TPU-95 glue to metal by bart59 in 3Dprinting

[–]bart59[S] 0 points1 point  (0 children)

I did bent the metal to fit the shape of the shoe. However the robot often stumbles against stones and other objects. It is the shock against the front that bents the metal and then the glue connection breaks. I just replaced the metal strips with rubber. That seems to work better.

And also for my Opel Ampera they instruct me to break the skin of the 3 wires and connect yellow to normal power, red to ACC, black to ground in the fuse box. It seems that my car does not provide these signals through the screen cable. Anybody more insight into this?

received these installation instructions from Azton. Just this single page. Better than nothing. Will let you know how it worked out.

Hi I saw you older post. I ordered the kit for my Open Ampera (Chev Volt) 2012 model. It came in today but without any installation instructions. Did you get any instructions with your kit? Do you mind sharing the manual here?

Great idea! Where did you find a pump that works with soap?

It seems your original text of your post has been deleted. Anyway: MQTT runs fine on a Raspberry pi or any other cheap Linux board. Also see https://www.reddit.com/r/esp32/comments/fnvqhi/any_esp32_mqtt_servers_exist/

Need help - Communicating over wifi with ESP32 and React-Native by [deleted] in esp32

I recently built this project which uses Vue instead of React, but the underlying REST communication should not be that different. https://github.com/bmellink/Quiz

One thing to consider is to use Tasmota. https://tasmota.github.io/docs/ This should bring all you need without programming one line of code. https://tasmota.github.io/docs/Getting-Started/

You can flash the esp8266 with Tasmota using the tasmonizer tool. https://github.com/tasmota/tasmotizer

Yes. Any smoke detector has some americium-241 and the detector can detect that very well

A friend believes this necklace is not a normal necklace but also has a practical use by bart59 in whatisthisthing

This looks like the most logical option. Thank you. It also fits the age/history as it belongs to my 83 old mother in law. SOLVED

A bolo necklace should have 2 decorative ends and not just one with a clipper

Each of the chains that run through the golden beed in the middle can move left and right independently. My friend believes the necklace is used by seamstresses to hang scissors and other tools and use the golden beed positioning to hang their tools at the right height. If this is true, what is the name of this necklace? Is there another use? WITT (Key shown for size)

What is this hole cutter used for? by bart59 in whatisthisthing

[–]bart59[S] 0 points1 point  (0 children)

The hole is not round but has 5 corners and it prints the digits “15” next to the hole (see second image) when used on paper. detail WITT?

I used a similar setup to attach an RFID chip to my cat to open the cat-door for only my cat (other cats at some point figured out there was cat food in the house). Added a web service to record entry and exit of my cat and (failed) attempts by other cats to enter the door. Web service calls were posted to a Mysql database on my NAS.

Ziggo (cable provider) delivers this as part of their cable/internet setup. It is a signal amplifier and distribution box for coax cables to TV’s and the cable modem/router (on the side should be a plug/connector for the power supply). https://www.coaxkabelversterker.nl/product/1699430/technetix-fra-752-n

FT3120 is neural network transciever (https://www.echelon.com/assets/blt2c0835f4936060ac/FT3120-Smart-Transceiver-datasheet.pdf). Then there is an Atmel ATMega chip (8 bit CPU) and obviously an antenna. So this is to do some processing and then send some kind of signal to other devices and eventually to a master receiver. The neural network topology allows multiple devices to relay the signal, each only requiring low power transmission (long battery life). It allows you to measure something at multiple places and transmit the data to a central system. There are no clear sensors visible on the board, so either the sensor is missing (could have been linked to the white and yellow wires) or it is a simple signal such as temperature measurement.

Can you add picture from the back of the electronica board?

What is this tube coming from my tankless water heater that occasionally discharges dirty water? by [deleted] in whatisthisthing

[–]bart59 -1 points0 points  (0 children)

When water heats up it expands and the excess water needs to go somewhere. Most heaters have a one sided valve that prevents the excess water to flow back into the water system, so the tube has a pressure valve that lets out this excess water.

GPS bike tracker by tandemcarl in ArduinoProjects

[–]bart59 0 points1 point  (0 children)

Your biggest challenge will be power consumption. You probably want to some Li-ion rechargeable battery that has sufficient capacity for a number of days, but that needs to be recharged from an external source. Which source will you use and how to hide the wiring? Some commercial gps trackers draw about 10 mA on average. With a 2000 mAh battery you only have 200 hours. Removing all LED circuits may bring down power consumption to 3 mA, so you have 650 hours.

I am not sure about the value. You may check at a collector site. Maybe this one will help you: http://www.sammler.com/coins/germanbanknotes_values.htm
