Thank you for visiting my channel and taking interest in this about page. The contents of my videos are meant to be easy to understand so anyone can engage and try to learn things about electronics, retro computers, programming, 3D printing and other DIY stuff.
Technology and computers play a large role in my life and in my free time I find myself doing various projects. I decided to document and create videos on what I do and share them, so other people can benefit from it.
Check out my second RU-vid channel for some behind-the-scenes footage and live feeds: www.youtube.com/@ezTesting
more videos like this Sir please. hopefully you also make a video of how to build a giant diy led wall composed of a ws2812b 16x16 panel with the length of 12 panels and the width of 20 panels total of 61,440 LEDs. 🤩
I saw a picture of Gary Kasparov using one of these, so naturally I had to find out more about this model. I never knew much about this part of the ST range. They look pretty good for their time. Thanks for the video!
@@ezContents FPGA replacements for the SID chip and the video chip in the C64 have been created. Perhaps someone will create an FPGA based replacement for the ULA.
with your mod does the internal drive operate at the same time as the external drive? Doing the D0 D1 flip does not seem to stop the motor signals going to both when using the external drive as the boot drive.
Thank you very much for this video. I have an issue with this panel. Top half of the board displays only green and blue. It is displaying red. However it works sometimes. I am using esp32 with GpxMatrix library. Exept for the red not showing clearly every thing works nicely. On checking I found the one of wires in the strip connector was open. I changed it. It worked for sometime randomly. Even the orange color I had given shows as green ( because of red not working properly). Can you tell which component on the board could be checked or why this is happening ? . Dc voltage is 5.2 volt from a 2 amp supply. Does the A, B,C,D pins has got anything to do with lower half and upper half ? Lowever half works nicely showing all the defined colors. Thank you
It's been a while when I did this project. You could try to dig into the schematics (link in the description) and see where the signal flow drives the red LEDs on the bottom half. I can't say without diving into it back myself.
I miss my Mega ST2. The motherboard on mine looked like the one you picked up for a spare. Where the RAM chips are is an outline of where more chips could go. I soldered in sockets on all of mine and added more RAM and turned mine into a Mega ST4. I never had a color monitor for it. I got the monochrome monitor as I used mine for Desktop Publishing with PageStream.
I love this. It's very similar to the way an old school CRT would scan, these are perfect for making retro game screens with. The black spacees in between the pixels. Almost simulates CRT perfectly. It would be my dream to see some sort of driver that could arrange an analog signal into an LED matrix cleanly and without lag, but what we have now will work
I.must have owned one of these as my hard drive back in the day wasnt as large as the Megafile units. Sad that i don't recognise it. I wirked all summer at a Texas Homecare DIY store to afford the drive, needed because compiling Pascal code required swapping floppies at every rewrite of the code :)
Hi, I'm using epm7032slc44-10 for my custom made 6502(TTL) cpu computer, but my CPLD has 3.3 V on output, do you maybe know a way to output on this chip 5v?
Thanks. I was making it too complicated, with the Pico and 3.3V to 5V conversions. Although I think that the problem might have been with the in/out pins, which had 2 functions.
Just a comment about the UK mains plug fuse. It's not there because we have 30A ring circuits - each circuit has a breaker - but to protect the device mains cable in case of a short inside the powered device. Many device cables, including in the EU, will melt and/or catch fire, or at least get very hot at currents allowed by the circuit breaker. The fuse should be rated appropriately for the device in question, regardless of the current rating of the supply circuit to which it is connected.
The successor video grabber, which still had this housing in the operating instructions, was completely unusable: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-oRJzF2FXpHY.html
@@ezContentsToday I ordered the Logilink VG0030 video grabber again, which should correspond to the EasyCap video grabber. If you want to rate products extremely negatively, you should do a cross-check. Since the video test was not passed at the time, I didn't even bother with the fact that the audio input should be mono according to ThriftyAV.
I still use my veteran Veleman P8048 board, but I connect a a Pikcit 3 on the ICSP header. right now it has a 4 MHz crystal and a PIC16F84A mcu. The part around the serial port is no longer in use.
RA4 GPIO of PortA is an open drain port so, can LED's be interfaced to other PortA pins (which are stated as CMOS) in current sink or current source methods? Also can an Switch be interfaced to RA4 with an 10k resistor pulled up to Vcc and switch connected to ground to read an active low signal when the switch is pressed?
I have K150 programmer too. But as you said that the K150 chip supports only the operating system of Windows 7 SP3 and below. Then i quit trying after that. I didn't check for years. We need a new programmer 😁
You cauld sniff the web for a Pickit 2 if you're only prgramming PIC mcu. They work in both Linux (with manditory faul language) and even Win 11 Nte win software are free for the PK2.
@ezContents Your project is Great!!! I did build and it works great!!! Please! Could anybody help me? Let me know if Is possible to use this device to test 4116 ones? I know how to generate -5v, +5v and +12v to power that chip. There is a way to use your device to test 4116 too? Very thanks once more!
