This weekend we got to play with a VFD tube. This ancient technology uses a gas tube to light up segments. In order to activate the fluorescence, we need to provide 20 to 30V DC on the segments. Not a lot of current, maybe 1mA each, but definitely needs to be a high voltage. For lower voltages, we could use a switched-cap converter. But for this, we'll need a proper booster! Let's find a small, low cost, simple, and available boost converter that can give us these bias voltages from 3 or 5V DC input.

This weekend we got a LOT done with new and revised stemma boards! For revisions, we got, assembled, and tested the DRV2605 and ADS1x15 QT boards - both work great. we also put together and tested our qt py lipo BFF and it works great, for our final version we added a battery monitor resistor divider. in order to test the BFF we needed a power monitor like the INA219 and realized at like 1am that we didnt have an INA219 on us, so we ended up bringing up the INA228 prototype we had and wrote a quick driver for it. Unfortunately the INA228 is totally unavailable so it won't be in the shop soon. finally, we got a shipment of some samd21e18's in - from an order over 6 months ago! so we can do some more trinkeys - one trinkey that we wanted to put together for a while was an 'ice tube trinkey' - with a single digit VFD display. First up? figure out pinouts and voltages for this cute IV-3 tube! - then we can wrap it up in a circuit board design.

part of our floppy quest is we want to read mac 800k floppies - partially because there's a lotta good content out there on 800k floppies, and partially because we are still heading towards imaging the prince floppy (which, being 800k formatted made it a bit of a pain to read). 1.4MB floppies on mac are easily readable because by the time they got to 1.4MB apple stopped being clever with their disk formatting. but 800K floppies are really clever/freaky! unlike ibm pc formatting, there are not a fixed number of sectors per track. there's four groupings of tracks, and there are MORE sectors on the outer tracks (tracks 0 thru 31) than on the innermost sectors (64 thru 79). thats because there's technically more surface area on the outer edges of the disc where the lower number tracks live. mac floppies also rotate at different speeds depending on the track, which is also a joy. given its quite hard to find and control those old floppy drives compared to our bog-standard 'shugart 34 pin' pc types, there's incentive to try to get these to read cleanly on cheap and available hardware. (apple superdrives are...not cheap. no not that superdrive, the OTHER one) but the problem remains: the inner tracks have flux pulses that are significantly longer than the outermost tracks, because if we have a flux-per-inch limit, then we have to spend more time to traverse that distance on the inner tracks. and ibm pc mfm-optimized drives do not like this: they really expect the flux to change on very specific timebases: about 2us, 3us and 4us -ish. and once you start reading those longer pulses they get into 10 or 11us and that is much longer than the drive and media expect. firstly, the HD diskette isn't really meant to encode such long pulses, and secondly the disk drive automatic gain control starts getting amped up after 5 or 6us and thinks it must have lost a pulse, so it ends up reading old/weak flux inversions and 'splits' the longer pulse into 2 or 3 ghost fragments. the flux decoder is getting extra bits where it ought not, and gives up. we're going to order some true DD diskettes to see if that helps with the first issue. for the second issue, we tried setting the DENSITY input low but that didnt help - we're thinking we could try to detect spurious pulses to try and repair the GCR cells during flux read. hopefully we'll figure something out? #adafruit #floppy #apple 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 be a hit for anyone who has ever had to add terminal blocks to a design, then dealt with the frustrations and costs of having a mixed SMT/THM process. Presenting... TE Connectivity Board-Mount Surface Mount Reflow Terminal Blocks (https://www.digikey.com/en/product-highlight/t/te-connectivity-amp/board-mount-reflow-terminal-blocks). Yes! Almost everyone has created a design that had a raw-wire to board connection. And a super popular way to make a flexible but durable connection with a range of wire thicknesses is to use the tried-and-true Terminal Block (https://www.digikey.com/en/products/filter/terminal-blocks-wire-to-board/371). Digi-Key carries thousands of different terminal blocks in all sizes, pitches and configuration. Multiple rows! Plug type! But they all tend to be through-hole type. Not surprising, because there's a lot of mechanical torque on the connector when twisting, and also a lot of current passes through these connectors - they're often used for power supplies, and motors, that can draw amps. Given that they are through hole, a selective, manual or wave-soldering step is required for manufacture. (https://blog.adafruit.com/2014/03/26/ace-production-selective-solder-kiss-102il-apex-expo-adafruitapex-ipcshow-ipcshow-apexexpo/) And believe us, while these machines are totally awesome - they also require a lot of maintenance and time to run. (https://blog.adafruit.com/2018/07/02/programming-the-crickit-for-selective-soldering-a-deep-dive-part-3-adafruit-crickit-manufacturing-selectivesoldering/) So we try very hard to go with SMT-only processes: it's a lot faster and cheaper to only use one machine than to use two machines where boards have to move through two machines. We've used some "SMT Terminal blocks" before in products like on our buckaroo bonsai (https://www.adafruit.com/product/4534), which only needs 2 wires connected, and low power ones at that. Since hauling all the PCBs to the selective for just two pins is a total pain, we figured its better to go with this 'side insert' type. It works fairly well but doesn't have the adjustability we love with the cage-type terminal blocks. Which is why we are diggin' this series from TE, available in various pitches (3.5mm, 3.81mm or 5mm) and pin counts, from 2 to 7 pins. They look just like your everyday terminal blocks, but with flat rectangular pads that are bend 90 degrees to the back of the package, and mechanical shear/locating dots that will keep the connector from lifting up. They're even packaged in a chunky tape and reel, ready for use in your machine line. Note that even with the locator posts and large pads, you'll still want to make sure that you don't have a lot of force coming in from the front: The posts will protect against torque from the top but probably can't help much if they are lifted up from the front. If you only need a couple terminal blocks in your design and want to save process costs - or if there's a reason you can't go with a through-hole block - these TE Board-Mount Reflow Terminal Blocks (https://www.digikey.com/en/product-highlight/t/te-connectivity-amp/board-mount-reflow-terminal-blocks) will do great. And, they're available and in stock at Digi-Key right now! Order today for immediate delivery, so you can be twistin' and terminatin' by tomorrow afternoon.

This week @adafruit we’re making a modular case for TFT Feather and Stemma QT sensors. Prototyping a VU meter using a QtPy RP2040, NeoPixels and a PDM mic. Shop talk on using Display IO for Circuit Python to make LCARs inspired user interfaces. The timelapse this week is a potted cactus with hidden storage printed using special quantum filament from Matterhackers. It’s gonna be magical!

This week's EYE ON NPI is going to stick with you for a looooong time - it's 3M's VHB Tape (https://www.digikey.com/en/product-highlight/3/3m/vhb-tape-5906) also known as "the tape you use when you want it to stick together forever". This tape is the stuff of legend - it's incredibly thin but strong, easy to apply and gives you near-epoxy-level strength in seconds. 3M VHB tape consists of a durable acrylic adhesive with viscoelastic acrylic foam. This provides an extraordinarily strong double-sided foam tape that adheres to a broad range of substrates, including aluminum, stainless steel, galvanized steel, composites, plastics, acrylic, polycarbonate, ABS, and painted or sealed wood and concrete. Our bonding tapes provide excellent shear strength, conformability, surface adhesion, and temperature resistance. They are commonly used in applications across a variety of markets, including transportation, appliance, electronics, construction, sign and display, and general industrial. Reliably bonds a variety of materials with strength and speed for permanent applications. Seriously - we've seen it easily attach to metals, wood, plastic, rubber and it wont dry out and peel off like most foam tapes. It's super strong, to the point we often feel kinda weird when we use it because don't expect such incredible tensile strength. You can even build a push-scooter that is kept together just by VHB Tape as seen at https://www.youtube.com/watch?v=rxJ-kU6Z8GY. It's double sided tape. but its sticky enough you cant just have it on a reel like office double-sided tape. Each reel comes with a smooth plastic layer in between - we suppose this is the one material it doesn't stick to very well. Clean both halves with 50/50 IPA. Carefully apply it while still on the plastic reel and then remove the protector. Now press the other half you want stuck together. Wait up to 3 days for max hold strength, but it's pretty darn strong instantaneously. This VHB is VHC (Very Heckin' Cool) and extremely useful when you just want to attach this-to-that, no matter what material or environment. You can get this in sheets (!!) and rolls at Digi-Key. We are partial to the 5 yard 1/2" wide roll which has just enough to be useful (https://www.digikey.com/en/products/detail/3m-tc/1-2-5-5906/5039231) but there's also a 1" wide version (https://www.digikey.com/en/products/detail/3m-tc/1-5-5906/5039233) and we picked up one of each. Whatever 3M VHB tape (https://www.digikey.com/short/bvq23nw9) style you're looking for, Digi-Key has them in stock for immediate shipment. Order today and you can be stickin' this-to-that by tomorrow afternoon!

after nofrendo/NES emulation, the next one we tried is 'gnuboy' which is a gameboy (color) emulator. we remember getting a gameboy when they came out, it was absolutely amazing to play tetris anytime we wanted. really chewed through nicad batteries tho - we had to have one set charge while we played. anyways, gnuboy works a treat and maybe we'll finish super mario world again (there was a submarine, right?) #adafruit #gameboy #retro 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/ -----------------------------------------

from ladyada "we had a lot of success with our retro-go port (even submitted a PR) and now we've got the NES emulator 'nofrendo' working. we're reaaaaally familiar with this emulator, having ported it to the SAMD51 a few years ago (see https://learn.adafruit.com/nes-emulator-for-arcada for deets). its a fairly portable emulator that can run many games. we popped in a micro SD card with a bunch of roms and had a go at playing some of our fav NES games: kid icarus, arkanoid, tetris and of course dragon warrior - which was the first rpg game i played on a console and was totally amazing (and paved the way for jrpgs like final fantasy, xenogears, legend of gaia, etc) i still think about farming those steel slimes... anyways! since the ips 1.3" tft is 240x240 pixels it does a pretty good job of being smol but fitting the 256x240 native resolution. you can either scale the output, or drop some pixels on the left and right. with audio and playback working this may the the smallest pixel-perfect nes gaming emulator ever made :) " #adafruit #nofrendo #retro 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/ -----------------------------------------

After all the functionality has been worked out with a new boards, its time to do last power draw checks to make sure that low power functionality is verified. historically, we haven't cared too much about low power uses - stuff would be plugged into a 9V adapter anyways. but in the last couple of years we've tried to make whatever small changes we could to make our boards work well in deep sleep. this qt py esp32 pico can get down to 70uA which is pretty good! that means the cp2104 and neopixel are not drawing current. given we don't have a 32khz crystal on board, we think this is as long as it gets! #adafruit #esp32 #pico 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 we put together our first QT Py accessory board which turns the diminutive board into a tiny gaming platform with 10 buttons, a TFT screen, micro SD card, and headphone out. The PCBs showed up late last week so we quickly soldered one together and we pretty much got it going! then we ported arcada to it (that's our Arduino button/display library) so that we could do basic tests on the hardware. finally we spent friday and saturday on getting retro-go to work so we could use it as an emulator for nes/gameboy/sms/doom/etc. most of that was picking the right idf, learning how to work with CMake and doing the hardware port to support the i2c gpio expander.

we're taking a short break from floppy disk hacking (don't worry, we're nowhere near done and this will all tie together - promise!) and working on a QT Py gamer backpack we designed. the qt py esp32 pico here plugs into the back to drive the 240x240 IPS display with an SD card slot, battery charging, and an AW9523 GPIO expender for all the buttons. we wanted to make a very smol odroid go-like since that hardware had a ton of support. we've found a great open emulation project with a LOT of emulators supported and a very easy-to-understand structure at https://github.com/ducalex/retro-go so we're having a 'go' at porting it over! we had to use esp-idf 4.2 and this is the first time we've used raw idf and...we really like it! ninja is such an incredibly fast compiler and we like the 'flash n monitor' helper. so far we've got the chip booting and the tft is kinda coming up, just need to tweak the init for the st7789 instead of ili9341. #adafruit #gaming #emulator 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/ -----------------------------------------

jepler picked up some retro Apple floppy disks online. With Adafruit_Floppy and the Adafruit fork of fluxengine, they read out the data and loaded it in a Mac emulator. What a blast from the past, dithered "screen posters" using After Dark technology & comic book artwork. Not all drives can read Mac floppies, a Sony drive worked but a Panasonic didn't. #arduino #floppy #retro #fluxengine @jeffepler ----------------------------------------- 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/ -----------------------------------------

About a week ago we re-spun our ESP32-S2 QT Py into an ESP32-S3 version (the chips are very very similar but NOT drop in compatible!). we just got the PCBs in last night and threw one of these together. compared to the S2, the S3 adds a second core back, and adds BLE as well. while there is no arduino support yet, we do have preliminary CircuitPython support! good enough to test each pin, the analog inputs, i2c control of a display and even connect to wifi to grab some data. there's still more to go but we've got the hardware in a state that's good enough to try and order our first set of PCBs for assembly. #adafruit #esp32 #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/ -----------------------------------------
