    Dimensions not showing in Part

    Sketch dimensions in V15, I place in Part, do not show up unless I move the cursor over them. The lines and arrow heads show in black, with a gap where the number should be. I.e. |<--- Blank --->| Have I switched something off inadvertently? Tony

    Turning off computer or exiting from program through VB5

    Thank you for that John, as the program saves a data text file every 10 mins, shutting it down or rebooting would not be a problem. I'll write a test program and tryout all your suggestions. Tony

    Turning off computer or exiting from program through VB5

    I have a computer running Win98 monitoring a testing machine. The readings are via the parallel port using a Pico adaptor and VB5. The 3.3v from the parallel port via a transistor and 2 relays (one is latching), switch the machine motor. The idea is, that on completion of the test or if the...

    Television Remote Control

    I am in the process of designing a machine, one of the functions of which, is to switch of the television by emitting an "off" remote control code. I realise that each brand of television has a different code. Is there a universal "off" code? Where can I obtain a list of "off" codes? Tony R

The apparatus is inside a laboratory building...

    Side Channel Air Blowers

    I have an application requiring 120 l/m (4.25 ft3/min) of air at 10 kpa (1.5 psi) and I need to power it from 12v DC, 10A max. The project is in prototype stage and I will probably make a unit to test the idea. Whilst I know how side channel blowers work, I have no idea how to calculate the...
