2 роки томуAttention: This is a re-published video. During my Summer Break, I decided to re-publish interesting older videos
In this project, I build a timer with an acoustic notification if the temperature for gluing is reached. It switches the gun automatically off if not used for 10 minutes.
When off, it uses absolutely no electricity.
The design uses an ATiny85, a solid-state relay and is programmed with the Arduino IDE.

@nigeljohnson9820 2 роки тому
For years now I have used a hot water tank immersion heater timer to switch off all the things that get hot, or are potentially dangerous, in my lab. The timer is connected to a mains extension block, so all devices plugged into this socket are switched off after a preset time. The adjustment is from 1 to 180 minutes. As the timer, was designed for an immersion water tank heater, it is rated for up to 30 amps at mains voltage. While this is not a true construction project, other than fixing it to a uPVC board and wiring it up, it has been a very useful addition to the lab. All my mains powered soldering irons, heat guns, hot glue guns, etc are switched through this timer. One benefit is that it has greatly reducing the number of soldering iron bit replacements needed, as I no longer leave the irons on for long periods by accident. The original build for this project was inspired by a near serious accident that happened at a company at which I was working. A bench had been left switched on over night, leaving the apparently unused bench soldering iron powered. During a discussion about a particular circuit, the A0 size blue print of the diagram was draped over this apparently vacant bench, and its hot iron. After many minutes, a brown mark appeared on the blue print, this rapidly turned black and burst into flames, fortunately the flames were quickly extinguished. Had the discussion happened later in the day, the lab might have been vacated before the paper diagram showed any signs of burning, and there would have been no one to promptly put out the fire, with the obvious damaging consequences. After that incident, I installed the timer as a safety device in my own home lab.
@AndreasSpiess 2 роки тому
That is a good and simple concept and a very good reason to do it! The usage pattern for my glue guns and my soldering iron are very different. This is why I bought an iron which has an automatic shutdown built-in when I place it in the holder. And it heats up in seconds if I need it. I do not use the glue gun very often. So waiting is not critical.

@ralfjahns3777 2 роки тому
Of course I remember this one and I like it. Real project video, not only powerpoint. But as we all developed our skills in the meantime, I would say: We want more! I learned from Julian Illet, that you can determine if the glue gun already heated up by current measurement because the heat element is a PTC. No need for hardcoded time constant. Additionally, many soldering irons only lower the temperature for some time and completely switch off after a very long time. This would require some kind of dimming circuit for the gluegun. So, perhaps an idea for another video?
@jost459 2 роки тому
I think a soldering iron you need at an evening more often as a glue gun, so sometimes it is better to keep it simple and stupid. Only for an florist this could be fine ;-)
@AndreasSpiess 2 роки тому
I think you are right with measuring the current. I am sure it would work. Like that you would not need to do the testing and it would work also outdoors in winter. My soldering iron has exactly the function you mention and I like it because it heats up in two or three seconds. Unfortunately, my hot-glue guns take much longer . So the advantage for me would be small because I anyway would not wait and do something else in the meantime.
@thorbjrnhellehaven5766 2 роки тому
Depending on how reliable the voltage is from your grid. It can be an idea to measure voltage and current, to calculate resistance. Resistance is depending depending on temperature, but current is depending on resistance and actual grid voltage.
@thorbjrnhellehaven5766 2 роки тому
Curren (or current and votage) measurment can be good to shorten the time to ready-buzzer, if recently hot and not yet cold when switched on again.

Other types of glue stick too like wall plug glue for which my 35 yr old glue gun has a separate nozzle. Drill a hole, blow out the dust, insert the glue gun with wall plug glue and it even leaves a hole ready to start the screw. Works really well. Other ideas - anything that needs to switch off if not used for some time : heating plate, soldering irons, solder pots. Modifiable with light & PIR motion sensor to turn on/off workshop lights & power, etc, etc.

Cool project! I just got a new soldering iron which has a sensor in the holder. It switches off when I put the iron back to it. Very handy.

@@AndreasSpiess I have been thinking of making a better stand for my glue gun, that has a metal pin that sticks into the nozzle openening to block it when placed down, so the pesky oozing of glue stops. Yep your "Selbsthaltung" is pretty clever, havent thought about that way of doing things before. Since my 'lab' is all MQTTd like your, lights go on/off with PIR and timers, it would make more sense for me to control it that way.... I might even turn some devices on before I arrive ;)
@AndreasSpiess 2 роки тому
I only switch my lights with PIRs because I do mot want to switch off my bench power automatically. I want to be sure that I have nothing important going on. But it would save a lot of energy, I am sure because it often stays on without need.

@@AndreasSpiess My lab is my post production studio at the same time, so a lot of audio visual equipment. All is strictly divided into different power system. UPS backed, filtered and RAW grid power for non essentials. Within this space I have tons of desk lights, rack lights and so forth. All lights are controlled via PIR and NodeRed, to remember the last state it was when I left the room - there is no need to turn all back-on when I re-enter the room... only the lights that where previously on. I came up with a very similar solution in terms of warning then you did - just not a buzzer, but a LED light stick, that begins to count down 1min before lights-out, just to remind me to move a bit and retrigger the sensor, or once all lights are off, the LED bar stays on for a 5min and gradually fades-out - a night light sort of speak. All of corse wired onto Siri as well ;).

@Sylvan_dB 2 роки тому
Does your hot melt glue gun have a thermostat or is it thermally balanced? If it has a thermostat it will reach temperature more quickly and live longer as it can use a more powerful element but cycle it to maintain temperature. This is like a temperature controlled soldering iron which might be 70 watt or more and heats in less than 30 seconds, compared to a cheap 20 watt iron that takes several minutes to heat to soldering temperature and will cook its tip while operating as its temperature rises very hot unless actively melting solder. If your glue gun has a thermostat then you could add a current sensor to your circuit to detect when the thermostat is cycling power to the heating element. When it starts cycling off for some significant time the gun is up to temperature. With a little tuning of the algorithm it may be possible to detect when the gun is not used and after too long idle, turn it off. (But it would probably be easier to put a little tilt switch on the gun and run wires back down to your circuit.)
@AndreasSpiess 2 роки тому
I have temperature controlled guns and you are right, I could create a more complex system. However, I am not sure if if would change a lot. A anyway have to wait the same time till it is heated and I want to shut it down after 10 minutes. For somebody using the gun frequently it for sure would make sense to measure current and switch it off only after a long "not usage".

The glue gun timer should be a mandatory safety feature on these devices. While they probably contain a thermal fuse, there is still a fire risk.
