Good morning all little gray packages, and that can only mean one thing it's, postbag. So I'm gonna start with these two I, believe, they're, the same item or very similar. There might be differences let's check it out it's, an ole ahead with four pins, so it's, and I squared C, OLED let's, go from the other one, which is and I squared C OLED. Now what I'm interested in is which way around VCC and ground are this one is VCC then ground, what are these? And which is the most common layout?
Well, despite these being. From completely different sellers. They are actually the setting part number this RH, one, eight, four, six, B, so they're, identical, and they're, VCC ground, they're, actually the same as this, and they're, actually the same I think as this layout, which I used, but I do have some which are ground VCC, just gotta watch that let's open these up and take a look at them. Do they have? For example, an address, yes, they have a little link there for address changing that's hideous look at the angle of those pins.
Not. Good let's check this one out I, can't cut through there, very easily it's. My completely blunt knife it's, very safe because it's completely blunt. Um, this one is at the same year, it's identical actually I think this one has got bent in the post and I should be able to straighten it, because they weren't wonderfully packed where they just dumped loose into one of those gray envelopes. Okay, let's see if they work, oh, and what color are they, oh I can't see if they work on here, because this little of it. Goes ground VCC.
So I, can't, put them in here because they'll blow up I wonder if I can load in an OLED running a Milly's count on here, knowing that this one goes VCC grant I should have mount that on there I have on the new version this, which is in, oh, and I changed this to have four lines using a slightly more compact font for percent humidity, temperature, Celsius volts and amps they're dummy fields at the moment, but that's how it's going to look I found this old NATO in a box. And it does seem to. Be a tighter fit in here, I don't know whether it's got thicker pins because, it's older, and they're sort of reducing the size of the pins ever so slowly over time, maybe, but that does seem to be quite a good fit in there. So hopefully I'll only have to hold the OLED at a funny angle and I can get this to work I'm just running up the Arduino software, I don't, really, oh here we are. Yep, it's, uploading, yeah, there we go some flickers, and then it will transfer to the other one while it verifies that's quiet. Slow icon feeling, this is the old we'll use the old bootloader because I've had to select it right that should be the OLED program in there.
Now is it going to talk to this OLED I'll probably have to reboot it? Initialize. The OLED, yeah, okay, that's, not too good. This is VCC ground, I'm, pretty sure it is that's a bit tighter in there, maybe that'll work better its reboot. The Arduino, oh, yeah, there we go so that one's blue. And this one then get it in there and hold it at an angle and also reboot that.
Ain't anything so why is that not behaving itself? Another guy? Oh, yeah, there we go.
Oh, and that one's. White that's. Interesting did I order blue and white let's have a look.
So this one is white 128. 64 OLED point 96 inches about an inch diameter bit less, oh that's. So obvious, why did I even say that two dollars forty-three free shipping from Bravo p3? And the other one I was also white 128 by 64 Oh loads.
Well, it's the same thing. Isn't it that was 267. These prices might have changed actually because I. Think these are the prices now not necessarily what I paid I just went for the two cheapest ones from sellers I'd. Never heard of this one is sweet and light, but they all seem to work don't. They how about this one, which has the red tag on it, and which was one I already had what does that do reset?
Will it work? Oh, yeah, oh that one's white. Okay, then well, moving on.
Okay, next up. And this one it's going to take some explaining, but I'll do my best it is this let's open it up. It is an FPGA let's get in a.A bit closer on this FPGA it's, an alt error, cyclone 2. Now this is an old FPGA. And in fact, the latest software suite from Altair ER, doesn't actually support this cyclone 2. So you have to load up old software to even get this thing to run. Now, how did I suddenly become interested in FPGA?
Well, it's a long story ever since I, put my video content on library I kind of got into the cryptocurrency side of things that library offers then I started looking into cryptocurrency mining, using CPUs GPUs, a six and. Then FPGA and then I got hooked on FPGA it's, not specifically because I thought, this would be able to mine cryptocurrency that would be very complicated to achieve, but I just got hooked on it and started watching videos on FPGA isn't. It all look like quite firm building logic blocks in these things anyway, that was the sort of route to this quite where I'll take this I, don't know, the other problem with this is it's, not very visual. And if you look at all the FPGA videos on YouTube, they have got. Many views because there's, actually not really very much to show now FPGA is had, mmm, dozens, I. Suppose you could say even maybe of IO pins and there's, a sort of matrix Inge system where you can allocate your logic, pretty much to any I/o pin, so I thought it should be possible to build this in an FPGA.
It has a lot of outputs. Of course, this has always it five-eighths, I. Think, no for tens that's, right? Forty LEDs. This is the 10,000 years shift register where you take outputs far down the shift.
Register line put them through an exclusive or gate and feed them back into the input. Now you could model that in an FPGA and have masses and masses of LEDs connected to this thing. I'm, not quite sure how I would go about doing the link from this to an LED array, possibly a PCB for that. But anyway, yeah, I thought that would be a challenge to model the shift registers in here and have this do this count thing now I bought this, because it was cheap. And as I say, it does require old software ID, a like a.
Package to program, this I can go back even further, actually, because there are these things called Cpl DS, which is sort of the forerunners to FPGA and or I could go forwards. They've got boards that are more expensive. But they've got the newer chips on them, which are supported by the current quarter, software package, so I'm, not really sure which direction to go and I've done this before both things like this, and then never really done anything with it.
So how far I'll get with this I don't know, So this is the item it is the Altair FPGA cyclone, cyclone 2 and then that's the part number, and it's causing a development Bob there's, not much on it. You can get some of these where you get the little programmer, which plugs into one of these sockets, which is the USB blaster JTAG programmer, I didn't get that, and I will need a JTAG programmer. So I can't do much with this until I buy that you can't, buy them on their own $11.
85 is one a free shipping from DIY box. But you can get Cpl DS, which are. Sort of primitive simpler versions of FPGA. This one's, the altered max to Fisher is altar.
Yeah, that's his I'll tear on it. And this one is just five dollars. Eighty-six still got lots and lots of pins on there to play with that could probably do the 10,000 years-- shift register as well.
Maybe I'll get that there's. The JTAG programmer sake, right? Let's. Do this one, and it's an old one and says on it USB break out lots of USB break-outs by the look of it. Mmm.
Okay. So these are little USB micro sockets. Just soldered onto a board, and then you get the breakout of the five connections. Now what was my original idea for this I think what he was some crazy idea of putting lots of power banks, five volts, power banks in series, using these things so that you've got a high voltage from those power banks. And then transforming that down to lower voltage higher current some-some bonkers idea like that then I thought, well, possibly they could be useful on something like this. So rather than using a NATO you. Could use a pro mini and have this little board it's on the floor now to open another one this little board on here to provide the power input socket, and then a pro mini which, of course, doesn't have the USB socket, or the course the USB to serial converter that was my second idea, and I've got 10 of these.
Now, yeah, here they are 10 pieces 5. Volt micro, USB breakout. These were just $1.99 for 10, and they came from Thing long Mini. So there we are these are today's postbag items. Now, a big thanks to my.
