I'm glad you like it!

Nice! I've learned I didn't need a fancy fishing pole for pond bass fishing. Caught an almost 2 footer with a spiderman kid's fishing pole. Have you done any durability simulations for different print filaments? Fusion 360 has this feature.

I wish I would have thought of this! Nice work.

Wow! Thanks for sharing.

This is very practical and well-written. Fantastic! Thanks.

I believe you will need to solder a jumper wire between CHIP_EN pin and VCC pin.

It is power hungry about 250ma peak so it only lasted a few hours on my power bank. Try a solar panel and a battery.

I reached out to the developer, Martin Ger, and he stated there is not ESP32 support currently nor are there any plans to port it since the ESP32 is much pricier.

Please post your code! I am looking to do something similar by logging bt scans to csv on sd card.

What exactly does the helicopter do if you were to skip the logic inverter? would it just reverse which of the two coaxial motors run? If so, you could just swap the motors or resolder the motors to a different polarity, right?

That's pretty cool! We made something similar: https://www.instructables.com/id/Cheap-Music-Reactive-Light-Show/

Gosh this is useful! Thanks!

Cool! But how does it balance without an IMU?

Dang! If only I had this tutorial when I had three flatbed scanners!

Awesome!

Awesome!

Way cool! Your writing style is so professional. It reminds me of a course description.

Yes, I think that is possible. For example some commands,set automesh [0|1]: selects, whether the automesh mode is on or off (default), see details here https://github.com/martin-ger/esp_wifi_repeater#automesh-modeset network ip-addr: sets the IP address of the internal network, network is always /24, router is always x.x.x.1set dns dns-addr: sets a static DNS address that is distributed to clients via DHCPset dns dhcp: configures use of the dynamic DNS address from DHCP, defaultset ip ip-addr: sets a static IP address for the ESP in the uplink networkset ip dhcp: configures dynamic IP address for the ESP in the uplink network, defaultset netmask netmask: sets a static netmask for the uplink networkset gw gw-addr: sets a static gateway address in the uplink network

This is really well done. I hadn't heard of the HC-12 module until now.I wish I would have known about the HC-12 earlier before I made my own mailbox notifier using two ESP-01 modules. One was flashed with a firmware to make it a WiFi range extender for the mailbox sensor, and the other as a mailbox sensor with code that connected to the extender, sent a alert message to my phone via Blynk, then went into deep sleep mode until power was disrupted. I used a simple normally closed metal ball bump switch mounted to my wobbly mailbox as the sensor to reset the device, and I pried off the built-in LEDs to save power.Your design sounds more reliable with better range.The code for both are on our website www.makersa.ga if you are curious.Thanks!

This is incredibly awesome! You've got my votes.

Nice work! I made a somewhat similar proximity triggered servo device that only requires the controlling phone to have its built-in hotspot enabled:https://www.instructables.com/id/Versatile-NearBot/It could automatically unlock and re-lock a door latch as *only you* pass by, shut off a sprinkler valve so you can pass through the water unscathed like a sort of suburban Moses, lower speaker volume while you are in the garage band room, trigger a iPod playing a dramatic entry tune or tell a joke while you are in the room, or pause a movie when you get up to use the restroom.

Thanks for the informative instructable.I am interested in blockchain tech outside of cryptocurrency. It has huge potential for decentralization, public ledgers, and privacy.I would totally read an instructable outlining those things with some sort of tutorial if you wrote one!Particularly interested in blockchain ledgers for IoT, automated free market resource allocation, and data ownership rights.My only concerns are the garbage in-garbage out, privacy, and the 51% flaws.Imagine that all of a country's citizens info is stored on a public ledger. If some person's data can be decrypted and read, then it is recipe for authoritarian control.On the flip side, it could go the opposite way and give people control of their private data. With smart contracts and anonymization, individuals coul...

If people lose faith in bitcoin or it cannot be used to buy goods and services, it will lose its value completely! All it would take is 51% of block chain users saying "nope, that's invalid" and the system would recognize it as invalid. the problem is that the 51% could be easily concentrated under one organization with a lot of computing power.What do you think?

What species of chokecherry are you referring to? It would be helpful to add a photo of the leaves and tree for proper identification.In my region, choke cherries are poisonous, becuase they contain cyanide. They are known to make horses fall ill, and can be deadly for humanshttp://www.oardc.ohio-state.edu/weedguide/single_weed.php?id=26

What kind of maximum range are you getting between the control system and the FPV system? In my experience, AIO FPV units have less range when lower to the ground because the signal attenuates to the earth.

Also, here are some cheaper fat shark style goggles:https://www.banggood.com/Eachine-EV100-720540-5_8G-72CH-FPV-Goggles-With-Dual-Antennas-Fan-7_4V-1000mAh-Battery-p-1182469.html?cur_warehouse=CNNice work.

Great work! Thank you!

This blows my mind in how resourceful it is! So you just disconnected two out of three connections in the motor, and it generates AC polarity switching? Any guesses what frequency it switches at? I know a lot of devices require 60Hz.

You can use "%20" without quotation marks between character to use spaces.

https://github.com/martin-ger/esp_wifi_repeaterMaybe this will help? Let me know

Check this link:https://github.com/martin-ger/esp_wifi_repeaterHope that helps

I'm glad you liked it.

I didn't know baking soda could be used for this purpose. I had been using rubbing alcohol and soap, but that didn't work well. Thanks.

This is well thought out and executed, especially the drawers. I like the little personal side comments in the instructable, they make it more enjoyable to read. I have a concern though, can a human brain handle the stimuli from that many monitors at once?

Nice work. Don't worry, your English language writing skills are absolutely fine. Personally, not being fluent in a foreign language but knowing a bit still can be really helpful to understand the English language better. Especially being able to define a word just by its foreign roots or similar words in other languages.

It's interesting how scraps can be made into highly aesthetic works with some craftsmanship.

You Sir, have reached maker pro status.

This is really cool. This would have a ton of uses. I wonder what is the maximum amount of notes that can be stored.

Wow this is really good to know. I've always thought that camera were immune to damage from bright light.

This is actually pretty cool. Nice work. Here's an interesting idea; You could make a 360 degree "aimbot" scanning version of this using an non-contact heat sensing module that triggers a relay which is connected to a spinning base motor on the normally ON pin, and a solenoid to pull the sprayer on the normally OFF pin. The whole unit would spin until it detects heat, then stops spinning and sprays until the heat source is cool again, then it would resume spinning. I made something similar for a flashlight tag robot turret using a light sensor instead of a heat sensor. You could also use a sound sensor as a "hunter hunter bot" which fires back at sources of paintball gunfire. Imagine a quiet study room turret bot which sprays loud people with water!

Nice work!

I had made something like this years ago with an ultrasonic distance sensor and individually addressable LEDs along a hallway. The lamp nearest to the user would light up and shut off once the user passed it. The downside was that the distance sensor was not accurate past 17 feet or so, and the person had to be of average height in order for the sensor to detect them.Your idea is so much more effective.

That's so resourceful! Another thing to check if a fan won't spin is to open the cage, remove the blade, pull out any hair stuck around the motor shaft, then re-assemble the fan.

I like it. Check out my instructable which also shows a simple but unique way to drop a glider or other item from a drone. I used the least often used motion of a drone (rotation) to unscrew and release a glider once lifted to the desired altitude.

This is super cool. Congrats!

Not sure if my last nearly identical comment went through (bad WiFi connection and browser keeps crashing) but I meant to say this is way cool!

I'm not sure if my nearly identical previous comment went through because my connection is spotty, but I am glad you won because this project earned it! Well done.

I'm glad to see you won a contest. Your project earned it!

I can't wait to see this for sale online someday!

I hope to see these for sale someday online! Well done!

This is good to know! Fun fact: LEDs can also be used to detect specific wavelengths and colors of light. This quality has been used to measure aerosol levels in the atmosphere.

This is a neat idea. I wish there were better pictures of the lamp glowing.

This is amazing and your presentation and infographs make it even better. Bravo!

Mind. blown.

Mind. Blown.

Does the ESP32 board use less power when using Bluetooth instead of WiFi?

Nice work. This will be handy for my future projects.Couldn't you just use the servo library to call a specific degree of rotation? I've used one of the servo libraries with a NodeMCU Lolin V3 board based on the ESP8266 chip with pin D2 for signal and 3.3v for servo power without any issues. Does the Arduino IDE have Bluetooth capability with the ESP32? I thought the ESP32 has a bluetooth transceiver built in. How much current can does the ESP32 board output for VCC and GPIO?Sorry to ask so many questions!

cool!

Neat!
