September 30th

We'd intended flying to the Props, Cop and Rodders show at Cameron Park, but it rained all morning so we drove over instead.

September 29th

The weather's started to look a little odd, so Dad and I went to the airport and flew while we could.

The ADS-B showed cloud moving over the area, so we toddled back quickly.

September 28th

We went to the airport to meet Randy and look at his Bendix, but he was running late.  I took Mum for a flight towards him, and when he passed us (ADS-B - I never saw him) we turned and followed him back to Lincoln.

After lunch, we looked at the Bendix, and I think the problem is the wrong grease - moly rather than the waterproof W-100.  As it's been sitting outside for a while, that's affected it.  We cleaned and regreased it several times and it seems to be working better now.

September 26th

It was overcast this morning, but I fixed a few things around the house and washed the solar panels.

Vic got home from Tahoe in the van, so all is right again in Tillyworld.

September 25th

We pottered around the house again, but did get out to go to the Galleria and Best Buy.

September 24th

We pottered around the house - drilling holes in the map board for my updated weather map and cooking sausage rolls, then went to Glenn and Judi's for movie night, where we watched "One Six Right."

September 23rd

Vic took the van and headed for the hills to (hopefully) get a few nights of proper sleep without being woken up a couple of times a night by Tilly.

The rest of us went to the airport - too late to fly Young Eagles, but early enough to get lunch and see the Airventure / kids' scholarship presentations.

We spent a fair amount of the reset of the day watching the 3D printer.

I did have an interesting interaction with ChatGPT, as I'm too lazy to do the maths.

what percentage would I need to increase the size of a 1/3 cup measuring cup to get to 5oz in a 3D print?

To determine what percentage you would need to increase the size of a 1/3 cup measuring cup to achieve a volume of 5 ounces in a 3D print, you can use the following formula:
Percentage Increase = ((Desired Volume - Original Volume) / Original Volume) * 100
<maths deleted>
So, you would need to increase the size of the 1/3 cup measuring cup by approximately 87.5% in a 3D print to achieve a volume of 5 ounces.

remember volume increases much faster than area

You're absolutely correct; when scaling three-dimensional objects, volume increases much faster than area. To achieve a specific volume increase, you would need to consider the cube root of the scaling factor.
In your case, you want to increase the volume from 1/3 cup to 5 ounces. As mentioned earlier, 1/3 cup is approximately 2.67 ounces. So, you want to scale it to 5 ounces.
Let's calculate the scaling factor:
Scaling Factor = (Desired Volume / Original Volume)^(1/3)
<maths deleted>
So, you would need to increase the size of the 1/3 cup measuring cup by approximately 21.7% in a 3D print to achieve a volume of 5 ounces, taking into account the fact that volume increases more rapidly than linear dimensions.

I'm not worried about the Terminator just yet.

September 22nd

Mum and Dad arrived, and I went and picked them up from the airport.

September 21st

Vic was off work today, and amongst her tasks was getting the van smogged - the rolling road thing was broken when I took it in last week.  It passed :o)

We watched "The Flash."

September 16th

I went to the airport early and flew up to Auburn to met Chris for breakfast - Vic drove up and met us there.  She'd got there early and was in Target when I flew past, reminding her to get to the airport :o)

After breakfast, I flew home and just wasted the rest of the day.

September 13th

Sue and Bob headed off to San Jose in the morning, hoping to get out and about and go to Alcatraz before they fly home at the weekend.

In the evening, the interweb went down.  Boo.  It looked like the modem had taken a dump, so I grabbed the old one and tried that, but it didn't light up either.  I checked the power brick and that was putting out 0v.  I dug through all my crap and found another 12v power brick that I wasn't using, but it used a different plug, so I cut the plug off the broken power brick and soldered it onto the working one, and tada, interweb.

September 12th

Sue and Bob were here visiting Tilly, and it seems that they'd wanted to go through Yosemite but the gates had been closed when they passed.

Sue's been to Yosemite before, so I asked Chris if he'd be up for flying Bob over the valley and he agreed to do so.

They got back not long before I finished work, so we went to dinner again.

September 11th

Sue and Bob showed up on their way from Dallas to San Francisco to see Tilly.  After we got off work, we let Tilly go back to bed and went out to dinner.

September 10th

I printed off a couple of parts for Shane, then went to meet him at the airport.  We flew to Oroville to meet Chris and PJ for lunch - funnily enough we were running early (because I wanted to do my Camp Far West Lake flyby) and so was Chris, so they got there just before we did.

As usual, we disappeared around Beale because there aren't any UAT listener posts out there.

We met Paul (who Chris interviewed for one of his YouTub videos) and his wife Eileen at Oroville, and I gave them some controller mounting boxes I'd printed for them :o)

After lunch we flew back - it was a little bumpier.

Back at the airport, I replaced the grip and the push to talk switch on the plane - believe it or not, I don't think I have anything on the squawk list until the 500 hour service in a few weeks :o)

September 9th

I'd intended to go to the Columbia fly-in with the guys, but Tilly had a bad night, waking us up and keeping us awake several times, so I decided that ~3 hours' flying might not be such a great idea.

Still, I went to the airport and had breakfast at the EAA hangar, then went and pulled the plane apart to move the Garmin GDL39 ADS-B receiver.  I found that the line was juuuust about long enough to put it where I wanted, but that the GPS for the ADS-B transponder was in the way.  That had much more wire on it, so I pulled that out, installed the GDL39, then installed the GPS receiver.  At first glance everything seems fine.  I had wanted to replace the grip on my throttle unit, but that means rewiring and I'd forgotten my forceps to hold things, so I called it a day there and put everything back together and went home.

I met Shane at the house (rather than have him drive all the way out to the airport) and we tinkered around with the 3D print stuff for his helmet.  I like to think we're making progress, and we played with Fusion 360, a more complex 3D modelling software than I've been playing with (TinkerCAD.)

September 5th

I sat and thought about the bracket I printed yesterday and decided it should be at 90 degrees to how I've printed it.  So I redesigned it, thinner, and more like I think it needs to be.  This is a little annoying, as it's not my favoured solution (moving the receiver to a different place) but I don't want to open everything up and find I can't move it, then have to put it back together as it is now so I can work out a bracket.  Still, all ready now - I just need the time and energy to go out and install it.

September 4th

Today was Labo(u)r Day, when Americans celebrate the successes of the union movement by going shopping.

I started the day playing around with the 3D printer - I designed my first 3D thing, a bracket to hold up the ADS-B receiver in the plane, then spent ages watching it print.  It's probably a ways thicker than it needs to be, but it should work.

September 3rd

The forecast for today was terrible, so we'd agreed to drive to lunch to meet up.  Of course, it wasn't all that bad, but we'd all set out by that point.  Still, I went and met Chris, Perry, Randy and Shane for lunch.

September 2nd

Dave and Sam came up to see Tilly and to drop off some Lift for me, then we went to lunch before they headed out to a murder mystery thing in Sacramento.

After that, Shane came over to see Tilly and discuss a couple of 3D printing things for the Team Wendy helmets that we use in the gyros.

September 1st

A new month, so here are the solar stats:

August 31st

Chris mailed to say Rock Monsterz was playing at Cameron Park, so we drove over there after work to watch their practice session.  I'm still humming Kashmir.
