Solar Charging Station

I made this solar charging station to connect to my solar power system. The solar panel is on the porch roof outside my bedroom, and it is connected to a charge controller and a marine battery. I added an extension cord to reach a shelf in the hallway so that it's easier for my parents to plug in their phones.

I rescued the car plug from a parking lot and bought the switch from a Habitat for Humanity Re-Store. Having the switch prevents power from being wasted when the charger isn't in use. The light tells us that the charger is connected to the battery and power is available. It makes more sense to charge phones during the daytime when the most power is being generated, but my parents prefer to charge their devices overnight instead.   

Reusing Glass Bottles with Pour Spouts

When I first started making my own soda syrups, I stored them in plastic squeeze bottles. The disadvantage of using plastic is that even after washing in a dishwasher, they retained the smell of the previous syrup. I decided to use glass bottles instead because they don't have that problem. The cheapest way to find glass bottles is often full of soda. 

I saved bottles from different drinks so now I have a collection of bottles that look unique to help me remember which syrup is in each bottle without having to label them. I have green, clear, brown, and spiral bottles. There's also one I found in the woods that's an antique beer bottle. It's definitely older than 1995 because that's when the fence was installed. It's perfect for root beer.

Of course, the bottle I found outside needed to be cleaned and disinfected. I soaked it in bleach and then scrubbed it clean. After using a thin brush that was designed for cleaning straws, I decided to buy a bottle brush. I modified a baby bottle brush to fit through the mouth of the bottle and reach the bottom. The original handle was thick plastic, so I cut it off and replaced it with a long skinny bolt. Later I unscrewed it and welded on a t-handle.

The soda bottles don't have reusable lids, so I bought pour spout lids that fit. Here's my Amazon Affiliate link for the spouts: https://amzn.to/3REzUU5

I also made a special tool to remove the spouts. It's kind of like an open ended wrench to pry the spout out evenly from both sides without damaging it. 

Greenbriar- Edible Wild Plant

 Greenbriars (smilax) are a wild edible plant in central Texas. The tip of new growth, especially in the spring, looks a bit like asparagus. It tastes kind of like a cross between green beans and asparagus.

Identifying the right plant is very important. Smilax has lots of thorns, unlike the poisonous Carolina Snailseed Moonvine. I have two different species of greenbriars in my yard. The one with dense needle-like thorns tastes bitter, while the one with normal thorns tastes ok. Only the new growth is tender enough to eat. It's also important to harvest from an area without herbicides or pesticides. 

 Unless we are pruning back a whole plant that's in the way, I like to harvest just a little bit each day and then store the shoots in a cup of water in the fridge. Once I've collected enough to cook with, I wash and chop them. They are good in scrambled eggs, omelet, or vegetable stir fry.

Vanilla Pudding Brulee

 

Ever since I got my propane torch, I have wanted to make creme brulee. I've never had creme brulee and I don't know how to make the complicated recipe with eggs and other ingredients. So I decided to make vanilla pudding brulee instead. I started with a store brand boxed pudding mix and added milk, cream, and a dash of cinnamon. After mixing, I spooned the pudding into about 6 individual metal containers and stored them in the refrigerator. When I was ready to serve the pudding, I sprinkled sugar on top and melted it with my torch. 

Automatic Foaming Soap Dispenser With Dilution System

My automatic soap dispenser has been through several versions. There was the regular automatic dispenser, the rainbow soap version, and now the foaming soap dispenser.

Unfortunately, keeping a bottle of diluted soap for the foaming dispenser was not a good idea. The watery mix, even with soap, ended up growing moldy. So I decided to keep the full concentration of soap in the bottle, and dilute it on demand instead. To do this, I used the pump from the rainbow version, with one channel pumping soap and the other five channels pumping water. 

It uses the same technique as my tea robot, with electrodes to control the mixing pump. The mixing pump only runs when the dispensing pump runs, so there's no chance of overflowing.
