I've had one of these sitting on a shelf in my office for a while now. I grab it every so often to play with it. :D
Me too!
Bro I can’t understand the big babies one even tho I’m 11
You'll get there!
extra long breaks between sentences and paragraphs.
Thanks for the feedback!
I'll be honest and say that given the number of youtubers who talk flatout without pause for thought, it's refreshing to have someone taking their time
@@bikeforever2016 Thank you. I appreciate your comment on this.
Thanks for the video! : ) Can you modify this to be sound active? Like ... to advance the leds according to beats of the music by somehow add a microphone somewhere in there? I have this kit but if there is a way to solder it with this extra I would.
This sounds like a fun idea. I do have a voice activated light soldering kit. Maybe joining them together would be a cool project.
Did you try the obvious first? Asking info from the producers?
Absolutely, @michaelwessel4953 has reached out to both Busch and Texas Instruments. Unfortunately neither Busch or TI had the code. However, Jörg Vallen from Busch has been very helpful and supportive including allowing Michael to publish the extracted ROM code. See more on our project page: hackaday.io/project/197415-microtronic-firmware-rom-archaeology
@@jtjacques Amazing emptiness. No wonder that our best technical achievements must be replaced by AI.
@@y2ksw1 It’s an intriguing thought! The idea that AI could take on tasks traditionally done by humans reflects both the potential and the challenges of technology. While AI can enhance efficiency and handle complex data, it also raises questions about creativity, empathy, and what makes us uniquely human. What are your thoughts on the balance between technological advancement and human experience?
@@jtjacques Honestly, I can't see how AI is ever going to be creative. I am sure, it can do incredibly well with balancing and detecting technology, but it is a total failure regarding new features. It also does pretty well with recalling information, but it tends to make catastrophic failures in judgement. I am confident however, it could do extremely well in reverse engineering, and particularly reading and analysing protected ROM contents.
@@y2ksw1 Michael tried to get ChatGPT to program the Science Fair Microcomputer Trainer, which uses a related Texas Instruments chip. As it did not know the instruction set it seemed that it was more Michael doing the programming and the result was more an example of the "ELIZA effect". See his log entry here: hackaday.io/project/194876-exploring-the-science-fair-microcomputer-trainer/log/227686-chatgpt-35-programs-the-science-fair-in-assembler
No switch...A better project with that was to be used as a night light switching device...
Absolutely! That's a much better application.
Most interesting and informative. My grandfather got my dad a KIM-1 when he was a child
That’s really cool. I’ve been debating getting a KIM-1 replica.
Can your scope do x/y? One of the reasons for acquiring my 2-channel signal generator was to recreate the Lissajous curves my high-school physics teacher indulged us with in a presentation before Xmas. I was hooked!
That’s really cool. Sadly this one is just single channel, though I think there is a mod for it. All the equipment in this video came as a kits. The oscilloscope was actually a gift.
Oh wow, the recreation is faithful enough to do the radio sound trick - is it the same frequency though? :D Nice kit! This was one of the coolest discoveries as a child I had - putting my TI Dataman next to the radio and hearing all these magical-mystical switching sounds.
The emulation is cycle accurate, as far as I can understand. So I’d imagine it is the same frequency.
Love these! I have a few stock-piled for project in my stash - just waiting for the right project...
Wohoo! I got a classic rubber dead flesh Speccy and a 2a as well 😊 hunt the wumpus is more like a TI 99/4a thing for me. Manic Miner, JetPack and Jet set Willy! 🎉 btw, are you into CPC as well? My first 8bit was a 464 in April 1985.
We talk about Hunt the Wumpus in one of our beginner programming classes. I thought this was a really neat version of the game, and super cool that it was retro-ported to the ZX Spectrum. I don't think I've ever used a CPC machine. I might have briefly touched one at the Centre for Computing History in Cambridge. I started with an MSX based Toshiba HX-10.
These kinds of projects would have been in the realm of the Microtronic and Busch electronic kits 😊 thanks for sharing!
Absolutely, when I found out they were made by the UK distributor for Gakken Denshi Blocks, I couldn't really turn them down!
@@jtjacques it seems that these could have been a logical next step after Gakken blocks - you learn how to solder, and even decode resistor color codes! Maybe this is why they included the Gakken block schematics to meet learners halfway in their "graduation" process?
Seems its going viral, nice job! Within 3 days, your Microtronic video got more likes and views than all of my Microtronic videos in 10 years combined 😅
I'm glad people are deciding to learn about this interesting computer. Your videos (and excellent talk) are great if anyone wants to learn more about the Microtronic.
@jtjacques same - I am super excited the Microtronic finally gets the attention it deserves! This is great!
overall your videos are well made. Keep up the great work. Have fun, ignore the critics, and most important, be yourself. I look forward to see what you make next.
Thank you for the positive feedback!
Great video 👍 you're great at explaining the process of what and why you're doing what you do. Looking forward to more videos.
I'm glad you found it interesting. Thank you for the positive comment!

Super cool video, and great idea to use the logic analyzer! I still have an old HP 1662A which is a bit of a retro monster with 2 68k CPUs and B&W monitor etc. (I got it for 50 $ in an EWaste thrift store) - I was thinking about replacing it with one of these nice compact modern USB-based ones like yours, but I use it too rarely to warrant the expense. Thanks for this very instructive video!
Thanks Michael!
Me too ! I have same HP
Good one. I put one of the blue LED kits in my AliExpress shopping cart. :)
Good choice! I think the blue would also look awesome.
This is actually so helpful for me.
Hmm, interesting! I am wondering if we could use one of these to set up a nice Towers of Hanoi demo for the Science Fair trainer :D If we only had some more memory... I guess the controlling Arduino would need to be programmed to execute "macros" based on digital inputs received from the trainer, so that the trainer wouldn't have to do the fine-level motor controls. This might be more practical with a more powerful trainer, i.e., the Microtronic or the Kosmos CP1. Cheers!
That would be cool! Another project to add to the ever expanding list!
That transistor overheats massively, add a larger piece of metal as the heat sink
Piggybacking off this, you may also want to add the toroid at the top - though not sure if you want it to arc or not, I believe the toroid is essential for the low to high voltage conversion
That’s pretty bad ass. I thought it was fake at first but this seems legit💀
wow thats a cool little neon light
Cool stuff!
Did you make this? Was it from a kit?
I bought the kit on AliExpress and soldered it together myself. Link to the kit in the description.
The really nice thing about the Altair-duino is your much less likely to put your back out when moving it!!
I'm old enough to have seen a real one. :)
I got one of these as a child. This was one of my dearest possessions, and I still have it.
Yyyyyyyyyyyy

The camera does not use the standard USB camera interface protocol, so I suspect you will be unable to connect it to a phone. If you'd like to connect it to a computer, depending on which camera model you have, you might be able to find the appropriate driver here: web.archive.org/web/20021215215654/www.digitaldreamco.com/support/downloads/cameras/archive.html web.archive.org/web/20021002221148/www.digitaldreamco.com/support/downloads/cameras/index.html There area also copies of some of the driver CDs here: archive.org/search.php?query=digital%20dream%20camera&and[]=mediatype%3A%22software%22
