Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Hello, i have a question
It might be possible but it may not be the best choice for a beginner project. By using efficient use of attach() and detach() calls I built and coded up a 4-servo robotic arm that runs on just two-18650's (Mimic), but again it's not something you should try as a first project unless you have a decent understanding of stuff like Kirchhoff's Law &c.

Saving Servo Positions
Several years ago I made an arduino based arm and I wanted to do exactly what you are talking about so I included the ability loadstore and reload the arm movements from EEPROM. The project and source code are here and you should be able to re-use the EEPROM storage and retrieval parts of the code (or more maybe).

Help out a newbie
That still very cool and I love the oragami idea! I've looked into oragami for sources of inspiration for different kinds of leverage although I can't say I completely understood the math. 🤪 That's too bad about your 3D printer. I made a simpler robot arm that used 4 servos and I used popsicle sticks to make mine heh.

Two functions of one button, depends on for how long you hold it pushed down...
I wrote exactly what you're describing for the Arduino *I think* and here's the sauce.

Recording and Replaying Joystick data with a Servo
I wrote something like this a few years back. It is a robotic arm that let's you control it using an identically shaped arm that has potentiometers at each joint instead of servos. So one arm 'Mimics' the other. The code for reading, controlling, and recording the movements to EEPROM is there if you want to grab anything. Also, you mention needing to get your button code correct and that same project has an interesting button library I wrote that let's you multiplex one button into tons of different selections by letting you define any combo of (up to 3) short and long button presses and configuring what function to run for that "buton gesture". You might find that useful (or maybe confusing the code isn't ideal for learning from haha).

XRP Ledger AMM Bug Fix Now Integrated: A Detailed Analysis
The bug occurred when a multi-path payment interacted with an AMM synthetic offer, and the synthetic offer required to fulfill the payment exceeded the AMM pool size. In this case, the payment engine attempted to use the single-path strategy to back-out the maximum liquidity available to swap against the pool. Although this condition was properly detected, there was an error on how the payment engine resized the synthetic offer to consume liquidity only up to the AMM size. Instead of using the actual swap rate, which represents the cost of fully swapping one side of an AMM pool, the new synthetic offer’s exchange rate was incorrectly set to the spot exchange rate of the AMM (that is, the rate it takes to execute an infinitesimally sized order). Consequently, an AMM operation that should have been expensive became relatively cheap, effectively violating the constant-product invariant of the pool. In this state, another user could deposit funds into the drained side of the pool, generating a large number of LP tokens and taking ownership of the pool. Now that the fix amendment is active, the team has opened a PR with a unit test demonstrating this behavior.

RippleX 2024: A Visionary Outlook into the Future of Blockchain
It’s good news for the builders who have been working round the clock. Tools such as AI chatbots will enable developers to quickly receive answers to their queries, speeding up the process from concept to application. AI Chatbots have already become a part of RippleX’s commitment to making blockchain development on the XRP Ledger more accessible and less time-consuming, especially for those new to the field. This approach will not only foster increased innovation on blockchains but could also enhance financial inclusion, making tools more accessible globally.

Empowering Developers: QuickNode Now Supports XRP Ledger (XRPL)
As developers and contributors to the decentralized, open-source XRP Ledger (XRPL), the RippleX engineering team is excited to announce a major breakthrough in the XRPL ecosystem that will revolutionize the way developers build decentralized applications (dApps).
What are some alternatives?
ButtonGestures - Use a single push button for up to 6 different functions! Button gesture combinations of single, double, and triple-tap along with a long or short hold on the last press make it easy! Functions can also be pre-registered for callback for the gesture that you want. Even easier!
