When you logon to your computer, the error Can not find script file CWINDOWSrun. Windows Script Host in the title is shown, in a blank screen with black. Can you be more specific about what youre doing and what applications youre using I just downloaded the PDF to verify, and it works fine for me. I got this same problem because of a virus fix. I added a couple default programs in the set association panel but obviously no cigar. I was happy to find this fix. Aptana Studio 3 The professional, open source development tool for the open web.

Steps with PicturesThe interface board takes eight control lines in, from an Arduino or a PC parallel port, and can make the wheelchair think the joystick is being moved. It does this using transistors, some diodes and a bunch of resistors. All of these parts can be found at mouser. Since the transistors 2. N7. 00. 0 are FETs, they draw no current although their default mode resistors take a milliamp or so so they can be driven from any digital control signal. The diodes we used are 1. N4. 14. 8. A datasheet for the 2. N7. 00. 0 transistor can be found here http www. N2. N7. 00. 0. pdf. Can T Find Recently Downloaded File' title='Can T Find Recently Downloaded File' />The circuit contains eight transistors. Two of them pull the forwardbackward wire toward ground through a resistor each. One has a larger resistor and the other a smaller one. When both transistors are turned on, both resistors are pulling toward ground, representing maximum speed in that direction. Another two transistors are used the same way for the leftright wire. The other four transistors are connected between ground and a resistor to the 1. These transistors are normally on, and their drain terminal is connected through a diode to the forwardbackward or leftright wire. When these transistors are turned off, the resistor is no longer pulled toward ground and the joystick wire gets pulled toward the 1. This is an easy way to let an eight bit TTL 0 5. V diigtal controller like the PC parallel port or 8 pins of an Arduino control the 1. In actual practice as you can see by looking at the schematic and the actual circuit the resistor values have to be chosen to achieve values which will not cause the wheelchair brain to think there is a malfunction in the joystick. K and 6. 8. K resistors are to pull the transistors inputs to their default state, so the joystick works normally when nothing is plugged into the interface boards input side. To determine resistor values, start with a variable resistor a 1. K ohm is a good start and connect a wire to its center and left terminal. With the wheelchair safely elevated to prevent movement or with the operator safely in the seat with room to drive around connect the variable resistor while taking notes. Start by connecting to the leftright wire and ground and with your variable resistor turned all the way to the right. K ohms.   A picture of a variable resistor is shown below. When the leftright function is activated on a wheelchair, it rotates about its center like a tank. Make sure your feet are safely in the stirrups or you could get hurt If the wheelchair does nothing, turn the knob left until the slowest speed desired happens. Disconnect the resistor, measure it with an ohm meter, and write everything down how it was connected and what the chair did. Do it again and find the lowest resistance and the highest speed desired and write that down. For this direction, you will need a resistor for each of the two transistors associated one will be the value of the first test slowest movement and the other will be get ready the inverse of the inverse of the value of the second test minus the inverse of the value of the first test. This way, when both transistors are activated, the wheelchair sees the resistance of the second test. You can always just round up values if you dont have the exact right number. These resistors and the next two will go on the lower transistors in the schematic, to pull the joystick wire toward ground when those transistors are activated. This test must be repeated with the forward backward wire you might go backwards at high speed. Take notes. After those two resistors are figured out, you will need to try the same tests but this time, connecting your variable resistor through a diode to the Red wire, which has 1. Dont let this Red wire get shorted to ground, even for a second you might FRY your electronics. The results of these tests will be the resistor values chosen for the upper transistors, which pull toward the red wire as you can see in the schematic. Bombay Sisters Devotional Songs on this page. Once you have determined the resistor values you want to use, or even before that, you can build the interface board. We used perfboard and assembled it according to the same physical arrangement shown in the schematic image seen below, except that we used 8 pin machine sockets which work well for shoving resistors into, so that changes can be made to the speed of movement of the machine. You could also just use a bunch of 1. K ohm variable resistors. Perfboard on Wiki. Pedia http en. Perfboard. The Gate terminal of each transistor goes to one of the eight control wires of the input cable. We used a DB2. 5 Male connector since we were originally using a PC parallel port. The control wires are connected to pins 2 through 9, and ground to pins 1. We then had to make an adaptor to connect this to the Arduino when it replaced the parallel port in our setup. You can skip the whole DB2. Arduino to the transistors on the interface board as long as you wire it up the right way, which is easier without the extra step anyway.
