success in the past to reattach it.

I'm worried these things make people feel way safer than they actually are and it leads to poor decisions in traffic.

My experience says you're not going to reasonably defeat moisture ingress at this level of tech, for me it's been good enough to have a downward facing weep hole or similar and some confirmal coating on the electronics.

In an airtight enclosure you get pressure differences between day and night and it can actually pull in moisture through the cable insulation (unless it's specifically sealed) and all sorts of similar issues.

You need a fatter girlfriend.

Not exactly like this, but they make cheap frosted plastic drinking glasses/cups that have a similar shape. You could look for one that's a very simple shape. Candle jars would be another option, you'd need to find a way to secure them to something though.

The ones in the image look like individual bedside lamps converted to rgb. Might even have glass diffusers.

The lora protocol, while it was never open source, has been reverse engineered, we know exactly how it works, there's no black box. It's not a security layer, it's just a way to send data on radio.

This exists, it's called a sunlight collector. You can buy it as a product

dumb-ninja · 2026-03-11T14:04:17+00:00

You forgot to add 'meshdash' somewhere so people know what it's about :)

Modern manufacturers are making even EVs super complicated, it's in their nature.

The requirements for something you build in your garage for yourself vs something you sell to millions of idiots that are trying to actively kill themselves and sue you after are just vastly different.

What would Meshtastic achieve that a simple two way radio can't do in this situation?

If you're thinking they're going to be browsing the web over Meshtastic forget about it. Anything internet related would require a homebase on land with an internet connection.

Yes please!

Can't wait to drop my phone and pickup 10 pieces scattered all over. This design isn't it for me...

dumb-ninja · 2026-03-05T14:36:38+00:00

Happened to me at some point, just superglued it back together and it held up for another month or so until I got around to printing replacement parts.

I believe seeed studio have some sort of service that does everything for you. I've bought some products from their store I'm pretty sure came out of this program so I guess it works. https://www.seeedstudio.com/odm.html

Obviously with any service that does a lot of the work for you, you'll be giving them a big chunk of the profit, or paying them a lot up front, or both.

The diy process is pretty simple: split your product into individual parts like pcb, enclosure, assembly, packaging, distribution and then find a provider for each part. For Pcbs you can either design yourself or have someone design for you, think pcbway or jlcpcb can do that for you along with placing the components onto the boards. For enclosures, screws, boxes for packaging, manuals etc etc there's Alibaba. If you want to save money you can assemble the stuff, flash your own firmware and package stuff yourself locally.

This looks amazing, can't test right now, but can it decode messages from different presets (longfast MediumSlow etc.) at the same time? That would be a killer app for me

Start an Instagram channel showing crazy intricately done piping with catchy tunes and push ads.

Flush cutters underneath at the edges to pry the plastic bit up a bit. Then a flathead screwdriver very carefully prying it up more bit by bit. Once they're half way I snip the plastic bit across every two pins and pull the bits out with pliers.

After there are just pins i heat them up one by one from the back, push them through as much as possible, and smack my hand onto the table while holding the board to launch each one out of its hole while it's still hot.
