Pi news 27. Raspikey eMMC. Chipsee Raspberry Pi CM4 Portable computer.
First up is story in tech radar pro, and this is a tablet by a company called chipsy and, as you can see here, uh it’s got quite a chunky bezel on it um. So it looks a bit like uh. Maybe original ipad – you can see here that it’s based on a command module, four with two gig of ram 16gb of storage. So it has a two watt speaker microphone, three and a half mil audio jack. It also has the ability to support a 4g module and a front facing camera as well on the back of it. It also has visa mount screws, so you can mount it on a stand so for commercial use. That could be quite interesting. So if we go to the official site you can see here, maybe if we get the black, when it will look a bit better on this picture and then on the back, we have the visa mounts here and they’ve got drop down options, so pre installed os At the moment is just debian and uh colors, black or white there’s, the 4g module which is 64. and then a base stand and all the specs and everything are there. This is the sort of thing i’m more interested in so the command module 4 is like a stripped down version of the pi 4 that doesn’t have all the connections, and so then the idea is to add it, and this is the the whole idea of the Command module 4, that a board is made for it to give it all the breakouts and change the form factor and everything, and you can see all the connectivity on the back there and there’s a manual on the site.
If you want to look at any more in information on it, and you can see industrial pi brochure so for commercial use, i didn’t see anything about battery power input. Current 12 volt yeah it doesn’t, look like it comes with the battery, so it’s kind of a tablet, maybe there’s going to be a battery thing that comes in the future or maybe it’s something i’ve missed next up is a broken raspberry, pi, 4 and it’s. Just interesting because you can see what’s under the heat spreader, so you can see here. I don’t i couldn’t get what had happened to it. Why it’s all full on scratched up it’s like something’s gone over it, but but it’s weird? How many scratches are going across it, but you can see the uh, the processor is there and you can see that it’s it’s properly been snapped in half, but looking at the information, i don’t think they there wasn’t an awful lot. There was some quite witty comments about how it could be fixed. Oh, it is in there, so i didn’t see this before so kind kind of how i figured it would look, but i really wanted to know how this happened, but it was already dead from sitting in a raspberry, pi supercomputer for half a year. I just thought: it’d be a cool experiment to open it up, and it sounds, but with a lawnmower, a clamp and a hammer for your information, okay, so that’s how that’s how it’s come apart! Next, up is from the official raspberry pi blog, and this is a star wars, arcade cabinet that they’ve covered.
So these are super rare and worth loads of loads of money. So the person who’s done this decided to make their own one and you can see there’s some nice pictures of the inside, which i always like, and the interesting bit was the uh, the control bit and uh. It says here somewhere yeah, the atari yoke is considered the holy grail of controllers and again it’s very hard to find. My prayers were answered in october 2018, with a thread on the forum. I was subscribed to popped up with a small utah based startup, aiming to supply replica yokes at a realistic price. So it’s amazing that the amount of energy people put into these. But it is very, very impressive, interesting read and, as always there’ll be links in the description. So next up is this uh tron tribute – and this is another arcade cabinet and uh i’ll – play well let’s pause. It get it full screen rather than play the video, because you can always i’ll link to the video anyway, but it’s got multiple screens on it, it’s full of led lights and it runs from a raspberry pi. So really really impressive. You can see there’s a controller there, as you can see it flashes and just looks. I mean the amount of work that must have gone in that and look on the ceiling, though it looks like it’s projecting onto the ceiling as well. There are more pictures on this story, so if i, if i go back yes, it’s based on a raspberry, pi, 4 and there’s various different pictures of there – and you can see there’s this screen at the top screen at the bottom screens on the side and as You can see from this original mock up.
It has changed a lot over time. Next up is the raspberry pi pico story, and this is tetris but it’s a two player online game of tetris. So it says here finding someone to play game boy, tetris with 30 years later isn’t as easy. So a clever hacker has upgraded the handheld with online multiplayer, letting players all around the world compete with each other and there’s even a battle royale mode, as you can see here from the bottom, the approach not only allows two players on either side of the world. To play tetris against each other using the original game boy hardware, but also a large group of players to compete in a sort of tetris battle royale, given how little data has to be shared back and forth as players fill their screen, they’re eliminated from the game. One by one until the last one standing is declared the winner amazing next up. Uh was a from a comment on uh. This video that i did uh was it last yeah last pie, news pie, news, episode 26, and it was this one here from peter jander. Uh, please do a video review and speed comparison on uu gear raspy key now i hadn’t really heard of this, but it has been out for a little while uh i looked into it and emmc. I i remember having a windows 10 emmc laptop and it was awful, but compared to an sd card for an operating system.
It should be faster and, as it says here, it should have a longer life span. So, depending on your project, this might be something you’re interested in. So in the end uh they’d said: it’s small should have a longer life than microsd higher random speed, also sequential for me, it’s, a big factor, it’s, so small. So i figured i’d have a look at it, so i’ve ordered one and i’ll do a speed test when i get it through and the website, you can see that it looks like this. I owed the 16 gig one which oh well, they actually look exactly the same there’s. It tells you how to tell the difference between the two um, but i thought it’d be interesting to try it and see how it was. It looks like um early on people had trouble with it and it was it’s almost like it treats it like usb boot. It doesn’t treat it like an sd card, but it’ll be interesting to find out uh how it works, uh and sort of play around with it. But it also comes with raspbian pre installed, and it says also provide some tools to make setting wi fi connection and enabling ssh login much easier so yeah. It will be interesting. You can see it’s there in a pi zero, but i’m, probably going to be using it. Mostly in my pi 4.. I bought it from pi heart. I think i paid 24 pounds so more of that in the future.
Now a story from tom’s hardware – and this is how to turn a rotary phone uh, so a traditional phone into a google assistant with raspberry pi – and this is using, i think, it’s a pi, zero yeah pi zero. But the interesting thing about it is uh. You actually pick up the phone to use google assistant uh, so yeah, a nice project that and uh they’ve fully integrated it into it and there’s. Some again, some good photos in this uh, which shows some of the wiring, goes right through the setup as well. So if you’re interested in doing uh, i might look at google assistant or alexa it’s, not something i’ve covered before um but yeah. I might look at it in the future and here you go so the original wiring has been used to uh to work through that very, very interesting, and next up is uh. So i can’t remember it was this story, but i saw a story on this and it’s basically, half life, which actually works really well on the raspberry pi i’ve got videos showing it working at over 100 frames per second, the pc version, but this is a never Release dreamcast version and dreamcast works, particularly well on the raspberry pi, 4, and so i’ve i’ve got it and i’ve tried it out and it’s, not as good as the pc version, but it’s something different to try. So you can see this is a story from september 2000, but if we go to the wikipedia, it tells you that on june the 16th 2001 four days after the release of blue shift sierra announced that it cancelled the dreamcast port, citing changing market conditions.
So it never saw the light of day and uh, so i thought it’d be interesting to try and find it. It was very easy to find, but obviously i can’t put any links in here so let’s start up retropie because we’re in twister os, and so we have that ability. I’Ve already put it in the right place and as you can see, dreamcast is the only game. I’Ve got on this particular one, so i’ve installed from experimental in retropie the redream emulator, and you can see it here so let’s hit start, but also, if i press the home button, i can go to my save point here. We go so load and the buttons are weird. The dreamcast controller only has a left analog. Stick as you can see from the illustration, on the left hand, side there, so the green, red, yellow and blue buttons are moved forwards and backwards. Uh you can. You can change it, but it but it’s still none of them were controls that i particularly wanted to use, although you can completely customize it, so you probably could play around with it. But as this isn’t as good a version as the pc version, i didn’t bother and it’s a bit scratchy on the audio. But it does. It moves all right and it’s, just it’s, just interesting to see a game that didn’t didn’t meet the last day. But actually would have been i’m sure would have been popular, but then i don’t know if the dreamcast was in its demise at that point and it had these loading screens, which you don’t get on the pc version.
So maybe it’s just that sort of jarring bit. That sort of sets it back. There must be loads of reasons that it didn’t come out, but yeah, it seems to work pretty well. Why do we all have to wear these ridiculous ties? Never quite out of that i’ll just show you. The great thing about twister is how easy it is to go back and forth between retropie and let’s exit out and the location of the rom is in the retropie folder, so home pi, retropie, roms and it’s labeled dreamcast, as you can see here – and this is The rom it came zipped i just had to unzip it and put it in that folder and it worked fine. But also, if i go back into retropie, i needed to go into retropie retropie setup. Manage packages manage experimental packages and go down to redream and you can see mine’s installed, but you click on that and then you’d click on install that would install the the relevant dreamcast packages and then once you’ve got that rom in the right place and you reboot Retropie, it will show up and last up so yesterday’s video was this little usb tester, which tests the amount of power that’s been taken by a usb device. Now i had figured i’d put it online with the power adapter and see how much power it takes to power up the pi. Actually, i need to plug in an hdmi, otherwise it’s not going to start out properly, but the only thing about it is that the device is only usb 2 and so in yesterday’s video.
It was a bit restrictive, and so when i was using the m.2 drive and anything else that uses usb 3 because it was going through usb 2, it possibly wasn’t showing as much power as it was using or it wasn’t working to its full potential. So i maybe need to get something different to this. The issue is that, if you’re plugging something in these usb sockets there’s, not a lot of room on the pi and a lot of these devices have uh the usb a or usb c to see female on the back. There are so close together, and these are quite chunky that there isn’t really enough room to be able to do it so i’m, not exactly sure which one, if i send this back, which one to get so let’s switch it on anyway and show you what happens With this just out of interest, so you can see that it powers up and it shows the amount of usage unfortunately it’s upside down. But i can. I can flip that in the edit and if i go to the display it’s, basically restricting the amount of power going through and so we’ll start to see the lightning bolt. It also means that boot is much slower, so it’s it’s heavily compromised in this way. So maybe i need to look at some other way of doing it, but if i show you the device again just so, you can see out of interest, but it would be nice to see those things that use proper, usb 3 to be running at their full Potential and maybe also be running them, sort of copying a long file or something and see if that ramps up the amount of power, and this is maybe why devices are less reliable when you plug too many things into a pi um, but also i found sometimes That usb boot doesn’t work from usb 3, but it often works with usb 2 with some operating systems that i’m having trouble with anyway let’s go back to that screen.
You can see definitely takes a lot longer to boot, up because it’s toggling itself back because it hasn’t got enough power yeah. Eventually it starts up and i get mouse control, but yeah it’s, not working as it should anyway. I hope all this helps thanks very much for watching.
