Our OPT4048 breakout is ready — now with a bonus web app! 🌈💻 2:13

לפני 23 ימים2:13

2:13

We're wrapping up the design for the OPT4048 breakout: mostly putting the finishing touches on the Arduino library (https://github.com/adafruit/Adafruit_OPT4048). Since the whole point of this sensor is that it gives you CIE X & Y coordinates, we thought it would be cool to plot that onto a CIE diagram (https://en.wikipedia.org/wiki/CIE_1931_color_space). Historically, we’d have to use Processing (https://processing.org/), but now you can use WebSerial to get data directly from a microcontroller! Only catch — it’s been like 15 years since I wrote JavaScript, so we asked Claude Code (https://docs.anthropic.com/en/docs/claude-code/overview) to help out. With a little direction, it delivered a perfect demo (https://github.com/adafruit/Adafruit_OPT4048/commits/gh-pages) in about 30 minutes. It was so fun, we’re thinking of doing WebSerial demos for more products! You can try it out by uploading the code here (https://github.com/adafruit/Adafruit_OPT4048/blob/main/examples/opt4048_webserial/opt4048_webserial.ino) and then visiting this page: https://adafruit.github.io/Adafruit_OPT4048/webserial/ #Arduino #WebSerial #ColorSensor Visit the Adafruit shop online - http://www.adafruit.com ----------------------------------------- LIVE CHAT IS HERE! http://adafru.it/discord Subscribe to Adafruit on YouTube: http://adafru.it/subscribe New tutorials on the Adafruit Learning System: http://learn.adafruit.com/ -----------------------------------------…

LED Butterfly Bench - Playa Tech with Edge-Lit Acrylic and Sparkle Motion 1:04

לפני 23 ימים1:04

1:04

Full tutorial: https://learn.adafruit.com/butterfly-bench-with-edge-lit-acrylic/overview Build a bench for your backyard or your festival theme camp that shows your logo or camp mascot in glowing rainbow colors. Playa Tech is a system of furniture plans designed by Sunshine Zwern. Create benches, tables and chairs from a single sheet of plywood using common wood shop tools. The furniture packs flat, then slots together in minutes, allowing you to bring an entire living room set for your festival camp in the back of your Subaru. This system is rapidly gaining popularity with the Burning Man crowd, and we've seen it being used at festivals nationwide. Our camp decided to get a bit fancy this year and worked together to create this Playa Tech Butterfly Bench. The butterfly is cut with a handheld CNC router from a sheet of 3/4" plywood, and then back-lit with edge-lit 1/4" acrylic, 30/m NeoPixels and running WLED software powered by a Sparkle Motion board. It's a lovely addition to our camp setup, and makes an absolutely lovely "selfie spot" in any garden. The LED build is pretty easy on this project. The challenge is in the woodworking. But, who doesn't love a good woodworking challenge?

Desk of Ladyada – Designing More Protos & Trying Out Codex 30:53

We're back to designing more prototypes to get the product pump primed! Having lots of boards to work with means we can reliably get one or two shipping each week. To that end, here are some upcoming chips we've made breakouts for: SLB9670VQ20FW785 (TPM chip): https://www.digikey.com/en/products/detail/infineon-technologies/SLB9670VQ20FW785XTMA1/11697680 INA237 (Power monitoring): https://www.digikey.com/en/products/detail/texas-instruments/INA237AIDGSR/14004323 INA238 (High-speed current/voltage sensor): https://www.digikey.com/en/products/detail/texas-instruments/INA238AQDGSRQ1/14641449 STSPIN220 (Stepper motor driver): https://www.digikey.com/en/products/detail/stmicroelectronics/STSPIN220/6137574 LM73100 (Hot-swap controller): https://www.digikey.com/short/hfnzpwjq SC16IS74x (UART to I²C/SPI bridge): https://www.digikey.com/en/products/detail/nxp-usa-inc/SC16IS740IPW-128/1301043 We also tested out Codex as an alternative to Claude for code generation. One benefit is the option to select specific models. We tried o3 (which struggled) and o4-mini (which did okay), but Claude still leads for now. Protos are pumping! We're designing breakouts for new chips + testing Codex vs Claude. Also: help us find a WM8960 replacement and maybe... should bring back the DIGG button kit?…

EYE on NPI – Sensirion SEN66 Environmental Sensor Node 8:59

לפני 29 ימים8:59

8:59

This week's EYE ON NPI features a new 'everything' sensor, the Sensirion SEN66 Environmental Sensor Node (https://www.digikey.com/en/product-highlight/s/sensirion/environmental-sensor-node-sen6x) . This is a highly-anticipated update to the SEN5x (https://www.digikey.com/en/videos/s/sensirion/eye-on-npi-sen54-environmental-sensor-node) goes hard on gas sensing, with VOC, NOx and CO2 sensors built in. You can even update to the SEN68 and get formaldehyde HCHO sensing! What we like about this series is the complete solution for all kinds of environmental sensing with a single cable. Sensirion is one of our fav sensor companies: from classics like the SHT45 (https://www.adafruit.com/product/5665) to the popular SGP30 (https://www.adafruit.com/product/3709) and the high quality SCD30 (https://www.adafruit.com/product/4867) we have made breakouts for many-a-sensor from this company. Lately they've started to do fully integrated products - like the SEN5x series (https://www.digikey.com/en/videos/s/sensirion/eye-on-npi-sen54-environmental-sensor-node) that we covered earlier on EYE ON NPI. The SEN54 series has particulate matter (PM1, PM2.5, PM4, PM10) dust sensing, plus temperature, humidity, volatile organic compounds (VOCs), with the SEN55 adding NOx. We saw this sensor often paired with an SCD30 (https://www.digikey.com/short/d1h3t1n4) or SCD4x (https://www.digikey.com/short/zmh2zjz3) to add CO2 sensing. Those folks will like the look of the SEN6x series as now we get CO2 sensing in all but the lowest-cost SEN60. One thing to note with CO2 sensing is that once a week it needs to 'self-calibrated' by letting it sense fresh outdoor air which will be ~400ppm. This isn't a bad idea for your health either. Another new sensor added in the upcoming SEN68 is formaldehyde, which integrates the SFA30 (https://www.digikey.com/short/2d5fb8rt). If you've used the SEN5x series, (https://www.digikey.com/en/videos/s/sensirion/eye-on-npi-sen54-environmental-sensor-node) you're probably familiar with their connection interface: a JST GH 6-pin cable is used to connect and provide power and I2C data connection. However, one thing to note is that the cable is the same but the pinout has changed. Power is now 3.3V instead of 5.0 and there's no UART interface, so the SEL pin is not available. For that reason, if you'd like to use the same cable, go for it - but the circuitry will need to change...for example we're revising our SEN5x breakout (https://www.digikey.com/short/h0jffnm2)! We like that, just as with the SEN5x series, the SEN6x (https://www.digikey.com/en/product-highlight/s/sensirion/environmental-sensor-node-sen6x) uses plain I2C to communicate. This makes it easy to integrate with any microcontroller or microcomputer, and the added CRC helps avoid accidental data corruption from EMI or loose cables. The interface is not just to each individual sensor - there's only one I2C address and command structure and once you initialize the sensor you can read all values at once for 'timestamped' consistency. The commands are easy to implement, but if you want a head-start, check out the Sensirion GitHub account (https://github.com/Sensirion?q=sen6&type=all&language=&sort=), they have code in C and Python for a 5-minute quick start. Excited to check this fancy new combo-sensor out? You're in luck because DigiKey has the Sensirion SEN66 Environmental Sensor Node (https://www.digikey.com/short/0d4jt424) in stock right now for immediate shipment! Order today and DigiKey will ship it you in an instant - you will be sensing up a storm by tomorrow afternoon!

The Great Search - 1 Amp +, Mid-Voltage (12V+) Ideal Diode for Solar Panels 10:27

לפני 5 weeks10:27

10:27

With sunny days ahead, we're working on more solar projects. One thing that comes up often is we need is a diode to keep the PV panel current only flowing into a charging circuit. Often times folks use a Schottky diode (https://www.digikey.com/short/b5d8495f) for their low forward voltage. But as you get to an Amp or more, you're still looking at a loss of 0.5V, or 0.5W and that number only goes up with higher currents! Thus the need for an 'ideal diode': we've already got a breakout for an ideal diode but it's only 5V max (https://www.adafruit.com/product/5830). Let's look for one that can handle higher voltages and at least an Amp of current.

The Great Search – Power Monitor with 2 Inputs 7:59

לפני 5 weeks7:59

7:59

For our solar-capable Feathers, we're going to design a FeatherWing helper board to assist with solar connection and monitoring. To do that, we will want to monitor two voltages (the LiPoly battery and the solar panel) and one current (the panel draw). Traditionally, we've liked using the INA219 and friends—let's see if we can find a voltage/current monitor chip with an I2C interface and at least two monitoring inputs.

EYE ON NPI - Panasonic's VL/ML Series Lithium Rechargeable Coin Batteries 10:35

לפני 5 weeks10:35

10:35

This week's EYE ON NPI is looking at itsy-bitsy-teensy-weensy little rechargeable batteries that can keep your micro-power electronics running for many years without needing any maintenance from your users: it's Panasonic's VL/ML Series Lithium Rechargeable Coin Batteries (https://www.digikey.com/en/product-highlight/p/panasonic/lithium-rechargeable-coin-batteries). These are small, solderable batteries much like the coin cell batteries you're used to replacing in watches, toys, and other gadgets..but this time they can be recharged in-circuit to make maintenance effortless. We've covered lots of batteries and battery holders on EYE ON NPI - from enormous lead acid batteries to tiny coin cells (https://www.digikey.com/en/products/filter/batteries-non-rechargeable-primary/). These are an essential part of the engineer's repertoire as so many products need to work when not plugged into the wall. We use coin cells a lot in our design work: there's nothing as compact and they have great energy density. But they're typically 'primary cells' - not rechargeable. That might be fine if you're using them for something like a remote control (https://support.apple.com/en-us/101261) or a small toy. But they do eventually need to be replaced, which can be a user frustration. For that reason, many products that used to have primary cells like AA's or coin batteries have slowly transitioned to embedding lithium polymer pouches. You can get rechargeable lipoly batteries in 100 mAh or less! (https://www.digikey.com/short/7njnd057) However, there may be some cases where you still want something really really tiny, like say 9mm diameter and under 1mm thick - a size only achievable with a coin cell - but without dealing with removing and replacing a battery every few weeks or months. Especially if we're talking about something that is going to be plugged in once in a while, or where the coin cell is a fall-back. This comes up often with devices that have real time clocks (RTCs) - such as clocks, computers, laptops, tablets, watches, GPS units (https://www.adafruit.com/product/5440), etc. They might have a main battery or power system that can run a microcontroller/CPU and display plus peripherals, but you still want to keep time and maybe an alarm setting when the main power cuts off. Historically, folks have just used coin batteries - ideally replaceable ones - but sometimes not as in the case of the DS1287 (https://theretroweb.com/chip/documentation/ds1287-647b3602989d3299594321.pdf) which had the coin battery sealed inside! If you're designing a product today that needs an RTC battery, we'd say take a good look at the Panasonic's VL/ML Series Lithium Rechargeable Coin Batteries (https://www.digikey.com/en/product-highlight/p/panasonic/lithium-rechargeable-coin-batteries). No holder required: they come with tabs to solder directly onto a PCB in vertical or horizontal orientations. And they come in a variety of sizes from the 20mm / 45mAh to 12mm / 7mAh and even smaller. Note that as expected, you're going to get less capacity than a primary cell, so these are good when you think you'll get recharged every few days or weeks. Don't forget: you will absolutely need a proper lithium charger to recharge these batteries. We've got plenty of charger breakouts you can use, we particularly like the bq25185 (https://www.digikey.com/en/products/detail/adafruit-industries-llc/6091/25805553) which you can easily configure for the 1C current charge rate to match your Panasonic Lithium Rechargeable Coin Batteries (https://www.digikey.com/en/product-highlight/p/panasonic/lithium-rechargeable-coin-batteries) They can all handle 1000+ cycles, we like the bq in particular because it has power-path which will help avoid unnecessary discharging/cycling. Ready for a tiny burst of power to keep your clocks a-tickin'? You can pick up a wide selection of Panasonic's VL/ML Series Lithium Rechargeable Coin Batteries (https://www.digikey.com/en/product-highlight/p/panasonic/lithium-rechargeable-coin-batteries) at DigiKey right now! They're in stock in a range of sizes and configurations for immediate shipment - don't forget that like all Lithium batteries you may need to ship ground, so order now and you'll get those bite-sized batteries shipped within the hour for immediate integration.

Over the holiday break, we designed a few Sparkle Motion (https://www.adafruit.com/search?q=sparkle+motion) ESP32 boards for use with WLED. They’ve been working well, so we decided to finish up the third version we cooked up—a USB “stick” for quick builds that you can power from a wall adapter, computer, or even a USB battery pack for portability. We managed to fit in a fuse, an I²S microphone, infrared-remote input, a mode-select button, two level-shifted outputs, and terminal blocks. It’s designed to fit inside a pre-made snap-fit case (https://www.adafruit.com/product/6176).

EYE ON NPI - Bulgin's Battery Holders for Diverse Applications 7:45

לפני 6 weeks7:45

7:45

This week's EYE ON NPI is for those who need easy-to-maintain battery power for quick field maintenance - it's Bulgin's Battery Holders for Diverse Applications (https://www.digikey.com/en/product-highlight/b/bulgin/battery-holders-for-diverse-applications) a variety of battery enclosures and fixtures that will give your customers easy access to replace batteries no matter what size and configuration! If your product is going to be portable, or if you want battery back-up for timekeeping/configuration/sleep-modes, then you're going to need primary or secondary battery cells built into the design. Secondary cells (https://www.digikey.com/en/products/filter/batteries-rechargeable-secondary/91) are fairly popular these days: those are rechargeable batteries like Li-Poly packs. These are lightweight and high energy-density, which is why you see them everywhere from EV cars (https://www.digikey.com/en/blog/safety-first-approach-to-ev-and-battery-storage) to your Bluetooth earbuds. But they are not very user-friendly to replace, and if damaged can cause fires. They're also more challenging to ship by air due to restrictions on declarations and packaging of bare and with-equipment lithium cells. (https://www.ups.com/us/en/support/shipping-support/shipping-special-care-regulated-items/hazardous-materials-guide/how-to-ship-batteries) and for some field-use devices that may be used for long periods without being near a power outlet, being able to carry extra cells, for quick replacement, is a boon. For those reasons, there's still lots of products that run on your standard-issue primary batteries (https://digikey.com/en/products/filter/batteries-non-rechargeable-primary/90) a.k.a. 1.5V AAA, AA, C, D and 9V batteries. Of course, these days lots of people also use rechargeable NiMH in the same package: they are lower voltage, only 1.3V instead of 1.5V nominal, and have about 30% less energy but can be recharged safely/externally very easily. You can buy them at any corner store anywhere in the world for a few dollars and they have low self-discharge rates so they can be stored for many years. If you decide to go with standard-size batteries, you'll also need a way to hold them securely inside an enclosure. We like the look of these Bulgin battery holders (https://www.digikey.com/en/product-highlight/b/bulgin/battery-holders-for-diverse-applications) particularly the ones that mount to an enclosure wall and allow replacement without requiring a battery door that is custom molded. There's even options for IP67 hand-removable/replaceable covers for excellent waterproof-ness even in harsh environments while not sacrificing user-friendliness. On the inside of the enclosure you have solder lugs for easy attachment to your PCB by solder or spade connects. For many of the battery holders, a simple round drilled or punched hole is all that is needed. For your next battery-powered designs, take a look at Bulgin battery holders (https://www.digikey.com/en/product-highlight/b/bulgin/battery-holders-for-diverse-applications) - DigiKey has dozens of options in stock for immediate shipment. Order today and you'll get any of the Bulgin varieties shipped immediately so you can power your prototype by tomorrow afternoon!…
