Half Square Nut as unbalance

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.

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“.

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:

.

led-series-resistor-calculator

.

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.

Useful online help:

 


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.

.

Concerning the hot-glue pistol which you need as well, I recommend the one from “STEINEL” as it is a Cordless all-purpose glue applicator. Neat, practical, accurate. Cordless hot-melt glue pen neo1 for all gluing jobs around the home, particularly lightweight and practical, cordless gluing with rechargeable Li-Ion battery, ready for gluing in 15 sec.

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).

Maker-First Steps in Electronics-Soldering Learning-The Mini BUG Robot

The Mini BUG Robot

.


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).

.

minibug-robot-schematics-screenshot

.

As you can see there is NOTHING special; we just put four (4) elements (2 LEDS, a vibration motor and a tantalum capacitor) in parallel. And we have a switch to switch on/off our circuit. As battery we use a “CR2032“.

Very important

In OUR above project we are using two (2) 3 mm red LEDs in parallel. It DOESN’T work when YOU take two different colors, I tried it out 😉 WHY!??? Please check links below:

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.

.

.

Parts List of the components used

Click image to enlarge please.

.

.

The following components are required:

Six (6) resistors of 1/2 Watt, two (2) resistors of 1 Watt, one (1) IC (14 or 16 pins), one (1) LED, two (2) diodes (1N4007), some colored rigid wire for the scarf, 1 mm² rigid copper cable wire and 1 mm silver wire.

.

Tools needed.

The following tools are required:

Vise, rasp, solder iron and solder wire, electronic cutter, electronic flat-nosed pliers, small handsaw and don’t forget the vacuum cleaner for cleaning up the working place later, please 😉

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).

.

.

.

.

.

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

.

.

.

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 😉

The finished project

SO, that’s it folks!  Wishing YOU some fun with this project and hopefully you will get more interested about electronics 😉 Check the video below please to see OUR STAR in action… BTW: The “Mini BUG Robot” present in the video will get proposed ALSO in another tutorial…
