Deek Robot Xbee Shield and RS 486 interface

Introduction

Our IO expansion board is evolving, this latest V5 IO expansion shield is now supporting Xbee. It combines our popular Xbee shield with IO expansion shield(V4). It even supports SD card which provides the ultimate functional expansion for Arduino so far.  As its predecessor, it supports RS485, APC220, Bluetooth communication, servo control.

RS485

It uses an SP485CN chip to handle comms.
The screw terminals (assuming that the three jumpers are set to '485') marked 'A' and 'B' go directly to the IC 'A' and 'B' pins (6 & 7 respectively).
The screw terminal marked VCC goes to the IC VCC pin (8), and also to the board's +5V line (i.e. the Arduino's +5V rail).
The screw terminal marked GND goes to the IC GND pin (5), and also to the board's GND line (i.e. the Arduino's 0V rail).
The chip's DI (Data Input?) pin (4) is connected to the Arduino's Digital Pin 1 (TX).
The chip's RO (Data Output?) pin (1) is connected to the Arduino's Digital Pin 0 (RX), with a resistor pull-up to the +5V rail.
The chip's DE (output enable) pin (3) is connected (via a resistor) to the Arduino's Digital Pin 2 - this is active high.
This DE pin is also connected to the chip's RE bar (receiver enable) pin (2) and therefore controlled by the Arduino's Digital pin 2 too - this is active low.
Arduino Digital Pin 2 = Rx/Tx 'Enable'; High to Transmit, Low to Receive
So, to transmit data from Arduino Digital Pin 1 you need to take Digital pin 2 high, and to receive data to Arduino Digital Pin 0 you need to take Arduino Digital pin 2 low.

Sample Code

RS485 Transmit Data

int EN = 2; //RS485 has a enable/disable pin to transmit or receive data. Arduino Digital Pin 2 = Rx/Tx 'Enable'; High to Transmit, Low to Receive

void setup() 
{
  pinMode(EN, OUTPUT);
  Serial.begin(19200);
} 

void loop()
{
// send data 
  digitalWrite(EN, HIGH);//Enable data transmit
  Serial.print('A');
  delay(1000);
}

RS485 Receiving Data

int ledPin = 13;
int EN = 2;
int val;

void setup() 
{
  pinMode(ledPin, OUTPUT);
  pinMode(EN, OUTPUT);
  Serial.begin(19200);
}

void loop()
{
  // receive data
 digitalWrite(EN, LOW);//Enable Receiving Data
 val = Serial.read();
  if (-1 != val) {
    if ('A' == val) {
      digitalWrite(ledPin, HIGH);
      delay(500);
      digitalWrite(ledPin, LOW);
      delay(500);
    }
 }
}

Bell and Howell GSAP Camera and Boresight

This is a  Gun Sight Aiming Point Camera.  G.S.A.P.  16mm film, Bell&Howell.  standard 16mm 50' cartridge compatable also with Filmo cartridge cameras.

 I have this camera currently, which is a naval camera.  Still trying to find out which aircraft this would have been used on.  F8F?

Also there is an image erection device which I don't have.

I will have to find out how to trip the shutter w/o the power, as I assume that might be the way the boresight was used on the airframe. ]

See here for a titling device.  This allows the pilot to put a labeled leader on the film

Bell and Howell Titler

This camera came with a Kodak Kodachrome loaded cartridge, which of course is probably a brick as noone has any chemistry for Kodachrome, and certainly it would be horribly expensive to get 50' developed due to the amount of chemistry required for movie film.

Luckly there is no lost color footage from WW2, most likely because the capacity indicator is at 50' showing no usage.

Pyrolytic Graphite Monochromator

http://www.2spi.com/catalog/new/hopgsub.php

Use as graphite monochromators:

The HOPG offered by SPI Supplies, especially the SPI-1 and ZYA grades, are reported to diffract x-rays and neutrons with a higher efficiency that any other material. For x-rays the intensities are increased up to five times greater than what would be possible with the lithium fluoride crystal it would replace. A singly bent focusing monochromator using these highest quality grades of HOPG, i.e. those with the smallest mosaic spread, result in intensities three times that of LiF at the same resolution.

For X-ray and neutron analysis. Size: 25mm x 25mm x 2mm. Grade ZYA Flat. 

Bausch & Lomb Deuterium Source power supply (acts 2 and 3)

Another deuterium source showed up on epay and the seller took my offer.  I had three power supplies and one head, now I have 3 heads!  When it rains it pours.

These are pretty rare, and this is one of the best units for UV monochromatic work that is available.  other deuterium sources are scrounged from UV-VIS devices or AA spectrophotometers which have been broken up.

Of course you can buy one new and pay lots more than this but the newer units are not as nifty as this one.

Lamp with vent stack removed

exit hole, with filter clips

power supply connector

This unit is pristine

Lapel pin collection

2 Microdata 5 year pins, a GTE pin with 2 blue stones, Rotary pin, some sort of Lodge pin, plus a jade bead pin.

There are a lot of these in triplicate, shot with camera HDR mode, which brackets the exposures.

Fastair lenses. Elgeet and Wollensak.

2 inch, 35mm, 2 x 13mm (1/2 inch)

in 16mm format 1inch, 25mm is "normal" lens.  This 50mm is F2, which is pretty fast for 16mm telephoto.

both 13mm lenses are very fast, f1.5
