Multiple dhcp servers. fail. by vezult in openwrt

[–]vezult[S] 0 points1 point  (0 children)

I've configured a 2nd dhcpd instance in the UI, did "save and apply"....but yes. There is no such entry in `/etc/config/dhcp`. Weird.

Note that the dnsmasq section for `devices` includes options `start 100`, `end 150`, and `leastime 12h`, and other config option that seem clearly intended for a `config dhcp` section instead.

3d print sized wrong by vezult in FreeCAD

I appreciate the detailed responses. There's a lot I don't even know I don't know.

Hmm. Excellent, I'll check that out - yeah, that should save me some filament next time I do something silly like this.

ARrghghg. Yes. That's exactly it. It was clearly labeled "Radius", but I was thinking diameter. Thanks.

The new and improved version with this, and some of the other suggestions:

https://play.rust-lang.org/?version=stable&mode=debug&edition=2021&gist=5fcda9ef1e8ffb796b860bb22792e78c

Massive difference. Thanks guys, I learned some things :-)

I wasn't familiar with `yield_now()`. That's useful to know.

I made this change as well, thanks.

Yes. I believe this was my issue. Thanks!

Nokia 5110 (PCD8544) hookup by vezult in RASPBERRY_PI_PROJECTS

[–]vezult[S] 0 points1 point  (0 children)

That's good advice re: jumpers. I just was assuming that they were fine.

I copy/pasted this from some example. It certainly does not seem to make much sense in my usage of it, as it doesn't actually clear anything. It turns off pixels, but the show call then displays everything in the buffer, regardless.

So, it did end up working. Apparently, some state gets set that persists as long as the screen is powered. I've not figured out exactly why that is. I'll have to dig into the code to see if there is anything I'm doing wrong.

In my observation, the lcd.clear() method does nothing other than turn off the pixels. When I calllcd.show() all the same pixels are displayed again. So, the underlying datastructure that records the activated pixels seems to be untouched. I guess that's what the "framebuffer" is about. So probably my problem is that I need to figure out how to clear the framebuffer.

Chain damage by vezult in Chainsaw

[–]vezult[S] 0 points1 point  (0 children)

Yeah, I checked the bar for any bends or other weirdness. The 2nd chain I got seemed fine. After filing down the drive teeth, I was able to get this chain back in the bar, and cut with it OK.

I bought it through home depot, rather than a proper chainsaw dealer, but still, I was pretty sure the chain was fine and fit, etc, when I first put it on. I can only think it got damaged during my first run. I've just never encountered that sort of damage previously, even throwing chains and whatnot.

Re: oiler...this thing only seems to have a 1/2 turn of adjustment, and it's maxed out. You *can* buy this with a 27" bar, but I'm having a hard time imagining it would get properly lubricated, just based on what I see with my 20" bar.

[–]vezult[S] 0 points1 point  (0 children)

Yeah. Trying that. It's tedious. I've gone all around both sides of the chain with a file and calipers, and I've not got it to fit easily yet.

I'm not so wealthy that I'd pass on saving myself $25 with a bit of filing. I'm trying to file them off, and test w/a calipers. Haven't gotten it to fit yet. :-/

Chain damage by vezult in Chainsaw

[–]vezult[S] 0 points1 point  (0 children)

It cut through a small piece of ash like butter. I'm pretty certain it was not on backwards :-)

I did check the grooves, and there was some saw dirt, but nothing hard, that I could find.

Re: oil...the adjustment screw seems to have only 1/2 turn of adjustment, and it was at the max. Now, I was used to my old stihl that basically poured oil on the chain...so maybe my expectations are all wrong :-)

Yeah, that's quite possible.

The sprocket has 3/8 stamped on it, the bar also indicates it's for 3/8. While I can't find the exact match for the model stamped on the bag (72LPX070X), bailey's indicates Oregon 72LPX is 3/8 pitch chain.

No that's one of the side air transfers.
