Mailbag june 2023

A new month just has started, time for a new mailbag post. Two products (The multi-meter and the component tester) where already discussed in separate blog posts. Most other items are for my new to build hobby space.
In this blog i also included the link to the Aliexpress page.

FNIRSI DSO-TC3 Component tester, Osilloscope and Signal generator
 Angen 683 multi-meter

Waterproof Tile Marker Grout Pen (White)

This is not an electronics product, however i decided to keep it in this mailbag list. (I left out some other items like shoes and a phone case.)
As i needed one and these pens where relative cheap i ordered two different at different resellers.

AC-DC 110-220V Switching power supply module AC-DC isolation input output 5V /12V /100mA /500mA

The description of this cheap small (35*25*15mm) power supply module module mentions that it has an input of 110/220 Volt and gives 5V 100mA and 12V 500mA.

I do not yet have a specific project to use it however to me it seems an interesting module. However before keeping it unattended connected to mains power i want to do more testing as sometimes these cheap modules sometimes can be dangerous.

In-line blower

Boat boat marine yacht 3inch In-Line Marine Bilge Air Blower Mute Strong Ventilation Fan for Yacht Boat RV rod

High-flow 128 CFM (3,800 liters per minute) capacity provides ventilation for the engine compartment, galley, bilge
25% more efficient than that of the traditional straight line blower, guarantees fast air circulation to improve air quality.
ABS plastic construction with built-in molded mounting brackets.
Corrosion proof design and water resistant motor casing for use in the marine environment. Hose connections each end, for use with 75mm (3in) diameter blower hoses.
Easy to install, either vertical or horizontal is applicable.
The installation and operation instructions are included. The mounting screws are not included and are used for intermittent use.

  • Item Type: Marine Bilge Air Blower
  • Material: ABS
  • Color: Optional
  • Voltage: 12V, 24V (I ordered the 12 Volt version) 
  • Flow Capacity: 130 CFM (Cubic Feet per minute) 3800 LPM (Cubic Liters per minute)
  • Current Draw: 2.5 Amp
  • Length: Approx. 8.0in (200mm) 
  • Width: Approx. 4.3in (111mm)
  • Height: Approx. 4.6in (116mm)
I don't have a boat , however i did see this product in some YouTube videos, also in a video where it was used to build a DIY fume hood.
I want to use in my new (to build) hobby space for (local) fume extraction when soldering, using glue or other items.
Perhaps i also will do some chemical experiments.
This item is only for fume extraction, not for dust extraction as it has no dust collector!
I did not test it yet, however according to the specs the airflow is 3800 LPM (Cubic Liters per Minute) = 3800*60 = 228000  liter/hour.
I don't know yet the size of my new workspace, however e.g. a  3*2.5*5 meter workspace = 37.5 m3 = 37500 liter. This would result in 228000/37500 = ~6 air changes per hour of that complete workspace using one of these small relative cheap ventilators. (Assuming no dead corners).

Adapter BNC Female Jack To MCX Male Connector Plug Connector

Ordered two of these connectors, especially to use with my
FNIRSI DSO-TC3 Component tester, Osilloscope and Signal generator
Wall Socket ethernet (6 port)

I ordered this 6 Ports RJ45 5e 6 Female To Female Faceplate Socket Panel For Internet LAN Cover Network Extender to use in my new (to build) hobby space.
Wall Socket with HDMI and Ethernet

Two Ports CAT6 RJ45 LAN Socket With 2x HDMI2.0 Female Plug Wall Panel In White Color also to use in my new (to build) hobby space.

USB connectors

10pcs 4Pin USB 2.0 Female Power Jack 2P 4P USB2.0 Charging Port Connector Data Interface with Cable USB Charger Sockets.
To use in project and also to make some fixed USB connections in my new (to build) hobby space

Lazy Suzan

Square Lazy Susan 360° Heavy Duty Metal Bearing Rotating Swivel Turntable Plate Desk Table Rolling Swivel Plates For Furniture
 Only this year i learned that this rotating bearing is called "Lazy Suzan". I want this to use in my new (to build) hobby space.

KVM switch

For 2 PC Sharing Keyboard Mouse Printer Plug and Play Out 4KUSB 2.0 HDMI-compatible KVM Switch Video Display USB Switch Splitter.
I wanted this to switch a screen between my laptop and a Raspberry 4 and it works perfect.
Before this i used a HDMI switch (and had 2 mouses on my desk. The keyboard was only connected to the Raspberry). However now i can also easy share my keyboard and mouse and use it on the laptop. For the occasions when i don't want to disconnect the screen from the raspberry pi and at the same time i need to do something on my laptop i use the keyboard and mouse-pad on the laptop.
