Maker Inspiration-WHERE to GET Information to Stay Informed?

Well, you jumped in into the world of makers (OR want to do SO soon…) and you feel comfortable with it? You found out THAT it is important to learn about THAT movement as it brings out creativity and a BETTER understanding in EDUcation WHEN one touches the stuff and it is done by YOURSELF???!!! You learned THAT <===> #LEARNingByDoing <===> is VERY important???!!! THEN, of course you would like to stay informed about WHAT is going on around in the world of THAT movement, ISN’T it???

I would suggest you to read my following blog posts first, please, before I will give you some VERY interesting links to stay Up-To-Date:

SO, NOW you have the necessary information about WHAT it is! Let us look NOW WHERE WE can find inspiration, news, tutorials, etc. for our interests:

This list will GET updated as soon as I have found new resources…

First Steps with the Arduino-UNO R3 | Maker, MakerED, MakerSpaces, Coding | Xmas Star with NeoPixels WS2812B

First Steps with the Arduino-UNO R3 | Maker, MakerED, MakerSpaces, Coding | Xmas Star with NeoPixels WS2812B

.

NeoPixels WS2812B Xmas Star

.


Xmas Star with NeoPixels WS2812B made from cardboard

Xmas Star with cardboard and NeoPixels WS2812BSoon there will be Christmas and decorations are getting put around the house worldwide as it is tradition since ages to do so. That’s also the time for tinkerers, makers to GET some new ideas. Well, I thought on a project which everybody could do without having a 3D-Printer NOR a Laser cutter at home and not having access to them on other places. SO, I tried out to create a Xmas-Star from cardboard using an Arduino UNO and Neopixels…

I recently bought 1 Meter of Neopixels WS2812B with 60 LEDs and tried it out while wife was looking at it and she told me if that wouldn’t be an idea for making a Christmas-Decoration, e.g. a star. I took that challenge and a day later it was working, LOL 😉 I used a 3,5 mm thick cardboard from a red wine box which was stable enough to create the project.

 

The measures are 160 mm x 160 mm and there are 8 segments with an angle of 45° (8 x 45 = 360°). This is quiet easy to draw on cardboard… Once the lines drawn, up from the middle line draw a 1 cm to the left and to the right so that it makes a 2 cm width of each segment. On the middle cut out a square hole from 1,6 cm. That is the perfect outfit for the Christmas-Star. Cut it out with a sharp cutter and paint it with the color of your choice, I used green… NOW take the 1 meter long ribbon and cut off 8 x 4 LEDs. THEN take off the protection paper from the Neopixels WS2812B ribbon and glue them on the cardboard, see PIC please.

 

Find below, please, a drawing with the dimensions and where to cut out:

Dimensions of the Xmas Star

 

You may have a look on this Tutorial to know a bit more about the handling of Neopixel LEDS, please:

The project itself by cabling is actually VERY easy, ONLY 3 wires, the MOST work is on the mechanical part by cutting the cardboard, painting, soldering the Neopixels WS2812B strip and to put everything into a box with the necessary parts, while drilling, etc. WE will see this in detail by following PICS… But first let us solder and interconnecting the 8 x 4 Neopixels LEDs strips, you need to follow the arrows on the strips to connect each of the 8 x 4 LED strips, thus meaning: see PICs please:

Follow the arrows

.

Please have a look on how this will look in our project; we use color flat cable to make the connections.

.

The flat cable will get fixed with hot-glue on the cardboard.

.

Once the 8 x 4 LED strips are interconnected, you can connect the other 28 LEDs to the point marked with “START” and connect them to the ARDUINO UNO board through a screw terminal to make the first tests. Please check the tutorial below with the code for the How-To:

IF everything is working, hopefully, we can go for the integration of the components into a housing. TIP: prepare the ARDUINO UNO (NANO) already with the code uploaded and test after each 4 LED strips connected to make sure it will work!! it’s BETTER to invest time for NOT later having trouble and NOT knowing from where the fault comes 😉

Xmas and Holiday Gifts Which Make Sense For LEARNing

Xmas and Holiday Gifts Which Make Sense For LEARNing

.

Maker-Coding

.


WHAT gifts to buy for the kids for Xmas and Holidays?

Every year the same question, isn’t it!? WHY not thinking about to buy gifts from where and with that the kids will learn? It might be good to have a look on WHAT are the skills required for the future from youth, students, learners and upon that making your choice! Actually (2017) the trends are in the maker scene and coding scene! Engineers, coding people and ICT specialists are needed, the workforce, industry is searching!!

What is the maker scene?

I invite you to read my bog post about it below, please:

Variable Power Supply-work in progressIn the Makerspaces as well as in Maker-EDUcation the creativity and PracTICE are getting fostered to be prepared for what the workforce and the industry are needing! The kids, students, learners are Learning-By-Doing and that is with fun involved also! They are not only tinkering around but they get coached in a “NO Hierarchy” space; in Luxembourg. SO, they can communicate with each other to solve problems and as well later also doing the same through the Social-Media and forums. They learn also by that way to build teams and are able for team-work later once out of school.

.

Team-Work is one of the essential skills which students, learners need to have for the future! Read also my blog post below, please, which explains WHAT the skills for the future are:

Learn more by reading my blog posts from Makerspaces in Luxembourg:

In the above blog posts you will find information what is happening and you can contact the responsible persons for more information; let your kids go there and have fun by LEARNing-By-Doing! 😉

What is the coding scene?

Coding is the 21st Century skill. Coding enhances creativity, teaches young people to cooperate, to work together across physical and geographical boundaries and to communicate in a universal languageTechnology is part of our life, and coding brings it closer to you!

LEARNing By Doing-A MUST in Modern EDUcation for BEST Results

Let us START with a Chinese proverb from Confucius <===> I hear and I forget. I see and I remember. I do and I understand. Already more than 1500 years ago, this wise man was talking about “Learning By Doing“. Please check below:

.

Confucius-Learning By Doing-BrainyQuote

Click image please to access more quotes from Confucius.

.

More about Confucius:

Research shows that hands-on learning is an effective way to teach students science. A 2009 study found that eighth-grade students who were involved in hands-on science projects demonstrated a deeper understanding of concepts than students who were taught with traditional methods such as textbook readings, lectures, and tests (Riskowski et al., 2009).

Sustainability: EVERY kid (nearly) has a smartphone, right!? Smartphones can take ALSO photos (NOT ONLY selfies… use them on intelligent way), so WHY NOT using them to teach the kids about the nature?  To make them curious about WHAT is around them when they walk outside the house! Make it like an adventure, show them, guide them, show them ALSO WHERE to find plants, flowers by uploading an image on Google to find out WHAT it is; this is possible, click below please:

SHOW them How-To use Photo-Editors to enhance taken photos and to bring in text into the photos (this e.g. the name of the plants, photos, animals, insects…).

Maker-First steps in electronics-The moving, rotating and lighting Mini-Brush

Maker-First steps in electronics-The moving, rotating and lighting Mini-Brush

The moving, rotating and lighting Mini-Brush

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

.

led-symbols

.

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

.

led-symbols-anode-and-cathode.

.

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.

..

ohms-law-calculator

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]

Learn more:

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 😉

Here below the schematics where YOU will see how the components are represented; YOU will remark that we have three (3) times a parallel circuit. Two batteries in parallel, two flashing LEDs in parallel and two vibration motors in parallel.The resistors are NOT shown in the schematic as THEY are NOT connected, they are just used as stabilization of the statue!

.

moving-and-rotating-electronics-statue-schematics-screenshot

.

WHY connecting batteries in parallel!? Check below, please:

To find it out I recommend to make a bit PracTICE:

  1. Try first to use ONLY 1 battery CR2032 and let run the statue.
  2. NOW use two (2) batteries CR2032 and let run the statue.
  3. Use NOW ONLY one (1) battery CR2430 (they are bigger in diameter and on power) and let run the statue.
  4. NOW use two (2) batteries CR2430 and let run the statue.

Both batteries deliver 3 Volts, BUT there is a difference in the possible current they can deliver. The CR2032 delivers 225 mAh and the CR2430 delivers 280 mAh!

Through THIS “Learning-By-Doing” YOU will easily understand it!

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.

Half Square Nut as unbalance

Click image please to enlarge.

.

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.

.

Learn more:

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.

The price is around 35€, but worth to spend that money, comfortable precise working…

 


The Parts List

As mostly usual in my tutorials, WE will create on the beginning ONLY small stuff with some effects and a little bit of theory to give YOU the fun and the sense for electronics. SO, in this project there also ONLY a few components, such as: 9 Volts DC-Motor, Flashing LEDs, 1 resistor, 1 switch, a 9 Volts Battery, a plastic container (actually a Ricotta Cheese plastic container).

The Mini BUG Robot

In last blog post (tutorial) WE were practicing OUR soldering by creating “JOHNNY the ski-man“, a bit “Electronics-Art” using electronics components. In the video below, which I created with the FREEWARE <===> Windows Movie Maker <===> WE see ALSO “The Mini BUG Robot” who gives “JOHNNY” a ride. It is very easy to build that mini robot as there are ONLY six (6) components to solder.

.

.


The schematics

Let us first have a look on the schematics where WE will discover some NEW stuff, a mini motor; in this case it is an “vibration motor” which is used in smartphones. THEY exist as round, rectangular and in disk format, please check <===> Vibration Motor Images <===> in Google searches (images).

.

Maker-First Steps in Electronics-Soldering Learning-Electronics Art

Maker-First Steps in Electronics-Soldering Learning-Electronics Art

. 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) 😉

Please click image to access the article for more information.

.

.

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.

.

.

Where to start? The mechanical part

sawing the stripboard

Click image please to enlarge.

.

.

.

WE will start with the hardest part of the job, the skis. The skis are made of a small part of a stripboard which has to be sawn; we count four (4) holes and saw along the strips there, see pic. The length would be about 5 cm ( +/- 2 inches).

.

.

.

ski detail

.

.

.

Once the two (2) pieces of the stripboard sawn they must get rasped to look smooth. See pic please.

.

.

.

.

Skis detail

Click image please to enlarge.

.

.

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.

.

The soldering

Soldering order details

Click image please to enlarge.

.

.

.

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.

.

Hint: For THOSE who can’t wait for NEXT tutorial, have a look on my proposed links in this tutorial and YOU will find more 😉
