Arduino UNO transparent case

I wanted to have a protective case for Arduino. I got this cheap (less than $2) Transparent Acrylic Shell Box For Arduino UNO R3 Module Board. Everything was packages to this small plastic bag. After installing eight screws and protective films from the plastic parts, everything was ready. I must admit that it takes some

Radar motion detector

I needed a motion detector for Arduino. I saw a cheap Microwave Radar Induction Switch Human Motion Sensor Module at DX (similar also available at Banggood at pack of 5). It advertises High Sensitivity for Arduino, Long Sensing Distance, Wide Sensing Angle for Detecting Moving Objects. Using this is a microwave sensor module that specifically

Hakko 191 soldering iron meter

I got this “Hakko 191″ soldering iron temperature meter from Banggood some years ago. It is not available there but you could find similar devices from eBay etc.. According to Hakko official pages the model 191 TIP THERMOMETER has been discontinued maybe years ago. This is most probably some Chinese clone of the device because

Metal detector kit converted to Arduino sensor

I got a cheap DIY Metal Measure Kit Electronic DIY Soldering Exercise Board with the following specifications: Model: MDS-60 Working voltage: DC3-5V Standby current: ≤ 5mA Working current: ≤40mA Measure depth: ≤ 60 mm Measure alarm mode: sound, light PCB size: 86 x 61mm There was a just the circuit board and some components on

Fiber visual fault locator videos

Last year I made a posting on Cheap fiber optic visual fault locator. It told about 1mW 5KM Red Light Pen Visual Fault Locator Fiber Optic Laser Cable Tester Meter puts out highly visible red light into a fiber optic cable that has ST, SC and FC optical connectors.The universal fiber connector worked well with single-mode

Digital Voltmeter AC 20-500V

I wanted to add an AC voltage meter to my electronics lab variac transformer output (0-275V AC). I decided to get a cheap Machifit AD16-22V 22mm Digital AC Voltmeter AC 20-500V Voltage Meter Gauge Digital Display Indicator with the following Specification: Model AD16-22V Mounting hole 22mm Voltage AC 20-500V Class of safety protection IP65 Color

LED lamp with UPS tested

I got several LEXXA 7W LED-VARAVALO bulbs in hoping to replace some aging LED light bulbs with new ones that have a bonus feature: They have an internal battery that allows them to output light even when the mains power is turned off. Those were available cheaply from Finnish shop Motonet (bulbs with pretty similar

Zyxel gigabit switch

I decided to replace my aging Zyxel and Netwjork 100 Mbit/s Ethernet switched with new gigabit models. I decided to get two ZyXEL GS-108S v2 Media Switch as replacement for those. The Zyxel GS-108S v2 10/100/1000 Mbps switch is designed to provide reliable high-performance media network connectivity – that’s what I need. The Zyxel GS-108S
