Hey all, I’m a 2nd year student in electronics right now. I know there’s tonnes of handwired keyboards on the internet, but here’s mine. This is my first time ever soldering or doing anything outside of arduino or simulations. So it’s very messy. After I finished painstaking soldering the diodes and columns, it turns out I need 19 pins and the pro micro has only 18. I thought my project was a goner, but I found the hack of removing the resistors in the leds to free 2 more pins. I’d never ever done soldering before, and was honestly scared about taking out the resistor from the board, but figured the project wasn’t going to go anywhere if I didn’t do it, so I took the chance and somehow managed to desolder the resistors and put in the legs of the diode which I cut off earlier! But but but, as soon as I started soldering it to a column to test, I ripped out the copper trace from one of the pins and though my project was a goner (again). Thankfully that hack gave me 20 pins, which means I had exactly 19 now (phew). Maybe you notice the red electrical tape on the switch, that’s because it was meant for the big L shaped enter key which I didn’t have, so I had to use the tape to fit the enter and |\ keys. Well, it works now; it’s not perfect, the board sometimes misses strokes when I use it because the wires the dangling out, and I currently don’t have anything to secure the back. But it works! I’m sorry if my body too long or not technical enough, I just wanted to share my work. When told we’re working on something, profs always ask its application and what issue it resolves. I spent a lot of time and energy on this and I have no answer to these questions, I made it cause I wanted to know how it works and cause I felt I should be able to make it, and I know it’s nothing special or solving any real issue and has a lot of documentation and YouTube videos to make the same. So, I’m just not sure if this work is “sciency” enough to justify it on my profile or even investing that much time into it. Welp, I had fun so that’s that. Sorry for the out of topic rant again. Let me know what you guys think! submitted by /u/Professional_Ice_796 [link] [comments]

Two touchscreen controllers join Microchip’s maXTouch M1 family, expanding support for automotive displays over a wider range of form factors. The ATMXT3072M1-HC and ATMXT288M1 cover free-form widescreen displays up to 42 in., as well as compact screens in the 2- to 5-in. range. Both devices are compatible with display technologies such as OLED and microLED.

The AEC-Q100-qualified controllers leverage Smart Mutual acquisition technology to boost SNR by up to 15 dB compared to previous generations. They deliver reliable touch detection even for on-cell OLEDs, where embedded touch electrodes are subjected to high capacitive loads and increased noise coupling.

The ATMXT3072M1-HC targets large, continuous touch sensor designs that span both the cluster and center information display, enabling a single hardware design for left-hand and right-hand drive vehicles. For smaller screens, the ATMXT288M1 is available in a TFBGA60 package, reducing PCB area by 20% compared to the previous smallest automotive-qualified maXTouch product.

For pricing and sample orders, contact a Microchip sales representative or authorized dealer.

Keysight’s Wireless Coexistence Test Solution (WCTS) is a scalable platform for validating wireless device performance in crowded RF environments. This automated, standards-aligned approach reduces manual setup, improves test repeatability, and enables earlier identification of coexistence risks during development.

To replicate real-world RF conditions, WCTS integrates a wideband vector signal generator. It covers 9 kHz to 8.5 GHz—scalable to 110 GHz—with modulation bandwidths up to 250 MHz (expandable to 2.5 GHz). A single RF port can generate up to eight virtual signals, enabling complex interference scenarios without additional hardware. Nearly 100 predefined, ANSI C63.27-compliant test scenarios are included, covering all three coexistence tiers.

Built on OpenTAP, an open-source, cross-platform test sequencer, WCTS delivers scalable and configurable testing through a user-friendly GUI and open architecture. Engineers can upload custom waveforms and validate test plans offline using simulation mode, accelerating test development and reducing lab time.

More information about the Keysight Wireless Coexistence Test Solution can be found here.

The first device in AOS’ αMOS E2 high-voltage Super Junction MOSFET platform is the AOTL037V60DE2, a 600-V N-channel MOSFET. It offers high efficiency and power density for mid- to high-power applications such as servers and workstations, telecom rectifiers, solar inverters, motor drives, and other industrial power systems.

Optimized for soft-switching topologies, the AOTL037V60DE2 delivers low switching losses and is well suited for Totem Pole PFC, LLC and PSFB converters, as well as CrCM H-4 and cyclo-inverter applications. The device is available in a TOLL package and features a maximum RDS(on) of 37 mΩ.

AOS engineered the αMOS E2 high-voltage Super Junction MOSFET platform with a robust intrinsic body diode to handle hard commutation events, such as reverse recovery during short-circuits or start-up transients. Evaluations by AOS showed that the body diode can withstand a di/dt of 1300 A/µs under specific forward current conditions at a junction temperature of 150 °C. Testing also confirmed strong Avalanche Unclamped Inductive Switching (UIS) capability and a long Short-Circuit Withstanding Time (SCWT), supporting reliable operation under abnormal conditions.

The AOTL037V60DE2 is available in production quantities at a unit price of $5.58 for 1000-piece orders.

Based on Rohm’s Nano Cap ultra-stable control technology, the BD9xxN5 series of LDO regulator ICs delivers 500 mA of output current. The series is intended for 12-V and 24-V primary power supply applications in automotive, industrial, and communication systems.

The BD9xxN5 series builds on the earlier BD9xxN1 series, increasing the output current from 150 mA to 500 mA while maintaining stability with small-output capacitors. The ICs provide low output voltage ripple (~250 mV) for load current changes from 1 mA to 500 mA within 1 µs. Using a typical output capacitance of 470 nF, they enable compact designs and flexible component selection.

All six new variants in the BD9xxN5 series are AEC-Q100 qualified and operate over a temperature range of –40°C to +125°C. Each device provides a single output of 3.3 V, 5 V, or an adjustable voltage from 1 V to 18 V, accurate to within ±2.0%. The absolute maximum input voltage rating is 45 V.

The BD9xxN5 LDO regulators are available now from Rohm’s authorized distributors. Datasheets for each variant can be accessed here.

There is a Neil deGrasse Tyson video covering the topic of the Chandra X-ray Observatory. This essay is in part derived from that video. I suggest that you view the discussion. It will be sixty-five minutes well spent.

This device doesn’t look anything like a planar mirror because X-ray photons cannot be reflected by any known surface in the way you see your reflection above your bathroom sink.

If you aim a stream of X-ray photons directly toward any particular surface, either a silvered mirror or some kind of intended lens, those photons will either pass right on through (which is what your medical X-rays do) or they will be absorbed. You will not be able alter the trajectory of an X-ray photon stream, at least not with any device like that.

However, X-ray photons can be grazed off a reflective surface to achieve a slight trajectory change if their initial angle of approach to the mirror surface is kept very small. With the surface of the Chandra X-ray mirror made extremely smooth, almost down to the atomic level, repeated grazing permits X-ray focus to be achieved. This is the operating principle of the Chandra X-ray Telescope’s mirror, as shown in Figure 1.

The Chandra Observatory was launched on July 23, 1999, and has been doing great things ever since. Regrettably, however, its continued operation is in some jeopardy. Please see the following Google search result.
