Airchains, a Web3 middleware SaaS platform announced partnership with West Bengal’s New Town Kolkata Development Authority (NKDA) to transform the land ownership and mutation system by employing blockchain. This initiative will reshape the landscape of land mutation by introducing 500,000 Non-Fungible Tokens (NFTs) deployed on Polygon Supernets. Revolutionizing the land mutation process across 27,000 acres, this will replace traditional bureaucracy with a transparent, efficient, and secure digital system. The blockchain model also facilitates fractional property ownership, opening up to 10 lakh new mutation opportunities. This innovation is poised to redefine real estate transactions, increasing accessibility while significantly reducing fraud.
This land mutation record will stimulate a highly secure digital environment with unique NFTs serving as land ownership proofs for all properties under the jurisdiction of NKDA as well as enabling lifetime tracking of concerned ownership. This solution will allow easy transfer of ownership rights for landowners by transferring the corresponding NFTs, thereby eliminating complex paperwork. It will enable digitization of proof of records as distinct NFTs, updation of NFT records in cases of transfer, recovery of records in case of loss, and will prevent evasion of mutation charges. Acquiring physical copies of these NFTs include a printout in a card format possible via any printer. The digital certificates would further contain QR codes that will allow quick and easy access after authentication.
“New Town Kolkata stands as an extraordinary project, where every land detail is exclusively managed by HIDCO, acting on behalf of the state government. This distinctive arrangement provides us with a remarkable advantage in the land market, supported by a decade’s worth of meticulously documented records. Our aim is to revolutionize the real estate sector by introducing transparency akin to the financial system, ensuring effortless transactions for the masses.
Through our partnership with Airchains, we can transform our exceptional advantage into a tangible force in the land market. Our objective is to streamline the process of buying and selling land, eliminating the inherent challenges associated with such transactions. To accomplish this, we have identified NFTs as the perfect solution, as they enable the physical tokenization of properties, simplifying the entire procedure.” Debashish Sen, IAS (NKDA Chairman)
This landmark movement towards adopting and leveraging blockchain technology in government processes demonstrates the State Government authority’s commitment to being transparent, efficient, and open to new innovations that can streamline governance while improving the life of their citizens.

Festive failed filament finder

Every January my household, like many, undertakes the packing away of yuletide wreaths, trees, ornaments, and other holiday paraphernalia. One of the least fun of these chores is fixing strings of series-connected miniature incandescent lamps in which a filament has opened up, the internal filament-bypass device has failed to work, and a whole array of 50 or 100 lights has consequently winked out. This of course leaves the open-circuit-culprit visually indistinguishable from its innocent unpowered siblings. There aren’t many activities as well-calculated to dampen any lingering holiday cheer, and promote its Grinchy opposite, as having to do several of these frustrating haystack/needle searches.
Wow the engineering world with your unique design: Design Ideas Submission Guide
The festive failed filament finder (FFFF) design idea seeks to ease the annual pain by speedily sniffing out defective bulbs (and/or their sockets and wiring) by capacitively sensing the electric fields they produce. See Figure 1.
Figure 1 Failed filament finder circuit that capacitively senses the electric fields defective filament bulbs produce.
To understand how the FFFF works, consider a string of bulbs with an open-circuited filament as depicted. Intact filaments on either side of the burned-out bulb complete continuous circuits from the AC plug all the way around to opposite ends of the broken filament. The AC voltage differential between wires leading to any intact bulb is zero, because current flow through the broken string is zero. But the differential between the connections to the defective bulb will be the full 120 Vrms. The presence of 120 VAC on a wire produces large electrostatic fields that are easily detected through air and plastic insulation. The high-impedance CMOS inputs of “XOR” U1 can do just that.
Resistors R1 and R2, in addition to delivering operating power to the circuit, effectively suspend U1 midway between the AC supply rails. Thus, equal-amplitude (170 Vp-p) but opposite-phase voltage differentials will exist between U1 and both AC rails. R4 and C1 reference U1 pin 2 to AC “hot”, while R3 and the “Test” electrode are used to capacitively probe the voltages present in the wires of the bulb string. U1 then performs as a phase-sensitive detector of those AC voltages.
Suppose the FFFF Test electrode is held close to point A. Because A is continuous with the “neutral” rail, the signals at U1’s inputs will have opposing phases. One input will be high (logic one) whenever the other is low (logic zero). This causes XOR U1 to hold pin 3 high, so the three noninverting buffer elements do likewise to their output pins, and D2 glows. If the probe is moved to points B or C, the same phase relationship will persist and D2 will still glow. But if the probe is brought near D, the sensed phase will reverse because the circuit break lies between D and the neutral rail.
Consequently, “hot” phase voltage is induced in the probe. Pin 3 will therefore go low, extinguishing D2, lighting D1, thus pointing the fickle finger of fate at the offending filament. The defective lamp can then be “merrily” replaced.
In actual use, when the bad-bulb search is commenced, the initial phase relationship will be arbitrary, so either D1 or D2 may glow. In either case, it’s the sudden change in which LED is lit as the probe is moved along the string that indicates when the broken filament has been found.
A word about voltage detector pens.
An alternative method for fixing defective decorative light strings (several instructional YouTube videos exist that promote it) involves non-contact voltage detector “pens” to find where in the string AC voltage is present, where it is not, and use this information to infer the location of a bad bulb. In the videos this method seems to work well. However, in said videos the string being tested is invariably conveniently stretched out on a countertop with the wires separated and easily identified as to where they fall in the connection sequence from plug to bulb to bulb. This allows an amplitude-sensitive voltage probe to be selectively brought near a chosen wire without undue interference from other wires.
Unfortunately, many real life light string repair scenarios involve strings permanently installed into decorations like trees and wreaths. This prevents free access and the following of interconnections, making testing more difficult and indications from an amplitude-sensitive probe ambiguous. This largely defeats the utility of such probes in this context. Cue the Grinch!
The phase-sensitive detection method utilized by the FFFF, by contrast, is much less vulnerable to confusion from, and works in spite of, these complications.

Indian Government cuts down GST rate on Electronics
The Finance Ministry of India announces a huge reduction in GST for electronics items on the sixth anniversary of the GST implementation on 1st July.
The Union Finance Ministry recently made an announcement regarding a reduction in Goods and Services Tax (GST) on the purchase of electronic items. This decision aims to provide relief to customers and make these purchases more affordable. On the 6th anniversary of the implementation of GST, the government released a list of items that will have reduced GST rates.
Previously, customers had to pay a GST of 31.3 percent on electronic items such as TVs up to 27 inches, refrigerators, washing machines, geysers, fans, coolers, and electrical appliances like mixers, juicers, and vacuum cleaners. However, the new list lowers the GST rates on these items to 18 percent.
Furthermore, the GST rate on mobile phones has been reduced from 31.3 percent to 12 percent. Consequently, mobile phone companies will also decrease the prices of their products.
The implementation of GST laws by the central government on July 1, 2017, was a significant milestone in streamlining India’s tax system. It replaced the complex network of taxes with a simplified framework consisting of distinct tax slabs of 5 percent, 12 percent, 18 percent, and 28 percent for goods and services.
In other news, the gross goods and services tax (GST) revenue collection in India for the month of June reached Rs 1,61,497 crore, showing a 12 percent increase compared to the revenue collected in the same month last year, according to the Ministry of Finance. The gross GST revenue collected in June 2023 includes CGST of Rs 31,013 crore, SGST of Rs 38,292 crore, IGST of Rs 80,292 crore (including Rs 39,035 crore collected on import of goods), and cess of Rs 11,900 crore (including Rs 1,028 crore collected on import of goods). The government has settled Rs 36,224 crore to CGST and Rs 30,269 crore to SGST from IGST. After the regular settlement, the total revenue for the Centre and the States in June 2023 is Rs 67,237 crore for CGST and Rs 68,561 crore for SGST.
This marks the fourth time that gross GST collection has crossed the Rs 1.60 lakh crore mark. The average monthly gross GST collection for the first quarter of FY22, FY23, and FY24 is reported as Rs 1.10 lakh crore, Rs 1.51 lakh crore, and Rs 1.69 lakh crore, respectively.

Our SiC ecosystem also includes substrate research, development, and manufacturing in Italy and Sweden. In October, ST announced the expansion of our wide-bandgap manufacturing capacity with a new integrated SiC substrate manufacturing facility in Catania (Italy). The new facility is the first of its kind in Europe and is integral to our objective of achieving 40% internal substrate sourcing by 2024. ST is working on industrializing 200mm substrates, leveraging both engineering in Norrköping (Sweden) and the 200mm production line for SiC devices in Catania (Italy). ST is also cooperating with a technology partner, Soitec [Bernin (France)], to ensure a second qualified source of 200mm SmartSiC substrates, in addition to ensuring a robust internal supply. The collaboration with Soitec and their SmartSiC technology aims to advance SiC substrate technology and develop significant performance improvements that ST can deploy in high volume manufacturing. A final supply agreement will be subject to the qualification phase of the technology by ST and Soitec.
ELE Times: How do you list the benefits of using silicon carbide technologies across automotive and industrial sectors?
Gianfranco Di Marco: Power devices based on silicon carbide offer higher voltage and frequency capabilities than conventional silicon devices, allowing greater system efficiency, faster switching, lower losses, and better thermal management. In final applications, these advantages translate into smaller and lighter power designs featuring higher power density. SiC-based power devices can operate at up to 200°C junction temperature (limited only by the package), which reduces cooling requirements and allows more compact, more reliable, and more robust solutions. Existing designs can incorporate the performance and efficiency benefits of SiC devices without major changes, allowing fast development turnaround while keeping the BOM to a minimum.

Fibonacci and the golden mean

What we today call the golden mean was known in antiquity. It is a specific ratio of lengths between two line segments. Ancient architects often used this ratio to achieve visually pleasing esthetic effects.
Please see this Wikipedia article on the golden mean.
Even today, graphic presentations with width to height ratios made equal or nearly equal to the golden mean can lead to less stressful user viewing. For example, the 16:9 aspect ratio of the modern television screen is a ratio of 1.777…which as we shall see below is fairly close to the golden mean value.
With reference to two line segments called “a” and “b”, derivation of the golden mean goes along the following lines as shown in Figure 1. (Yes, that was a pun.)
Figure 1 Derivation of the golden mean with reference to two line segments called “a” and “b”. Source: John Dunn
Now take a look at the Wikipedia article on Fibonacci.
Fibonacci, was born in Pisa c.1170 and died in Pisa c.1240-50, was an Italian mathematician who introduced a mathematical concept we today call the Fibonacci series that goes like this (Figure 2):
Figure 2 The Fibonacci series is an infininite series beginning with the numbers 0 and 1 where each number is the sum of the two preceding numbers. Source: John Dunn
The increasing numbers in the Fibonacci series increase by the same algorithm as the segment lengths increase as shown in the golden mean derivation.
Since the square root of five is an irrational number, the golden mean is also an irrational number. Since the numbers in the Fibonacci series are all integers, the ratios of each number to the number immediately before can never exactly equal the golden mean, but as those numbers get larger and larger with greater quantities of significant digits with which to find their division ratios, those ratios do converge on the golden mean.
It is a tribute to Fibonacci himself that he is honored and his work is still remembered after eight centuries.
John Dunn is an electronics consultant, and a graduate of The Polytechnic Institute of Brooklyn (BSEE) and of New York University (MSEE).
