IchigoJam Choco Vendor with a card reader

Just verify the card insertion.
Enables one pc of  choco vending out by hitting the red button.

IchigoJam Choco Vendor + Card Reader

 

Gave up to make a coin accepter then used a card reader instead.

 

Just sense the card insertion and it enables the button switch.

 

コインアクセプタをつくるのは、たいへんなので、カード挿入式にした。

といっても、挿入確認だけ。

 

カードを入れると、一回だけチロルチョコボタンが押せる。

 

・タミヤのギヤー　は、最低速にしたので、トルクが強い。チロルが詰まると固まる。

モーターはOFFにしても惰性で動く。

Made this

Proto 0.1
Tested:  Circular motion to liner sliding  motion to push the choco out.
              SW the Tamiya Motor by a tr with OUTPUT of IchigoJam.
              Controlled by the IchigoJam(LPC1114)  and BASIC programming

Wait the start  tact switch ON
Start motor
Timer(TICK) reset for "timeout"
Wait the limit switch ON
Stop the motor after WAIT for the  point
Monitor the HALT swith to avoid the overload bcause of  jamming choco

IoT and Vacuum Technology

IoT + : Something

Think about something unique with IoT

Need something unique to create new idea/innovation.
IT can't be useful without things.

Not many hacker people image the vacuum technology as a seed of new idea

Talking about 10^-6 pa enclosure from 0.5"sq up to 5"x7" glass box

Sensing devices

Trial stage 1

Advantages? Benefits?

No air influence: Ultra high sensivity G sensor,

A micro mirror driven by electric field: the response of movement could be improved significantly.

The reliability also be improved due to less interference of  gas inside ,

Traffic Signal Programming Kit for Kids

 

Traffic Signal Light Programming Kit for Kids

Kid's computer "Ichigojam" BASIC Programming 

Purpose

Open the first step for age 9-12 kids to learn programming.

Encourage kids to learn fundamental programming knowledge with lighting LEDs as a traffic light.

Use fundamental commands to control LEDs.

 

 

9yr old kids understood the following commands and program flow;

OUT

WAIT

GOTO

--------------------

Wiring

IchigoJam board and LEDs

OUT1   LED (Green) via a resister to set the current.

OUT2  LED (Yellow) via a resister to set the current.

OUT3  LED (Red) via resister to set the current.

Each resister should be adjusted to set the LED current.

Normally 5 to 10mAea.

Programming Commands

Some hints

Stage 1:

Kids understand how OUT commands work

 

10 OUT1,1           'Light Green ON

20 WAIT 600       'wait approx 10sec.

30 OUT1,0           'Light Green OFF

Stage 2 :

Kids understand how INPUT command works

Change the signal light duration / timing

Input the each LED time from keyboard

 

10 INPUT"GREEN",G

20 INPUT"YELLOW",Y

30 INPUT"RED",R

 

WAIT G*60 

Stage 3

Kids can use to simpify the program flow

FOR NEXT

IF THEN ELSE

Interesting VFD Hacking Video EEVblog #717

Found an interesting Youtube Video.

It looks 1980's old type VFD  moduled by Bubcock/US.

And it 's driven by Arduino 30years after its production date!

He explains how it works.

EEVblog #717 - How To Hack Vacuum Fluorescent Displays

Easy use :VFD Module 2 x 20 Character Display UART Interface

 

Got a VFD Module

CU20027-Y1A    Easy way to use by UART

  

1. Use a VFD

The best possible readability needed  for the application.

The reliability is another important factor considering factory use.

I used an ASCII VFD Module. It has 5x8 dot font and 2x20 character position.

       Simple interface and command to control preferred

 

2. Easy  to display text messages

I wanted the minium design time for hard and soft works  I used minimum commands.

 

This module has so many functions but I need only a simple text indication.

I used only simple ASCII commands.

I tried not to use  the code library and other support softwares.

 

1) Power supply

I used a 5V 0.5A power supply . 200-300mA current flow observed in operation.

Wiring : Two wires, 5V to VCC, 0V to GND(common)

 

2) Data

UART (Asynhronous Serial)  38.4Kbps (Default) or 19.2Kbps (Jumper 0 short)

I ignored "BUSY" signal to reduce the wires.

Wiring : Only two wires, SIN and GND(common) are used to nterface to the host.

 



3. How it looks

It's so bright. A plastic color filter is recommended to get a better contrast.

Green,Blue,Gray colors can be used. The photos are my favorite colors.

UCU20027-Y1A VFD Module  with a "Neutral" acrylic panel

 4. Programming

1) ASCII control code

Just send a Home Position "0Bh" at the initial setting.

It clears the screen and sets the cursor position in the left top.

I don't use the cursor indication so I sent "14h".

 

2) Character code and font

Straightforwardly,send ASCII text code to indicate the text you want.

 

3) Other commands

There are so many useful functions but maybe I use some unique commands;

"Font magnification" :1F 28 67 40 xy

Enlarge the font 2x or 4x .

 

"Individual Character Brightness Level Setting" : 1F 28 67 50 d1 d2 d3

Brightness of each chaaracter can be set by 8 levels.
