One year later, this video still holds up! Excellent work Jeff! Thank you

[@mediacowboy9245]

I think the pad 5 would be really awesome with PoE support for in wall mounted touchscreen control for Home Assistant.

[@trustmub1]

I was thinking of the same. One has to only worry about powering the switch

[@CrypticConsole]

Good idea

[@othermod]

Thanks for the shoutout Jeff. Hopefully these shortages clear up soon and I can start shipping PSPi boards.

[@DirkDulfer]

First time I hear anyone mention and linking spring, allergies and CM4 boards in a single sentence

[@countertony]

Both those screens/cases look delicious for a Home Assistant display/endpoint for use in a powered garage or other outbuilding (particularly with the nice big buttons on the second one, for gloved operation).

[@CognosSquare]

[@jbritain]

0:02 I genuinely sneezed as you said allergies

[@JeffGeerling]

It's now been three weeks since my voice has sounded normal :(

[@TheOleHermit]

I really appreciate Jeff's enthusiastic updates and focus on CM4 products. I was about to ask, "What's not to love about CM4?" Then I read the comments of everyone complaining about its unavailability. I jumped onto the bandwagon early, before the pandemic supply shortages and still waited several months for it's delivery. "Snooze and you lose." Yes, some of my other projects are on hold, waiting for ICs, as well. But, the world hasn't ended,,, yet. Vaccines + herd immunity is kicking in, and life will soon return to normal, Folks. If you're still alive and well enough to complain, I suggest taking a moment to count that as a blessing and make do with what we've got for a little while longer. Life has never been perfect, has it? Whining is for children. JS

[@JeffGeerling]

They are available here and there, you just have to either get lucky, or subscribe to rpilocator on twitter and wait for alerts. Hopefully the situation improves this year-I know the volume is mind-boggling right now, but almost all supply goes straight to industry for the time being :( I've also been unable to get a Pi for over 6 months now. But I did see a few opportunities but let them pass by so someone else could have a chance.

[@TheOleHermit]

@@JeffGeerling Thanks Jeff. I still have a spare CM4, so I'm a happy camper. Simply trying to encourage folks to buck up a little during difficult times. 😎

[@kozygeorg]

It is SO exciting to see so many new Pi boards. I just wonder, when is there gonna be a rPi5? seeing as how powerfull the Pi4 is, the rPi5 has the potential to be SO exciting!

[@JeffGeerling]

I hope soon, but I wouldn't bet on soon :( - the chip shortage has delayed so many launches, I'm guessing the Pi 5 is similarly delayed.

[@dmytronikolenko1341]

Let's hope it will be in stock by 2038...

[@yaboiminecraff]

@@JeffGeerling I hope the rpi5 has higher clocked cores and more gpio connectors and mini hdmi or USB c for video instead of micro hdmi my first rpi4 hdmi port broke so I had to replace it

[@kozygeorg]

@@dmytronikolenko1341 and that's the time another cryptocurrency came out... lmao

[@charliemaybe]

I would love to see the pi 5 either strive for a cooler and more efficient processor or more power, but I hope the more power doesn’t need more than just a simple heat sink and a small fan. It would suck to need a cooling solution that is large so that you cannot put it into a small device.

[@DevOdyssey]

05:30 Awesome, the cellular router is on its way! This is the board that I've been eyeing up to make a 4G/5G router with two ethernet ports. It's disappointing that the second ethernet NIC is attached via USB, and diminishes the potential speed, but I feel like that's due to the M.2 slot likely attached to PCIe. Though, depending on the cellular modem, not all support use over PCIe, and rather use USB 2.0 or USB 3.0. I'm also looking at the Waveshare CM4 IO Base board for a possible "homemade hotspot", with a Pi Juice for battery, OLED screen for network info, and connect a 5G modem to it. The Waveshare 4G/5G board looks smaller than I expected, so thanks for showing it off and testing out the cellular capabilities. I feel more confident now getting it for myself. Looking forward to the cellular router video when it comes out 😊

[@davidk7544]

Excellent vid, thanks man! I need to watch several times to catch up on my RPi skillz, and your presentation makes that more than bearable.

[@wingowingo2928]

A great collection of boards there!

[@jmckcl]

It's scankorea! Amazing video. Great content. Thank you Jeff

[@BhavishyaDahiya]

[@Duewester]

Got the Pad5 and printed the case. Mod to the case to make room for a heat sink. Works great.

[@JeffGeerling]

Nice idea; it does get a bit toasty with no fan/sink.

[@tonybaker3880]

Ahhhhhh the router reminds me of my job, when troubleshooting peoples internet they have a 4g backup for their modem. Nice work my friend

[@ClayTheFoxx]

I am genuinely impressed that I guessed the manufacturer of that the 5’ touchscreen pi board just by the packaging without any logos

[@denvera1g1]

That touch screen would be really cool for a car project, with HDMI out you could have a second display for the car's OBD sensors and/or a reverse camera.

[@rmcdudmk212]

That's pretty sweet new gear. Just remember to keep it some place where red shirt Jeff can't find it. 👍

[@L4marca]

I actually use the official 7" touchscreen + Pi 4 (4GB) that has OctoPrint installed (as well as an Pi camera) mounted on the top rail on my Ender 3 Pro. Combine that with the TouchUI plugin, a script to auto start chromium in kiosk mode and it works perfectly to get the full web interface directly on the printer. I also added a small script to turn off the screen after a while if no input was detected. What I like about that particular display is that it runs off 5V directly off the Pi, so no extra power is needed.

[@davidbubble6863]

I got some experience on reTerminal. It got a few quirks like: 1. Display support only one resolution 2. Boot select switch is really hard to reach. Back panel is tight af. 3. Sd card slot is not exposed. Had to take a part the whole casing to insert the card. Unless you use cm4 with internal storage. 4. Button on front panel only support single key mapping. Wish it support combination key mapping. 5. The I/O board didn't like custom power supply, might cause the CM4 to hang. 6. Display is in portrait mode if running without xwindow. Have to edit cmdline.txt to force it to landscape mode. The use case for reTerminal is a little limited for my work environment due to the quirks above.

[@JeffGeerling]

These are a few of the more notable shortcomings. I find it works well in certain use cases, especially as a simple display with a simple input. I haven't really seen their rear expansion connector take off in the way I think they wanted it to, either :(

[@davidbubble6863]

Yes Jeff. The rear connector was the thing I'm interested in as well, too bad really. The form factor is great and useful for simple use cases. I wish they can overcome those short coming in the future. Will definitely revisit again if they do!

[@MarcoGPUtuber]

So much energy in one channel!

[@JLCPCB]

Great video Jeff! 😀 We like it! 🤩

[@OscarSommerbo]

Did Jeff mention the resolution for the pad 5? I missed it if he did, but it was easy enough to find the specs. The panel is an IPS panel with the resolution 800x480.

[@JeffGeerling]

[@noapparentfunction]

just goes to show that many channels use flashy editing to compensate for thin content quality.

[@FunkyMoneyMan]

@@noapparentfunction I agree. They’re all simple cuts in this video with some overlay of audio. that’s it

[@JeffGeerling]

Honestly I learned editing on some of the earliest NLE's (Avid, etc.) and my style is from that era when people were going from film/tape to digital. Experimentation wasn't often rewarded, and I find that story/explanation still is way more important than a flashy style. Getting both would be nice, but right now I still edit all my videos and I don't got the time!

[@FunkyMoneyMan]

@@JeffGeerling well I’m even more impressed that you’re editing all your own videos then. I do some uploading of my own and I usually stick to simple deletions and then upload the entire thing. I’m trying to steal some inspiration in your editing to my own.

[@WhenDoesTheVideoActuallyStart]

Great script writing can very easily compensate for "mediocre" editing. The videos are fine for me.

[@James-no2oc]

Can't wait until I get my hands on raspberry pi4 and cm4 boards again.

[@AshtonSnapp]

Part of me wants to build a CM4 board designed around Picroft, a distro of RPi OS that comes with the Mycroft open source voice assistant. It would compete with Mycroft’s Mark I & Mark II (I believe both are based on a Pi, I know the II uses a 4B), but it would be useful. Especially if I can integrate PoE since Picroft mainly supports voice hats like the Google AIY voice hat. Sadly, I have no idea how to do that.

[@mxBug]

important thing you didn't mention ! the reTerminal COMES WITH A CM4 !!! and it's a CM104032 so it's actually one of the better ones !!

Great video. Can't wait for the 4G LTE video!!!

[@MarcoGPUtuber]

Hey. Genuine question. I know. Shocking. But how long does the 4G router last if I hook it up to a power bank and take it with me travelling?

[@JeffGeerling]

That's a good question. I might have to test and find out.

[@iwinrar5207]

@@JeffGeerling I think that would be a great test. Not enough people talk about how long these devices work when it comes to loads like that.

[@thomasbonse]

I would suspect the specific battery bank and its own efficiency would have a big impact on the answer to your question. As would the signal strength (IE 4G/LTE, 5G, etc.) if the signal strength is poor, then more transmit power is necessary to maintain connectivity (the same is true on your cell phone). While I'm sure this is an idea Jeff Geerling would likely test at some point, the ultimate answer will likely be YMMV, or 42...

It would be nice to have a 7" version with the exact same backside layout-you could then hide all cabling behind the screen pretty easily.

[@theonlynafester]

So many boards!! I am really looking forward to your custom OpenWRT build. I just moved into a new apartment. The landlord includes free WiFi through some UBNT APs they have hanging in the hallway. I love the free internet, but I don't trust public WiFi so I'm working to put in security measures between my devices and the AP. I've never used OpenWRT, but am interested in playing around with it. I plan to test using the public WiFi as my uplink while keeping my devices safely NAT'ed and firewalled behind my router. Not as ideal as a wired connection, but I can't complain about free.

[@JeffGeerling]

Good idea; double NAT can be annoying, but using an insecure public network is much worse! :D

[@mauriceatkinson9520]

I saw one for the LHC in Switzerland. A while back SETI had one of these computer projects going, too. There's at leas 1 dozen of these projects going on that I know of. Cant wait, tho.

[@kelvin1316]

Regarding Home Assistant, there seems to be some controversy around how it deals with the DNS. I believe it is hard coded to use a certain system and not the DNS specified by DHCP or manually. As you are more a network guy I was wondering if you would be able to look into this and maybe explain why it is a problem as some seem to say it is, or if it is nothing to worry about.

[@ArsenGaming]

If that's actually happening, you probably wouldn't have to worry about it. It's a concern for people like me because I have my own DNS server with custom rules and blocklists that I expect Home Assistant to follow. However, it's not too much of a problem because I run OpenWrt on my router which lets me force all DNS traffic through the server I prefer regardless of what any program tries to use. I think the bigger issue here if they're doing this is that they should've clearly communicated it to their users.
