UPDATE on Louis (11/28/2022): I reached out to Louis and he responded back letting me know he is “doing OK, just getting a little older”. He also said he has been busy with projects around the house and with his family, and cleaning up his electronics shed to make more room. I don’t want to go into more without his permission, but just wanted to let all who read this know that he is okay.
Hi F16. I'm glad Louis is okay. He's freed up his lab by now, but perhaps he could provide the community with the solution he used years ago to create the dual power module for this project. Do you think he could just provide us with the schematic? Can you help us by asking Louis? No explanation, just a schematic of the solution used. Would be great. Thank you.
Louis ... we truly hope you are doing fine. Just a 10 second update video from you would really be the best Christmas present for us here. All the best for 2023, Merry Christmas !
2nd April 2021::: Dear Louis, I have been following your channel for many years and have found you to be an absolutely charming, intelligent and keen person. Your videos and projects are brilliant and have been extremely informant. We do not know each other personally, but if I would, I would consider you very sympathetic and a good friend. It's been quite a long time since your last Video and your last comments. It is obvious that something troubles you. Some have posted comments inappropiate to your absence on the channel. They lack empathy to understand, that there are sometimes things in ones private life to which one has a higher commitment. Be it ones own health or that of some family member. I feel for you and your loved ones and wish you the best and if in my or your community followers power... strength, good or better health and all the best!! would be great to hear from you in any which way possible... Take Care Pierre Kiefer
26 May 2022 ::: I have thought twice about saying something like this...... But, I fear that Louis is no longer with us, looking at the timeline and any chit chat on his website, the latest reply I can find was December 2018, and one comment lower down about 2 years back according toy YT, I think that the pandemic may have taken its toll, I do hope that I am horribly wrong and that Louis is still here but just sick and tired of certain disrespectful comments that have been made. This man is one of the few who is able to explain and teach theory in such a way that one could understand it. Louis, May you be blessed in all you do. You have been a great inspiration to many of us that follow this channel...
I've had the very same fears and worries. His videos and projects are among the absolute finest and most educational Ithere is, and I treasure them highly.
@@F16_viper_pilot Thats very good, hopefully he returns when he feels like it. I would much appreciate new videos from him. Thank you very much for letting us know. Love from Turkey...
The amount of effort and attention to detail you put into your videos is always impressive. Seriously.. the explanations, the whiteboard drawings, and so on.. it's all very much appreciated. Fantastic job.
You should have a lot more subscribers than 27K . Your channel is excellently edited and explained . Thanks for your contribution to electronics and engineers , enthusiasts .
Just wanted to say "thank you" for all your videos and projects. I know it's now been years, but just wanted to stop back by and tell you how much I appreciate what you did for a guy that had more curiosity than brains. You helped relieve a bit of the "brains" issue with your videos and the time you took to explain each thing. I loved your teaching style and the way you started each project in a "crude but works" way and modified it in logical steps until it was a good lab worthy piece of equipment. Miss the videos but hope you're keeping healthy and happy in whatever you are doing nowadays!
You are one of few here on youtube that I must see! I understand that you have a life to live, but we all miss your talent and great videos! You are like the best uncle one can have, despite never to meet you in person! Have a great day!
Although we are not longtime friends, for some reason I feel we are. I hope you and your family are well. I sure miss your projects. Real electronics! Can't beat it. Hope you can come back soon.
your videos are the best of the best in the electronics department. Thorough explanations, affordable and useful projects, I learned so much from them. I'm really sad you're not posting anymore. I just hope everything is ok with you and hope that sometime, somehow, you'll come back and teach us more and more!
Hi Louis, Thanks VERY much for all your work in making these videos, and the associated blog/website. I've been using them to help teach me about electronics: I've been more of a user of electronics before. I see a gap in the activity, and I wanted to say we all miss you. Keep well. Loyal subscriber in Sheffield.
Having only recently discovered your channel I'm gradually working my way through. I just wanted to thank you for sharing your knowledge with this relatively new and inexperienced but enthusiastic hobbyist. I really enjoy the way you deliver the tutorials. Please keep them coming and thank you.
I have no idea why your channel isn't more popular. But you have a loyal fan base! I've learned a lot from you. I hope you're OK and that you'll continue to upload videos.
Evening Louis! I've been watching a few of your others as well - beautifully presented and explained in every one! I'm employed in Industrial Electronics, but I am primarily trained as a repair engineer rather than design, and this is why your projects appeal so much, as you explain the design principles! HUGE Thumbs-Up from me, eagerly looking forward to Part 2 Chris Williams
I would like to thank you for the contents of your channel, my workbench is becoming complete with your equipment, in addition to being excellent, the content very well explained ... I thank you so much for sharing your knowledge, please continue your excellent work. Ernando from Brazil.
Noticed you checked in a month back. Glad to hear you’re OK. Miss your presence. I learned a lot from your projects and built many of them. In fact I still have 2 to finish.
I wonder why Mr. Scullcom didn't upload any new videos in the past 8 months. I do check his channel now and then for new projects. Since December I asked myself, if this gentleman is still doing well? If you read this post, sir, please leave a message. Greetings from Germany
I was wondering the same. He did mention in another video that he had some other commitments keeping him away from projects. Hope all is good, and he is able to return soon.
Hi Peter, Thanks for your message. Yes I am still fine. Due to other commitments over the last few months I have not had the spare time to make any new videos, sorry about that. I will try and do some updates as soon as I can. Best regards, Louis
@@scullcomhobbyelectronics1702 I too have been concerned about you friend and I'm pleased to hear that you are OK. No rush, but when you find time I would love to see more from you in the way of videos because they are some of the best on youtube IMHO. Robert, K6FNI
Dear Mr. Scullcom, it has been over 2-1/2 years now and I been hoping to both see you back and to finish this project. Your videos were unique in that you did the full round trip in both hardware design and software. So your videos are very-much appreciated and needed and so your absence from TH-cam is very-much felt. But I must ask you: In all honesty (as a long-time viewer), will you actually be coming back (as you alluded to in your comment-replies) or is this the last video from you? Thank You!
@Scullcom Hobby Electronics, Hope you are doing fine, i miss your little project/tutorial video's hope all is well there and that we may once more love your vid's
Morning Louis! I'm looking forward to Part 2 and any further parts! I did notice in your demonstration that the triangle was slightly distorted at the corners and the square-wave corners a little bit on the rounded side! Will you be covering upgrades/developments regarding these slight waveform distortions in the next parts? I would be making one as a mains-operated bench project using two ready-made +V, -V and +5V psu board kits - is there any objection (from a performance point of view) to doing this? One final point, I'd love to see a video from you on making front panel cut-outs, etc., for an LCD module as used here - any chances?
Afternoon Louis! Everyone who views your wonderful Channel is really concerned for your well-being Sir! I'm going to be ordering my PCB for this when I get paid in a couple of weeks time and we're all anxiously waiting for Part 2 and subsequent instalments! How far have you got with software and design improvements - does V1.7 you've provided include the things you mentioned that needed dealing with at the tail end of Part 1?
I've have a couple of commercial func. Generators; and I have an XR-2206, as well as 2 ICL8038. Although I don't need another F.G., It looks like I may build this. I have a number of test equipment device's in a case in the trunk of my car. So this could come in handy, and add to my collection of test equipment. As always, Thumbs-Up!
I'm looking foreward to the completion of this project. I hope you are well and could you let us know if you have a patreon account or something like that? Thanks very much for your thorough and informative videos.
Hi. I know it has been some time since part 1 of the project but I have just discovered it. The links to the gerber files and Schematic are not working. Is there any way to get hold of them? I have looked at number of projects and yours is by far one of the best. I hope all is well. Love your other projects.
Hey Louis great video. I read the comment for the reason why you haven’t made any videos. Hopefully soon you will get some spare time because you’re really good at making them.
A long awaited Scollcom video. I was getting worried :), did you drop out of youtube or gotten ill, good to see you back strong as ever. It will be interesting to see where you take this fine project, i will surely be waiting for part 2. Nice touch with the AM funktion.
Thanks Flemming. Yes its been awhile, I have been busy doing other jobs at home and at my mothers new house just lately so had little time for electronics. Regards, Louis
Afternoon Louis! Any more news on this project? I've just received the main PCBs and I'm looking forward to the power supply and display sections for this, as we're all at a sticking-point awaiting your next instalments on this!
What software was used to produce the PCB component layout graphic that is found in the PDF zipped with the schematic and parts list? Is it generated in KiCad? Thank you Mr. Scully for another great project.
Hi, I use KiCad for the schematic and PCB design. For the component layout I use the layout image from KiCad and then enhance it and add colour using Paint Shop Pro software. Regards, Louis
Perfect solution and thanks. I'll share with you my project later, which I've done the same Project using FPGA (with DDS concept), I know that FPGA is little bit expensive. the range I got was between 1- 1000'000 Hz. Is there any way to go beyond this range, i.e. more than 50MHz? I appreciate your experience and Hard-Working. thanks again
As always, thanks for sharing your work. I've been working on a project with a AD9833 DDS signal generator module (which cost me £3.55 from eBay) being controlled by an Arduino Nano. Have you thought about using this instead of the XR-2206 ? That makes it easy to display the frequency because that's what you configure in the software. I just have to get the gain and offset issues sorted with my op amp (AD818).
An elegant design. Looks awesome. Your MK1 version also had PWM, are you intending to implement that feature in this design too. Would you be considering making the “final” PCB available as you did the Electronic Dummy Load?
Thanks Bruce. As I have a few spare PCB's for this project I have posted a set of PCB's to you in Australia (the Function Generator PCB and the Power Supply module PCB I am working on for Part 2 video of this project). Regards, Louis
Nice project as always. I like your Videos and builds. I have just one minor complaint: wouldn’t it be better to trim the lower end of your dac output analog like the upper end rather ten to limit the resolution of the nice 12bit dac to less than 11 bits effectively. I know it’s a bit nitpicky but if one would like the extra fine grain frequency tuning 12 bits are better then 11 or slightly under.
Thanks for the comment. In this situation we need a voltage swing which does not go down to zero so I set the DAC output to a fixed lower limit. There may be ways of enhancing the resolution which we could look at as we progress. Regards, Louis
I had the circuit board printed and populated. I have good power going to the board. I have downloaded all the libraries necessary to make the arduino sing. All is good. It boots up with his message (yay), but then the rotary encoder wasn't working correctly. It would try to change the multiplier through rotation and not the button push. I double checked all wiring and paths and they are ok? Has anyone else made this project yet? If so, did you get the encoder to work properly? I have double checked the gerber files using gerbv and the board is manufactured just like the file, so it isn't an error in producing the board. Any advice would be appreciated. By the way I have a few extra boards made up if anyone else wants to give this project a try.
Very nice as always, I'll be looking forward to future updates though. I'm disappointed that there is no display of the frequency or digital control/display of the amplitude. The lack of an amplitude display is why I never made your Mk1 version. And surely it would be easier and better to software control the range? Then just use the encoder to go from minimum to maximum frequency.
Hi, Thanks. This is just Part 1 of this project. The initial software I put together for Part 1 of this project will change as we progress. The display on the LCD will also change as we progress. It is my intention to add some form of frequency display on the LCD. The features and feel of this Function Generator project will change as we advance its operation and interface. Regards, Louis
That's why I'll be looking forward to the updates. I always admire your designs and love to see the functionality improve as they progress. I've learnt a lot about circuit design design from watching them evolve.

Hi Rudy. Will cover the power supply in part 2 as soon as I can.
As always, thanks for sharing your work. I've been working on a project with a AD9833 DDS signal generator module (which cost me £3.55 from eBay) being controlled by an Arduino Nano. Have you thought about using this instead of the XR-2206 ? That makes it easy to display the frequency because that's what you configure in the software. I just have to get the gain and offset issues sorted with my op amp (AD818).
Hi,
Thanks for your comments. I have purchased a few AD9833 chips to have a look at and may use one in a future project.
Regards,
Louis
An elegant design. Looks awesome. Your MK1 version also had PWM, are you intending to implement that feature in this design too. Would you be considering making the “final” PCB available as you did the Electronic Dummy Load?
Thanks Bruce. As I have a few spare PCB's for this project I have posted a set of PCB's to you in Australia (the Function Generator PCB and the Power Supply module PCB I am working on for Part 2 video of this project).

Louis
Scullcom Hobby Electronics Thank you very much. That will be very very appreciated.👍👍👍👍
Nice project as always. I like your Videos and builds. I have just one minor complaint: wouldn’t it be better to trim the lower end of your dac output analog like the upper end rather ten to limit the resolution of the nice 12bit dac to less than 11 bits effectively. I know it’s a bit nitpicky but if one would like the extra fine grain frequency tuning 12 bits are better then 11 or slightly under.
Thanks for the comment. In this situation we need a voltage swing which does not go down to zero so I set the DAC output to a fixed lower limit. There may be ways of enhancing the resolution which we could look at as we progress.

Hi Louis Hope that you are well. Can you include the schematic for the power supply? Thanks!
ever coming back Louis?
I hope you'll have a new video soon
Dear Sir, I hope you are doing good... I used to watch your videos. I miss your project videos
Hello, congratulations. I was wondering, how old are you? Until what age can the electronics hobby be continued? Thanks.
Morning..... I have been watching your channel. I am a beginning electronics hobbyist. Which of your projects would be good for a beginner?
I had the circuit board printed and populated. I have good power going to the board. I have downloaded all the libraries necessary to make the arduino sing. All is good. It boots up with his message (yay), but then the rotary encoder wasn't working correctly. It would try to change the multiplier through rotation and not the button push. I double checked all wiring and paths and they are ok? Has anyone else made this project yet? If so, did you get the encoder to work properly? I have double checked the gerber files using gerbv and the board is manufactured just like the file, so it isn't an error in producing the board. Any advice would be appreciated. By the way I have a few extra boards made up if anyone else wants to give this project a try.
Friend you disappeared.
It's all right?
When will we have new videos
Very nice as always, I'll be looking forward to future updates though. I'm disappointed that there is no display of the frequency or digital control/display of the amplitude. The lack of an amplitude display is why I never made your Mk1 version. And surely it would be easier and better to software control the range? Then just use the encoder to go from minimum to maximum frequency.
Hi,
Thanks. This is just Part 1 of this project. The initial software I put together for Part 1 of this project will change as we progress. The display on the LCD will also change as we progress. It is my intention to add some form of frequency display on the LCD. The features and feel of this Function Generator project will change as we advance its operation and interface.
Regards,
Louis
That's why I'll be looking forward to the updates. I always admire your designs and love to see the functionality improve as they progress. I've learnt a lot about circuit design design from watching them evolve.
