I just bought a unit for a cheap price but it may be a flop...there is hum...kinda loud...is this normal for the unit? By the way, tks for the vid! It helped me swap one of them pots!

My dad got me a coco 3 it was never upgraded but i enjoyed a few games on it.. I felt bad because my mom had got me a Tandy 1000 two years prior and it was just so awesome.. I ended up upgrading it and using it to play games from like 1986-1993.. When i sold it with all my boxed games.> wish i never sold it.. One day i went back to visit my dad and someone had taken my Color computer 3 which i was really sad about

you are an american in america why would you use metric measurements, very strange! do you identify as a European. the preset debacle is too funny, one would assume you can read

I have NO idea how many CNC users out there have familiarity (let alone expertise) with GUI programming. I can tell you full stop - this would be an unbelievable amount of code development to undertake. Excellent thought and considerations were put into the design elements to be sure! I edited my comment once I realize it was only an SVG presentation and not the actual GUI as I thought Brenda had written the GUI but it was just not operational yet. I would also like to add that my 30+ years of experience with programmers has shown me that this level of "usage" consideration is rare as often times the developer forgets that the end user cannot possibly know what the dev was thinking at the time and instead can only work with "what is" so GUIs can be very non-intuitive and difficult for the end user.

thats stupid. If you show 10 things on the screen , why needed to use 1 , you have 9 times more pobalilities to make errors , and the cnc machines dont forgive that.

i think most of those fringes you are seeing are possibly just noise from the laser itself that needs to be cleaned and not interference

so what size are these holes? you said around 0.004" hmm so that is like around 100 microns for me i used the concave end of soda cans, cut them out and put my pin holes through their center using a needle and the best i achieved was roughly measured at 400 microns, some other guy said he made 50 and 34 micron which i really doubt as you would need laser to even get close and you would not even be able to see it under a magnifying lens, what project you doing with this interference pattern?

Hey Brenda, hope you are doing well! Found your channel while doing some research on the CoCo3. Great content, hoping you get the chance to return as you cover some great topics with solid information!

If you leave holes through the build, you could add a threaded bar right through. That would bind the various parts together, and add additional strength. I'm not sure if the differential thermal expansion would be an issue.

Is it fast though? You didn't even speed test it. 🙄

No you do not replace the gime chip to use 2 megs there is just a bit of extra circuits added around the CPU to extend the gime's original MMU from 6 to 8 bits the current way of doing this is with a special version of the Protector. I am not sure if this is needed if it is a GIME-X .

I took electrical engineering courses back in the day. I'm thinking about getting a function generator, but I don't know if I want what you have or the SDG1032x. I don't care for the touchscreen and yours offers 16-bit instead of the 14-bit. But would I really need the extra 2? The cost difference is about $140. Can you tell me more of why you choose yours over the cheaper one? Thanks

Another option is the buy one of those monitor risers with holes through them.

I just found your channel, but I really hope you're hanging in there and I'll get to see more of your awesome projects in the future!

Take a Look at EdingCNC or a Professional CNC Control like Heidenhain..and start over..

Gently rub that smog with a pencil eraser , I have a Co-Co 3 and that is how I know a pencil eraser works .

Thank a lot!!!

Brenda where can I get this done? I have no desire to do it myself…

Mine is in the shop right now 🤞

Can you do a video showing how you build the RGB to SCART cable?

Democrats have a poor track record of treating living beings....unless you can vote for them.

I Whish that you was living in Denmark. A lot of things are a lot easier here

Take care Brenda, hang in there.

When I had my collapse lung, and they went to re-inflate it, I had such a bad panic attack on the table. They knocked me out with ketamine, so I did not feel the pain of the actual procedure… But having suffered a collapsed , long myself, I definitely know how terrifying that whole processes. I’m so sorry sweetie.

there is a Y adapter that goes to one sata power cable instead of 2 molex connecters. Startech ships with the Y cable. Sure you could pick one up. The LED lights on the front are nice when u hook them up.

Hey Brenda - I sent a wifi router to you at Campbell Coffee Shop on April 10th 2023 to simply plug in and use at Campbell coffee shop. Hope you are doing OK

Hi Branda i wounder where you got all the nerdiness from "i know that is not a word" ;)

Осень круто!!! Я тоже такой хочу. Ты делаешь большую работу. Спасибо. Я надеюсь это открытый проект.

Being too paranoid about lithium ion batteries. I get lots of these from portable oxygen concentrators, which are high current output to run little compressors. Never a problem being jostled, ect.. (at least these ones).

2 years later and how is it holding up, do you like it? I picked one of these up a little while ago when my trusty 20 year + Weller WTCPT took a crap on me in the middle of a job. Time was of the essence and I was unable to get a replacement Weller so I (reluctantly) settled on the Hakko. Overall its a good unit but I`ve been a Weller guy since the mid `70s. I think Ill repair mine and have the 2 stations in my arsenal.

Looks Great. Is there any more progress on this? I'm on GMOCCAPY but although functional, could do with GUI improvements.

Thanks Brenda for a very informative video. I think your SDC case is brilliant! Since the SDC is a drive emulator, it only makes sense that the case should look like a classic drive controller. And the ease of access to get the SDC in or out with your vent plate is terrific - it completely negates the need for the ugly DIP switch hole I've seen in other 'sealed' cases (seriously, how often do people need to reset those switches?). I'll certainly be using your design for my SDC when I get one!

Do you know why and how these motors fail?

Configuring preset modes is so so simple. There are vids on youtube showing how. In one minute i had my two presets with my favorite temperatures ready to work. Nice station!!!

Look into CRC256...you can get it at home depot...it is an electrical lubricant and works wonders for dirty pots...used it in my Tubeworks stuff and it not only cleaned up the scratch but has continued to keep them scratchy free for 10+ years.

I am drinking hot cocoa while watch your CoCo video lol. I learned to program machine code on a OG silver CoCo that I piggybacked the RAM to 32k. Using a hex editor, I wrote some pretty cool stuff. I guess this was 1982 or so and was my beginning into computers.

It looks like a very accurate stepper motor..

That unused power cord knockout is apparently for 50Hz models, fyi. ✌️

Some of those Vexta stepper drivers have a internal switch to change to step/direction instead of forward reverse. I think mine were UDX or something like that.

There is no replacement for the GIME chip. In fact no one knows exactly what is IN a GIME chip but someone is working to duplicate the functions of the GIME in a project called "GIME X" or maybe "X GIME", not sure of the exact name. However, if you are going to put 2 megabytes in a CoCo3 you need the "Protector". The purpose of the Protector if to supply protection to our aging 6809 / 6309 CPUs so that power and level fluctuations can not overload and damage the CPU. The second benefit is that the Protector sits in the CPU Socket and provides access to the signals needed for the 2 Meg upgrade. Since the CPU must be plucked from the CoCo to install the Protector, might as well add a 6309 to replace the 6809. The 6309 runs ALL 6809 code, but also can run in either 6809 or 6309 more. When using the full capabilities of the 6309, 6809 code still runs, but now you have access to additional machine language commands, and the machine can perform some functions in fewer clock cycles. Fewer clock cycles can mess some things up like if the software has to access hardware ports, and decreased clock cycles changes the speed the computer access hardware. The hardware might not be ready when the software is, as the software finished and is trying for another hardware access before the hardware can provide it. All of these new 6309 features speed up the machine even without changing the clock speed. Also if you do not mind readjusting and tweaking your monitor, you can run the 6309 at speeds closer to 3 megahertz, but again since this throws off the video timing signals you need a monitor that can handle that. Not sure the SCART adapter can. I have seen people speed up a CoCo3 clock speed to 4 megahertz, however this will stain the 6809 (but it has been done) and makes the 6309 work harder, which in the long run will also strain the 6309 more than running at 1 or 2 megahertz. Again speed increases to the CPU speed up all timing signals, and do strain the other chips as well. Changing speeds means the video signals are sped up and no longer work with an unmodified monitor. It is all possible, but it is a lot of work.

I have thought of putting +5vdc on the RGB connector of the CoCo3, you could also disconnect pin 2 from ground to make another usable pin on the connector. You could possibly send composite and +5vdc through the RGB connector, and have a switch hidden in back to switch it back to pin 2 as ground, pin 10 disconnected. Personally I would use pin 2 as +5vdc so that both power pins are together, and composite video on pin 10 since the horizontal sync and vertical sync are already a part of the composite signal and might have less cross-talk issues. After a short section of ribbon, the rest of the cable would be a with multiple shielded conductors, although ground and +5vdc don't need shielding, the rest should in my opinion be shielded from each other and the outside world for the cleanest signal.

We need MORE Brenda videos 🙂

thanks Brenda , for this work ..I just want to know if that code works on Arduino Nano

is there a resistance between terminal on that motor?

The spinning coin analogy was very helpful!

Good evening enjoyed watching your video. I have a question What would a used 602 in good condition be worth in your opinion.

Oh, forgot to mention about BASIC09 assigning 22 bytes for data when you have no DIM statements yet. That's a 22 byte block that every procedure gets to hold special flags, etc. for each procedure (this includes things like whether ON ERROR GOTO is enabled (and what line to go to), whether the program will be BASE 0 or 1, whether you are using Radians or Degrees, and a bunch of pointers local to the process (it's own stack, it's string stack, where it is in the program, etc.)

I bought one last year. They're around $200AUD here. My last small iron was a Scope Minispeed(!) (carbon stub heating element from the 1970s). Despite the presence of both 'Up' & 'Down' buttons on the competitive Weller WE1010, overall I thought this Hakko had several superior features (enough to overlook the cons) - especially the stable stand. Like you, I have little need for password-protected lockout and I might actually use the presets if they were more conveniently accessible.

The original 128K RAM chips are 4464's - these are the chips (used in pairs) to upgrade later Coco 2's to 64K. So you now have two sets of those. :) Also, would love to have you download and install NitrOS-9/EOU, and see what you think of it.

Trying to find your source files for your user interface. Seems the github page is gone. Trying to figure out this patreon thingy as well.
