<small>Bank ATM.<br>
|
||||
|
||||
The goal of this project was to create a banking system, including an ATM
|
||||
client. It was created for one of the courses (project 3) at Hogeschool
|
||||
Rotterdam and was written in C++14 and Qt4.
|
||||
|
||||
The
|
||||
[slides](https://docs.google.com/presentation/d/1W0L4e7r0Vqp5Qp3RaNcMhqrt1gkLSrU4T6heOZz_IqQ){target="_blank"}
|
||||
for the presentation that I gave at Hogeschool Rotterdam.
|
||||
|
||||
## Product demo

||||

||||

|
||||
## Overzicht systeem
|
||||
|
||||
De applicatie bestaat uit 3 threads, welke allemaal een unieke functie hebben.
|
||||
De main thread bevat de GUI. De database thread voert alle queries uit en slaat
|
||||
deze data op. En als laatst de serial thread, deze thread bevat een listener die
|
||||
alle seriële data ontvangt. Afhankelijk van wat de serial thread aan user input
|
||||
ontvangt zal de SerialCommand class "commando's" uitvoeren die de GUI en
|
||||
database thread gebruiken.

||||

Ten alle tijden kan de sessie worden afgebroken door de pas uit de pinautomaat
|
||||
te verwijderen, de interface wordt daarna naar de inlogpagina doorgestuurd. Alle
|
||||
velden waar de gebruiker gegevens kan invoeren, hebben de mogelijkheid voor het
|
||||
weergeven van foutmeldingen.

The goal of this project was to create a working miniature elevator. Each member
|
||||
of the team made his own level, which we would stack on top of each other in the
|
||||
end. The engine room was a combined effort of the team and it would talk to all
|
||||
the levels via I2C. This was my first project at Hogeschool Rotterdam.

De sensoren worden aangestuurt met een Arduino Uno.

De uiteindelijke aansluiting ziet er als volgt uit.

This page describes my version of a smart socket for home automation.
|
||||
The device can be toggled via the button on the enclosure or a wireless signal.
|
||||
|
||||
## Build
|
||||
|
||||
Pictured below is a scetch of the concept of the project.<br>
|
||||
As well as an electrical circuit.
|
||||
|
||||
|
||||
|
||||
The MDF enclosure is cut out with a laser cutter. The base of the design is
|
||||
generated via
|
||||
[boxes.py](https://www.festi.info/boxes.py/ClosedBox).
|
||||
Holes have been added to the base so that the cable,
|
||||
socket, LED and button can be mounted.
|
||||
|
||||
|
||||
|
||||
The button is printed with a 3D printer, the bottom part of the button is
|
||||
extended by 2mm on each side (4mm in total), so that it stays in place.
|
||||
|
||||
|
||||
|
||||
This is the final electrical circuit that was used, which is made in Fritzing.
|
||||
All hardware components (minus the power supply) are incorporated in this
|
||||
circuit. A red LED is used as an example appliance that can be toggled.
|
||||
|
||||
|
||||
|
||||
Pictured below is a model of the design in Tinkercad, the button will be printed
|
||||
in 3D and the housing will be cut out with the laser cutter. The black cylinder
|
||||
represents the power cable.

Unfortunately, the original design was a little fragile at the round part that
|
||||
would slide into the housing and it would snap off. I tweaked the design by
|
||||
moving the USB port up by 1mm and reinforcing it by attaching it on the sides,
|
||||
as there was space to do so. The 3D bezel design was taken from here:
|
||||
[thingiverse.com/thing:3066354](https://thingiverse.com/thing:3066354).<br>
|
||||
The new edited design:
|
||||
[thingiverse.com/thing:5664077](https://thingiverse.com/thing:5664077).<br>
|
||||
This is the USB-C port I used:
|
||||
[aliexpress.com/item/1005002328403673.html](https://aliexpress.com/item/1005002328403673.html)
|
||||
|
||||
## Build
|
||||
|
||||
Unmodified, the original cable hole is a little too narrow to fit a Type-C port.
|
||||
|
||||
|
||||
|
||||
I used the nail file to slightly widen the hole, this is what it looks like afterwards.
|
||||
|
||||
|
||||
|
||||
Initially, my plan was to replace the original connector with a male pin header
|
||||
and dupont connectors, but my soldering iron couldn't get hot enough to melt the
|
||||
solder of the thick pins. So instead, I repurposed the original wires.
|
||||
|
||||
|
||||
|
||||
I used a third hand to help keep the port in place while soldering.
|
||||
|
||||
|
||||
|
||||
Finished soldering.
|
||||
|
||||
|
||||
|
||||
Test fitting everything together.
