There was an engineer I met who gave me a laptop with Altium 09 on it and told me that if I could get him the gerbers for a fun kids' soldering project for the STEM booth, he'd hire me as his EE. He let me know that he wanted silver teeth and spoke about layers and silk screening - his eyes glazed over - but I accepted the challenge, as I had no idea what a Gerber was at this point. I took it on, fumbled through and figured out how to use Altium and TxRex was born! The second pic is 6 months into my Altium experience. Love this stuff! submitted by /u/gotoline10 [link] [comments]

It was a fun project for one day, the idea came from the thought "what circuit can I fit in the one box of matches?" So I did, the boards fit, of course, without the battery. I kind of like this "naked" look of it. submitted by /u/TmxFsd [link] [comments]

Check out this link for On Semiconductor’s datasheet for a line of “Zero-Cross Optocoupled Triac Drivers.”

The ability to zero-cross when turning on AC line voltage to some loads may be advantageous. The following sketch in Figure 1 is a slightly simplified version of one circuit from the above datasheet.

Figure 1 A simplified triac drive arrangement that will turn on AC line voltage to a load.

The zero-crossover behavior of the triac and its driver operates nicely as the control input signal at pin 2 decides if AC is applied to the node or not. However, I had a somewhat different triac control requirement calling for two manually operated pushbuttons, one for turning AC power on and the other for turning AC power off while preserving the zero-crossover feature. Another issue was that at the required load power, the thermal burden to be borne by the controlled triac was much too severe.

The thermal burden on the triac was relieved as follows in Figure 2.

Figure 2 The revised triac drive arrangement with a relay added such that when the pushbutton is pressed, the triac turns on AC to the load using its zero-crossover feature.

A relay was added whose coil was tied in parallel with the load and whose normally open contacts were in parallel with the anode and cathode of the triac.

When the pushbutton was pressed “on,” the triac would turn on AC to the load using its zero-crossover feature and then the relay contacts were closed across the triac. When the relay contacts closed, the load current burden was shifted away from the triac to the relay. The triac only needed to operate through the duration of the relay’s closure time which in the case I was working on, was approximately 50 ms or just a little longer than three cycles of the input AC line voltage.

We had the zero-crossover benefits, and the triac never even got warm.

One normally-open pushbutton for turning on the load’s power was set up to drive the LED at the input of the optocoupler. You can come up with a million ways to accomplish that, so we’ll just leave that discussion aside.

Another normally-closed pushbutton was set up to remove the drive from the relay’s coil. With the first pushbutton assumed to be open and idle at that moment, and since the triac was already off, the second relay’s contacts would open up, and the load power would be turned off.

India has provisionally retained tariff-free access to the U.S. for select electronics exports—including servers, laptops, and smartphones—due to an ongoing Section 232 national security investigation. While Washington has imposed broad 25% reciprocal duties on most Indian goods starting August 7, 2025, these electronics remain exempt for now, offering India a notable competitive advantage in the U.S. market.

Industry Reaction and Strategic Timing

The U.S. directive imposing tariffs is scheduled to take effect on August 7, 2025. India exports shall, however, remain unaffected for now because Section 232 is under review. Hence, the U.S. continues to facilitate duty-free exports of smartphones, computers, servers, and several other tech goods.

The move has been hailed by the industry organizations and analysts, who also compare that China faces effective duties of up to 30% on similar electronics exports to the U.S, while India (that is alongside Vietnam and Taiwan) continues to enjoy the zero tariffs, thus making their electronics at times 20 percent cheaper to compete with in the U.S. Market.

Increased Exports and Mid-Term Prospects

Electronics exports of India have been on a fast track; from around $8.4 billion in FY19 to $23.6 billion in Electronics exports have been growing rapidly in India: Whereas exports stood at around $8.38 billion in FY19, they touched $23.61 billion in FY23, with mobile-phone exports now accounting for more than half of total exports. Assembling of iPhones in India constitutes a significant piece of the pie.

Most Indian exports will face a 25% tariff starting August 7, 2025, with electronics temporarily exempt under Section 232 review. All Indian exports now face a 25% tariff starting August 7, barring electronic items. The tariff relates to Washington’s concerns concerning Indian trade barriers and India’s ongoing defense and energy ties with Russia.

Experts warn that should the Section 232 exemption be lifted, the Indian electronics exports would face sudden cost pressure, particularly in the American market. Practically, the move may curtail Apple’s plans to scale up India-based production of iPhones and thereby fast-track changes in global supply chains.

Government & Industry Positioning

Top trade officials emphasize that Section 232 continues to be reviewed, keeping India in a temporary window to consolidate export momentum.

The Commerce Ministry reiterated that in the negotiations, it remains firm to protect national interests and whistles down all policy options to defend India’s exporters and MSMEs.

Industry associations such as ICEA stipulate low-duty reciprocal regimes on U.S. imports of electronics to keep both countries competitive U.S. tariffs are currently about 16.5% in India, while those in the U.S. are almost zero.

Conclusion:

India enjoys its present position in electronic exports due to a temporary but crucial tariff exemption. The next two weeks will determine if this carve-out will be Permanent under Section 232, or if Indian tech products will soon be faced with the harsh tariffs. Negotiations for a wider Bilateral Trade Agreement (BTA) could probably lay the ground for a more expanded solution by September 2025, which would highlight concerns for tariff reductions, digital-trade access, and regulatory fairness.

For now, Indian exporters have the advantage of a preferential footing but may have to be nimble enough in the coming months to adapt to the probable changes in U.S. trade policy.
