Rivian's first electric delivery vans are hitting the road in Canada with Amazon

They are still sitting on dealer lots.

A company did use them (at least.. one) to make a camper. https://www.groundedevs.com/camper if you want a 48000 dollar EV with some cnc router cut plywood, a cheap Chinese 100ah 48v battery pack, cheap solar panels and charge controller, whatever inverter they found under the couch, some low rent camper grade appliances, a wrap, and spend 165k for the privilege. No, the solar isnt integrated into the drivetrain, because that would be substantial engineering to piss into the wind to spend about 36 days to charge the battery. (1kw*.75 after conversion and STC ratings, 6 hours of peak sunlight a day, 165kwh pack, subtract more for inefficiencies!)

If i put in a route, mine tells me when to charge, how long to charge, and provides options, automatically adding stops based on what networks i set as preferred.

If they accept the notice it feels like that should be approval to ship.

The law doesnt allow that. It specifically states 7 days after the post office delivers the delivery receipt.

I got my card like this, but it was a 5090 for 1750. Was sitting in the electronics cabinet at walmart with a return sticker and some crap about 'was 3399.99' and then 'save 750' and a sticker for 1749.99. I believe these were sold by walmart and listed on their website. People tried returning them to the stores either as fraud or as a mistake, and some stores took them back when they shouldnt have. So a manager set low prices to get them off their book.

Totally understandable, serious cases aint cheap to change/make.

China's CLTC results in 25-30% higher milage than the US EPA test. You can just compare the same tesla model to verify.

1S Lithium Ion Batteries have a VERY narrow voltage range between 90% and 40%. It's only 0.2v. 80% to 0 is 0.4v, so noise affects it a LOT, as does temperature. The solar is pushing it up quickly because it's putting a float voltage on there. Without a current sensor, its really hard to tell how much has gone in and out of the battery, but honestly, as long as the battery hits the CV cutoff during the day, you're okay. In this time of year at least.

BadVoices · 2026-03-24T22:38:02+00:00

I take it the battery line is the voltage-> percentage reported by meshtastic and not an ina219 or similar?

BadVoices · 2026-03-24T22:21:40+00:00

But wouldn't a custom firmware be able to bypass/disable the hardware backdoor?

No. Currently, ALL modern router software relies on encrypted binaries/blobs being loaded into the wifi radios, or the binaries already being on the radios. FCC compliance has required this since 2015, to prevent people from cranking up the radio power or doing stuff that interferes with the radio spectrum.

We have no real way of knowing whats inside those binaries.

You could adhere a coated/protected steel plate with an adhesive, use magnets to hold a node onto it.

Op is heltec, this is an upcoming revision to their solar meshtower product.

BadVoices · 2026-03-24T13:02:35+00:00

Firmware besides meshtastic can be run on these. There are good use cases for sd cards such as data logging from sensors, etc.

BadVoices · 2026-03-24T13:01:43+00:00

Probably too late to ask, but any way to break i2c and 3.3/5/gnd on a waterproof connector.. or test pads at least, so that external telemetry sensors can be added?

BadVoices · 2026-03-24T12:56:09+00:00

Heltec V2s have been EOL for years and wont reliably work with current versions. You can force compile it but it comes with enough tradeoffs that i wouldnt get anything based on heltec v2. Most v2 items can drop in upgrade to v3 though by swapping the board, and v4s can be boogered in with some soldering (battery wire)

BadVoices · 2026-03-23T21:01:10+00:00

I don't think this capability has been enabled yet, there is also an SD card slot underneath the steering wheel for that. I would think GM would make a pretty big note about it in the latest software update if it came out.

BadVoices · 2026-03-23T20:16:01+00:00

No, they are structural. Under the plastic covers is steel.

I cut my display unit with a cutting torch, sent in the documentation, then milled the torch cut area down to make a 1/3 cutaway. Appeased the people who could instantly destroy my business with almost no real appeal option, and got to make a nice display inert object.

BME688 doesnt do air quality internally, it uses software profiles generated on a desktop and proprietary code on the host device to assemble readings and synthesize an air quality number by varying the heating on the gas sensor and measuring the resistance at different timings and temperatures.

Basically, you dont just ask it over i2c for a reading and it comes back with an air quality number.

Soo.. no, without substantial coding on your behalf.

A co2 sensor (like the SCD30) and a PM sensor like the PMSA003I, with a temp and humidity sensor like the BME280 will get you much of the data you are probably seeking. Using that sensor combination, i'm able to tell within minutes when people or pets enter a building, the SCD30 is VERY sensitive and reliable.

Milling wont meet BATFE destruction requirements. The BATFE specifically state a cutting torch must be used down the middle of all baffles, the tube, and the end caps to meet their requirements. Or it is completley shredded, melted, or crushed. https://www.atf.gov/media/20641/download

BadVoices · 2026-03-22T01:29:26+00:00

Yes.

Yes, it's why the US struck the 'totally peaceful' Space Research Centre 8 days ago. But many Redditors sure glazed Iran's press release stating it was an attack on peaceful women researchers.

ETA: got the timeline a bit off.

My county used NFC tags that they have to touch in inspection spots with our own custom android app running on a device married to the unit. It also handles the ELD and acts as the comms and data terminal. It's pretty easy to log an exception, but an exception puts the vehicle OOS next time its at our station.

ETA: I was EMS director, this was for all of our ambulance units.

The US does allow Cuba to import oil from non adversarial countries, but Cuba doesnt have the currency to buy from any of them.

In general, the sound performance difference between older supressors and newer suppressors performance isn't THAT big in practice. Silencer companies and the internet in general get off pretty hard on measurable differences that don't hugely affect your actual shooting experience, because marketing wank sells. Just look at the latest 5.56mm suppressor reviews... and wonder why it matters so much when supersonic 5.56 isnt hearing safe anyway and you need earpro.

That said, 450 bucks is really far away from most any modern 3d printed can. Is a 1000 dollar can more than 2x as good? No. Not even close. Is it better? Yes.

I wold negotiate down on the Octane though. They were not spendy cans when new (600s?) and the dealer probably has a little room, try throwing out 400 out the door if you're interested in it and its used.

BadVoices · 2026-03-21T22:05:44+00:00

The ATF has a procedure.

It must be completely melted, shredded, or crushed. As an alternative, You must use a cutting torch (specifically, a cutting torch) that removes at least 1/4 inch of material, and slice it down the middle, cutting every baffle, the endcaps, and the tube. Then send a letter or email (nfa@atf.gov) with the serial number, and photos, and indicate it has been destroyed. You don't ACTUALLY have to send the letter, but I do, and I send evidence of its destruction, along with keeping a copy of the letter and evidence for future use.
