  1. @The Big B Dude you are an amazing person. Thank you. I was more meaning to light them all with one button without usbs, waterproof. But I will reverse your calculations and find what I need I used this powerbank just for leds before had no problems other than usb getting unplugged from vibration. Maybe I can be a little more optimistic and get like 60 mins life and this power bank? I have fake airpods case I could use for charging and for the button, waterproof it easily.
  2. Hi all, I bought four 1W Star LED's, specs are given below and I want to make a build in lighting system for my E-skateboard. The reason I do this is cause I do not want to remove lights to charge them and want to be able to switch them on from a single button. But I do not have enough electrical knowledge to build the circuit. I would appreciate if someone who has could draw a diagram for me and post it. I prefer using resistors over drivers which are easier to hide. It will be on for an hour maximum since the battery of the board runs out before that. Thanks in advance for your help. Materials: Power bank: 3.7V 4000mAh 2 Star LED (Tail Lights) https://tr.aliexpress.com/item/32918562594.html?spm=a2g0s.9042311.0.0.25ac4c4do1mtmm 1W 2.4-2.6V 350mA 2 Star LED (Headlights) 1W 3.2-3.4V 350mA 5V LED strip with remote. (This will work like neon lights under tuned cars which illuminate the road under the vehicle) I really want to include this into the setup also but if it is too much trouble I can eliminate it. https://tr.aliexpress.com/item/32813093650.html?spm=a2g0s.9042311.0.0.27424c4dz7pwsm I made some research online but could not find the info I needed for this specific setup.
  3. It didn't work. I think this time it was better but still it drains out water. I tried placing detergant tank higher this helped at low pressures but when I fully open the valve water is still coming out...
  4. Hello there I'm new to the forum. I signed up because of this problem I've faced. Wanted to ask you your opinions. So I've built a bottle washer for my homebrew beer kit. it work like I've described at the picture below. The porblem is There is water coming out of detegant tank intead of high speed fluid vacuuming it. I was expecting that but I also tought the water flow in the main pipe would suck the detergant when it is flowing. Any ideas how I can solve it? I got one described in pictur but its kinda hard to build from scrap. It would be great if someone could explain why it doesn't work and how can I make it work. (I can see it acts as just another hole in the tube squirting out water
