Between you and the internet it seems anything is possible, there is so much untapped talent out there. Here's to your health, and thank you for continuing your engraving.
good morning Shaun, in your opinion what is the best solenoid or pneumatic engraving? in my opinion pneumatic recorder is more practical, l imagine that the sistem of solenoid more expence that penumatic engraving!l am from brasil here l don´t belive thre ins´t kind sistem for solenoid engraving if there is it will very expence to buy,because this l prefer pneumatic engraver,but your informetion it´s very important you show other kind possibilit have other machine the same qualit that traditonal.thank you Shaun for attention and l am sorry my ingles is not good but l learning
Hi Edesio, great question, your English is clear to understand. I haven't actually made the solenoid version yet to try, but from observation from Alistairs great videos i think it is an advancement with subtle control of the pulse in power assit engraving. Providing it lasts with heavy use. All power assit systems do the same simple task, which is to tap the back of a graver in a controlled manner replacing a hammer,leaving your left hand free to turn the work. The homemade pneumatic machine makes sourcing the parts possible and affordable for anyone who wants to make lightning fast progress in becoming a world class hand engraver, like you will be and anyone else who practices for long enough, it never stops :)
Oh, and how's the heating of the handpiece? That's the only thing I'd worry about. Perhaps water cooling would make sense? Wouldn't need much flow, and next to no pressure so extremely light and flexible tubing would work.
Intial reports from Alastair are good. 30 mins engraving warm but not to hot. Solenoid is rated to 70c. When I eventually make one, I will try to make smoke come out of it :)
@@sphinxios That sounds logical thanks. Although do we need a bit extra energy for the umph! to tap the graver, so fine adjustment might take care of that. I think Alastair has it all covered, but got the parts to make and test. I think it's goona be great.
I wonder if there is a better driver architecture possible. I think it might be possible just to drive with pulse length for power and pulse repetiton for frequency.
Increasing the pulse length does increase the overall quantity of power over time but it reduces the frequency. All this does is increase the duty cycle and therefore the heat that is generated. Sphinxios is correct it's the amount of current which controls the force applied by the solenoid. The pwm module does this.
@@alastairduncan4702 I was thinking within a range of source voltages you could regulate the power simply by doing pwm with the same device determining repetiton rate. The extreme version being just one variable width pulse per strike.
@@RobertSzasz yes very likely, my son suggested the very same thing. I may look into it at some point but this will increase the complexity of the Arduino code and it's not clear to me that it's a better solution. The current external pwm is pretty foolproof and seems to work well, it also comes with a visual inticator of what the power output is which I am finding useful. While I find your suggestion interesting it will go on the back burner for the present until I can get around to it, thanks.
Alastair would have more understanding on this subject,it's his work. I plug stuff in, and wiggle wires until it stops blowing fuses. That's as much as I know about magic pixie stuff?
@@express375 I asked you about an old project with a modified compressor. I need to buy a 220v - 12v power supply as from your videos. I have no knowledge about electrical devices. I can't find a 10A power supply anywhere, only 12A. Can stronger amperage destroy the compressor? Thanks

Hive mind!! I might have made something work, but it wouldn't look as cool as this :)

@@express375 thank you for your explanation and that God bless you and yours famile 😃😃🙏🙏
Can we engrave on stainless steel by using this kind of solenoid graver ? How to improve it.
yes , practice
Good job !
Outstanding

if solenoid is used at voltage rating there should be no problems

Very well done, which one do you prefer?
I wonder if there is a better driver architecture possible. I think it might be possible just to drive with pulse length for power and pulse repetiton for frequency.
pulse length has not much to do with strength in the solenoid it is the amps from the power supply that makes the difference

Hello Shaun, can I plug compresor 12v 10A to 220v - 12v 12A power? Thanks

Do you have a build parts list and the program you used on the arduino?
Head over to Alastairs channel, it's all there. Arduino is not to tricky, although I've still got to do that part. If I can anyone can :)
What's the specs of the solenoid? And where to get?
سلام چطور میتونم همچین دستگاهی رو درست کنم.pleace answer me
buy the components mentioned in the video and put them to gether as described in Alistairs vid bro :)
Sir! You are a beautifull beign!
Молодец!Интересно очень.Браво!!!
