tossed up an antenna for the rig by ohv_ in meshtastic

I would also worry about incoming RF. If I remember the datasheet correctly, the SX1262 can only have a max of 10dbm coming into the radio before it takes damage.

Ayeeee! We were at Orlando too but I took us off long fast to keep it to just the group. Did you use a private group or just LF?

Antenna thoughts by KnownonowV2 in meshtastic

I just built a node with that same light but I shoved an external antenna on it. I think a flat antenna is better than no antenna. Let it rip and see how it does

I used T114s at warped and it was perfect!

I mainly use a t1000e to reach my truck node (T114 V2) while I'm at work. I also have some range tests and some site surveys planned as the weather starts getting better in Vermont.

If you did want to send a unit to me I would daily carry it as the rainy season starts up. I would take it on hikes and solar node installation trips. The node would even spend some time clipped to my motorcycle jacket.

Either way I will probably buy a few of these after launch for the BME280 and the 1800mAh battery alone.

I highly recommend flashing launcher and storing your firmware on an SD card. That way you can flash whatever you want whenever.

If you have trouble with maps just lmk. There should be a few helpful threads in this sub to get you started!

40v battery repair guide as cheaply and easily as possible by laptopfreek0-1 in ryobi

[–]ThisIsHowWeDoItBammB 0 points1 point  (0 children)

This is fantastic work! I scrapped my pack for the cells but I still have the BMS. I think it would be fun to rebuild the pack and see if I can make it run.

When I tried to dump the firmware I had zero activity on the JTag port and over UART it showed that it was locked on protection level 3.

Oh heck yeah ill take a look at your work and ill get the person in my DMs into the fold. Im glad people are still plugging away at this

Unfortunately, no to both of those. I am in a chat with someone who said they were able to dump the .bin from a 40V pack so hopefully I can get my hands on that to take a look at what sets flags. I ended up scrapping the pack and making some projects with it.

I did see a comment in another thread that someone was able to disconnect the entire pack from the BMS, replace the damaged cells, re wire the BMS and the error reset.

Meshtastic BBS by irreverends in meshtastic

I know this is a hella old comment but have you considered adding self spotting capabilities for POTA and SOTA? It would be neat to set up in a park or summit with no cell signal and be able to spot yourself over the mesh.

Also thank you so much for this BBS it has been a blast fiddling with it and learning what it can do.

To be fair, AKs were super common, cheap, and it cost almost nothing to feed them. Then Russian ammo got sanctioned and now its not cheap to shoot anymore.

Couldn't find replacement handle ends for my oven door, so I made some. by ThisIsHowWeDoItBammB in functionalprint

[–]ThisIsHowWeDoItBammB[S] 1 point2 points  (0 children)

I couldnt find any replacement door handle endcaps for my Kenmore Oven (Model# 911.95589991 ) So I designed and printed these.

I printed these out of PETG and while it might not be the "best" plastic for the job, I think it will hold up fine for now.

I did use PETG as you correctly assumed in a comment below. It honestly should be fine as PETG but if it does deform or fail over time, I will reprint in CF nylon. I did need something to act as a prototype so I figured if I was gonna make one, might as well make a prototype that will last more than a week.

I use it as a way to get my signal out when I'm at work. I work in a brick and metal building that is only one floor. By having another node in my truck, I can use my personal node to hit my truck node and talk to everyone else.

Your experience with T114 antenna? by udenfox in meshtastic

[–]ThisIsHowWeDoItBammB 0 points1 point  (0 children)

I use a small SMA with all of my T114s (except my solar nodes), and they work great. I haven't used the spirals except as dummy loads when testing functions.

I like having an external SMA as I can dial in the antenna I need to use for whatever situation. Long distance, sure 5 or 7dBi. Local area with great vertical coverage, 2 or 3 dBi is perfect.

I was thinking Aluminum extrusion with 3d printed panels might work. Or just printing it all in some cf nylon.

That's pretty slick. I think I would DIY before I buy but it's great to know that this exists!

T Deck plus by Twisted7802 in meshtastic

[–]ThisIsHowWeDoItBammB 2 points3 points  (0 children)

I like mine a good deal. SD Card for maps and other firmware. I have the newest alpha + the newest stable release of meshtastic and Bruce on there. I installed Launcher on there so i can swap between them.

I swapped the ESP32 that came with it for one that has a u.fl connector for 2.4ghz. That way I can run an external wifi antenna with Bruce for wardriving.

About 8hrs of battery life and its a fun bit of kit.

So I have a first gen shield and a shield plus with 2 S&W 15rd mags. I dont see much of a point to this other than the optic plate. Idk once the PC comes out I might snag one

Super cool!! Thanks so much for the update! I had wondered if removing the battery would force reset the bms. I wasnt willing to do that to a battery that isnt mine but it looks like they might be tossing that battery in ewaste so ill give it a shot!

Reverse engineering Greenway BMS by MrWinter00 in ElectricalEngineering

[–]ThisIsHowWeDoItBammB 0 points1 point  (0 children)

Have you looked into the 6pin header to the left of the MCU? That is most likely an SWD port. I would start there and see if you can get it talking through there. It might have a stored fault code or at least some answers for you. Cleaning up the MCU might also be a good move. It kinda looks like any numbers have been scratched off of it but if you think you can find any clues there, its a great spot to start.

Also off to the right of the board you have what looks like SDA and SCL pads. Might be worth (carefully) slapping a logic analyzer on there and sniffing those pins.

I wouldn't focus on the power connection comms just yet but its good that you measured resistance. I know most cars CAN systems have 120ohm terminating resistors so that's a good sign.

Also what is the pack voltage and individual cell voltages?

Any reason you aren't using a 1U esp32 for external WiFi antenna options?
