The Allwinner F1Cx00S series of chips are famous for being "$2 linux-on-a-chip" with DRAM built in - all you need is some passives, a crystal, and SPI NOR flash memory to have a miniature booting linux board. It's not very fast, and it's not very powerful but maybe we could run minimal python scripts on it? we've never used this chip but we used to noodle with openwrt and this seems kinda similar. we couldn't find any open hardware designs so we're drafting up the schematic - hopefully get all the wiring for this 88 pin QFN right :) anyone use this chip before? #adafruit #linux #feather Visit the Adafruit shop online - http://www.adafruit.com ----------------------------------------- LIVE CHAT IS HERE! http://adafru.it/discord Adafruit on Instagram: https://www.instagram.com/adafruit Subscribe to Adafruit on YouTube: http://adafru.it/subscribe New tutorials on the Adafruit Learning System: http://learn.adafruit.com/ -----------------------------------------

The non-TFT version of the ESP32-S2 Feather has been out of stock for a few weeks because we made a design error in rev B and want to fix it before putting back in the shop. We used a P-Channel FET to enable/disable the Stemma QT / I2C power but kept the pullups connected to 3.3V (this was on purpose because the onboard LC709 battery monitor is powered from the battery and this would let you read the battery state without having to enable the I2C power). when a bunch of QT sensors get attached, the leakage from the pullups turns into quite a power sink. for example, here we have 4 I2C devices on the bus and you can see the 'deep sleep' current is a whoppin' 700uA! no good...by switching to a separate regulator and connecting the pullups to the regulator output we get a cool 70uA as we expect. now we can send off this pcb to get this popular feather restocked - sign up at https://www.adafruit.com/product/5000 to get notified! #adafruit #feather #esp32 Visit the Adafruit shop online - http://www.adafruit.com ----------------------------------------- LIVE CHAT IS HERE! http://adafru.it/discord Adafruit on Instagram: https://www.instagram.com/adafruit Subscribe to Adafruit on YouTube: http://adafru.it/subscribe New tutorials on the Adafruit Learning System: http://learn.adafruit.com/ -----------------------------------------

Build a sketch drawing toy using CircuitPython and 3D Printing! Use the Feather M4 and 2.4in TFT FeatherWing to make a portable sketch drawing hand held device. Use knobs to move the cursor and flip the toggle switch to pen up or down and use the button to clear the display. This uses Display IO in CircuitPython to draw pixels on the TFT display.

For our Atari Video Music machine mod, we want to add an S-Video output port. S-Video splits the signal from NTSC into chroma and luma, so the signal tends to be clearer and more stable. Thankfully, the chip in the AVM gives us the chroma and luma on separated pins, so we just have to wire them up to a standard S-Video connector. Let's see how we can find one that will perfectly fit on the AVM without any drilling or gluing!

Washington Square Park - Sunday, February 27, 2022 🇺🇸 🇺🇦

We had been working on a lot of camera support for CircuitPython. We're getting back to that project now with an all-in-one DIY camera board with an OV5640 camera module and an ESP32-S2. You really do want PSRAM to buffer large images like 1440p JPEGs for saving to disk. One thing that we bumped into is that SD cards can be very finicky when initialized into SPI mode on a shared bus, but we found a way around it!

jepler ended the week on a high note, getting the motor of an Apple ][ floppy drive moving back and forth with CircuitPython! It's part of our quest to make Adafruit_Floppy work with non-PC floppy disk drives. The simple code making this happen can be found in a GitHub gist: https://gist.github.com/jepler/16cdb13d8c3298c392d789772a56d177 For this step, +5 and +12V supplies are required, coming from an ATX power supply. The reading circuit requires an additional -12V supply just to spice things up. After that, we'll see what else is needed to start reading and writing flux in these drives.

This week's search is going to be for an LCD driver chip. We've never actually worked with raw LCD elements, but if you do need to use one, you'll quickly note that they're a bit odd to work with and require an 'AC'-like waveform and constant refreshing. They're also very susceptible to ghosting. So let's identify a chip - ideally SPI or I2C - that will do all that drive control for us!

This week we worked on some upcoming new products, including the Feather ESP32 V2 which we listed in the shop in prep for stocking next week. it's a full refresh of the Feather ESP32 and we even got low power in deep sleep - down to 70uA! we also got some LCD samples in the post and had a fun time learning how to drive these with GPIO pins on a microcontroller. finally, foamyguy threw together a little project to make a pyportal into a little audio player and we'll check that out. i've been meaning to redesign the pyportal with an esp32-s3 and this project is sort of inspiring me to get on with it.

when we have a brand new board, we do a lot of checks to make sure that the first panel is right because if there's one thing that makes mistakes very quickly - its a mis-programmed pick and place! this is the time to check the right part, orientation and any placement offsets that need correction. this panel looks good and after it goes through the oven we'll do a first-article inspection with the tester before we let'er rip! this board is the new Feather ESP32 V2 which is a big update to our classic Feather ESP32 but with Stemma QT, NeoPixel, extra button, and a lot more FLASH and PSRAM. we think it'll be really popular! #adafruit #esp32 #feather Visit the Adafruit shop online - http://www.adafruit.com ----------------------------------------- LIVE CHAT IS HERE! http://adafru.it/discord Adafruit on Instagram: https://www.instagram.com/adafruit Subscribe to Adafruit on YouTube: http://adafru.it/subscribe New tutorials on the Adafruit Learning System: http://learn.adafruit.com/ -----------------------------------------

This week's EYE ON NPI is gonna spin you right round, baby, right round like a record player - it's C&K's ENC Series Optical Rotary Encoder Switches (https://www.digikey.com/en/product-highlight/c/ck-components/enc-series-encoder-switches) a high-reliability encoder with strong detents, that's great for medical and industrial equipment, automotive, and more, where longevity and reliability is important. Rotary encoders (https://www.digikey.com/en/products/filter/encoders/507) are a popular user interface element that engineers use to add a tactile increment/decrement control. We find they're much more intuitive to use than touch screens, especially when you want to increase or decrease a value precisely: its a lot easier to twist the knob by one detent than it is to press a touch screen once. Rotary encoders can also be used hands-free or when observing some output because the tactile feedback is strong. (https://www.digikey.com/en/articles/a-designers-guide-to-encoders) The most common rotary encoders used for user input are mechanical style, usually with detents. They can be ring-style like the famous iPod Clickwheel (https://support.apple.com/en-us/HT204217) or knob style. These are two mechanical rotary encoders in that there is a little leaf spring connected to the knob and the "common" pin, and the body has a metal-cutout piece, that when rotated connects and disconnects the two side pins from the common. The two pins pulse high and low to indicate motion and direction. Usually two interrupt pins are connected to the rotary encoder to catch the pulses and track the counter increment or decrement. Super fun and easy right? Except....that little leaf spring contact ends up rubbing against the gray code wheel and even good quality springs have a contact life of maybe 500,000 contacts. that's only 10,000 full turns - each turn is 2 x 24 contacts. if you're turning the knob 10 times a day the encoder will fail after 1000 days, about three years. And rotary encoders do fail, a lot! Heck, even our favorite scope we got right out of school has a broken encoder on the channel 1 zoom select (not surprising, since channel one is the most used and its turned constantly to zoom into the signal). A bad encoder may not be user-serviceable at all, and requires some care to desolder and replace - unless it's on a detachable cable or module, it can be a very serious repair. Flaky encoders are also a little dangerous - they can increment instead of decrement, which can be confusing and cause incorrect settings. If you're designing a medical device or a car where there's a knob that will be used daily, having it fail after 3 to 5 years is not going to be an option - especially since the failure can happen instantly. Not a good look when a $2000 product is taken down by a $2 encoder failure. Enter the optical encoder! Optical encoders solve the contact rating issue by replacing the leaf spring with two LEDs and an optical sensor. Instead of mechanically contacting the two grey code bits, the optical sensor provides the pulses without the risk of wear and tear. These cost a few dollars more than your everyday mechanical encoder but give you rock solid reliability. These C&K ENC optical encoders (https://www.digikey.com/en/product-highlight/c/ck-components/enc-series-encoder-switches) look and feel just like mechanical encoders. With 24 detents, they're a drop-in replacement. You can panel mount, and there's even a quick-replace connector with JST SH 6-pin socket (https://www.digikey.com/en/products/detail/jst-sales-america-inc/A06SR06SR30K51A/6009375), for easy replacement in the field. The C+K ENC Series Optical Rotary Encoder Switches (https://www.digikey.com/short/pw8p3tf8) are in stock right now for immediate shipment from Digi-Key! Order today and you'll be reliably twistin' and turnin' by tomorrow afternoon - don't forget to pick up some JST SH cables as well (https://www.digikey.com/en/products/detail/jst-sales-america-inc/A06SR06SR30K51A/6009375)!

This is a fingertip-sized 7-segment display, so cute! we're driving it here directly with gpio pins from a qtpy samd21 chip, which, according to the internet is Not Something One Does - you're supposed to use an lcd segment driver or at least a chip with built in peripheral. and we sorta see why - there's a little ghosting from how we're driving the segments, even though we're doing our best to depower between common-pin swaps. still, its legible and allows for quick testing. this appnote came in handy to show how the 'ac' waveform is generated: http://ww1.microchip.com/downloads/en/AppNotes/doc2569.pdf one fun thing to learn is it isn't 7-segments-plus-3-commons, but rather 6-segement-select-plus-4-common with a bit of multiplexing thrown in! #adafruit #lcd #display Visit the Adafruit shop online - http://www.adafruit.com ----------------------------------------- LIVE CHAT IS HERE! http://adafru.it/discord Adafruit on Instagram: https://www.instagram.com/adafruit Subscribe to Adafruit on YouTube: http://adafru.it/subscribe New tutorials on the Adafruit Learning System: http://learn.adafruit.com/ -----------------------------------------

The Apple Disk ][ drive is a converted Shugart drive that has three power supplies: 5V, +12V and -12V. The 5V and 12V are for the motor control. Negative 12V is a bit of a pain to generate, but thankfully the -12V seems to only be used for biasing a trim potentiometer. So, we don't need a lot of current. Still, we do need to generate -12V, let's take inspiration from the classic MAX232 RS232 driver chip to find a charge pump converter!

we see our QT Py ESP32 pcbs have shipped, so it's time to wrap up this design with a tester. like the esp32-s2 qt py, we're using a raspberry pi to test because its a convenient way to run esptool for uploading data and wpa cli scan, to verify the signal strength: we program the test board with access point code, then check the rssi on the pi side. if we get a good signal we can be confident the antenna and passives got selected right. this test seems to be running well, and we'll be manufacturing SOON! #esp32 #adafruit #qtpy Visit the Adafruit shop online - http://www.adafruit.com ----------------------------------------- LIVE CHAT IS HERE! http://adafru.it/discord Adafruit on Instagram: https://www.instagram.com/adafruit Subscribe to Adafruit on YouTube: http://adafru.it/subscribe New tutorials on the Adafruit Learning System: http://learn.adafruit.com/ -----------------------------------------

Build a zoetrope inspired visual art display with 3D printed parts and Adafruit CRICKIT. Party Parrot Zoetrope Learn Guide https://learn.adafruit.com/party-parrot-zoetrope This creates the illusion of motion by rotating a series of acrylic panels that feature engravings of a single frame of animation. A NeoPxiel illuminates the artwork engraving on the acrylic panels and changes color each frame to make a stunning effect. Powered by the Adafruit CRICKIT and Feather M4 running CircuitPython, this uses a DC motor and a photo interrupter to trigger a NeoPixel whenever the sensor detects a break.
