Bluetooth Speakers

Bluetooth Speakers

Why are they called Bluetooth speakers? 

Bluetooth was named after a tenth-century king, Harald Bluetooth, King of Denmark and Norway.

He united dissonant Danish tribes into a single kingdom. The implication is that Bluetooth unites

communication protocols. Bluetooth speakers get their name because they play music

transmitted from a Bluetooth enabled device.

Who invented them? 

Jaap Haartsen

What can Bluetooth speakers do?

Bluetooth is a wireless transmission technology that's used for device-to-device connections,

for example, between your phone, tablet or laptop and Bluetooth equipped speakers or

headphones. Bluetooth can also be used to transmit data between two devices.

Bluetooth doesn't transmit well through walls or around corners.

Why did he invent them?

Bluetooth was developed by a consortium of companies to create a short-range wireless

standard. The goal was to offer security, low power consumption, high speed

(relatively speaking), and compatibility between any Bluetooth enabled device.

In addition, Bluetooth can pull some serious ad-hoc networking stunts.

What have I ever learned and enjoyed while making a Bluetooth speaker? 

I enjoyed all of it because I use to do a lot of woodwork with my Poppa.

mocha fudge brownie with Kahlua sauce

mocha fudge brownie with Kahlua sauce

for brownie:

375g dark chocolate

200g butter

2 cups of sugar

3 eggs

3 tsp sweetened coffee essence

1 1/2 cup flour

preheat the oven to bake at 180c. melt chocolate and butter together. mix melted butter with the sugar
eggs and coffee essence until smooth. mix in flour, pour into 20X30cm sponge tin lined with baking paper
and bake at 180c for 35-40 mins. cool in the tin for at least 20 mins before removing

Kahlua fudge sauce:

375g dark chocolate

300ml cream

1-2Tbsp Kahlua or sweetened coffee essence

Stir ingredients together over a gentle heat until melted and smoothly combined

It tasted a little bit of what I think is coffee and smelled like coffee apart from that just seems like a
normal brownie. I enjoyed melting the chocolate and I was confident in making this because I have been
baking for a long time.

We could not find Kahlua or coffee essence at our local shop so used substitution of instant coffee made up with hot water

My Aunties fish

My Aunties fish is called Louie, he is a Betta fish also known as a Siamese fighting fish

Why do Siamese fighting fish have to live alone?
Bettas, unlike other species, are not schooling fish and will fight with each other, regardless of gender. Bettas prefer to swim alone and also need a comfortable place to hide. Louie has a diving helmet ornament to hide and feel safe in

What do we feed Louie and how often? 
We feed him floating pellets 2 - 3 times a day.

How often do we test the water and what for? 
Once a week we test the water for ammonia, nitrite, nitrate, and pH.

How do we clean the tank?
We use a magnetic glass cleaner to clean the sides of the tank. We then take out any ornaments and fake plants that need cleaning and use a toothbrush which is just for this. Then a net is used to fish out any bigger bits of gunk. After this, we use a water siphon hose to do a 50% water change. Usually, only a 25% change would be done but today some of the water levels were off. Clean ornaments are put back into the tank and then the tank water is topped back up. This water has got primer and water conditioner in it to treat the water for any chlorine or toxic substances.
