That project

[hotpoint95622]

An up date of that project, if any one is interested.

Well the program is written (lots of coffee and lots of bad swearing) and blown onto the chip (PIC 16F872) using the PC, would not work to start with as I don’t know how to program any thing, it’s amazing that it works, hours of reading books and copying examples and trying again and again.

Most of the timings I have based on the Hotpoint 95622, spent hours watching it and counting the second between wash actions, main wash 12sec tumble with 6sec pause and 6sec tumble with 12sec pause for heating, spin times ect.

I have made a circuit board to hold chip and its power supply and used a quarts crystal as a clock, same thing as in your battery watch or wall clock, and some connecters to the outside world.

I have had to make a circuit board for the chip to control relays, chip works on 5 VDC and the relays work at 12 VDC so have to us transistors to act as switches. Relay control 230 VAC components ( heater, motor, valves and pump )

I’m working on the display and key pads at the moment, which will show program and its progress with some LED’s and some neon lamps for the power, lock and heater. I have also designed a control panel to make with Perspex plastic.

designed of control panel. single switch operation with only the programs I use!!!!!!!!!

More to come soon when the display is set onto circuit board.

really intrigued to see how the project pans out.
i take it you will be mounting it all in/on the carcass of a washing machine - any plans as to what type?

keep us posted.

cheers

So you are building your dream washer? Mr. Unimatic1140, site owner & founder also built one but it didn't have its own control panel. A computer ran it.

Wow

Hello Lee.
Eddie here. That's an amazing project your working on.You've got quite a talent there. Good Luck and I hope everything works out fine.

Hotpoint 95622

Yes, paul

I’m looking for a host machine for the project, I would like to use a Hotpoint, maybe a 95 or the range after ( I can here the gasps, especially when I’m going to strip all the wiring out of it, like the Texas chain saw massacre ) or a tricity bendix like the aw1053 that we use everyday. But I don’t think it would be appreciated if I pull that apart, it relay doesn’t mater but it must have a separate speed module and motor that are in good order (so that basically means it must have had a mechanical trimmer ) as I don’t yet have the knowledge to built the speed control that is required. I have used a zanussi studio compact machine but it was to small for the purpose, I have kept all the components including the motor and speed module, but it works at a different ratio to a full size machine, but it did prove that my program will work and that I got the valves and pump working at the right time and controlled the motor.

Incredible!!

Good!! We're all thinking that the dream's machine you could build it up by yourself.
I'm trying to do the same but basing on the Ignis Superautomatica which is shown in the collection. The control panel will have the same 8 pushbuttons for 8 cycles but they'll be different and more up-to-dated of course!!

I thought to use a common PLC casebox instead of an electronic mainboard.

Yes the problem is a carcass but what problem with it if you've already found hot to manage it!? LOL

GoodBye and keep in up-grading!
