Urgh videos wont upload on here now 🙄

I have finally finished the spinning cube project!!! 😀 #Z80 #Coding #RetroComputing #SpinningCube

Bit behind the scenes work on the #ZX81 game, but visible progress now: alien paths are set up, the joystick controls are working better, and bullets are in (they don’t hurt yet).

Beaten to the punch announcing my new product here! 🤣 My first foray into hardware to support the Feersum #Microbeast! Available later this week and I'll also show the MB becoming a #chiptune powerhouse with my #RC2014 compatible SID & SAA1099P Soundchip Interfaces after tweaking some #Z80 code.

Its 555 Tmer day! The 555 timer is 55 years old! #555Timer #555TimerDay www.ti.com/product/LM55...

The PicoIDE Crowd Supply campaign is now live! Back the project to be among the first to get yours! PicoIDE is an open IDE/ATAPI drive emulator for retro systems. www.crowdsupply.com/polpotronics...

New Video Released on my channel: youtu.be/gliJVwzRifA

If you fancy digging a little deeper into 6502, this companion video to the first episode of "Thinking in 6502" does just that! 😁 youtu.be/LX20Te9RzP0

Lines drawn... Moving the 16x16 display around to view any part of the 32x32 RAM where graphics are drawn. Next up to get a cube plotted and spinning.

I can now draw lines on my display!!! 😀 The Bresenham line algorithm code is working and my own pixel plot routines are working. I am using 32x32 pixels in the RAM space that I can move around on my 16x16 display.

I will try to finish the spinning cube project this week...

So I was not able to finish this weeks robot in time. Granted, I was close. not quite sure how to handle the fail. especially as fails are stacking up on me. I DID start today with just the assembled cylinder. I had back problems this week, but I cant say without them I would have been further ahead

Here's some 6502 to brighten your Sunday! youtu.be/MOEmQ79nA38 Special thanks to @musicvsartstuff.bsky.social for the amazing backing music

First (glitchy) attempt at getting Citadel 2 (BBC Micro) working on the Acorn Electron 🤪

I tried to compile it for the UNO rev.4 but get this error. Starting to look in to it and seems that incompatible libraries are the cause.

KernelUNO brings a Linux-style shell to the Arduino UNO Rev3 for hardware hacking without recompiling and flashing firmware.

Man, PIO is so ridiculously OP.

I caught a bit of a coding distraction... github.com/ruenahcmohr/... a bunch of code is massing up, so i'm posting it. I'm still working on it :] Lumps that are missing are routines to print lines via tek4010 escape codes, and a brensham alg. @nickt6630.bsky.social @breakintoprogram.co.uk

ok, I have always wanted to do a 3d cube on my apple IIe, so I'm using it to test a bit. One of the "fidgety" factors to this is the Z scaling and the graphic offsets, I have some that work (not in 16x16 yet, but its a 3d cube) is written in BASIC:

Happy 44th Birthday ZX Spectrum

Interesting page on the Bresenham algorithm for drawing lines, circles etc.. members.chello.at/~easyfilter/...

This spinning cube demo in Z80 assembler is the most complicated project ive ever done. Floating point maths routines, calculating x, y, z, with sine and cosine and line drawing routines.

CHUCKULUS BBC Micro Model B version just released ! github.com/Snuggsy187/C...

Its taken so many hours to make this display correctly but its finally done! I tried to make it do wrap around in both horizontal and vertical directions but couldnt get it to work properly and decided to abandon it because it needed more complicated display routines.

Just did a new interview with @thestateofsynth.com, talking all things chiptune 👾 Have a read here: thestateofsynth.com/interview/lu...

Great to see Martin Galway has recently shared his C64 music driver and data for Wizball. For those that don't already know, Martin started his computer music career on the BBC Micro whilst at high school. His first version of YMO's Rydeen was composed on a Beeb! github.com/MartinGalway...

Is robocop still number 1 ……well of course it is …..job done Have a nice weekend and why not treat yourself to something x youtube.com/watch?v=o_ig...

I would of designed it to be un-brickable. Have a backup firmware flashROM. If the machine could not boot from the main flashROM then a power up key press combo would recover and copy firmware from the backup to the main ROM. Users could tinker with the main ROM and restore if it all goes wrong.

Our team received a report of intermittent app outages at about 11:40pm PDT on April 15, 2026. They worked through the night to mitigate a sophisticated Distributed Denial-of-Service (DDoS) attack, which intensified throughout the day.

Are we all back online? I have not been able to use the site for much of the day...

#ZX81 And now we can fly 🚀, and crash into stuff. All coming along nicely.

OK, one more specialpricecoupondiscount prototype. I really want to see this in action before I commit $$ to a full size pcb. This is slimmed down to just the Cap Shift keys, the Sym Shift keys, and the double shifted keys. If this works, it will all work. (baahaahaa....)

One of the oldest most elusive sample mysteries, the stab from Spectrum - Brazil (1990) was finally sourced recently by garx. It's from a 1972 recording of God Save The Queen (from the L channel specifically), which ended up a staple sound in dance music re-sampled from Brazil many times afterwards.

For the hive mind: I'm looking for group purchasing or crowd funding sites to support a larger batch of NanoBeasts, VideoBeasts and potentially launch a couple of other projects. Has anyone experience with Lectronz, Crowd Supply, Kickstarter or others for tech projects? UK based selling worldwide.

Not quite bug free yet but now I can move the viewable 16x16 LED display within the 32x32 pixel game memory space. Theres no limits to stop scrolling over the edges so you will see random dots there. The numbers are arranged as... 0 1 2 3 4 5 6 7 8 9 A B C D E F

locked in, but... cant... unlock.... gonna die, if I cant... get sleep .... soon....

Cool LED panel stuff. Now I just need 15 more of them. 😈

Long gone are the days of having a hardware break down in your computer's user guide

When you cant afford to make a bigger display some compromises have to be made. I chose to make the game RAM space larger at 32x32 pixels so I can create larger objects but have user selectable viewpoint of 16x16 pixels to see any part of the image.

It's looking fantastic. Plug in the USB-C and instant terminal! RTC, I2C and interrupts all work, the beeper is functional, memory is good (the board's, not mine!) and the expansion bus appears to be good. Next job: bring up CP/M

#Artemis II - Todays ‘Earthrise’ image is reminiscent of a similar image taken in 1968 by astronaut Bill Anders of Apollo 8 Bill was 1 of 3 crew who became the first to leave low-Earth orbit and travel to the moon. Pic 1 - Apollo 8 1968 Pic 2 - Artemis II 2026 🚀🌕

control panel of the day #HCI

Its the first Sunday of the month - that means its a Livestream hangout! We'll also be going through 10 affordable Raspberry Pi Pico & #MicroPython projects you can build today! Pi's might have gone up in prices, but Picos are unaffected. www.youtube.com/watch?v=TuQY...
