Leia Belt Tutorial from Jedi-Academy
http://www.jedi-academy.com/leia_anh_belt.html


My poor attempt at how I made this dress
I made the dress without any commercial patterns since it's easy enough.

I laid out 9 yards of fabric double folded on itself (4 layers) and then folded it in half from neck to floor hem (so that the right and left sides would be mirrored).  

I then drew out the shape of the dress and sleeve.  I pinned all the layers together so there wouldn't be any shifting when I was cutting, and then cut it out.  

I then opened it all up, pinned the two really long layers together (NOT at the neck though - you need this open to turn the dress right-side out), and sewed all the edges.  

The dress was then turned right-side out through the neck opening, and the seams were ironed flat.

I then laid out the dress folding it along the top of the sleeves (so there wouldn't be any seams on the top of the dress) so the sides and floor hem matched up.  I then pinned it in place leaving the slits on the sides open and sewed it together.

The collar was easy, it was made as long as my neck is around (12.5"), and about 7" high, fodl the collar in half length-wise and sew the ends (short sides) shut.  Turn this right-side out and iron flat.

The 'hood' was made about 16" wide and 36" long.  I did a rolled hem along the long edges before sewing it to the dress.  
I then gathered the short ends to about 4" in length and sewed them in place along the edges (to keep the gathers from moving while sewing it to the dress).

I stay-stitched the edge of the neckline on the dress and then layered the dress, hood, and collar in place.  These were pinned and then sewn.

For the gathers in the front of the dress I used a smocking stitch to keep them in place.  These are hidden under the belt while the dress is worn.

EDIT: Version 4 of the dress.  The top and bottom sections have a waist seam because my arms are too long to use the fabric selvage edge to edge.
There is elastic sewn to the waist to give instant gathers, this is all hidden at the natural waist by the belt.  This version fits so much better than the old one.  The sleeves are finally long enough and the hem is at the perfect length after blousing the waist over the belt a little.

The belt was made using the Obi-Wan's Jedi Academy tutorial (see link above).

The Orchard
2. The Orchard  (Take the camera for a walk ...)
Hi,
My name is Heinz and I moved in here mid January. I am a photographer and took my camera for a walk around 'The Orchard' complex shooting a few pictures here and there, porches, doors, exterior of windows, plantings, and various decorations offered to the observant eye.

When you click on a photo a larger version opens up, or you can select the slide show and it lets you wander through the complex one picture at a time.

I invite you to take the walk with me through the pictures I shot on February 25, 2015 shown here. If I captured something of yours, or merely something you like, you are free to download it. If you need a high resolution digital copy or prints leave a message here or contact me through the E-mail address below.

If you would like to improve your skills of taking photos, or photo editing let me know at:

HeinzPhoto@aol.com

we can work something out privately or through the Activities Director if sufficient interest justifies it.

UHF M4 (9.5x9.0) 4-Bay+FLAT Grid at 16"
7. UHF M4 (9.5x9.0) 4-Bay+FLAT Grid at 16"  (27 Oct 2013)
UHF M4 (9.5"x9.0") with Flat Screen Grid Reflector analyzed using 4nec2.
Dimensions for Bowties are for mclapp's M4 using AWG8 per his website drawings.
There was no attempt was made here (yet) to jointly optimize Bowtie & Reflector dimensions.

Better for HiVHF: 40-in x 40-in Screen Grid (1"x2") Reflector located 16-in behind 4-Bay Bowties,
but higher SWR on lowest UHF Channels and Gain on higher UHF channels moves to +/- 25-deg,
resulting in reduced Forward Gain.
[An improved design should be investigated, reducing these UHF degradations.]

UHF Raw Gain = 13.7 to 14.5 to 9.8 dBi, F/B & F/R Ratio Min = 10.9 dB and SWR (300-ohms)
up to 4.5 on Ch14 and under 2.7 on Ch17 and above.
Hi-VHF Raw Gain = 8.0 to 7.7 dBi, F/B & F/R Ratio = 13-15 dB and SWR (300-ohms) under 3.2.

ERRATA (27Oct2013): Corrected labels and narrative (charts remain the same).
Separation between Reflector and Bowties for the two alternatives is actually 16-in (vice 17-in).
When defining nec file names, I overlooked -1 inch offset in the Bowties.

HiVHF+UHF 2-Bay+Loop - NO Reflector
8. HiVHF+UHF 2-Bay+Loop - NO Reflector  (27 Jan 2015)
Hi-VHF + UHF 2-Bay Bowtie plus Hi-VHF Rectangular Loop Resonator analyzed using 4nec2.

Two versions were analyzed: a) mclapp M2 (9.5x9.0) sized 2-Bay plus Rectangular Loop and b) Re-Optimized 2-Bay plus Rectangular Loop.

a) mclapp M2 (9.5x9.0) sized 2-Bay plus Rectangular Loop, where Loop is in the same plane and always OUTSIDE the 2-Bay.

b) Re-Optimized 2-Bay plus Rectangular Loop, with 0.5-in Offset between them to avoid overlapping wire collisions.

Horiz-Stack 2xFF4 + DoubleAng Refl - RFC
9. Horiz-Stack 2xFF4 + DoubleAng Refl - RFC  (3 Jun 2014)
UHF+Hi-VHF HFF8, a Horizontal Stack of 2 ea Free-Form 4-Bays (FF4) with Double Angle Reflectors
(each 48" H x 36" W using 2x2-in Grid) were analyzed using 4nec2, presuming they are driven separately.
FF4 dimensions are sameas found for the Optimized version with
a Variable Double Angle Reflector.

Here the usual Horizontal Stacking approach is used, with Equal Length Coax to a (ZERO LOSS) RF Combiner.

Initially, 4nec2 Parameter Sweep plotted Raw Gain versus Horizontal Stacking Distance.
Since SWR plots were always excellent across the UHF Band, they are not shown here.

Performance was slightly "Better" at THREE notable Stacking Distances:
34.821-inches (NO GAP, Continuous Reflector), 35-inches (Metal-to-Metal about 1/4-inch)
and 51-inches, which are analyzed below.
There were notable Stacking Distances further out, but none were particularly "Better".

Although the differences are only a few tenths of a dB, Stack Distance = 51-inches was just
a bit "Better", esp. Hi-VHF, than at 35-inches.  The wider Separation may also be slightly
"Better" at combating Multipath Fading due to the reduction in Statistical Correlation
between the two Antenna signals.  The "NO GAP between Reflector" alternative was slightly worse.

===========================================
a) Horizontal Stacking Distance (4-Bay Center-to-Center) = 34.821 inches (NO GAP between Reflectors).

UHF Raw Gain = 17.2 to 19.7 dBi, F/B & F/R Ratio Minimum = 16.4 dB & SWR (300-ohms) under 2.1.
Hi-VHF Raw Gain = 10.4 to 9.9 to 10.3 dBi, F/R & F/B Ratio Min = 16.4 dB, although SWR (300-ohms)
under 20 dB is EXCESSIVE, which may or may NOT be an issue in any particular situation.

===========================================
b) Horizontal Stacking Distance (4-Bay Center-to-Center) = 35-inches (0.18-in GAP between Reflectors).

UHF Raw Gain = 17.3 to 20.1 dBi, F/B & F/R Ratio Minimum = 15.8 dB & SWR (300-ohms) under 2.1.
Hi-VHF Raw Gain = 10.5 to 11.7 to 11.9 dBi, F/R Ratio = 11.6 to 14.9 dB, although SWR (300-ohms)
= 24 to 15 dB is EXCESSIVE, which may or may NOT be an issue in any particular situation.

===========================================
c) Horizontal Stacking Distance (4-Bay Center-to-Center) = 51-inches (16.18-in GAP between Reflectors).

UHF Raw Gain = 17.6 to 20.3 dBi, F/B & F/R Ratio Minimum = 14.2 dB and SWR (300-ohms) under 2.1.
Hi-VHF Raw Gain = 13.5 to 11.4 dBi, F/R Ratio = 9 to 19 dB, although SWR (300-ohms) = 29 to 22 dB
is EXCESSIVE, which may or may NOT be an issue in any particular situation.

Hi-VHF Hourglass Loop
13. Hi-VHF Hourglass Loop  (30 Nov 2012)
Hi-VHF Hourglass Loop analyzed using 4nec2 after finding "best" dimensions using nikiml's Optimization
Scripts.  Based on UHF Hourglass Loop posted by oneolddude in www.digitalhome.ca forum:
1/4-in O.D. Elements and Reflector Rods.

NO Reflector Rods (Optimized H=41.75-in, W=34.5-in & Feedpoint Gap=2.5-in):
Ch7-13 Raw Gain = 5.3-6.1 with Excellent SWR under 1.6 (using Quarter-inch Copper Tubing).
Provides about 4 dBi Raw Gain on Ch2-6 and FM Band, but SWR is excessive.
Also provides some Raw Gain with acceptable SWR in UHF Band, but only over mid-band frequencies.

Charts assume Quarter-Inch-Copper, e.g. Tubing or RG-59 braid shield (no need to strip insulation).
Much smaller size AWG12 wire has NO effect on Gain and only increases SWR to 2.0,
so feel free to use even smaller wire sizes.

Add 15 Reflector Rods (Optimized Width, Rod-Rod Separation & Separation from Hourglass):
Ch7-13 Raw Gain = 9.7-10.05 dBi with SWR under 3.1 (using Quarter-inch Copper Tubing).  
Reflector Total Height = 68-in x Width = 56.5-in.
Excellent Front/Rear (hemisphere) Ratio = 32-34 dB with Front/Back (toward 270-deg) = 20 dB.
Provides some Raw Gain on Ch2-6 and FM Band, but directed to the REAR and SWR is excessive.
Not suitable for UHF Band: poor SWR & Gain toward Diagonals.

With 15-RR, provides Gain nearly as much as Winegard YA-1713, except sidelobe nulls moved
to sides and consistently EXCELLENT F/B and F/R Ratios.

EDIT (4Jun2013): Added Hourglass with 11 Reflector Rods and with 7 Reflector Rods to illustrate
how much reduction to expect in Gain and F/R Ratio.  Also note that Reflector Height and Width are
significantly smaller.

EDIT (6Jun2013): Added Comparison Chart showing improvement in Raw Gain & F/R Ratio with more RRs.

EDIT (14Dec2014): Added 5RR and 3RR versions.
