PCB: Smart Panelising: The Art Of Saving PCB Cost
Ordering a single piece of PCB from a manufacturer can be quite costly, especially when, for the same price, multiple PCBs could be manufactured and assembled. This is a common mistake made during initial product prototyping. Focusing solely on circuit design and being unaware of PCB panelisation, this error often goes unnoticed until later. Even for those familiar with panelisation, it is possible to produce 3 to 4 more units at the same production cost by making slight adjustments to the panel design.

CIRCUIT IDEA: LED Strip Dimmer And Call Bell
An LED dimmer circuit adjusts the brightness of LED strips, serving both as an energy-saving tool and a method to create aesthetic lighting. Call bells, designed to draw attention, are commonly used in various environments such as offices, hospitals and residential care homes. Here, we explore a simple 12V LED dimmer circuit, incorporating an LM556 dual timer IC, which also functions as a call bell. The LM556 dual timer IC houses two 555 timers within a single 14-pin package. In this LM556 PWM-based LED dimmer circuit, the brightness of the LEDs is effortlessly controlled using a potentiometer.

PROJECT: IndusBoard Standalone IoT Lidar Radar
Lidar plays a key role in cartography, mapping, localisation, ADAS, environment scanning, and more. It is widely used in robots, autonomous vehicles, and for intruder monitoring. However, many systems are wired, making them cumbersome for prototyping and testing, particularly in autonomous driving, where mounting and connecting a lidar can be difficult.

PROJECT: Electronic Digital Piano
Pianos and many other musical instruments have now been digitised. They can now be replicated using electronic circuits. This device converts traditional pianos or other instruments into digital forms using electronic components. The source code can be modified to create various digital instruments, such as drums or flutes, by adjusting the output sound, tone, and frequency.

PROJECT: Wireless Remote Data Monitoring System With TFT LCD Monitor
Remote monitoring plays a pivotal role in advancing industrial automation, Industry 4.0, and the Industrial Internet of Things (IIoT). A remote data monitoring system (RDMS) continuously tracks parameters such as temperature, pressure, humidity, flow, and machine performance real-time. By collecting data from strategically placed sensors throughout an industrial plant and transmitting it to a centralised hub, this system enhances operational efficiency, reduces downtime, and ensures timely maintenance, thereby boosting overall productivity and safety.

CIRCUIT IDEA: Long Duration Timer Using Supercapacitor
When charging devices like mobiles and laptops, it is easy to forget to switch off the power once they are fully charged, often resulting in devices remaining connected to the AC mains supply for hours. A simple solution to this oversight is presented here. The circuit shown in Fig. 1 can automatically switch off any device connected to the AC mains supply after a period ranging from one to over four hours. Extending the delay period is possible by adjusting the values of the resistors used in the circuit.

PROJECT: Mobile Hotspot/Tethering Unit Charging Using ESP RainMaker App
Connecting to a wireless LAN network is a popular option for accessing internet-based applications. A readily available alternative is tethering or using a mobile hotspot, which allows the sharing of a smartphone’s mobile data to connect other devices to the internet. Most Android smartphones offer the capability to share mobile data through Wi-Fi, Bluetooth, or USB. Tethering effectively transforms a smartphone into a Wi-Fi access point, providing connectivity for laptops, tablets, microcontrollers, and low-power systems-on-chips (SoCs).
