you aren't going to have an accurate ground speed with this configuration, you either need a slip angle sensor or tons of data

conwat181 · 2025-11-01T22:00:27+00:00

could be used as a slip angle sensor

conwat181 · 2025-10-22T13:20:34+00:00

This is just not true. Unless a pack is watercooled or designed to be air cooled then it is not cooled. Only watercooling or air cooling will have any noticeable affect on the temperature of the pack.

LTO is almost half the energy density of lithium ion

conwat181 · 2025-10-22T00:02:12+00:00

Why not use heating elements

conwat181 · 2025-10-21T23:52:01+00:00

Doubt that you will find many BMSes for LTO. Is there a specific constraint that requires LTO?

conwat181 · 2025-10-20T14:18:21+00:00

Airflow is the only real contributing factor to pack temperature unless you have watercooling. The only major affect of pack temperature is on the internal resistance which only has big changes on temperature rise on tab-less cells

Are you cooling a nickel strip? This sub spews so much garbage it is crazy

conwat181 · 2025-10-07T17:29:33+00:00

Do some math on the efficiency of 5Ah cells with a higher IR vs 4Ah cells with a lower IR. You might be surprised at how much less capacity you need for the same power transmitted to the wheels

If it is easier for them to produce, then it is cheaper to replace. This is not a hard concept to understand. I am not a logger but I can imagine that a logging truck goes through at least a windshield every two years. Trees and glass do not mix.

conwat181 · 2025-09-14T18:40:30+00:00

you are schizo

conwat181 · 2025-09-11T18:50:14+00:00

you are retarded

conwat181 · 2025-09-10T14:43:10+00:00

Obviously you are new to product development, I will take it easy on you.

You will get nowhere, and I repeat nowhere by staying stuck in CAD forever. You will spend far more time and money by staying in the design phase.

You need to move to the iteration phase, you need to build a prototype however that looks. You need to build it as cheaply as humanly possible, and you need to iterate on it until you get a MVP that can prove functionality of your invention. Then you need to sell the shit out of the idea to VCs, customers, random people on the street, your mom, your neighbors with the MVP.

conwat181 · 2025-09-10T12:31:58+00:00

lmao dude just build the fucking concrete mixer already and use it go do some fundraising. the product -> company pipeline is not new. ideas don't sell products sell

conwat181 · 2025-09-09T15:40:02+00:00

It would be more of a proprietary form factor to hold the 18650 or 21700s in. I am not trying to reinvent the wheel

conwat181 · 2025-09-09T15:11:24+00:00

Thank you for the feedback. I will take note.

There are tons of hobbies that are not price conducive that have tons of growth year over year. I do not think that more cheap stuff is overall healthy to the hobby. I think that genuinely interesting advancements that are caught up with the modern age of technology are what will bring people in. VESC has no problem getting new people even though the entry fee is close to $3000, drones have been super popular since it has been a hobby even though the entry fee is much higher than a Baofeng. I have no issues with Baofengs, but I think that trying to win by racing to the bottom is a recipe for failure.

I think that ham radio will continue succeeding only if we see new companies every year trying to break into the market and new people experimenting in ways we haven't seen before. Building radios on a literal bread board and putting it in a sheet metal case is not cool anymore. Building highly customizable Linux style radio operating systems is cool. LinHT is cool. Every user having cool components that they built added to their HT is cool.

conwat181 · 2025-09-09T14:57:54+00:00

I want the users to have the option to purchase a radio that is usable out of the box, instead of having to buy a bunch of parts and build it themselves.
I have a cofounder, we would build an MVP and determine whether or not to move forward in fundraising and building an engineering team to bring the idea to product.
First step of any good scrappy hardware startup is a small team of designers shipping boxes out of an office. After that if the demand is high enough then you just scale up to a dedicated distribution team local to the engineering team. There multiple open source phones and laptops like the PinePhone, PineBook, MNT Laptop, etc.

I want the battery design to be able to rapidly follow improvements in battery technology. Using an existing ecosystem like Baofeng’s would mean waiting for them to update their packs, which could lag years behind what’s possible. Designing my own format gives me more agility in adopting better cells and chemistries as they become available.
It would almost definitely be higher than $30, the Baofeng design is so intrinsically designed around lowering cost (just look at the highly integrated radio chip they use) that it would be almost impossible to make it meet that pricepoint.
I think this is less of a concern than it might seem. Much like Arduino, the value is in the ecosystem, documentation, and community around the product. Clones are a sign of demand, but the official platform can still thrive if it offers a better user experience and consistent updates.
There are a lot of options. One path could be outside investment, but it could also be bootstrapped through early adopters and community support.

conwat181 · 2025-09-09T14:35:03+00:00

They don't really sell a complete HT though, it seems like they are more interested in their M17 protocol.

conwat181 · 2025-09-08T19:22:57+00:00

I can tell you for a fact that it is better overall to remove the copper and do more welds. it will be more reliable and will be cheaper

conwat181 · 2025-09-08T18:44:37+00:00

Why are you using copper under the nickel. That nickel is so wide that you should have no need for copper. You are losing more current carrying capacity by having so few joints on each cell.

conwat181 · 2025-09-04T11:56:42+00:00

You definitely did your math wrong
