We have new product in stock:

WATER-VALVE-6.5MM-12VDC

WATER-VALVE-6-5MM-12VDC is electro-magnetic valve with normal closed path. It’s driven with 12VDC/0.54A and when power supply is applied opens the valve. It has quick connect for 6 mm sleeves and makes water/air pipes attachment and dis-attachment easy. The valve can work with 0-0.8MPa (0-8 bar, 0-116 psi, 0-7.9 atm) pressure of the air or water.

With this valve and ESP32-EVB you can make IoT watering system, which allow you to switch on and off water supply to your garden or plants via internet.

The demo code is written with Arduino for ESP32-EVB and sources are at Github.

When the server is run you can view the status in your local network:

DIY Air Pockets Machine

Image

When dealing with shipping parcels there is one thing which is always not enough – filling material, it should be light to not change the parcel weight, but must in other hand fill all gaps and hold the materials inside the parcel tight to not break during the shipments.

After searching for professional machine for making Air pocket I found that all of them are

  1. expensive
  2. working with special materials which are also expensive

so I start thinking how to make my own air pocket filling machine.

First thing was to find PE sleeve, it was not hard as around Plovdiv there are about 10 different small factories which produce such PE sleeve, they can even print your logo or something else on it as it’s widely used to pack milk, sugar, and so on food products.

The PE sleeve is sold on KG and very cheap, this roll you see above is 6KG but probably long thousand meter and cost me eur 30.

Then I needed PE sealing machine and sourced one from ebay for $40 with free shipping.

The sleeve should be also filled with air so I got one of these small fans used in bathrooms.

So I was ready to test my “machine”.

First cut one stripe of the sleeve around 1 meter and sealed one end with the sealer.

Then put the sleeve on the fan fixing it with rubber ring:

As expected the sleeve got filled with air then all I had to do is to seal some pockets with the selaer. You can see the result:

Not bad result for first try 🙂

Now I have unlimited low cost air pocket filler for the parcels we ship.
