I've got a REMA 74/E-06010 AC motor that I want to use to test my alternator when I have rebuilt it. Only problem is, it turns the wrong way to make mounting easy, so I'd like to reverse it if possible.
The markings are as follows:
Connector block:
There are six wires coming from the...
I have a device with an NEC uPD70320 V25 microcontroller.
I have a copy of the EPROM for this device, and I know it contains a data table. The data table is out of date, so I'd like to have a shot at updating it. To do this I really need a disassembly.
Does anyone know of a V25 disassembler...
I make it my standard practice to always use binary for TRIS and other registers that have a bit format. Saves no end of confusion, and I'm easily confused!
Thank you. I've had a play and come to much the same conclusion, except I made them a bit longer and spaced them at 2.54mm as I work in 1.27mm quarter grid. Having done this, I think I'm going to modify a lot more of the solder lands in my software package (DesignSpark), until now I've tended to...
I have bought several OPTEK OPIA412ATU optocouplers, from the OPIA400 range. The datasheet doesn't give much in the way of soldering footprints, just that this type is "Package Style A", which may be an internal OPTEK name.
The dimensions are given thus:
Where can I find the soldering...
A friend has a boat on which the rev counter reads very high since fitting a new alternator, it uses a feed from one of the coils to generate the display value.
I'm thinking of a design to measure the frequency of the incoming sine wave, then generate a square wave of a lower frequency to...
OK, I've come up with this circuit. I'm not very good with discrete components, so I would be grateful for any advice.
To recap, the SeaTalk bus is normally held at 12V (through about 15k), the bus is pulled low when sending the data stream, so needs to be inverted both ways. I want to...
Thank you for explaining what is going on, it helped a great deal. The problem with keeping the circuit as-is is that it has more components than my main circuit; this was meant to be an add-on function!
Your point about an existing IC has got me thinking: perhaps I could use a CAN bus driver...
