I really appreciate TH-camrs iteratively improving their makes. It shows the makes are actually functional and not just novelty engineering videos. Well done my man
It's a "peristalsis pump". Great video!
Next step, use a power socket with power metering that works with home assistant. You can tell when you power on the washing machine, use that to trigger the 25ml of soap and you can do away with the button all together. Then what I did was hook an alert up in home assistant when the power consumption went from idle $threshold to 0 watts usage (when the machine turns off) so HA alerts my phone "washing is finished".
Yeah definitely not something I’m able to do here but in the future
Why aren't you able to do so?
I should rephrase, I could but it’s not something I wanna do in my current apartment.
@@Mellow_labs ahh okay :) wouöd vs could, my bad ;)
@@Mellow_labsI have installed a Shelly plug on my washing machine (the 16A variant), and based on power consumption, HA sends me a notification "laundry done". Very convenient because our washing machine is three floors up and I can't hear it.
It's just a plug/socket, so you just plug it in and if you ever move, you just unplug it and take it with you.
nice! only the soap dispenser was good already, but the home assistant integration was the cherry on top
Never thought of having a detergent dispenser but it's 100% a great idea. The cycle is very dependent on how much you use (and vice versa) so having it automated would save me quite a bit of cash, especially if it measured the load and used accordingly.
Until the company controls how much it dispenses and requires automatic updates to remain functional.
Using powdered detergent would be better for the machine and cheaper for the end user. You could use a simple screw drive to move precise amount. Modern machine can actually sense how much detergent is required by weighing the load and water used. Buying a scoop in the right dose is pretty easy too though, if your machine does not have the smarts anyways.
@@MiesvanderLippe How is powder better than liquid...?
@@dougle03 it leaves residue which will build up & start to smell.
@@MiesvanderLippe Where does it leave residue? We use liquid and it goes in the drum with the clothes so nowhere for it to hide... Wash liquid should not be put in the drawer...
What I really like about about less smart washing machines is that they will just continue washing once power has been restored. I have a wifi switch hooked to it and at night I start a load and imitatively cut off the power and home assistant has a timer that starts it in the morning so the machine is finished around the time I wake up. Also added an alert that triggers when the machine stops using power and tells me the machine is ready.
I too think it’s pretty cool. I especially like the Home Assistant integration
Could also be integrates to add an item on your shopping cart - or even better, ordering it for itself :D
You are probably using 3 to 5 times too much detergent per load. Try 10ml and see if you can notice any difference. I run my much larger (Canadian LG front loader) on about 7ml per load. About 25 years ago I had an ASKO import (when we couldn't buy front loaders in Canada), they said to test the detergent to see how much to use by just putting in enough so a small amount of suds would form - they had even published a paper with this, but I can't find it on the web now. They had concluded that if there were any significant amount of free suds, this just meant that detergent was not being fully used.
I did enjoy the video, I hadn't considered automating the soap dispenser process. What I want is a way of automating the cycle selection, 95% of the time I run one of three cycles: normal (for mixed colours), hot cotton (whites, towels and bed sheets) or hand wash (for sweaters). I'd just like to have three buttons and hit the one I want to use. Also, I'd like more fine control over the delay start (which is in 1 hour steps on mine), say in 10 or 15 minute steps.
This is awesome! Im definitely gonna put this on my washer
This is very cool. I love seeing solutions to problems I didn't know I had. Keep up the great work!
Thanks, will do!
Great fix! Relaxed drawing on monitors for the win!
Nice video, nice explanation, great upgrade! And now that HA has the shopping list as a to-do list and you can add / remove from to-do lists... you can add the detergent to the shopping list automatically!
HomeAssistant connection was superb, a nice surprice. If you revisit, the tell how accurate the detergent total amount left estimation was :)
I’ll let you know when I finish the 4 1/2 L bottle of detergent 25 mL at a time 😂
@@Mellow_labsIt will last for 180 wash cycles 😅..
If you do once per day... see you in 6 months (-3 weeks)! 😅
thank you for sharing the creative process with us all.
Amazing! Going to copy you because this is on my print list :)
The empty space around the antenna of the D1 mini is not for screws. It the antenna clearance. Putting any metal in this zone will degrade the antenna performance. If you really need, use at least a nylon screw to prevent serious loss.
But hey if it's work for you, that good too :)
This is super cool! Do you think that you could add a smart outlet/plug to the washing machines power and have it automatically add soap when eat detects the washing machine started?
Oh man the possiblities. Beautiful project. Nicely done too!! Thanks.
I have similar almost fully mechanical washer too.
I was planning also doing more then jsut this.
Want to measure temp and have countdown to when its done.
Was planning on Home Assistant integration. And also using power monitor on plug to see what stage it is in the cycle. (got notified when done etc).
What a well executed idea. Definitely understand the ADHD addition at the end, but man is that helpful for forgetful people like myself
Super cool! I love how you improved this make!!
Thank you so much!
And you just got a new sub :) great video! Looking forward to new stuff!
Pretty neat video! For determining how much detergent you have left, you could also get some weight cell, connect it to the D1 Mini and weigh the full and empty detergent container and determine how full it is by weighing it periodically - just keep the bottle on the weight cell all the time. (I am planning to do this with the 5KG CO2 tank for my sodastream.)
I have thought of that but I’ve not had a very good luck Calibrating load cells, so I went with the easier option.
That is a cool project. My washing machine is low tech no place to add detergent like yours. I have to open the lid of the machine and pour it in myself. I did add a smart plug to it that can monitor the power it pulls and tell me when it starts and finishes though. And on the dryer i added a vibration/reed switch that can tell when it is running and when the door is opened and closed. I like your solation better but we do what we can with what we have i guess. 😀
My solution to having to open the drawer (although I didn’t mention it in the video because I didn’t want to take responsibility for it) I drilled a sneaky little hole into the detergent tray and sealed it with hot glue, and it works great. Really cool automations by the way. If I have do version three, I will probably include some of them.
That's sweet! And I even already have a spare peristaltic pump and my washing machine is in a pretty good spot for something like this. Plus I do the laundry and not my wife so the wife approval factor doesn't even play a part.
This is excellent I wish your youtube channel much future success
Im exited for your solid detergent version :)
I have thought about doing this many times. the fact that washing machines dont have this built in is crazy. My guess is it anticipates that people will always pour too much detergent in so Tide gets to sell more product. I didn't think it would be this easy to execute... WELL DONE!
Expensive washing machines already come with this feature, built-in not exactly like this, but they do some smart stuff like optimising the amount of detergent depending on how much laundry is in the machine.
I was thinking in controlling the washing machine in total. Copy the timings of the water income, detergent, rolling drum, pump water out... Controlling it with relays in a esp32. Because electronic pcb gets damage over time with humidity.
This is a start for automation. Detergent is a good step. Thanks a lot
It can be dangerous if your machine doesn't use a hot water inlet and instead use a heater element. If it does, surely a good idea for when the machine dies.
these auto doses are very common on commercial machines. If you connected to the door catch (assuming the door lock has a bimetal strip) this could give you a notification once the washing has finished and the door has unlocked.
Hey, that's a very pretty cool thing!
Great idea, one suggestion, you shouldn't buy detergent when you are running out of it - you should buy it when you are close to running out of it AND it is on "special". ;)
Not something I will use since we use tabs but cool idea and like to see the process. Good job!
great vid mellow!
(the drawing on the monitor at 5:50 gave me anxiety)
Hi, thank you for this video. May I suggest another alternative idea for this project. If the goal is to keep track of how much detergent is left, you can measure by weight and depending on the residue show on the board
I think its pretty cool. Came from tiktok stayed an subscribed👌
Awesome, thank you. That reminds me I still need to make a short form video about this one.
I think you made a pretty cool thing
*Gestures with a drill*
"My tolerances are a bit low"
Absolutely sent me, gotta drop a sub
Great improvements, love the fluid level.
What camera are you using with auto tracking?
First time watching and you got me subscribed
Thanks for the sub! The camera is the insta360 link.
That's pretty nifty, also you've made it to my TH-cam recommended and I'd say I am your target audience so keep on creating, when TH-cam likes your videos you're doing something very right my friend. Good luck (:
well done!
5:42 - He's marking on his monitor screen lol
6:13 Does this while-loop run at full speed all the time, sucking energy and generating heat? I think some short sleep or something were good here.
Yeah I’m pretty sure ESP home has a deep sleep function, I might look into implementing it. It’s not a high priority.
Hey, love the vid what is the screwdriver that you are using during the assembly portion, and how do you like it?
It's a fine screwdriver it's relatively cheap one from ebay I think it was like £45, I'm very often find it not to have enough torque to unscrew things. I'd say it's fine for things like laptops But not PC towers.
Great video! You've got a new subscriber
Welcome aboard!
An interesting observation. I've been brainstorming this myself and one of the driving forces besides being cool is to help reduce detergent consumption. Presently everybody basically just fills the detergent cup to the 'max' line no matter what. I'm pretty sure that's unnecessary most of the time.
The fact that you went so long without realizing that your previous pump wasn't working is a hilarious way to realize that I'm on the right track.
Exactly and you're only supposed to use 25millilitres!
very cool!
That's awesome
One thing is making it smart(er), but another interesting question is if it can be made multi functional - cement mixer, rolling pastry, washing and grating vegetables....
Very funny video ... Periseptic triggers me just like your monitor drawing :-)
After seeing you draw with Sharpies on your screen, I take back my comment about not wanting you to blow up.... ❤
I hope you don’t mean literally 😂💥
I think it's very cool!
I first thought that you would convert the washing machine completely to your diy controller, I would like such a machine for myself, it would be especially cool to be able to fully manually customize your washing algorithm
Yeah, the idea has come up a couple times. I might do it in the future but definitely not anytime soon.
6:26 You know that you can use software pull down resistors too? (from micropython docs: p2 = Pin(2, Pin.IN, Pin.PULL_UP))
Great!
well i misjudged the video , i thought your going to automate the whole machine with home assistant !!
you have the first part ready , you can tap into the electronics of the washing machine easily with relays to trick the machine into thinking you pressed the button
of course automated with home assistant
you can actually tap into the contacts of the switches and send a high or low signals into the wires to trick the machine into thinking you pressed the actual buttons , also you still keep the buttons as they will send the same signals when pressed so you didnt brick it for you partner !!
this could be a series on the channel and i would be interested in it
I would love to, but that is not something I’m able to do because I don’t own the appliances in my apartment.
Maybe you could replace the whole controller with a d1 mini, because that is the most expensive part when it is faulty.
You could have change the opening direction of the door:)
Btw how do you power the system? Battery?
Final thing, when cleaning supplies are left open they usually lose their effectiveness. You can 3d print a proper cap.
It’s on a 12v power supply under the unit, and I drilled a hole in the original cap instead of printing a new one.
this fuckin mad lad drawing with dry erase markers on a MONITOR
I think a scale under the soap would be a bit more accurate, in case of over/under juicing
Very cool project! That time.sleep(1) at the end of the polling loop looks sus though.
Yeah,but it doesn’t really apply anymore because I re-wrote it in ESP home.
i kind of figured that you were doing more than dispensing detergent, but, there it is...
Cool project!
Edit:
@Mellow_Labs - an interesting project would be a small device you can stick on the boiler where it reads off the LED light in case of fault, info, all good etc.
Why don't you just replace the whole electronics from the inside? I had a plan to retrofit my parents old dryer which died and no controller board was available on the market so went ahead and got a new one, kept the old one to build an esp32 controller but unfortunately I had to travel 😢
Cool go on
Were those real markers used on the monitor xD?
nice. where can i buy this? 😂
Think it needs a prime tube button. Also writing on lcd had me worried
grate work someday maybe i will hack mine the same way thanks for the idea
"some of you may have realised that the D1 mini, does not have a mounting hole, some of you may have also realised that I'm holding a drill"
That's exactly when I decided that leaving a like on only one video will not be enought
😂 I’m glad you liked it 😂
Do you have a Link to the Pump you used?
Unfortunately no, I found it in a scrap pile
@@Mellow_labs okay thanks anyway
jeeeeeez, talk nerdy to me.
And to finish it off, use the start button of the washing machine as the trigger for the pump, then it really becomes an automation 😀 (ok, maybe keep the external button as a cancel option)
I would love to, but I can’t just go digging inside the washing machine I don’t own it
@@Mellow_labs make sense 👌
Hi, where I can buy the pump?
I can’t give you a link, I found it in a scrub pile.
They can be pretty expensive, I would recommend trying to print your own or go to a scrapyard and try to find one.
9:28 🤣 The amount of times ADHD, made me over engineer the projects i had planned, fun 🙂
straight up using markers on your pc monitor is CRAZY my guy, what the hell
Some people like to watch the world burn 🔥
💖💖💖💖
Is it not a peristaltic pump instead of periseptic?
2:12
Yes sorry, words are hard.
Ur welcome :) happy to support you.
If you are going through the effort to have it dispense the detergent which takes 35s ... link it to state of the washing machine.
So if you turn on the washing machine, it auto dispenses.
Realistically you can leave detergent in the holder - it wont do anything - so you could have it auto dispense at the end of a cycle.
So next time, you just turn on the washing machine and it is already instantly ready. And when it is done, it's ready for the next load automatically :)
Yeah good idea. Personally, the 35s as it slowly dispenses.. it would drive me crazy
@@kartoffelwaffelyou don't need to wait for it to be finished to start the cycle I guess.
@@tiloalo good point
The middle chamber doesn’t get rinsed until 10 minutes into the wash, so I turn it on and push the button at the same time.
Wouldn't it have been easier to use a valve and put the bottle upside down on the shelf above?
Am I tripping, or did you actually draw on that monitor? It's not even a glossy one
Everything is a whiteboard😂
support comment
i am building custom alcohol drink mixer .... have 9 peristaltic pumps, trying to do all "coding" in home assistant ... and oh my god .... :D hope it will be finished in like one year ... i don´t know how to code :D and those peristaltic pumps don´t hold liquid ... so i have to move backward amount of time to empty all tubes (not having unknown amount of liquid) then go forward (time to make tubes full + time to dispense desired amount of liquid) and then go backwards because of droplets .... and then do this in right sequence :D
Jesus Christ, I would not want to do that inside of Home Assistant. I would be petrified of being an update away from it getting bricked. I would rather do it as a standalone system and add Home Assistant functionality later on.
@@Mellow_labs i can't i am to far in home assistant addiction ... i have around ten esp32 just in case of an idea ... :D
Washing machine in kitchen? What about when it spins? What about possible waterleaks? Doesn't seem smart place
This is normal in England.
use just time to calibrate filling quantities NOT a good idea, because when bottle will be empty the more power you need to fill up the same amount .
It’s a peristaltic pump, so flow rate is constant regardless of bottle fill level
@@JTEE3D if suction side is too low you will need more power, then pump will rotate a little bit slowly
@@mostafagaberahmed6657 unless the viscosity of the liquid being pumped by a peristaltic pump changes, the rotation speed and thus the flow rate will remain constant. Peristaltic pumps are used in medicine to measure out doses, albeit with a closed-loop optical encoder system. Mellow’s approach is perfectly fine for the non-mission-critical task of putting a bit of detergent in a washing machine
Glad my washing machine comes preinstalled with an ESP32. Which dispenses soap. Otherwise, I guess I would have built that. :)
Btw: The whole app thing is great on it. Not because I don't wanna use the buttons in front, but because it got like 200 programs with special settings for everything you can imagine. :)
"while True" but I have always learned that while(true){...} is the correct way. This isn't C or???
It’s Python in the beginning, but then it’s written in c++ for ESPhome
@@Mellow_labs That explains it. Thank's for clarifying it.!
You look like Snowden.... are you his body double?
I have completely different face structure to him, and the hair is completely different.
I find the advertising misleading that claims to get rich by selling detergent.
We at Mellow_labs pride ourselves for listening to our community, your feedback will be taken into consideration. 😂
Now you can wash all of your rainbow flags automatically.
drawing on monitor should be a normal thing!
Don't show the blades of your keys in videos. Might not matter now but a good habit to have.
I tried to avoid it, but sometimes I don’t put them in the right space.
@@Mellow_labs You have a 3d printer and probably two magnets somewhere laying around. ;)
The need, a smart dryer.
Air in the dryer becomes saturated with moisture and your clothes stop drying, extending the time it takes to dry your clothes.
To remove the moist air in the dryer, I stop the dryer and open the door to let the moist air out, every 5-8 minutes. This reduces the dry time by 50% compared to letting the dryer function without interruption.
I could potentially do that project, but it won’t be for a little while. I don’t currently have a dryer.
You either have a dryer that works differently from the 2 kinds I know exist, or have a problem with your dryer
The 2 kinds I know are:
1. pull in ambient air, heat it, push it out a tube.
2. Heat air in drum to dry, and condense the moisture into a water collection compartment
If you need to open the dryer to let moisture escape, there's likely something wrong. And it could be a fire hazard, depending on the type of dryer and actual cause- that aside too, sounds like horrible efficiency
@@davidl6566 This is how I function at commercial wash and folds. Instead of spending $1.50 or $1.75 on a dryer that I don't open. I spend only $0.75 and open the dryer after each quarter is completed to achieve the same dried state.
Your button wiring is confused. It is more normal to use a resistor to current limit the logic voltage, then the button pulls that current limited source to ground. This technique gives better noise immunity, also a small value capacitor can then be wired across the button if pickup from the motors is an issue. Your 3D printing and design skills are good, but you seem to be marginal on the electronics aspects of this project in my opinion.

had a little chat with chat gpt now i have to continue reverse is basicaly to unprime pump as it does not hold prime and i can allways start with known amount of liquid ... now i know that to prime pump it needs to run 12 seconds + actual dosage time .... homeassistant is quite fun when you start exploring and see that it does something that you actualy want it to do :)

cool, but why were you drawing on your monitor with markers like a complete psychopath
Now that I think about it was probably stupid to use a permanent marker 😂😂
Sorry, can't help but comment that you're cute.
😊 thank you
