ok. but how about after the assembly? i was thinking more along the lines of trying to verify if the assembly process introduced any shorts or other problems.

is there someway to test the breakout with power before mating with the T4? seems that if the assumption is the power of the T4 is somehow inadequate [which i doubt] then using a generic power supply to test the breakout for shorts prior to mating might help. i'm not an electrical engineer so i...

thank you for the info and links. i have not worked with pex but with pvc i could use a hairdryer or heat gun to shape/bend. do you have any experience or info on heating pex pipe to shape it.? in the videos it looks like just straight pipe was used. i guess i need to get a section and try it...

i figured it was straight pipe that was needed. i'm just surprised that much light is emitted with the white. thanks for the links. does the code need to be modified based on length of pipe?

never seen stuff like the last 20 sec of the video. is that the flicker? also is that clear straight[rigid] pex? or the hazy? nice project.

i'm not sure how much control over the content of the shared board page on OSH you have but i noticed you have a note about the .8mm on your github and something similar on the OSH board page would be a plus.

this thread has been an eye opener for me. i would have never thought that OSH would just continue churning out defective boards once they were made aware of the issue. .8mm & castellation just don't work with this pcb and they know it yet they keep making and shipping them. i'm glad i've read...

ok. but for future reference i can make a suggestion that might help. i have no idea if it would help in this case. it sounds like it would not. but ive been in similar situations when a secondary pcb was soldered close to a primary and i had a tool in my kit that was kinda shot in dark last...

well since you seem to have written off that t4 you might as well try to take apart. nothing to lose. heating each pin soldered to teensy until you can pull it. gently, slightly wedge a toothpick or similar between the 2 boards at castellations then with tiny bit of flux heat each one , pressure...

there are knowledgeable people on this forum and good tips, https://www.eevblog.com/forum/repair/

yeah. i never have done that because always afraid of hitting wrong pad accidentally. that is too close for comfort for me, but props to those who can habitually pull it off. i have hands that can be kinda twitchy at times.

i have a suggestion on the methodology. when using an inverted teensy/low profile headers in the testing phase it's not necessary to fully seat the teensy. [or any setup/microprocessor] i generally do at most half way. i know the teensy will probably need to be removed a few times and no need to...

@KurtE, thanks. you are correct. i had not realized it but the flex is not optional, it's a must have. only option is host/no host and if you want host then solder flex to board OR maybe wire the T4 /breakout data pads or wire from breakout pads to the flex data line holes. but that's probably...

i remember @loglow saying a some point that if you don't solder the flex to his data pads the host won't work yet i do not understand why i could not use maybe 30g wire from the data pads on the teensy to the data pads on the loglow breakout and also use a regular 8 pin flex. is it because the...

i'd suggest to remove the teensy from the breakout board if you have not already.

the way it worked for me was by adding a pcb, like Michael suggested, the first class shipping was then free. i put Paul's PT8211 @ 3.85 for 3 in with the addon teensy 4.0 and total was $21.85 shipped. i have no idea if pt8211 works with 4.0, i just wanted to test the theory that an added pcb...

loglow, at this point i'm just happy that i kinda slacked off about getting the connector soldered to the teensy the past week and that you included the thickness detail about the flex and the connector you use in your post. now i have good reason to just chill until your stuff is ready. i like...

loglow, i'm wondering if your flex will fit tight in the 609-1788-1-ND connector used on the beta test setups? that connector is a pressure fit, it looks like, whereas yours has a lock tab which you mention helps grip it. i don't want to solder flex to teensy until i decide to dedicate a...

take a look at this thread that discusses some serial monitor issues and a few fixes. https://forum.pjrc.com/threads/54711-Teensy-4-0-First-Beta-Test?p=213526&viewfull=1#post213526

you might need to use latest teensyduino, https://www.pjrc.com/teensy/td_download.html also, there are some ongoing improvements to the serial monitor. i think discussion is in 4.0 beta thread.

ok. i'll try the hand soldering. initially when looking at the part it didn't seem to have enough metal leg on the connectors side and i figured i would not be able to get the leg up to temp. and i can relate Theremingenieur and defragster on the age/vision. i'm 67 and wear the progressives but...

i'm gonna order 10 flex cable connectors because i'm probably going to melt several. is hot air the best way to solder these? i'm thinking not a hot plate/reflow oven because the board is all populated and maybe just tape off the rest of the board and use hot air? any pro tips would be...

hi Paul & Robin, thanks for staying away from kickstarter. looking forward to the release.

supposedly if you are "following" a creator on kickstarter you get notified when a new project is started.

my guess is that you were correct in suggesting there was a short between pins you had been working on. the laptop most likely being low on power because of the battery condition was not feeding anywhere near normal juice to the teensy via the usb and when you plugged in the charger there could...

went to github, https://github.com/EnviroDIY/Arduino-SDI-12 read this, The Arduino Due, Arduino 101, Teensy, and ESP8266/ESP32 boards are not supported at this time. If you are interested in adding support for those boards, please send pull requests. thought i would mention it.

ok. thanks. i sent an email.

ok. one other thing i noticed, (and i'm not an e.e. so if there is an obvious valid reason for this i would not know), is the teensy/chip sector is flipped in relation to the rest of the board and was wondering why? also, is the bare pcb something you have extras of at this time you might want...

looks interesting. on github you have a note that this is W.I.P. and not working correctly yet. can you talk a bit about what the issues are? thanks.

i keep the stuff i destroy in special spot of work area. helps me to remember how dumb i can be. plus, at some point i may be able to fix it, although have doubts about that. but that fuse tip might be worth looking into. i used to jump right in on stuff thinking devices were error tolerant, i...

yes, i was using 1.43-beta2 linked at the top of this page. and i had just fresh installed the arduino as a windows app which was installed by the windows app store. additionally, it was the only arduino copy installed on this machine.

Paul, i'm responding here from an issue i raised in another thread. when installing arduino as an app the install process was handed off to the windows store and it seemed to finish successfully in that the ide would start, run and quit properly. however when installing teensyduino the initial...

Paul, not sure if you have run across this yet but out of curiosity i installed arduino as a windows app and as a result teensyduino was, for me, impossible to install. there was no suitable path listed in the teensyduino installer. as a matter of fact arduino as an app was not even listed in...

it seems to me that someone looking to use a component in a product or a project would be looking for the lowest cost to get the concept done and also interested in the component delivering what is needed and not whatever else it can do. however, there would most likely also be a niche market...

nice project and great presentation. thanks for posting the info.

the projects i have supported on crowd supply have all been shipped by crowd supply. i'm not sure if the campaign owner pays for this service but the way it worked was the owner shipped the raw product to crowd supply and the folks at crowd supply handled the boxing, labeling, and shipping of...

particle has announced a set of devices based on the Nordic nRF52840 , they use a term called mesh network, they will not be released until july at earliest. https://www.particle.io/mesh

it might be because he has only one architecture , the 64 bit one and needs to add the 32 bit architecture to his system. i have the tx1 and it was a dual but i think with tx2 it comes as only 64 bit. 32 bit is armhf. nvidia is not good on error notifications, they leave you hanging they expect...

well, partly because i think cell screens offer increased brightness for daylight viewing over what tablets offer and partly because i'd like to see a project involving arduino compatible interface to MIPI DSI for LCD/OLED screens found on cellphones. there was one that fizzled out a couple...

do you happen to know the name and model of the vintage laptop? looks like an ALPS keyboard. that company is not around but a Canadian company named Matias http://matias.ca/switches/click/ is selling some of the stuff that ALPS made back in the day.. i can't positively make out all the various...

perhaps an option to consider would be 2 cellphone screens placed one above the other in landscape. many cellphone screens are very bright and easy to read outdoors.

@KrisKasprzak, nice project. i enjoyed the video, good job on that and thanks for the code. @mjs513, thank you for the code.

is that the normal way you present a schematic? i'm curious because it is the first time i have ever seen one with black background. and i've been looking at schematics for 45 years. also, it would be nice if you could put a .pdf on a file sharing site that was large enough to allow it to be...

nice work.

there are credits at the end of the video, but, this might be a start or possible source for answers, http://www.designcommunicationsltd.com/portfolio/columbus-asweare/

cheap throw away type cell phone with temp sensor app to call you and ask politely to come light the pilot light.

i'm probably misunderstanding what you note along with the diagram but the fact that both switches activate is not surprising to me at all because you have given all switches a common power lead as well as ground. like i said, i'm probably not understanding the setup but the culprit is 2 being...

hello, so reading your post and not being personally familiar with your concerns , i highlighted the last 3 words in above post and did a google search and what google gave me was 1 link, "wiz850io and oscuino" returns this link https://forum.arduino.cc/index.php?topic=264445.0 which i find...

many years ago i had a flash on one of my old school 35mm cameras that would make a similar "power up whine" as it recharged the strobe like flash. been a long time since i heard that. the other sound was to me a sharp hand clap, i guess that is the clack. if i was sound effects guy i would try...

that page you linked has vertical option . create a sample array and look at the code that is created.
