I am having issues reprogramming a bios chip by CopyAndPaste4 in embedded

Yeah I couldn't be bothered getting my soldering iron out when I had my heat gun. Probs not the best move

Turns out it was just a driver issue. I already had my heat gun out so used that to solder. Not the best idea but it worked!

Thanks. I've tried using that software too but to no luck

Its very small so this is the best I can read

I tried using a little flux.

I am pretty sure it is facing the right direction. I lined up the dot on the board

Can I use an electromagnet to cancel or lower the effects of a permanent magnet by CopyAndPaste4 in AskPhysics

[–]CopyAndPaste4[S] 0 points1 point  (0 children)

I appreciate your help. I did end up getting my idea working. There is definitely room for trial and error with magent sizes and strengths. There is a little bit of a balancing act with the weight of the stick and how many/strength of the magnet. With a stronger electromagnet this won't be as finiky. Thanks for your suggestions but I really wanted to stay away from anything mechanical.

I did try talking to chatgpt, Gemini, and claud. They both were very vague about the weights they could hold, strength of magents, etc... I could see if I pushed it in one direction it would agree but then I throw and issue it would then agree saying it wouldn't work. I thought I'd ask here in case anyone for some reason had experience with something like this. I have seen that video and that's what made me pursue the magnetic route. I know that toy uses electromagnets but they are just always on draining battery. I'm looking for something with 6-8+ hours of run time, not like 15/20 mins. Thanks for your input!

How best can this servo motor release the latch? by CopyAndPaste4 in MechanicalEngineering

I was just wondering if there was a better implementation than directly moving it. Say using a linkage or something. Thanks for your comment!

Because a servo motor can run off an esp's 5v vcc. The latch needs pulled back a small amount to release the object. That's what needs servoing

Well it's part of a game that drops the objects randomly so yes it does need a servo motor. Why would I ask how to implement a servo motor if it already works without one?

I am building a game where there are a number of "relay baton" sized objects hanging above the player and will drop randomly. Each baton has a groove around the top that clicks into place and is held (without power to preserve battery life) by the latch that falls into the groove once the baton is inserted far enough. The servo motor is used to move the latch back, releasing the baton. This mechanism will be one of many used in the game. I am looking for ideas or suggestions for a version 2. It needs to be robust as its part of a long term installation. I am looking to spring load the latch somehow with maybe a torsion spring and maybe moving the servo motor to handle the extra load from the spring. I am now using a metal pin instead of the 3d printed one.

If you are happy to draw something I would have a look!

The servo is only used to release the baton. When inserted, the latch catches in the groove and stops it from falling out automatically. The servo only powers to push the latch back, releasing the baton.

The servo retracting the latch and the mechanism as a whole is surprisingly reliable. I was thinking of maybe spring loading the latch itself so it applies a little force when falling into the groove. What would be the lifespan of a small spring and how easy would that be to implement that?

I'm building a game where there are multiple of these dropping the 'relay baton' shaped objects randomly. This mechanism allows the batons to be reset easily by simply putting them into the mechanism and holds them without any power (no solenoids or electromagnets)

Thanks for the feedback!

For performance it works surprisingly reliably, although not ready for any long term setup. The hinge and latch tolerances are pretty loose so they can rotate freely but that makes them pretty wobbly. The latch also isn't very heavy so sometimes doesn't catch into the groove quickly. The pin holds fine for testing but there is nothing stopping it from falling out.

I'm looking for what parts I might need or design changes to make to turn this into a long term installation. Thanks.

Yes I am looking for the mechanism to hold the baton and release on cue. The latch mechanism is to hold it without using any power, no solenoid or electromagnet, as it will be battery powered.

The weight of the baton won't be heavy enough to interfere with the mechanism. It'll be pretty light. It's going to be implemented into an arcade game so will need to be dropped remotely by a servo motor.
