inverter generators

The camera obscura was an important scientific discovery back in ancient times. It helped us understand that light travels in straight lines, as eloquently demonstrated by 11th-century Arab scientist Alhazen. He discovered that a single ray of light beaming through a tent produced an inverted image of the scene outside.

You can recreate the revolutionary experiment yourself with a window, some cardboard, and a hole-poking device of your choice. We recommend a trident, as we always do.

Slap some cardboard slabs over the window and cover all other light sources, then jab a hole in the cardboard (you can make it smoother or rougher to adjust resolution):

Wait for your eyes to adjust and enjoy the free acid trip. Your room is now a rudimentary camera, generating an inverted image of the scary world outside. It’s reversed because the light beams reflecting from higher objects like trees or buildings travel down diagonally through the makeshift lens, and vice versa for objects down below.

Do You Want To Set Your Hand On Fire? 6 Fun Science Tricks

My power came back after three hours. It is extremely unusual to lose electricity that long where I am. Power lines are buried which helps avoid outages. Where I grew up the wires were strung from poles through the back yards. We lost power several times every summer. As a kid I thought that was fun. As an adult I don’t share that same excitement.

My basement didn’t get any water damage. That’s a relief. This is a good warning that I need to get serious about a backup battery. As I did some research I decided I’d rather have an inverter-generator.

Yes, the sump pump battery would kick in automatically. I would need to be around to start up the generator. However a generator could be really useful if we lost power for days. With plenty of good neighbors and family around I think I’d be OK getting some help if I was out of town and power was out for days.

These ones here will run a refrigerator or a space heater. They’re also small enough to take car camping. Any of you have an inverter-generator for emergencies?

Basics of the Basics of Sewing: The Lingo

Here I am back again to continue on with Basics of the Basics of Sewing. Click here to see the previous entries.

This week is all about the lingo of sewing and I am here to explain what a bunch of the terms used in patterns mean. The last two posts regarded sewing machine parts, and tools, so those won’t be included today.

Once again, I am a mostly self-taught seamstress, so I won’t include everything under the sun, only what i think is essential, you can always message me if you have any questions!

Alter - to change a pattern or garment to different sizing or fitting needs (ie changing lengths, sizes, adding darts)

Backstitch - used at the beginning and end of a seam to make it more secure and permanent, see sewing machine post for detail

Baste/Basting - a long or large stitch done without backstitching to create a temporary seam that will be removed later (example: putting in a zipper)

Bias - runs diagonal to the straight grain of a fabric, it is the stretchiest part

Bias tape - can be bought pre-made or made yourself, used for bindings facings or where there is a need to accommodate for stretch and curves

Bodice - the part of the garment that is from shoulder to waist

Casing - a fabric pocket or envelope where you would insert elastic or a drawstring

Dart - a v shaped seam that allows for more fullness, more on that later

Drape - the way the fabric hangs

Finish - to finish an edge is also what I call a lazy hem if used for hemming, turn the fabric in a ¼ inch, stitch and zigzag raw edge.

Fold line - the edge of the pattern that should line up with the fold in the fabric, be wary of which way the bias is when using a stretchy fabric.

Fusible - usually talking about interfacing, you can iron it on due to a heat activated glue in it

Grain - runs parallel to the selvage

Inseam - seam inside of pants that runs along the inside of the leg to the crotch

Interfacing - used in between layers of fabric to provide stabilization and help form the garment (especially in collars)

Lining - used to finish the inside of a garment and hide seams, eg. satin lining a prom dress

Notch - shown on pattern with a dark diamond. generally it sticks outward and is used to properly align pieces

Notion - any item used for sewing other than fabric and the machine (ie. buttons)

Overlock - zigzag stitch or surging to finish the raw edge

Pivot - to leave the needle in the fabric while raising the presser foot and moving the fabric, used for making corners and other sharper turns

Pleat - fold in fabric, generally inverted, more on that later

Pre-shrink - to wash and dry fabric before using it to prevent your garment from drastically shrinking afterwards

Press - to iron seams or other parts of a garment

Raw edge - edge of fabric that is not finish and would fray

Right side - the right side of the fabric is the side with the design, sometimes it is difficult to tell, this side will be the part you see while wearing the garment

Seam - what is made when two pieces of fabric are sewn together in along a line

Seam allowance - length between edge of fabric and stitching line generally 5/8 - ¼ inch

Top stitch - functional or decorative stitch done when a finished edge is pressed under and then sewn into place, more on that later

Wrong side - the opposite of the right side

Alright, so those are just a few of the more essential sewing terms, let me know if you have an queries. Don;t forgot to enter my giveaway, and follow me to keep up with BotBoS.

Next week we will actually get sewing! Get excited!
