India seems to be adjusting its stance toward Chinese investment within the electronics manufacturing space. Government actions indicate a willingness to adopt a flexible and pragmatic posture, weighing both geopolitical and economic concerns.

Change in Engagement Strategy:

China continues to dominate the electronics supply chain globally, engaging in nearly 60% of worldwide electronics manufacturing activities. Under this recognition of interdependence on each other, India seems to be reconsidering its previous hardline approach to allow for strategic collaboration in industries of key importance.

Recent events, namely the restoration of tourist visas for the two countries and diplomatic engagement, have pointed toward a potential gradual thawing of bilateral relations. And this softening of relations on the diplomatic front seems to be reflected now on the industrial policy side, especially for electronics, where global collaboration matters.

The Dixon-Longcheer Deal:

The government turned its gaze onto this matter after it approved the joint venture between Dixon Technologies, a major domestic manufacturer, and Longcheer Intelligence, a Chinese ODM. The agreement states that Longcheer will own 26 percent of the business and Dixon will maintain controlling control. This framework reflects India’s intention to engage with Chinese companies through closely monitored minority-stake agreements.

Following this approval, it is understood that several other Indian electronics companies have developed a keen interest in forming similar joint ventures with Chinese technology partners.

Focus on Value Addition and Technology Transfer

According to the Indian government, Chinese investments will be allowed only if there is significant technology transfer involved and not mere low-level assembly operations. The Ministry of Electronics and IT (MeitY) stated that such collaborations should factor in the improvement of domestic capabilities and local value addition.

Proposal of Policy Reforms

In an attempt to ease out the process and bring down red tape, the NITI Aayog, India’s think tank, has recommended allowing up to 24% foreign direct investment (FDI) by Chinese firms in Indian electronics companies without requiring stringent multi-agency approvals. As these recommendations are being examined, MeitY officials have stated their support for them, citing their importance in attracting high-tech investments without endangering national security.

India is enjoying a window of opportunity with global dynamics undergoing shifts. With U.S. trade policy being uncertain and a reorientation on global supply chains, India seeks to be an important destination for electronics manufacturing. Strategic engagement with select Chinese firms would hasten the process of technology absorption at the component stage and create employment.

Indian leadership, meanwhile, continues to stress that such flexibility will be limited in scope, transparent, and oriented around the national interest. Any lifting of restrictions will be closely scrutinized with country-level mechanisms put in place to ensure that the long-term technological sovereignty and security of the country will not be jeopardized.

Conclusion:

Changing economic realities and investment in China in electronics by India show it as having an evolving approach toward becoming a true manufacturing center. This new stage of pragmatic economic engagement is characterized by an investment model that is more technology-focused and selective.

Yep, I’ve used 1970’s to 1980’s era parts from Japan and Taiwan only. The whole thing is built around a mitsubishi jungle IC. The controller is external though. I have no way of testing it because analog TV was shut down a long time ago here in Czech Republic. Just built it out of love and compassion for RF circuits. Fun fact: I’ve spent 6 hours just soldering all the components into their respective holes. There isn’t a single hole unused on that perfboard. submitted by /u/A55H0L3_WindowsXP [link] [comments]

Hey everyone! I’d like to share a fun and useful project I recently built: a PI-controlled soldering iron system based on a Hakko handle, designed specifically for heat insert pressing into 3D prints. You can enjoy this project from a few different angles: A DIY Tool That Actually Works I originally bought a so-called "digital soldering iron" to make a heat press, but it turned out to be fake—it just used open-loop power control with a 7-segment display. No temperature sensor, no feedback, no reliability. So I decided to build my own closed-loop system using proper RTD feedback, MOSFET switching, and a real PI controller running on an STM32. Now it gives stable heat control, perfect for insert work. A Showcase for My Snapboard Platform This project is also a working demo of Snapboard, my modular prototyping platform for embedded hardware. It’s like a LEGO base for breakout boards—strong and swappable, yet reusable across multiple projects. The potentiometer, OLED display, and power modules all snap into place cleanly with perfboard support. It’s been rock solid for building functional prototypes. A Control-Theory Driven Design Instead of trial-and-error tuning or just using bang-bang control like most DIY temp controllers, I took a full control engineering approach: Collected step response data Fitted it to a first-order model Designed the PI gains using pole placement, not guesswork Analyzed performance metrics like settling time, overshoot, etc. You can get a ready-to-go PI controller without hand-tuning. I even wrote a short doc on the theory and design [Notion link here].

There have been numerous circuits published in EDN as design ideas (DI) for the past few months, centering around the “Flip ON Flop OFF” circuit originally published by Stephen Woodward. These are all designed for DC voltages less than 15 V, since this is the maximum power supply voltage of the CMOS ICs that were used in their design.

Wow the engineering world with your unique design: Design Ideas Submission Guide

There are several applications that use 48 VDC as the supply voltage, such as telecom equipment, solar panel controllers, and EV controllers. In general, DC on/off switches are bulky, as there is no current zero-breaking concept as in the case of AC circuits. A DC on/off switch will break the full load current, leading to arcing and contact erosion. Because of this, bulk-sized switches with higher current capacity are employed.

Figure 1’s circuit can flip on and flop off 48 VDC with a tiny push button. D1 is a 5.6-V Zener diode. It is connected to the base of the Q2 transistor. Its emitter voltage becomes around 5 VDC (Vz-Vbe).

ICs U1 and U2 operate with this 5 VDC voltage. When the pushbutton (PB) is pushed once momentarily, a small pulse is generated, which is counted by U1. Its LSB pin becomes HIGH, which is applied to the gate of Q1. Hence, it conducts, and the output gets 48 VDC. For the next push of PB, the LSB pin of U1 goes LOW, and the gate of Q1 becomes LOW, and Q1 stops conducting. This makes the output voltage go to zero. This action repeats for every push.

Figure 1 The flip on, flop off circuit for 48 V. The output gets 48V DC when you push PB once momentarily. For the next push, output becomes 0 V. U1 and U2 operate at 5VDC only. Connect the Vcc pins of U1 and U2 to VDD and the ground pins to VSS, as shown in the above circuit. Use heat sink for Q1 for higher currents.

Since PB encounters current around a milliamp, the low current, sleek PB is sufficient to switch ON or OFF the 48-V supply with high current. With a proper heatsink on Q1, this circuit can switch ON or OFF DC currents up to several amps as per the data sheet of Q1.

Both R1 and C1 are for PB switch debounce. Both R2 and C2 are for the power-on reset of U1.

If galvanic isolation is needed (this may not always be the case), you may connect an ON/OFF switch prior to the input. In this topology, on-load switching is taken care of by the PB-operated circuit, and the ON/OFF switch switches zero current only, so it does not need to be bulky. You can select a switch that passes the required load current. While switching ON, first close the ON/OFF switch and then operate PB to connect. While switching OFF, first push PB to disconnect and operate the ON/OFF switch.
