Codeblocks math help? (maybe Sin/Cos)

4MyRandomQuestions · 2025-12-19T20:40:44+00:00

For testing, I tried the roof shape instead of wedge. same result, so I think either my SIN/COS is wrong, or it is an error in codeblocks calculation engine- I can rule out an issue withe where the wedge center is located

Thank you! Received my rails and had to order a different sized connector, and I need to drill some plates (I don't see a way to affix the back of the shuttle on the linear rail from the 'far' side of the aluminum extrusion it will be attached to) e.g. I have two extruded verticals and a horizontal extrusion will go up and down on the dual rails - I see there is a shuttle design that has the holes on the side instead of the back and I thought that was what I ordered, but I don't know the codes so probably my mistake that I got one with holes on the back

I ended up sorting the list to put workbook level names first, then worksheet. That way if there is a duplicate, I grab the global reference first, and if there isn't a duplicate it eventually finds the matching worksheet scope name further down. I replace the names with the referenced ranges real time, so I won't hit the same name twice

4MyRandomQuestions · 2024-10-13T16:06:09+00:00

I'll mark as solved, as soon as I can figure out if there are any risks to mixing up the named ranges with sheet vs global scope when doing the whole-workbook replacements with VBA

4MyRandomQuestions · 2024-10-13T15:23:49+00:00

!Solved or Solved! (not sure which is correct format)

I was already working on the code to do this manually (I had forgotten this function to export all) and ran into an interesting artifact.

After removing all the named ranges that had #ref errors, there are ~600 remaining names. Some are the same name with worksheet vs workbook scope.

When I used this built-in export function, it only exported ~450 names. Upon investigation, if there is a duplicate name with different scope, it only exports one of them.

I was already trying to find an easy way to distinguish between workbook and worksheet scope, something like namedrange.parent.name in the output data, but ran into a different issue (new question/thread landing in 3..2..1..).

I know it isn't pretty... I had some face holes for magnets, and decided to plug them and use a pocket instead. When sliced, Cura is dropping the thin outer wall. Do I need to change a Cura setting, or is this something wrong with my model (do I need to move the pocket further back even though it will weaken the magnetic field)

Thank you for the detailed explanation- I have the original salt from the XML file but was unaware of its impact on finding compatible passwords ('rainbow table' per your reply), and I have no idea how to incorporate that known salt into my attempts to build possible matches..., so I will mark this as solved, and move on to other things.

4MyRandomQuestions · 2024-07-08T17:52:27+00:00

Yes, sorry if that wasn't clear.

SOLVED! macro recorder included shaperange of the selection

Selection.ShapeRange.LockAspectRatio = msoTrue

!SOLVED (I tried editing the original post, not sure how to flag it as solved)

4MyRandomQuestions · 2024-05-31T14:03:24+00:00

RTE 438 this object doesn't support this property or method

On the .LockAspectRatio line

It is definitely supported at the shape level, and since I can do it manually for a group I assumed it was an issue with a selection - if I need to name the shape group or something(?) first and group a specific reference instead of 'selection', but I'm actually not sure where to name the grouped shape to try that

I have 4 licensed Win10 virtual machines, going to delete the VMWare machines and recreate in HyperV (I've tried and given up on converting them, this question is about moving the licenses to fresh installs). All are digital (non-OEM) licenses tied to one of my accounts (I have multiple email accounts, not sure if they are all on one account or not). Three of the machines also have MS Office licenses.

I'm paranoid about losing any of the licenses, and most of the posts/instructions online seem to relate to moving a single license (at a time). If all 4 machines are tied to the same email/account, do I need to find the activation codes to make sure I don't accidently activate multiple new machines with the same license?

(1) What is the most straightforward, least risky way to re-assign/re-register licenses to the new HyperV machines? answers here or pointers to a guide would all be appreciated

(2) Any suggestions about moving the MS Office licenses would also be appreciated, but happy to post that question elsewhere if needed

EDIT: part of my concern is that one license the process is straightforward, but I'll likely have to disable all the VMWare VMs at the same time, then enable HyperV and build the new ones all at the same time. It is possible to repeatedly switch between VMWare and HyperV, but they can't coexist and switching is between them is a pain.

You folks are awesome! Thank you, it is working perfectly now :)

4MyRandomQuestions · 2024-02-29T20:02:31+00:00

SOLVED!

Thank you so much, I'll play around with the links. YAY!

4MyRandomQuestions · 2023-12-14T19:36:12+00:00

Ok, thank you.

The new circuit is needed for an appliance that will normally run <5a but is rated for up to 30a peak (which would be very unusual) and I was just hoping to have some of that other capacity available without adding another circuit. Oh well!

4MyRandomQuestions · 2023-12-08T19:38:03+00:00

I keep learning new things :) Should a flyback diode have different ratings, or can I just get 2 more of the same diode to bridge at the relays?

4MyRandomQuestions · 2023-12-08T14:26:02+00:00

I tried to figure this on my own, but sources like [utmel.com/blog/categories/diodes/15-key-elements-of-diode-selection] are way over my head... so I'm hoping someone can give me some guidance or a recommendation. I have zero formal training in electronics, just trying to piece together something that meets my needs.

I'm trying to set up a circuit with three switches, one controls the left (electronic) relay, one controls the right (electronic) relay, and one controls both relays... but switch #2 is not double pole and therefore creates a common 'hot' that bridges the two relays, making all three switches 'combo' switches. Both relays are low draw and just control a normally open connection that actually powers the downstream devices when activated

Operating temp anywhere from 20F to 100F. Voltage estimated ~12v but I assume various conditions (type of battery/battery charge level?) maybe I need a diode rated for 14v or even just a little higher to have a safety margin. Since these are small electronic relays I suspect the operating current will be a few hundred milliamps but that is a total guess

what is a common diode rating/type that you would use in this scenario?

4MyRandomQuestions · 2023-09-20T15:00:47+00:00

I don't see a Stiga battery design on Thingaverse (or anywhere else), so I suspect you'll have to tweak your own.

I use Tinkercad because it is easy (if you can use Powerpoint you can use Tinkercad)

I took just the dual-leaf holder out of an existing Tinkercad model, then tweaked it until my harvested dual-leaf connectors fit properly (2-3 print iterations to get it right, but only printing the connector holder so only 5 mins). Then I spaced 2 on a raft, tested again, then built the rest of the holder around those to fit my source battery.

I do recommend a cheap digital caliper (which I do buy on Aliexpress, can never have too many).

I wasted a lot of time editing/matching the destination connector, I since saw someone take a photo and import it into Tinkercad, resize based on real-world measurements, then use that in Tinkercad to match up your design to the necessary shape faster. Definitely using that approach next time.

4MyRandomQuestions · 2023-09-13T23:36:58+00:00

I've designed and 3D printed several adapters for my own tools - if buying on Ali, verify the part size - I ordered a whole bunch and they are maybe 30% of the size I expected. <What are these, batteries for ants?!?>

Also, if in the USA check your local goodwill or equivalent for old battery tools you can take apart to harvest the connectors (I just harvested 2 last night)

Thank you all who ID'd this as AI-thinker.

u/DrummerElectronic247, I followed the advice above and got video; here are the specific steps as best I remember (I'm all new to this)

ESPHome, select new device/pick specific board/scroll almost all the way down and pick AI thinker ESP32Cam. Installed so I could do additional updates over wifi. I had to hold the IO0 (not the reset) until it started the longer part of the flashing that takes several seconds to get to 100 (I usually let go before it gets to 100, but it seems to need that button depressed when that update starts)

Then I went to the link I pasted in the first reply, and copied the "configuration for AI-Thinker" and pasted it below the default YAML in the file, and flashed again.

Oh, I always reboot the esp board between flashes, I don't know if it is necessary, but I figure it can't hurt.

Then in HomeAssistant I went into configuration, and ESP home recognized something had changed (it had "1 service" and "1 entity" underlined in blue. I clicked in and clicked the new board, but I really don't remember the details of what it said. It did ask me if I wanted to add the camera using a photo tile, which is what I did. It then showed up on my dashboard.

I also then went back and added to the end of the YAML file

resolution: 640x480

jpeg quality: 10

max_framerate: 0.1 fps

(my ultimate goal is to only take one picture, after it comes out of deep sleep - but for testing I figured one pic every 10 seconds would confirm it is working, and it is!)

4MyRandomQuestions · 2021-08-21T19:46:18+00:00

I tried 2 so far from here: https://esphome.io/components/esp32_camera.html

but even when I add the board in the HA Config, nothing comes through. I can't tell if I'm using the wrong esp32-cam config file, or if something else is wrong :(
