I was curious about the accuracy of this digital manometer and built a simple test stand to compare the meter readout to a classic water manometer. With an electric air pump controlled by a motor speed controller, I was able to generate variable air...
In order for your container to function properly you will need to make air holes at the top for oxygen to get to the upper electrode(cathode), as well as holes for the wires to exit the cell. I used a candle and a steel lab tool, anything sufficiently...
Reflow all solder paste using a hot air gun. There are many tutorials on this as well online. My main tip is to make sure air flow isnt too high where you have to worry about parts moving. Simply take your time and make sure all solder...
The valve is added to remove the vacuum once the switch is released, otherwise the hand would get stuck for a long time since the air would trickle in slowly. Add the right angle connectors to the valve, screw them with some teflon tape. Connect the...
Here are the air needles/hoses pressed into the measurement ports of the HRV, and the PICO board dangling off of the sensor (maybe I need a 3D printed case...). So - the pressure drop across the HRV core (stale air side), is sitting at about 17.5 Pa. ...
Use a [very] hot air gun, reflow, or heated wire to soften the holder's fingers and bend them round some wood. Remember to leave enough room for the phone, a phone case, the heads of the screws, and a little space to insert and remove the phone.
