Linear Power Supply for Arduino Projects | How to make a Linear Power Supply

Article – http://www.robocircuits.com/linear-power-supply/

Whenever it comes to any Arduino related project. Everyone needs a power supply to juice up their projects. Some people like me uses ordinary mobile chargers and some likes to use a 9v battery and few go with a lipo battery. But I have a better way!!! Why don’t we just make our own power supply?? Even its cheaper than a traditional mobile charger yet with more flexibility.
Today we are going to make a really small and cheap power supply which will give output of 5v but by replacing only few components we can get 12 or 9v easily. it uses

four diodes
two capacitors
one transformer
1 led
1 resistance
1 7805 ic

If we just change the transformer and the 7805 IC to 7812, we can get an output of 12v.
Let’s learn how to make a power supply step by step.
First of all, let’s clear our aim. So, the main purpose of a power supply is to change 220v AC to 5v DC. It will include 4 steps-
Step 1
Stepping down 220v AC to 9v AC. We will use a transformer for this purpose. Transformer have 2 coils which are in mutual induction with each other. The number of coils in both the coils decide the output voltage.
The simple formula is-
Vin / Vout = Np / Ns
The transformer we are using here will give us an output of 9v AC.
Step 2
Rectifying the AC using Diode. Now we will use a bridge rectifier which consist of 4 diodes in following configuration. It will rectify AC to a rippled DC. Rippled DC is not a perfect DC.
You can see the diagrams for input and output waves.
Step 3
Now we have to filter it. For filtration we are going to use capacitor. Capacitors allow AC to flow through them and Block DC to pass through them. So, we will use a capacitor in shunt with our circuit.
Input and output signals can be seen in wave diagrams.
Step 4
Last step is regulation. For this we will use a 7805-voltage regulator IC. 7805 will give a constant output of 5v. If we use a 7812 IC, we will get a constant 12v output. For a 12v Power Supply we will need to change the transformer to a 12v AC and change regulator to 7812 IC.
Let’s draw a circuit diagram for the same. So here is the circuit diagram for our project.
Then I went to easyeda.com, made the same schematics using the components given in its library. Then I made a PCB design for it. The PCB layout looks cool. I also added a .png logo for my channel.
Next, I get my gerber files using the button given in task bar and downloaded my gerber files. Then I went to jlcpcb.com to order my PCBs, I uploaded my files on the order page. When I was checking the colors, I found a new Matte Black option. I thought I should give it a try. Then I click on add to cart and then clicked on checkout. I selected my address shipping method and paid it using PayPal.
I got them after 8 days. Actually, I ordered matte black as well as green for a little comparison. Matte black color looks awesome. It has a great texture and also for your knowledge it takes 2 extra days for this color. Here is a little comparison between black and matte black.
Then I soldered all the components on the board. And also screwed the transformer on the board. I added an extra wire with a plug.
Then I plugged it in AC socket and the LED starts glowing. I tested it with Arduino Nano and Arduino UNO as well, both worked completely fine.
This power supply is really cheap and looks awesome. The matte black PCB gives it a decent look.

eBike charger / power supply – How to modify them and save money!



#ebike #charger

It’s a little known fact that these Chinese chargers can easily be modified to output up to 108v. Obviously, the limiting factor is the physical ability to deliver an adequate amount of current but, for an emergency, it’s a brilliant solution for range anxiety!

2A charger (240W) which is identical to the silver one I have. You can ramp it up to 84v & 2.8A http://s.click.aliexpress.com/e/bxfcQhjE

4A charger (360W). You can ramp it up to 84v & 4.2A http://s.click.aliexpress.com/e/caPhNpGG

SOLAR PRO-LOGIX PL5100 12/24 Volt Battery Charger + Power Supply



The new PL5100, 12/24V Fleet Charger, is specifically designed to meet the challenges of servicing the multi-battery packs found in today’s Over-the-Road vehicles, implements and agricultural equipment. With a maximum charging rate of 100 amps, it is able to bring even heavily discharged multi-battery packs back to full charge quickly and safely. On today’s tractor-trailers, it is not unusual to encounter battery packs at 80%, 70%, even 60% state of charge. With a 4-battery pack utilizing 150 AHr batteries, 60% state of charge means that a total of 240 amp hours need to be replenished to return the pack to full charge. In this instance, the 100A charging mode reduces your bulk charging time from 3.4 to 2.4 hours, a 30% improvement vs. a 70A charger. During a regularly scheduled service event, this time savings could mean the difference between getting the pack back to full charge or only partially recharging it. Increasingly, electrical system repair and diagnosis requires the supply of steady power to maintain system voltage throughout the repair event. The PL5100 features a power supply mode that allows the operator to select a target voltage level for the vehicle’s system and the charger will supply current as needed to hold system voltage at the target level. This mode is supported for both 12V and 24V operation and allows the operator to select the desired voltage in 0.1V increments (13.3-14.9V, 100A in 12V mode; 27.2-29.9V, 30A in 24V mode).

HURRICANE SUPPLY KIT: How to prepare an emergency kit | 10News WTSP



Here’s how to make a hurricane emergency kit. 10News Chief Meteorologist Bobby Deskins explains what critical supplies you need in your emergency disaster kit for hurricane season.

You’ll want to have enough non-perishable food, medicines and water to last each person in your family for at least one week. Don’t forget cash – ATMs won’t work if the power goes out – and batteries for cell phones, radios and other devices.

Here are several items you’ll need:
• Water – at least 1 gallon daily per person for 3-7 days; also fill the bathtub and other containers; sports drinks are good to fend off dehydration
• Food – at least enough for 3-7 days; non-perishable packaged or canned food; juices; foods for infants or elderly family members; snack foods; food for special diets
• Non-electric can opener
• Cooking tools, fuel
• Paper plates and cups, plastic utensils
• Bedding: blankets, pillows, etc.
• Clothing
• Rain gear
• Sturdy shoes
• First aid kit, medicines, prescription drugs
• Toiletries, hygiene items, moisture wipes, dry shampoo
• Flashlight, batteries, lanterns
• Radio: Battery operated and NOAA weather radio
• Telephones: Fully charged cell phone with extra battery; chargers; traditional (not cordless) telephone set
• Cash (with some small bills) and credit cards: Banks and ATMs may not be available for extended periods
• Important documents: Place in a waterproof container or watertight resealable plastic bag: Should include insurance, medical records, bank account numbers, Social Security card, prescriptions, etc.
• Tools: Keep a set with you during the storm
• Gas: Fill up your vehicles several days before landfall is expected; Gas stations could lose power during a storm and supply trucks may not be able to reach the area
• Pet care items: Proper identification, immunization records, medications, ample supply of food and water; a carrier or cage; muzzle and/ or leash
• Bleach without lemon or any other additives
• Fire extinguisher
• Mosquito repellent
• Keys
• Toys, books and games for children
• Duct tape
• Cell phone charging stations — locations where you can charge mobile devices
