The moving, rotating and lighting Mini-Brush

In OUR previous electronics projects WE were tinkering around with vibration motors and flashing LEDs, well we will continue on the same schema to get a bit more soldering practice and to discover ALSO the use of heat shrink tube, accumulators and drinking straws. This is ALSO a soldering exercise with some fun, and knowledge acquirement as usually in my tutorials. WE will learn also about accumulators, rechargeable batteries. Using accumulators instead of batteries will save us a lot of money and it is ALSO providing LESS RECYCLING! 😉 WE do something GOOD for the nature <===> Sustainability!!


OHM’s Law, resistors and LEDs

.

.

As WE are using a 9 Volts accumulator (rechargeable battery) this time together with a LED, WE need to put a resistor in series to the LED to protect it.As

Practical Tip: LEDs are transparent, so the Cathode (Minus) looks always a bit larger as the Anode (Plus).

When working with electronics WE need to learn a bit theory and mathematics, BUT DON’T worry, it is very easy! First of all which is mandatory, is the “OHM’s Law“. YOU DON’T need to calculate! 😉 There is an online calculator who will do the job for YOU! Click the image below please to access the online calculator and play a bit around with it to get used to it, have fun.

..

Click the image please to access the online calculator

.

Let us make OUR calculation for the resistor: WE have a power supply of 9 Volts and the used LED has a maximum of 3 Volts while its current is 20 mA (milli Ampere). Thus meaning: 9 Volts – 3 Volts is 6 Volts which need to get dropped away from the LED to NOT destroy it! SO, on the resistor 6 Volts need to get derived away from the LED. Let us NOW convert the 6 Volts to milli Volts which gives us 6,000 mV. AND as R = U/I <===> 6,000 divided by 20 is 300! The resistor MUST have a value of 300 Ω, next standard value is 330 Ω!

WHEN YOU use the above online calculator YOU SHOULD give the values in VOLT and in Ampere; or WE have 20 mA which is 0,020 A. Check the online calculator below please:

Working with heat shrink tube

[START text from Wikipedia] Heat shrink tubing (or, commonly, heat shrink or heatshrink) is a shrinkable plastic tube used to insulate wires, providing abrasion resistance and environmental protection for stranded and solid wire conductors, connections, joints and terminals in electrical work. It can also be used to repair the insulation on wires or to bundle them together, to protect wires or small parts from minor abrasion, and to create cable entry seals, offering environmental sealing protection. Heat shrink tubing is ordinarily made of nylon or polyolefin, which shrinks radially (but not longitudinally) when heated, to between one-half and one-sixth of its diameter. [END text from Wikipedia]

Watch the video below please to see the How-To to work with heat shrink tube.

Optimizing the design

I first started to make a normal cabling and the mess I saw didn’t make me feel proud and comfortable, there was something embarrassing! I looked around on my working bench and I discovered some drinking straws which I bought (can’t remember for what, bought them as I was feeling to do so…). I took one and was plying it and suddenly the idea was there to hide the cables inside and WHY NOT to incorporate a super bright LED: the idea was born 😉

In previous blog post (tutorial) WE used a vibration motor from an old smartphone and we were learning also about the How-To about a vibration motor is working; it is about “Unbalance“. This unbalance is normally unwanted for motors, but for vibration motors it is a MUST. The motor we used was a 3 Volts motor and very small. In THIS NEW project we will use a 9 Volts DC-Motor and we will create from a normal motor a vibration motor with a little trick.

We will use a square nut and saw it in the middle, then taking the hot glue pistol and gluing it (one half) on the shaft of the 9 Volts DC-Motor.

9 Volts DC Motors are actually very cheap, check below please:

Let us have a look on the unbalance and vibrations motors

A vibrating motor is essentially a motor that is improperly balanced. In other words, there is an off-centered weight attached to the motor’s rotational shaft that causes the motor to wobble. The amount of wobble can be changed by the amount of weight that you attach, the weight’s distance from the shaft, and the speed at which the motor spins.

VELCRO.

.

As you can see there is NOTHING special; we just put five (5) elements (4 flashing LEDS, a vibration motor) in parallel. The motor will get fixed with hot glue on the bottom. And we have a switch to switch on/off our circuit. As battery we use a 9 Volts battery which will get fixed with “VELCRO” on the bottom.

Learn more:

Calculating the resistor value with a 9 Volts battery and knowing that the flashing LEDs will be 3 Volts and consuming 20 mA. SO: 9-3=6 Volts which will get needed to take away from the LEDs. Check below please:

The shown value is 300 Ohms, but that is NOT a standard value. We will use a 330 Ohm resistor, as it is a standard value.

The tools needed

Check below please WHAT the tools are that you will need for this project. The small saw is needed to cut out a small piece of 55 x 45 mm from the stripboard. That part is needed for soldering the resistor and the switch and is used to make the necessary connections to the other parts.

. Electronic-Arts: JOHNNY the ski-man .


Maker-First Steps in Electronics-Soldering Learning

When WE start with electronics on the beginning we can work with so-called “Breadboards“(see photo below please), but soon or later soldering will become a MUST and an habit! SO, the BEST WE can do is to GET some PracTICE with soldering; in this tutorial we will make a bit “Electronics-Art“. WE will use already known electronic components such as resistors, stripboard parts (we will need to saw and rasp…),  a LED and an IC (Integrated Circuit), a NEW component. OUR project will ONLY serve as soldering PracTICE as there will be NO function of the electronic used, SO the IC could be ALSO a damaged one (useful recycling) 😉

As YOU might have seen in the image of “JOHNNY the ski-man“, some resistors are BIGGER then others! WHY and what is its meaning!? Well, WE have to go back to “OHM’s Law“, as BIGGER resistors in size are, as MORE POWER they can dissipate; I used 1/2 Watt and 1 Watt resistors. Please check below.

As the stripboard pieces are rectangular on the edges they must get rounded as well with the rasp, see pic details please.

Solder together now the three rows on the top of the stripboard as shown in image, this will give a bit weight to keep the balance once the other electronic components are soldered.

SO, the hardest job is done now! UP to solder the electronic components, but where to start!? Start first with the soldering of the diode (1N4007) on both skis, followed by soldering the small resistors, check pic please.

.

.

.

.

.

A little exercise: WHAT are the values in OHM (Ω) of the resistors used (check pic, please)? Hint: if YOU don’t remember how the code is working, check here <===> http://www.allaboutcircuits.com/textbook/reference/chpt-2/resistor-color-codes/ <===> and/or here for an online calculator <===> http://www.allaboutcircuits.com/tools/resistor-color-code-calculator/.

BTW: for OUR project it doesn’t matter which value the resistors have as they are used ONLY for the soldering PracTICE..

Concerning the PracTICE about soldering check <===> https://www.kemo-electronic.de/en/loetkurs.php?page=1 <===> A GREAT step-by-step guide.

Maker-First Steps in Electronics, the basics

Maker-First Steps in Electronics, the basics

.

first-steps-on-electronics-fritzing-layout-strip-board-print-out-sheet

.


Where to start?

platine-hartpapier

Strip-Board

I propose to work with system when WE use strip-boards; thus meaning: preparing them ALL the same way. Any electronics project will need a power supply, so WE will start with the power supply which will mostly be a 9 Volt battery. WE will use the outside strips to connect them to plus and minus and WE will ALSO provide a diode (1N4007) to protect against polarity reversal. As a newbie in electronics this might be the best way to protect you to destroy the electronic parts if + and – would get reversed 😉 With normal rectifier diodes the power supply voltage will typically drop by 0.8 volts. WE will have then ONLY 8.2 Volts which is enough in most cases.

WE will solder also a PCB-Connector (Printed Circuit Board Connector) where we can feed the strip-board with the power supply.

.

SO, as WE will solder a bit, it will be also a soldering training before we start on more serious projects later 😉

Check below please how the finished project will look, which we will discuss in detail on the How-To. WE use a 100 mm x 75 mm strip-board (CONRAD 529531 – 62  for 2,19€).

.

First steps in electronics

Necessary material

.

screw-terminal-2-pins.

.

In above image I used a 2 pin screw terminal from CONRAD (1192188 – 62) for 0,28€ and for the wire I choose from a “Wire Kit from Velleman” (60 m from different colors).

  • full core, 0.2mm²
  • colours: 5 metres : white / blue / brown / green / yellow / orange / grey / violet + 10 metres : black / red
  • external diameter: 1.4 mm
  • max. voltage: 60 V
  • max. current: 4.3 A
  • PVC insulation
  • tinned CU
  • AWG24

.

abbiegevorrichtung.

To make sure to have proper bent edges; I suggest to bend the diode (1N4007) over the left-hand side shown “Wire Bender” (CONRAD 425869 – 62  at 3,29€).

 

.

.

First start to solder the 2 pin screw terminal in the middle of the strip-board, followed by the diode (1N4007). Now measure the distance and cut the wires. For the red wire (Plus) it will be 4 cm (3 cm distance), the blue wire (Minus) will be 6 cm (5 cm distance). Take the electronics cutter and strip off o,5 cm of the insulation at each end and bend it. Put it into the holes in the strip-board and solder it. P.S.: WE will use the red wire for the Plus (+) and the blue wire for the Minus (-) of the power supply; that are internationally conventions in electronics. Sometimes for the Minus (-) is also used the black color (see 9 Volt battery clip).

When WE want to start with electronics there is a little bit theory to learn as well; in electronics there are special symbols who get used in schematics. Any component (even a battery) has its own symbol. In the following tutorials and projects, WE will learn by easy step-by-step WHAT they are and HOW to make OUR PracTICE (to GET used to it…) with them. I am certainly NOT a friend of learning by heart, BUT symbols need to get learned that way to understand schematics of electronics!

first-steps-on-electronics-fritzing-layout-strip-board

.

.

resistor-color-chartAs You have remarked, I added ALSO a resistor and a LED (Light-Emitting Diode); the red (could also bee a green one) LED is lightning when the power supply (9 Volt battery) is connected. SO, YOU might solder the two components (330 Ohm resistor and LED) as well, not mandatory BUT it will give YOU a bit more training on soldering and alerts YOU to NOT solder when it is on!! NEVER work on whatever project with connected (switched on) power supply <===> Safety first!

WHY has the resistor a value of 330 Ohm?

In above example we used a 5 mm red LED with this characteristics: 2.25 Volt and 20 mA current (that’s the maximum values which DON’T have to become higher otherwise the LED will get destroyed) and as power supply we use a 9 Volts battery.  WE will use the “Online Calculator” to calculate the value of the resistor. First let us do some mental calculation, there WE DON’T need any calculator. WE have a 9 Volts battery and the LED will have maximum 2.25 Volts, so “9 V – 2.25 V = 6.75 V” which needs to get taken away from the LED to avoid destruction.

THAT value of 337.5 Ohms doesn’t exist! Resistors are manufactured by following <===> In 1952 the IEC (International Electrotechnical Commission) decided to define the resistance and tolerance values into a norm, to ease the mass manufacturing of resistors. These are referred to as preferred values or E-series, and they are published in standard IEC 60063:1963. These standard values are also valid for other components like capacitors, inductors and Zener diodes. The preferred values for resistors were established in 1952, but the concept of the geometric series was already introduced by army engineer Renard in the 1870s.

By checking the below link, WE will see that the closest value is 330 Ohm. BTW: The symbol for “Ohm” is “Ω“; SO, we write 330 Ω. Tip: You find it in the “Special Characters” in any editing software.

In the above website is a video integrated which explains very well about the How-To of that norm, give it a try.

framing-in-educationMY experience described in ONLY some phrases: Give the LEARNers, students (whatever age) the freedom of LEARNing without squeezing THEM into a FRAME and concentrate on guiding them as a coach by analyzing THEIR behavior and show them the How-To to become self-directed learners, autodidacts. SHOW THEM ALSO up from the beginning WHAT THE <===> LEARNing Path <===> will be with design of it and explain THEM that they could design themselves it with a short introduction on the How-To. THEY will learn the ICT-PracTICE which will help them once out of the <===> #SchoolCocoon <===> to be ready for Life-Long LEARNing and to be able to adapt very quickly in the workforce! WHEN YOU show the LEARNers, students <===> WHAT the profit is for THEIR private life <===> YOU will engage them very quickly 😉 AND DON’T teach THEM more as necessary, propose them some links to go further ONLY for those who want!!

WHAT’S my message and WHY did I create this blog post!?

Well, I will encourage all youth and also adults, seniors, oldies to become <===>Life-Long LEARNers <===> and staying Up-To-Date with their knowledge, especially concerning their skills in ICT, called NOW <===> #eSkills <===>! In the modern world YOU will change YOUR job probably +/- 12 times in YOUR working career, it is very rare to stay life-long in the same job and/or same company!!! SO… The workforce is looking for people with ICT skills which YOU mostly didn’t learn at school, right!? 

Bring in YOUR kids to such creative makerplaces WHERE THEY can develop (and perhaps parents as well…) THEIR creativity and GET interested in something WHICH could boost THEIR interest into ICT in their future 😉

YOU won’t have (mostly) the time to learn by visiting courses, right!? START to become Life-Long LEARNers by LEARNing on YOUR OWN pace, by becoming <===> Autodidacts <===> Self-Directed LEARNers. YOU are able to, I did it, so can YOU!? 😉

I found a job because of my ICT eSkills and I am STILL LEARNing on a daily base routine for being Up-To Date with my <===> Professional Development <===>, even being retired NOW! THE pleasure of LEARNing!

I did THE <===> ICT PracTICE <===> and THAT’S WHAT the workforce needs!!!


 Due to my eSkills I could share my knowledge AND expertise ALSO with the below mentioned as well as to a broad range of visitors from around the globe!

Practical Tip: LEDs are transparent, so the Cathode (Minus) looks always a bit larger as the Anode (Plus).

When working with electronics WE need to learn a bit theory and mathematics, BUT DON’T worry, it is very easy! First of all which is mandatory, is the “OHM’s Law“. YOU DON’T need to calculate! 😉 There is an online calculator who will do the job for YOU! Click the image below please to access the online calculator and play a bit around with it to get used to it, have fun.
