It’s the very first episode of The Big Pitch with Jimmy Carr and our first guest is Phil Wang! And Phil’s subgenre is…This Place is Evil. We’re talking psychological torture, we’re talking gory death scenes, we’re talking Lorraine Kelly?! The Big Pitch with Jimmy Carr is a brand new comedy podcast where each week a different celebrity guest pitches an idea for a film based on one of the SUPER niche sub-genres on Netflix. From ‘Steamy Crime Movies from the 1970s’ to ‘Australian Dysfunctional Family Comedies Starring A Strong Female Lead’, our celebrity guests will pitch their wacky plot, their dream cast, the marketing stunts, and everything in between. By the end of every episode, Jimmy Carr, Comedian by night / “Netflix Executive” by day, will decide whether the pitch is greenlit or condemned to development hell! Listen on all podcast platforms and watch on the Netflix Is A Joke YouTube Channel . The Big Pitch is a co-production by Netflix and BBC Studios Audio. Jimmy Carr is an award-winning stand-up comedian and writer, touring his brand-new show JIMMY CARR: LAUGHS FUNNY throughout the USA from May to November this year, as well as across the UK and Europe, before hitting Australia and New Zealand in early 2026. All info and tickets for the tour are available at JIMMYCARR.COM Production Coordinator: Becky Carewe-Jeffries Production Manager: Mabel Finnegan-Wright Editor: Stuart Reid Producer: Pete Strauss Executive Producer: Richard Morris Executive Producers for Netflix: Kathryn Huyghue, Erica Brady, and David Markowitz Set Design: Helen Coyston Studios: Tower Bridge Studios Make Up: Samantha Coughlan Cameras: Daniel Spencer Sound: Charlie Emery Branding: Tim Lane Photography: James Hole…

EYE ON NPI - Texas Instruments SimpleLink Wi-Fi CC33xx Family 12:24

14 hours پیش12:24

12:24

This week's EYE ON NPI is a super connector - it's the Texas Instruments SimpleLink Wi-Fi CC33xx Family (https://www.digikey.com/en/product-highlight/t/texas-instruments/simplelink-wi-fi-cc33xx-family) with 2.4GHz and 5GHz WiFi 6 support, plus optional Bluetooth LE, in a low cost co-processor you can add to any microcontroller project you have to instantly IoT-ify it. This family of chips is a big upgrade in the CC3 family, and looks like a very competitive solution to existing market chips - we're excited to see how TI has adapted to the existing market to bring this compelling offering. Oh the TI CC3x series, how you've grown! We first met you back when it was the CC3000, a radical WiFi co-processor with the (at-the-time) astonishing price of ~$10 per module. At the time, we crafted an Arduino-compatible shield and a breakout board (https://learn.adafruit.com/adafruit-cc3000-wifi/overview) as well as an Arduino port of the TCP/IP mini-stack so that folks could do amazing things like get the time (https://learn.adafruit.com/adafruit-cc3000-wifi/internettime), read a web page (https://learn.adafruit.com/adafruit-cc3000-wifi/webclient) or even send a Tweet (https://learn.adafruit.com/adafruit-cc3000-wifi/sendtweet). The big thing was making it so you weren't spending the $50 it cost up-till-then to add a full-linux-system-as-peripheral (https://www.adafruit.com/product/1498). Since then, TI has released some updated versions, such as the CC3100 (https://www.digikey.com/short/9cp431pr), which added 802.11n and lower power draw - we saw it featured in a few micropython projects (https://blog.adafruit.com/2016/08/24/micropython-name-badge-from-emf-2016/) thanks to the core driver support (https://github.com/micropython/micropython/tree/master/drivers/cc3100). And after that, the CC3200 series (https://www.digikey.com/short/9289jcq3), which added TLS/SSL support and had an internal ARM Cortex-M4 that could run code on its own, like MicroPython! (https://github.com/micropython/micropython/blob/master/ports/cc3200/README.md) So it's no surprise that TI is continuing to press their WiFi family forward, to now the CC33xx! The new Texas Instruments SimpleLink Wi-Fi CC33xx Family (https://www.digikey.com/en/product-highlight/t/texas-instruments/simplelink-wi-fi-cc33xx-family) comes with 4 variants: the CC330x have 2.4GHz WiFi only, where-as the CC335x add 5GHz for an additional cost. Likewise, the CC33x0 have only WiFi, and the CC33x1 have WiFi+BLE. Since all the chips / modules are pin-compatible, you can develop with one and then change in production to whatever final setup suits your product. Like the earlier chips, these chips are expected to be connected to a main processor: either a microcontroller or microcomputer, over SPI or SDIO. SPI will work great for your smaller micros, SDIO is great when you have the speed and bandwidth to shift a lot more data around. When connecting over BLE, use the UART-with-flow control - that's the standard for a "BTLE Host Controller Interface" communications (https://www.bluetooth.com/wp-content/uploads/Files/Specification/HTML/Core-60/out/en/host-controller-interface/uart-transport-layer.html). Of course, there's no way you'll want to write a driver for this kind of complex chip - so visit the CC33xx software download page (https://www.ti.com/tool/CC33XX-SOFTWARE) which has software in the form of Linux kernel patch/drivers for beefy chips, or an microcontroller with an RTOS - follow their porting guide to get it running on a non-TI chipset (https://dev.ti.com/tirex/explore/node?node=A__AEIJm0rwIeU.2P1OBWwlaA__CC33XX-RTOS-MCU__dzPVh4K__LATEST) Now you're probably saying "OK cool but I don't want to do a bunch of RF layout, I want a nice tinned module i can slap down and connect my RP-SMA or chip antenna" - and not surprisingly, it looks like there's a CC3301 module (https://www.ti.com/product/CC3301MOD) in pre-production with an optimistic budgetary price of $2.88 - that's for 2.4GHz + BLE. For the 5GHz CC3351MOD (https://www.ti.com/product/CC3351MOD) the price is $3.50. Sans BLE the CC3350MOD (https://www.ti.com/product/CC3350MOD) is $3.13. If you want a peek at what the CC3301 module might look like, the BoosterPack product page has a tantalizing glimpse (https://www.ti.com/tool/BP-CC3301MOD). You can sign up at TI's site for updates on the release schedule, or chat with your DigiKey sales rep and they'll let you know when the part makes it into general distribution. Until then, you can get plenty of TI CC3350 (https://www.digikey.com/short/3z7tqtrp) and CC3351 (https://www.digikey.com/short/hmqzwv5j) bare chips: they're both in stock at DigiKey for immediate shipment! Order today and you'll quickly add low-cost WiFi 6 + BLE support to your next design, with 2.4/5 GHz support so you're ready for any customer or configuration. With ready-to-go software, and great low prices, you can get your design set up with cutting-edge networking without breaking the BOM bank.…

The Great Search – UV LEDs for Costuming 10:23

۵ روز پیش10:23

10:23

We recently got a request to make LED sequins with bright UV LEDs for costuming projects using UV-reactive paints and textiles. Also known as 'blacklight' paint or fabric, these dyes glow fluorescent when exposed to UV light. 🔗 https://www.digikey.com/short/bndtdnbr 🔗 https://www.adafruit.com/search?q=led+sequin 🔗 https://en.wikipedia.org/wiki/Ultraviolet However, not all UV LEDs will work! UV ranges from 100nm to 450nm, and some frequencies are used for curing or disinfection. For light effects, 365nm is the 'peak' frequency to look for. Let’s find a ~365nm SMT UV LED we can pick and place onto a small PCB for easy sewing. ✨🧵 ----------------------------------------- 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/ ----------------------------------------- #ElectronicsDesign #UVLED #TheGreatSearch…

EYE ON NPI – onsemi NIV3071 4-Channel eFuse Solution 7:58

۹ روز پیش7:58

7:58

This week's EYE ON NPI is another onsemi device - this week we're looking at the NIV3071 4-Channel eFuse Solution (https://www.digikey.com/en/product-highlight/o/on-semi/niv3071-4-channel-efuse-solution) a power distribution manager that can lets you manage a product with a lot of power domains and supplies using just a couple GPIO pins. This week's product is an upgrade from the covered-earlier NIS5420 (https://blog.adafruit.com/2021/09/09/eye-on-npi-onsemi-efuse-porfolio-eyeonnpi-digikey-onsemi-digikey-adafruit/) - with a higher 8~60V input range, and 4 independently-controlled channels. When people first meet fuses, they usually see and think of classic 'wire' fuses (https://www.digikey.com/en/products/detail/bel-fuse-inc/5ST-200-R/1009012) with ceramic or glass or thermoplastic bodies, and a thin wire inside. When too much current goes through the fuse wire, it gets hotter and hotter and eventually melts, cutting off the load from the source voltage. These kinds of fuses are super cheap, very-very-low resistance, easy to find at any hardware store, and there's lots of suppliers with various current limits. However, they're one-shot usage only and only good for over-current, can't act as switches/sequencers. You need to have a way for customers to access the fuse in order to replace it. For those reasons, a lot of engineers prefer going with 'poly fuses' - fuses that are easy to mount into a circuit that auto-reset after a time (usually minutes) so that a temporary overload doesn't make the device a brick so quickly. For example, we have a chunky 24V 5A hold / 10 A trip polyfuse (https://www.digikey.com/en/products/detail/littelfuse-inc/2016L260-24MR/6347052) on the Sparkle Motion board design (https://www.adafruit.com/product/6100), designed to protect folks who accidentally have a short in the output LED strings, and want to avoid damaging the power supply or main board. Poly-fuses are a great step-up from plain wire fuses: they're fairly inexpensive, available from lots of suppliers with various current limits, and best of all the fuse auto-resets after cooling down. However, like wire fuses, they're good for over-current, can't be reset, and have some variation depending on ambient temperature: you may trip 50% higher if its cold, or lower if its hot. Thus the next generation of fuses: eFuses (https://www.digikey.com/en/product-highlight/o/on-semi/efuse-automotive-circuit-protection)! As you could imagine, these are pure-silicon fuses, with a chunky N-FET that acts as the cut-off switch, and current limiting managed as an analog feedback loop that will cut the FET when too high. We get the resetability of a polyfuse, with additional control like sequence-able enable pins and under-voltage lockout. Note that some eFuses also can do over-voltage clamps and negative voltage protection, but the NIV3071 (https://www.digikey.com/short/3v0thr1p) doesn't contain these protections, so you may want to implement those protections separately. Especially designed for automotive power systems, which tend to be 12V/24V/36V/48V multiples, the NIV3071 (https://www.digikey.com/short/3v0thr1p) is AEC−Q100 qualified and PPAP capable (https://www.onsemi.com/pub/collateral/tnd6284-d.pdf). The use of eFuses is becoming popular as cars have become more computerized and electrified, with each 'zone' in a car (https://www.onsemi.com/solutions/automotive/zonal-architecture) - such as entertainment, communication, lighting, charging and sensors - all needing separate power management. If you don't need automotive qualifications, the functionally-compatible NIS3071 (https://www.digikey.com/short/9v2dmvhf) is a couple of cents cheaper. This family of eFuses is good for up to 60V and 2.5A per channel, but if you need more per channel you can just double or triple them up to add 2.5A per. If you want less per channel, to protect low-power devices from overheating or accidental shorts, the current limit can be reduced with an external resistor. And of course, you can turn on/off each channel with a GPIO enable pin: great for sequencing your power chain to reduce stress on the power supply from inrush current, or to allow each section to stabilize and go through self-test. For your next power supply design, the onsemi NIV3071 (https://www.digikey.com/short/3v0thr1p) and NIS3071 (https://www.digikey.com/short/9v2dmvhf) offer high-voltage, high-current control in a small package and a great price. Both are in stock right now at DigiKey for immediate shipment, so you can book today and start integration by tomorrow afternoon.…

The Great Search – 4.7 µH RF Inductor Q greater than 20 at 25 MHz 9:53

12 روز پیش9:53

9:53

For our SI4732 radio breakout, we're following the application note (https://www.skyworksinc.com/-/media/Skyworks/SL/documents/public/application-notes/AN383.pdf) for antenna setup. It specifies a low-pass filter inductor of 4.7 µH with a Q factor greater than 20 at 25 MHz and minimal DC resistance. The recommended part, COILCRAFT 1008CS-472GLB (https://www.digikey.com/en/products/detail/coilcraft/1008CS-472XGRC/15794541), is somewhat pricey. Let's explore some alternatives! Recommended Alternatives: Murata LQW2UAS4R7J00L: 4.7 µH, Q=20 @25 MHz, 260 mA, 4 Ω DCR, 1008 package. Abracon AISC-1008-4R7J-T: 4.7 µH, Q=20 @25 MHz, 260 mA, 4 Ω DCR, 1008 package.

Trying out Claude Code with Sonnet 4 for our STSPIN220 library 🌀🤖🔧 3:31

14 روز پیش3:31

3:31

We got the drop that Sonnet 4 (https://www.anthropic.com/news/claude-4) just got released and the baby went to sleep early, so let's try it out! We wrote a library for the STSPIN220 (https://www.digikey.com/en/products/detail/stmicroelectronics/STSPIN220/6137574) — this is a stepper motor driver like the A4988 (https://www.adafruit.com/product/6109) or TMC2209 (https://www.adafruit.com/product/6121), but for low voltage motors. One interesting thing about it is it uses the step/dir and two mode pins to set the micro-steps, from 1 to 1/256. Since that gets a little confusing, we figured a driver (https://github.com/adafruit/Adafruit_STSPIN) would be worth doing. The table was definitely annoying to decode, and higher microsteps started overflowing 16-bit variables, but now we've got it spinning happily! #anthropic #claude #sonnet 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/ -----------------------------------------…

EYE ON NPI - onsemi ARX383CS 1/8-inch 0.3 Mp Global Shutter CMOS Digital Image Sensor 8:07

16 روز پیش8:07

8:07

This week's EYE ON NPI is renowned world-wide, it's onsemi's ARX383CS 1/8-inch 0.3 Mp Global Shutter CMOS Digital Image Sensor (https://www.digikey.com/short/45p5vfvr), a tiny pick-and-placeable vision sensor that is perfect for your next AI or robotics - or AI robotics - product! With the global shutter, you'll be able to get clear and complete photos each time, no matter your lighting and subject speed. We stock low-cost simple camera sensors like the OV5640 at the Adafruit shop (https://www.adafruit.com/product/5839) these cameras can do color, up to 720p or greater, and can even do internal JPEG compression before piping the image out of an 8-bit parallel interface. One thing that you'll quickly realized about these cameras is that they, like almost all cameras used for basic photography are rolling-shutter type. (https://en.wikipedia.org/wiki/Rolling_shutter) That means the sensor reads each individual pixel in a row before moving to the next column, perfectly fine as long as the thing you're photographing is moving slowly compared to the speed of the sensor iterator. For robotics vision projects, this often gives smeared or blurry images, and since time = money and thus you need to run the motor as fast as possible. For example, our SM481 pick and place (https://www.hanwha-pm.com/en-mo/product/detail.asp?product_info_id=189&cate_id=50) can do up to 40,000 components per hour, each one with vision inspection: that's 10 a second! Whether you are building the fastest Rubik's-cube solver (https://www.youtube.com/watch?v=59qgzzSD1tk) or a license plate reader (https://www.digikey.com/short/45p5vfvr) getting crisp-clear full-frame images is essential to make sure you get the best image. The ARX383CS (https://www.digikey.com/short/45p5vfvr) is sold as a chip-scale-package, meant for pick and placing directly onto a PCB or FPC. It'll need various power supplies and clock signal, as well as configuration over I2C and of course a lens and lighting. Once set up, images can be captured and sent over DSI/MIPI single-lane, at VGA 640x480 up to 120 FPS or quarter-VGA 320x240 up to 245 FPS. The available datasheet doesn't have all the details, you'll need to contact onsemi to sign an NDA for the full specifications. onsemi has also developed a read-to-go plug-in camera module that you can quickly integrate called the PRISM1M-ARX383CSSM130110-GEVB (https://www.onsemi.com/design/evaluation-board/PRISM1M-ARX383CSSM130110-GEVB) which is not in stock right now at DigiKey yet (https://www.digikey.com/short/zfm5d7tj) but we're sure that if you need it you can try contacting DigiKey's sales reps and they'll be able to get you samples and quantity pricing. If you don't mind a bulkier eval board, the ARX383CSSM28SMKAH3-GEVB (https://www.digikey.com/short/78p2c3dq) is available immediately for purchase. If you've needed to add fast video or photography to your next product, the onsemi ARX383CS 1/8-inch 0.3 Mp Global Shutter CMOS Digital Image Sensor (https://www.digikey.com/short/45p5vfvr) is an excellent way to add a VGA global-shutter sensor with 125 FPS VGA-resolution output and I2C control. Best of all DigiKey has tons in stock for immediate shipment, book today and they'll send you as many as you want in the blink of an eye so you can start getting high speed video integrated by tomorrow afternoon.

EYE ON NPI - TI BQ25798 I2C Controlled, 1 to 4-Cell, 5-A Buck-Boost Battery Charger for Solar Panels 11:37

This week's EYE ON NPI is a follow up to one we did a few years ago on the similarly-named BQ25792 (https://blog.adafruit.com/2021/05/06/eye-on-npi-ti-bq25792-i2c-controlled-1-4-cell-5a-buck-boost-battery-charger-eyeonnpi-adafruit-digikey-adafruit-digikey-txinstruments/). The BQ25798 (https://www.digikey.com/short/vnr279pz) builds on the '92 by adding selectable dual inputs and true MPPT solar support. This chip is inexpensive, powerful and can handle almost any battery and power source matching you desire. Let’s look at some specifications: High power density, high integration buck-boost charger for 1-4 cell batteries supporting USB PD 3.0 profile – Integrates four switching MOSFETs, BATFET – Integrates input and charging current sensing Highly efficient – 750-kHz or 1.5-MHz switching frequencies – 5-A charging current with 10-mA resolution 96.5% efficient: 16-V battery at 3A from 20V Supports a wide range of input sources Autonomously sampled open circuit voltage (VOC) maximum power point tracking (MPPT) for charging from a photovoltaic panel – 3.6-V to 24-V wide input operating voltage range with 30-V absolute maximum rating – Detects USB BC1.2, HVDCP and non-standard adapters Dual-input power mux controller (optional) Narrow voltage DC (NVDC) power path Backup Mode with Ultra-fast switchover to adjustable voltage Powers USB port from battery (USB OTG) – 2.8-V to 22-V OTG output voltage with 10-mV resolution to support USB-PD PPS – OTG output current regulation up to 3.32 A with 40-mA resolution Flexible autonomous and I2C mode for optimal system performance Integrated 16-bit ADC for voltage, current, and temperature monitoring Like the '92, the BQ25798 (https://www.digikey.com/short/vnr279pz) supports any size battery. We have lots of battery packs in the Adafruit shop, and in particular we use 1S batteries – if there are more batteries, they are wired in series. But there’s lot of folks who are building robotics that require higher voltages, so they have 2S, 3S, or 4S batteries. This charger can handle any of ’em, and you can configure the battery pack size using a simple resistor on the PROG port. In this case it also allows the chip to run in 'standalone' mode without the use of I2C to configure. The biggest improvement you get with the BQ25798 (https://www.digikey.com/short/vnr279pz) is true solar MPPT support. The BQ25792 had VINDPM and IINDPM – the ability to track the input voltage to make sure it is not drooping from overdraw. While this lets you get pretty-close-to-MPPT it isn't true power-point-tracking which requires perturbation around the voltage to adjust as light and temperature affect the solar panel's efficiency. The '98 does this 'right' and even has a K Factor adjustment register - you can tweak this to get the best results based on different weather/temperature (https://www.ti.com/video/6287049638001)- or stick to the default value for good results. Another new feature is 'selectable dual-inputs' what this means if you can set up two power inputs - say DC plug and Solar - and then have the chip switch between them. This is particularly useful because you can't just use two OR'ing diodes to select the power source: the solar panel might have a higher initial open-voltage but can't supply as much current as a DC plug. I2C lets you select which one is priority! The BQ25798 (https://www.digikey.com/short/vnr279pz) also has many of the cool features we liked in the BQ25792: On-The-Go mode where you can turn the buck-boost around and have it generate a variable voltage output, say 5V for powering other USB devices. Another thing that works is powering over USB where you can have the BQ negotiate 'high voltage' support from USB 3 ports. Note that this isn't USB Type C power negotiation, for that you'll want to get a separate USB Type C PD negotiation chip like the TPS25750D (https://www.tij.co.jp/jp/lit/ml/slpp103/slpp103.pdf)...we're hoping there's a future version with PD built in! There's also a built in 16-bit ADC that you can use to monitor various voltages and current draw. While you can charge the battery in 'standalone' mode - you really do need I2C to get the best performance and capabilities. Thankfully there's not a huge number of registers, and SDA/SCL can be 3 or 5V logic signals so you should be able to get it working on anything from an ATmega328 to a Raspberry Pi. We like the high integration: you really only need a few passives and an inductor to get a fantastic all-in-one charger for any lithium ion battery pack. If you're intrigued and would like more information, you've come to the right place! DigiKey has the BQ25798 (https://www.digikey.com/short/vnr279pz) in stock right now for immediate shipment. Order today and you can start designing your solar-powered products of the future by tomorrow afternoon.…
