Rebuilt my snowblower engine in the kitchen with my kids. Something had gone through the cylinder and gouged the wall pretty deep, so bad that it was way down on compression. Anyway, just did the first oil change after and found a gear tooth umder the oil drain, so I was concerned something broke internally, but afyer looking at it closely, it seems to be a ring gear tooth... no idea why it was laying there. Made me nervous for a second haha

Anyone here using #Meshcore or have an opinion on it? In Ottawa, everyone has switched over to it from #Meshtastic I flashed a couple Heltec v3's with Meshcore to try it out and its pretty cool! I was able to connect with people over 40 km away, via hops, and from a frozen beach in the open. Unfortunately the lora range seems worse than Meshtastic, so I cant reach areas I normally could in my area. So far Im thinking it is really cool, and I will run both... would be cool to setup a meshcore - meshtastic bridge for myself and local mesh.

Got my #immich demo disk!

Pretty cool!

Trying to figure out this injector driver module from my truck... It died about a year ago, and I just replaced it at the time, but now I want to repair this one for fun. When it failed, one injector bank quit firing the high voltage. The high side control was open. The only obvious damage was a few burnt resistors and transistors. I replaced all the burned parts and plugged it in, but as soon as it started, everything popped again. Next, I pulled the MOSFETs that control the high side voltage, replaced everything again, and plugged it in… this time nothing burned with the MOSFETs removed. One of the MOSFETs (the bad side) shows about 50 V on the gate when it’s supposed to be low. The good one only has around 1.5 V. When the good side fires, its gate jumps to around 98 V then drops back to ~1.5 V. The bad one just sits at 50 V and drops to ground only when the good one fires. So it seems like something is shorting power to the gate of that MOSFET. I’ll have to replace all the resistors and caps again (I shorted something while testing), but once that’s done I want to track down why the gate’s stuck at 50 V. Maybe another shorted transistor or something... Another weird thing with this, is that the MOSFETs are N channel, so they need higher voltage at the gate than the source to fire, but the voktage seems to be lower… I may just be misunderstanding something there, or they need to be installed for the correct voltages to show up.

Jumpscared by a renault 12 last night.

Trying to figure out where that pad connects to.... Forgot to mention that the pad directly beside it, on the other transistor (pad is fine) is also the same l with no apparent trace to where it goes. Been trying to continuity test it but can't find it's trace anywhere. View quoted note →

Well... Shit. I'm trying to repair this busted injector driver module for a 7.3L PowerStroke but I totally suck at soldering tiny stuff and ripped a solder pad off for one of the little transistors. Of course its the only pad which doesn't have an obvious trace that I can solder a tiny wire to in an attempt at repairing it. I cannot for the life of me figure out what that pad connects to electrically. Also I discovered the real problem after destroying the pad... A burnt resistor that I traced to the gate of the bank one main power MOSFET. That was the issue all along... a simple easy to replace item. Oh well, I will try to figure it all out and slam new parts at it and cross my fingers.
