we just got our UNO R4 WiFi, featuring the Renesas RA4M1 series of chips https://blog.adafruit.com/2023/05/25/eye-on-npi-renesas-ra4m1-microcontroller-series-eyeonnpi-digikey-renesasglobal-digikey-adafruit/ an ESP32 wifi co-processor, an adorable LED grid, and a JST SH 4-pin connector...a.k.a a Qwiic port! Yay it is so great to see this connector becoming standardized on so many platforms. It means that all of our STEMMA QT devices https://www.adafruit.com/category/1018 will work plug-and-play. Here we're testing it with an OLED https://www.adafruit.com/product/938 and SHT41 breakout https://www.adafruit.com/search?q=sht4 we only had to update our demo to use Wire1 instead of Wire, since the secondary I2C bus is used for this connector.

Buck-Boost Converters are power supplies that are 'ambidextrous' - they can convert lower or higher voltages to one steady output. A good idea for if, say, you have something that could be powered by USB or two AA's but you want 3.3V output. Much like the name implies, they can both 'buck' the voltage down, and 'boost' the voltage up. For our Toy Hacker board, let's try to find a low cost buck-boost chip that will give us about 500mA of 3.3V output even from two nearly-dead AA batteries that are 0.9V. We want something somewhat small and fairly inexpensive, efficiency isn't the most important since we expect folks to use rechargeable AAs anyhow.

This week we got the prototypes for our 'Toy Hacker' board that replaces the innard of a Baby Einstein take-along-tunes toy with our own tronix. we picked the esp32-s2 as a main core because it has wifi baked in, perfect for when you have a device that is fully enclosed like this one! using the CircuitPython WiFi workflow, we configured the wifi credentials and access password in settings.toml and it pops up on our network. now we can edit code, move files around, etc, without having to undo all those lil screws. This may very well be the first python powered baby toy!

This week's EYE ON NPI is going to fuel up your portable battery-powered designs with the Texas Instruments BQ27427 System-Side Impedance Track™ Single-Cell Battery Fuel Gauge (https://www.digikey.com/en/product-highlight/t/texas-instruments/bq27427-single-cell-battery-fuel-gauge) a powerful and inexpensive way to add high quality battery monitoring for charge-rate and aging tracking at the system side. Lithium Ion / Polymer batteries (https://www.digikey.com/en/products/filter/batteries-rechargeable-secondary/91) - you love them for their low cost, high power density, and 3.7V nominal voltage, but keeping them recharged and letting people know exactly how much battery life is left is non-trivial. Like most batteries, common LiPoly/LiIon's start with a high peak voltage right after charging of about 4.2V, drop quickly to about 3.7V and then slowly drift down till they get to 3.0V at which point the cut-off circuitry disconnects until they are recharged. It's really easy to tell when the battery is 90% or greater charge, just look for a voltage of 3.9V or higher. It's also pretty easy to tell when they're 10% or less, the voltage will be 3.3V or lower. But that in-between section is tough because the slope during discharge is very shallow and the voltage changes quite a bit with aging, temperature, and discharge rate (https://www.ti.com/lit/an/snva533/snva533.pdf) So while there are battery monitors that can use just the voltage across the battery terminals, they're not going to be as precise as a coulomb-counter design that takes into account both voltage and current. From TI's White Paper on the topic (https://www.ti.com/lit/wp/slpy002/slpy002.pdf): "An impedance-based battery fuel gauge, as the name implies, uses the measured impedance of the battery’s cells as a key input to its remaining capacity predictions. The gauge measures and stores in real-time the battery pack’s resistance as a function of state-of-charge. The real-time resistance profiles along with the stored battery open-circuit voltage tables (open-circuit voltage vs. state-of-charge) enables the gauge to predict the battery pack’s discharge curve (by adjusting for the IR drop) under any system-use condition and temperature. The algorithm uses current integration (coulomb counting) when the system is ON, and open-circuit voltage measurement when the system is OFF or in SLEEP to adjust remaining state-of-charge (RSOC) up or down (for charge or discharge) the predicted discharge curve. By using the predicated discharge curve, the gauge can accurately calculate the battery pack’s remaining discharge capacity (RM) and the system’s run-time to empty (RTTE). Since an impedance track gauge continuously adjusts RM and FCC for impedance and the change in impedance, rate and temperature inefficiencies and aging are inherently taken into account, enabling the gauge to maintain a high level of accuracy throughout the life of the system." Texas Instruments has a few chips in the Impedance Track family (https://www.ti.com/video/6287050244001) - the BQ27427 charger (https://www.digikey.com/en/products/detail/texas-instruments/BQ27427YZFR/17748369) is the latest to come out. It's very small, coming as a 9-pin 1.6x1.6 BGA with the center pad being a shared ground so you don't need plugged vias to use. It's also really easy to use, requiring only 2 small stabilization capacitors. Internal temperature monitoring means you don't need a separate thermistor. The high-side 7 mΩ current sense resistor also means one less part on the BOM. I2C pins are used to communicate with the monitor and set battery characteristics. There's also an optional input that can be used to connect to a mechanical or electrical battery insertion switch or to an external thermistor, and an optional output that can be used as a battery low indicator. Because so much is integrated, and the chip is so small, its very easy to pop it into your design between the battery terminal and the VBAT lines that go to your battery charger and power supply. The peak battery voltage and capacity are easy to look up since they're written on the battery. For other configuration settings you can use BQStudio / GaugeStudio (https://www.ti.com/tool/BQSTUDIO) with the TI battery devboard to characterize and customize the learning cycle. Either way, you will need to write the configuration to the sensor on every boot. Pick up the Texas Instruments BQ27427 (https://www.digikey.com/short/18pb1ftw) and other chips from the Impedance Track family (https://www.digikey.com/en/products/result?s=N4IgjCBcoLQCxVAYygMwIYBsDOBTANCAG4B2aWehA9lANrhwCsAnBALqEAOALlCCAF8hQA0) stocked at DigiKey for immediate shipment. Order today and you'll get precision lipoly monitoring that will work with any setup or battery configuration by tomorrow afternoon!

This week on the Great Search, we're taking apart a McDonalds McNugget Tetris game (https://tetris.wiki/Tetris_(McDonald%27s)) given away in China for the 40th anniversary of the chicken mcnugget. Unsurprisingly, it's an epoxy blob'd chip that does just about everything! For the background music, a disc piezo is used to make the beeps. We've covered magnetic buzzers before (https://blog.adafruit.com/2020/11/24/the-great-search-piezo-and-magnetic-buzzers-thegreatsearch-digikey-digikey-adafruit/) on the Great Search, which we use on some of our design for SMT tone-making. At a 500K build, budget is going to be the most important concern, so instead, we can go for a ultra low cost piezo disc! Let's take a look at what is available at DigiKey and the differences between magnetic and piezo buzzers. See the chosen part on DigiKey https://www.digikey.com/short/dtbmq7jm

Full tutorial: https://learn.adafruit.com/jellyfish-umbrella-with-easy-wled-wifi-control/ Make a jellyfish umbrella with animated lights, with no coding required. This is an intermediate project that gives you advanced results. The software is simple to load and use. Hundreds of animations and color combinations are available right through your fingertips, using any web browser or the free WLED app on your phone. The trickiest part of this tutorial is the wiring. There are a lot of connections to make and some challenging soldering to do, but the rest of the build is fairly easy. Make your jellyfish dance and flow with lights, tentacles, and iridescence. This project would make a great camp "totem" for festivals, or a wonderful costume if it's built onto an umbrella hat. It's also easy to synch two or more jellyfish together over wifi using WLED.

with most of our dev boards, sensors and feathers now sporting plug-and-play stemma QT ports (https://learn.adafruit.com/search?q=stemma%2520qt) it can be very fast to put together projects with half a dozen boards snapped together. But now you don't have a breadboard as a mechanical substrate... which is why jepler and scott collaborated on this nifty swirly grid design. originally 3D printed, we decided to upgrade these to an 'aluminum PCB' - note there's no actual copper on here, its just the aluminum backing, and then black soldermask with silkscreen. each square is 0.6 inch x 0.6 inch and there's holes every 0.2 inches. with the various dots and dashes you can pretty much make anything on a 0.1" grid fit. here's our demo to test it out. the aluminum is easy to cut/drill/machine/bend if you need more customization. coming soon to the adafruit shop!

this viral retro mini laptop just appeared on our desk, we ordered it about a month ago and its just as cute as you expect! with a modern TFT display and keyboard and USB disk interface, but still rockin the classic 8088 chipset (https://en.wikipedia.org/wiki/Intel_8088) - its a perfect experimentation platform for very old software. i love the reuse of these 90's datecoded chip. we got one of our old 512MB SD cards (https://www.adafruit.com/product/5252) to plug in for data transfer and have it running Spectrum Holobyte Tetris (https://www.myabandonware.com/game/tetris-dj). any recommendations of software we should try running? it won't be able to run doom - that requires a later chipset!

The Great Search - Single Channel 3V to 5V level shifter https://www.digikey.com/en/products/detail/diodes-incorporated/74AHCT1G126SE-7/2711993 On our new Prop-Maker Feather we like to do a 'favor' to our users by level shifting the NeoPixel signal from 3.3V to 5V. We don't always need this but some NeoPixel chipsets are a little finicky about the levels, especially if you have a 5.5V or 6V power line on the NeoPixels. We'll use a single buffer, and it needs to be small, so we'd like a tiny package. We'll also review the 74 series logic family (https://en.wikipedia.org/wiki/7400-series_integrated_circuits) to verify what series we want to filter out when we search on DigiKey for this part.

This week's EYE ON NPI passes the vibe check - it's Vybronics' Rectangular LRA Vibration Motor (https://www.digikey.com/en/product-highlight/v/vybronics/rectangular-lra-vibration-motor) and friends - a series of linear resonant actuators, AKA LRA, used to create vibration/haptic feedback. Haptics (https://en.wikipedia.org/wiki/Haptic_technology) were first used in airplanes - where originally there was a mechanical connection between the pilot controls and the plane steering. That is, when turning or tilting the yoke, it would mechanically control any flaps (https://en.wikipedia.org/wiki/Aircraft_flight_control_system). However, that means that the pilot would have to be strong enough to move the flaps while also keeping track of all the different controls needed - a recipe for disaster because a tired or confused pilot could make a catastrophic mistake! So, instead, the control of aircraft turned to hydro-mechanical and then servo-electrical. You might see the same on modern cars: instead of the steering wheel directly controlling the tire angle, it now send a signal that is interpreted by motors that do the actual movement, also known as Drive by wire. (https://en.wikipedia.org/wiki/Drive_by_wire) The trade-off with drive or fly-by-wire is that there's less need for strength and speed by the person in the cockpit - but they do lose the mechanical feedback that would normally be fed back through the mechanical linkages. That feedback is important because it allows you to feel when something might be blocking or fighting against the motion - in planes you can tell the airspeed and the craft's stress level. Sure you can put this information in a gauge of some sort but it requires the operator to look and interpret a number when the feeling is more intuitive. Thus the invention of force feedback or...haptics! Haptics have been tirelessly used in automotive and aircraft for decades, when in the 90's they had a bit of a resurgence as part of VR interfaces. If you're in a 3D rendered virtual world, you want to feel when you bumped into something or grabbed an item successfully. For gaming, an early form of 'play by wire' we've moved from the 1994 Aura Interactor (https://en.wikipedia.org/wiki/Aura_Interactor) to being included in almost every game controller, like the 1997-released N64 Rumble Pak (https://en.wikipedia.org/wiki/Rumble_Pak) and Playstation DualShock (https://en.wikipedia.org/wiki/DualShock) as vibrational feedback when moving or taking damage. Mobile devices are also big users of haptic feedback - originally as vibration alert for 'silent mode' - but now also for typing and UX feedback. For vibration feedback, a basic ERM motor such as the Vybronics VZ43FC1B5640007L (https://www.digikey.com/en/products/detail/vybronics-inc/VZ43FC1B5640007L/12323649) will do fine - turn it on to cause a vibration that can be detected even when the phone is in a bag or pocket. But if you want to have 'sharper' feedback, these ERMs aren't as good because they take time to turn on and get up to speed. So they're good for big motion but not quick motion. That's when you want to use LRAs - Linear Resonant Actuators. (https://www.digikey.com/en/product-highlight/v/vybronics/rectangular-lra-vibration-motor) Vybronics makes a wide range of LRA vibration motors (https://www.digikey.com/en/supplier-centers/jinlong-machinery) in addition to their wide range or ERM's. You can select from different sizes - larger ones will of course have a stronger feedback response, but will require more energy and size. ERM's are really easy to drive: provide a positive DC voltage and the motor starts moving. LRA's are harder to control, you will need an AC waveform to kick-start the resonant motion. (https://www.vybronics.com/lra-assembly-drawing) Our favorite driver is the TI DRV2605 (https://www.digikey.com/en/products/detail/texas-instruments/DRV2605LDGSR/5014144) which we even have a breakout board (https://www.digikey.com/en/products/detail/adafruit-industries-llc/2305/5356831) to make it easy to connect up to a Vybronics LRA. The DRV2605 even comes with a wide range of built-in waveform actions (https://www.ti.com/lit/ds/symlink/drv2605.pdf) to make integration very easy. Vybronics also has some examples of how to mount their motors with PCB contacts to allow the motor to vibrate within a cavity.(https://www.vybronics.com/mounting-with-spring-contacts) Vybronics' Rectangular LRA Vibration Motors such as the VLV152564W (https://www.digikey.com/en/products/detail/vybronics-inc/VLV152564W/19203005) will make the vibe right in your product that requires tactile haptic feedback to improve your user experience. With their small cases and high strength, they'll turn glass touchscreens and capacitive touch buttons into something that feels like a mechanical control surface.

This week's EYE ON NPI is enjoying the beautiful weather with you, whether sitting in the sun or lounging in the shade - all's good because we've got Nexperia's NEH2000BY Energy Harvesting Power Management IC with embedded solar MPPT capability! (https://www.digikey.com/en/product-highlight/n/nexperia/neh2000by-energy-harvesting-power-management-ic) This tiny, low-cost chip is a one-stop solution for extending the life of your product by making it powered by small solar cells. This chip is perfect for wearables or miniature sensor nodes, maybe with a LoRa radio, WiFi or Bluetooth Low Energy where space and pricing is important. For example, an asset tracker, traffic monitor, activity watch, or agricultural sensor network: stuff that is outside anyways so it'll be designed for outdoor use and have lots of sun exposure. We've covered other MPPT tracking solar harvesting chips (https://blog.adafruit.com/2021/04/23/eye-on-npi-max20361-tiny-single-multi-cell-solar-harvester-maximintegrated/), and the NEH2000BY has some advantages in size, cost and simplicity. Either use it to increase the time between charges, or use it to have your product be fully encased with no need for charging at all, thanks to the power of the SUN (https://solarsystem.nasa.gov/solar-system/sun/galleries/?page=0&per_page=25&order=created_at+desc&search=&href_query_params=category%3Dsolar-system_sun&button_class=big_more_button&tags=sun&condition_1=1%3Ais_in_resource_list&category=51) The Nexperia NEH2000BY energy harvester (https://www.digikey.com/short/hpnfttw3) is designed specifically for use with solar cells because cells collapse under high current draw - which is what batteries want when they are charging up so that they can be ready to go ASAP! When drawing current from a solar cell, at the very beginning the voltage is very high, then is slowly drops down as more is drawn until the input voltage collapses completely. So you have to be very careful when drawing current - too little and you lose out on efficiency, too much and your power goes away completely. There's a 'sweet spot' right in the middle, where you can get the most power output, which is called the Max Power Point. (https://en.wikipedia.org/wiki/Maximum_power_point_tracking) And this point varies with how much sunlight you get - so it isn't something you can pre-program in with a comparator or anything. Instead, the energy harvester has to wiggle the power draw forward and back to find the maximum point. For large-scale solar installations, you'd have a microcontroller do the math for you, and adjust throughout the day - it isn't hard to do MPPT it just takes measurement and computation. But in small and low-current situations, you can't spend all your power budget on a microcontroller to manage your battery charger. First up, almost no extra components are needed: just a stabilization capacitor plus a capacitor for the switched-cap boosting doubler. Note that there's no inductor because it seems to use a switched-cap boosting method for approximately 2x voltage output - so you will need to spec a panel that, when the MPPT voltage is approximately doubled, you'll have about 0.3V above the battery voltage. There's some math in the datasheet to work this out but basically in the end, use a panel with an open-circuit voltage - Voc - that is about 0.7 times the battery voltage. So, e.g. if you're using a Lipoly (https://www.digikey.com/short/h02tmj1q), with a VBat of 4.2V, use a 3V solar panel - which is very common and inexpensive. For NiMH cells, add up the total series voltage before multiplying by 0.7 for the Voc desired. To keep your battery from over-charging, either use a separate battery charger chip that will do the constant-current to voltage-limited charging, or use a low cost over-voltage protection (OVP) chip as recommended in the datasheet. If you'd like to integrate the Nexperia NEH2000BY Energy Harvesting Power Management IC (https://www.digikey.com/short/hpnfttw3) into your next solar-powered product, thank your lucky stars because DigiKey has the NEH2000BY in stock right now at a great price for immediate shipment. With the long summer days ahead, you can order today and be max-power-point'ing before the sun sets tomorrow.
