Any idea what is that water level sensor there? I've been trying to figure that myself but couldn't

Hi i know this is an old Video, but I have the RS PRO HS608, which is the exact same meter re branded, but misplaced the charge adapter thing that plugs into the front, anyone know of a place to get one, I've tried google and RS, or is this adapter just a simple device that can be made up ? Cheers in advance

Really nice video! I especially appreciate the measurement part. I'm designing my own PH circuit at the moment so this was helpful

Commenting on a nine year old video, I assume you got all this nailed down already! One idea I had while watching was a "mix tank" where you can confirm the dispensed nutrient quantities before they are added to the main tank. It would a small tank seated on high resolution load cells, and the new weight can be checked after each nutrient is dispensed. This would double check the flow rate and cut off of the peristaltic pumps and ensure nutrients are going out. If you expect 5ml of nutrient D to enter the mix but the mix pot only goes up by 4g, there's an issue, etc etc. Once everything is accurately dispensed into the pot, it can be pumped or tipped into the main tank. Now I'm going to check out your other videos and see how you go on.. This is like finding a "new" old TV series to binge 😂

Why not use reverse osmosis to remove the chlorine?

Whats is the thickness? If i use 1mm thickness will it work?

Really interesting and love the quality and time lapse. What's the final verdict on DE for you and your plants?

Thank you!

Aoyue..... "ay you" or some say "ay o you"

£1 those were the days eh? Just ordered myself another Mini and it was £4.20. Still cheap, but 4 times the price in 9 years

Great video!😱 Wow, to see exactly what it looks like. I use Diatomaceous Earth, wet and dry. Please make more like these?

Interesting … but all the conclusions are incorrect … logically pests and parasites EAT diatomaceous and then with its sharp and interlocking shapes it basically sets in the stomach of say silo insects or even parasites in the body .. This logically is the only way it works so I thought I should mention the obvious here …

This has a rather worrying similarity to Nick Park's movie "The Wrong Trousers."

I needed 3 items to clean up multi-ganged potentiometer: screwdriver to open box, chopstick with taped to it q-tip and 70% isopropyl alcohol. 1. Remove 4 screws on the bottom of the box. 2. Remove top and bottom plastic covers. 3. Soak q-tip in 70% isopropyl alcohol. 4. Between top and bottom PCBs reach with chopstick/soaked q-tip to the top on the potentiometer and brush it few times, so the alcohol can get into pots' tracks through top holes on them. 5. Rotate pot few times back and forward. 6. Let the alcohol evaporate. 7. Screw the box covers back.

Hello Jim, your 9 year old turtorial saved my cambridge soundworks digital theatre! came here to say thank you and i am glad you are still here with us!!! greetings from Poland :)

Fake stuff are everywhere. I was preparing for a trip to the UK and needed US-to-UK plug adapters. I went on Amazon and ordered a couple of different brands. I noticed one brand had a fuse whereas the other brand did not have a fuse. I did a little more investigation of the fused travel plug and learned that it was a requirement specially when using US devices in the UK. A little more searching on Amazon showed that many such plug adapters are not in compliance with BS8546 nor have a BS1362 type fuse installed. Travelers using unfused type adapter plugs are putting themselves at great risk should their device(s) develops an internal short circuit. Would hate to see the device external cable go up in flames.

Would this work for thrips and spidermite? Thank you .

Fantastic! Amazing explanation, fun and real deal! Subscribed

Thanks. I guess only missing part is mosfet selection. IRF5305 or IRF9Z34N which I have for some reason is not ideal if microprocessor operates at 3.3V or so (lifepo4, 3xNiMH, li-ion, ...). Few years ago I bought a few TP0606N3-G and LP0701 ... not sure why exactly these, they have quite high on resistance, but vgs(on) is 2.4 or 0.7V. Ok, after experimenting, TP0606 draws about 1-3uA depending on VCC when it should be off (maybe it always conducts a bit), has higher resistance and it's likely discontinued.

5 amps? That's pathetic. I wouldn't even use that fire hazard as lamp cord in the United States. All it's good for is a fire starter. I wouldn't even use it for speaker wire.

If I buy a product with the illegal lead can I but a legal version of the lead and still be usable?

I needed a hotter tip and ended up using an adapter with variable voltage set to 7.5v I use it for plastic repairs on car interiors and needed hotter melt to ensure adhesion to old plastic. Works great, but I really wanted to use 1.75 as sticks of 3 are so expensive. I bought rolls of 3mm but had to hand bend pieces and was tired of breaking and having to push it through when a kink didn't feed properly. I bought the 3doodler flow to take advantage of the 1.75 but it isn't hot enough either. Unfortunately it doesn't allow a plug in adapter, has a permanent cord coming out of it. I'm about to splice it and try to rig it to my adapter, don't care if I break it, I need it hotter or it's useless

Came for hydroponics now I'm raving to these beats wow

The music was great! Hard to find Ryan Grenz Monsoon though.

Neem oil works good

Mis leds, mas de 11 años funcionando. Sólo te falla un par de cosas, tipo control de humedad (lo solucionas con una lente convexa incorporada hermeticamente) y la alimentación constante de 12v (o incluso un poco menos) del ventilador secundario (unido al disipador) para darle desde el driver constante los correctos rangos de potencia y amperaje.

Nice office.

You missed getting the optical mirror out .... that's where I got stumped ... lol

How we can connect with another planet wuth the hekp of computer, voice equipment & satelite

Hi,what amp ic use this. Thx tou.

Please activate subtitles. thanks.

8yrs later the little buggers are still playing in the D.E!

Can you give us conclusion on your exprience with DE? Was the DE dusting an effective method of controling the pests in your garden? Thanks!

The pump you showed on that site appears to be different from the correct one. Did you figure out which one it is? SI-P007 or SI-P005 looks to be a closer match, but I can't tell which of those two is correct. I need one as mine barely blows and its barely used.

Great to see you back man , nice trippy tune , have fun

Hi jim, after repair, the cambridge system worked fine. But now after years I am working on it again. I now wanted to make nails with heads(I don't know if that's what it's called in english) and replace the two big capacitors, one in the power supply and one on the PCB, although visibly nothing is wrong, we'll see what it gives ;-) ferdi

Hellow, Can you please explain me the use of two diodes here. If we use one controll pin from arduino it will turn on when the button pressed(if the code has written to turn high the controll pin in void setup function) and keep the mosfet on no? So what is the use of getting state of switch? Thank you

Wanting to do something similar, how did it end up?

7 years later I'm wondering what you thought I'd wonder.

Brilliant intro! I nearly fell for it

I have of these Jim, it's unmarked but looks like chip 2. Are the datasheets still available? Regards Alan.

Good to see you again Jim. That was out of this world. and very compelling viewing. Cheers Patrick.

Neat! Was worried about you. Glad you're still around :) How's the garden? Cheers

Per aspera ad astra

Not sure what you're trying to communicate here, but great to hear you're still with us, Jim!! :) Very pretty, love the psychedelic vibe!

We put over 650 hours into the music for the album, and another 30+ making this video - The project has been a labour of love and I'm very pleased to finally deliver it into the world. Enjoy!!
