My dip maker shuts off. This is very frustrating, since no human should attempt the consumption of six cups of coffee within thirty minutes.
I’d like to get rid of this timer, but I can’t see anything obvious on the board. Is it most likely to be in that little processor at the top left of the coated side?
You’re supposed to transfer the coffee to a thermos when 30 minutes is up. The coffee “burns” after that.
This thread is about removing unwanted features from kitchen appliances, not a debate over how the guy should enjoy his coffee according to you.
The smarter move is to simply buy a coffee carafe.
Or get a coffeemaker that brews directly into a carafe. Black and Decker usually goes for $75, and the coffee stays at a drinkable temp for 3+hrs
I would rather drink one well made cup of drip coffee followed by the piss that coffee produced, than coffee that’s been sat on a hot plate for 30+ minutes.
you and me are different, and that’s okay
I appreciate good coffee. I don’t care enough to have it on a work day when I just want something hot enough that I don’t drink it all immediately and with some caffeine in it because I have a severe caffeine addiction that’s developed over years and years that I haven’t addressed yet
I will rebrew coffee grounds in my single cup maker because I am that lazy and do not give a fuck about it being shit weak tea that it produces on the third rebrew. my recent upgrade was to using a regular drip machine again and I chose to lower the bean amount to near piss water levels to compensate for the fact that I was previously getting less and less caffeine with each brew whereas now it’s just equalized across all cups
there are a couple reasons I drink coffee, and how I drink it is reflected clearly by them:
I make better coffee backcountry camping than I do at home
yw for the horror story
Wait until you find out there’s a lot of people that like burnt cheap coffee.
They’re over represented in the “previous military service” and “blue collar shift worker” demographics.
This is probably a bad idea, because the timer relay circuit probably has some additional safety features in it such as temperature limits, along with the device never being designed to run indefinitely.
If I had to guess, the heating element is controlled by the relay (big black cube). I would either bypass the output or bypass the input signal. The relay pinout can be easily found online on sites like this.
It almost certainly is designed to run indefinitely, this exact same coffee maker has been in production since the nineties or so. the only addition is the timer circuit, which is very clearly a much later addition, as the supporting structure is markedly different tk the rest of the device.
Anyway, a 240v switch is in order, I think. Fortunately we still have Farnell here in the UK, I shouldn’t like to pay international shipping fees for a single switch from china.
Bridging brown and red or whatever colours not blue and white are will bypass the board entirely.
If that is the only pcb in the device op should be able to just put any (mains capable!) switch there to just toggle the entire device on/off
It certainly isn’t on the second PCB. That’s the power supply and I’d definitely keep my hands off that. YOur best chance is to look for an IC with “555” in its’ type number. That’s the most commonly used timer chip. Search the net for a data sheet for the specific type and find the right pin to ground. It should be the one to start the timer; depending on the way the timeout is implemented it might also be the “set” pin.
I suspect that the IC is the eight-pin thing I saw in the top left. It appears to be the only one there tbh, but it has a coating over it to hide the labeling for some inane reason. Bah.
I would be furious if the hot plate turned off after 30 minutes lol I thought I had it bad with my coffee pot at work turning off after 2 hours.
Try and find the wiring that connects to the hot plate itself and then work backwards from there
This is what I would do if I’m dedicated enough to this laziness and didn’t care about starting a fire in my house:

Leaving coffee on the burner makes it taste worse than reheating it from cold in the microwave. That and a fire hazard is why coffee makers cut off the hot plate so quickly compared to older models.
northernscrub@lemmy.world 6 days ago
The fire hazard is no greater for removing the timer, there’s a bimetallic strip in there that will detach from circuit if the thing gets over 90ish degrees. It’ll just keep cycling like that. Microwaving coffee tastes, in my opinion, worse.

If it’s functioning correctly that is true, but eventually that part can break, and if each use is 4 times longer than the current setting it increases the chance it could break. Even if that mechanical component is devilishly simple. Both reheating and keeping it warm breaks down the sweet and acidic elements leaving the bitter taste. The difference is reheating a single cup will do this less (especially if you use a lower powered setting on your microwave) vs continuing to do this to the whole pot as you come back to it over and over. Your preference might just be your own desire for that acidic taste or caramelizing of other elements added to the brew for flavor. My suggestion would be to just make less more often, or get a hot plate and move the pot over to that instead.

I bought a drip coffee maker… there is zero timer, it will never shit off unless I manually toggle it off or unplug it. this is a 6 month old coffee maker.
bought SPECIFICALLY because it had ZERO ‘features’.
its_kim_love@lemmy.blahaj.zone 6 days ago
Okay. Nothing about my comment was supposed to imply that it’s not possible. My comment was reminding OP that there is probably a reason why his doesn’t do that, and that reason is probably informed by the quality of the parts used to make his coffee brewer in particular. I’m not saying it’s impossible to make them that way. The manufacturer chose not to do it, and that alone should make you wonder what they changed because of that decision.

My Ninja has adjustable heat hold up to 3 hours.
its_kim_love@lemmy.blahaj.zone 6 days ago
And they engineered that feature and tested that feature and supported those parts to make sure they can do that for the life of the machine. I’d bet your Ninja also cost more than OPs brewer.

I’m a big boy. I don’t need my kitchen utensils making decisions for me.
