Hi Martin,
Here is a picture of the ISO-TECH IPS3202 power supply image plugged in and ready to go.
I gives a dead steady voltage and current output as it is, but only if you want zero volts and amps. I imagine the actual power supply will have a slightly wider voltage range than my paper version. :-)
Cheers,
Phil

Hi Martin,
I suppose it is not fair to enter the giveaway with my existing power supply project? So I think I will try some AM of FM circuit after finishing the supply.
I was thinking about placing a picture in my lab, but I have no lab, so it is not my case :)
-
Hello martin
thank you for this opportunity as you can see in the image i have no power supply just using some old transformers and an lm317.

...to enter the giveaway with my existing power supply project...
I would like to know the answer too, since I have a PSU project as well, though everybody knows how I'm progressing with that. :)
Many thanks for Paolo and Martin for the offer!

Hello Martin,
Here is a photo for the ISO-TECH power supply competition, sadly in order to get my entry in before life takes over I have not tidied the desk, but it all adds to the character! As you may see I definitely need a good quality power supply - and the prize would be really appreciated! - here's hoping!
Regards
Tony

Hey Martin,
I will enter as well! There is just enough room above my oscilloscope in my homebuild cabinet, should fit like a charm :P!

Hi,
here is my small bench.
-
Hi Martin,
thank you for many hours of informative and entertaining videos. Also I'm not new to electronic stuff, I learned a lot.
I placed the ISO-Tech power supply right in front of my unfinished 4 output power supply which still lacks it's most critical component: The analogue regulator part. The development of the regulator lead to massive output oscillation which heated up the output cap until it smoked and cut power. So this is how my forum name was born ;)
I hope the real ISO-Tech brings a little more colour to the photo.
Cheers,
105°C cap

See how well it would look in my Radio Amateur Shack, it would be the Newest thing I'd have if I was lucky enough.
All the best luck to everyone.

Hi there,
Here is my work bench. I already built my own programmable power supply. You can see it working on my youtube channel HERE (http://www.youtube.com/user/noob64ilive/videos)
-
Mine, sorry it's a bit messy and the photo isn't that great, but hey I have a space waiting for this ISO-TECH 3202 ;)
-
My workbench runs on entusiasm, mini stuffed dogs full of static charge, smiles and an ISO-TECH IPS3202 cardboard power supply feeding my 15V DIY power supply, and yes i hacked it so, it works ;)
-
Hi Martin
Here's a photo of my rather confined space with the ISO-TECH PSU sitting beside my HP meter.
Keep up the good work.
Cheers

Hi Martin,
Long time viewer, first time poster.
Here's my desk/workbench:
-
Hello Martin,
Thanks for all the very informative videos. Love watching and learning.
Here is my "workbench" setup. Its not much, but its all I need right now as I am still learning.
-
Hello!
Great forum and YouTube account! Here is my attempt at entering this giveaway. I "followed" ISO-TECHs google plus page but couldn't find out how to "plus" or "like" the page, but I am doing this all via my cell phone because my computer is down at the moment. Also, wasn't sure if I was supposed to add the pic of my "bench" to isotechs page or just here or both. At any rate, here is my bench with the power supply. I just got accepted to an electrical engineering program and I start in January--so at the moment I pretty much own nothing lol.

Hi! I gave +1 and posted a comment on the ISO Tech Google+ page showing my wish to participate in the giveaway for the oscilloscope. I wasn't sure where to post, but I hope it's valid. Thanks!
-
Hello everybody,
Also left a comment and a +1 there. Looks like not a lot of viewers are entering for oscilloscope ;)
-
I'm starting up in electronics, so the power supply will be perfect for my bench.
-
Thanks to everyone for the great response thus far.
I know some of you have been working on power supply projects already and they certainly can be entered.
I will give those folks starting from scratch the benefit to request a little more time if required.
At some point...this draw can't go on indefinitely...I will announce a date that the designs need to be completed using DesignSpark PCB.
Cheers, good luck and have fun doing it.
Martin.

Hi! I'm in! Need power supply since I have only 89's old Russian supply, which is awkward to manage sometimes.

Hi Martin,
I am a first time poster too here.
This is one of my workbenches. No shelves yet and it is a complete mess.
The other half is at a 90 degree angle so it is difficult to get it in the same picture and it is messier too...
I have 2 linear PSUs: 1 AA4tech and 1 HP6632b right now.
I am unwilling to open a google+ account.
-
Martin,
I am also a first time poster. I really enjoy the videos. I am learning a lot from your videos.
The ISO-TECH IPS3202 power supply would go really great on my work bench.

Hi Martin
Thank you for the opportunity to ease our work with the professional ISO-TECH IPS3202 Power Supply!
Great tutorials, very well explained.
My small working space, with all my DIY soldering stations, 0-25 V power supply and ESR - meters.
The ISO-TECH PS would be most helpfull when building various electronic boards :)
I would have joined the Oscilloscope contest, cause my first successfull project, many years ago, was an AM radio (one transistor, no PCB), with a big tuning capacitor of wich I was quite proud at the time, but to be honest I'm not familiar with the Design Spark PCB software.
Cheers, Adi

Hi I am in for the competition.
-
This looks like a very nice power supply. I'd like to enter to win it! Here is a photo of IPS3202 next to my ancient CRO.
By the way, I'm completely new to Google+ and I hope I'm doing this right. I '+1' and commented on 3 posts related to this contest (user "Anmore Wood-works").
Cheers!
-
I've been considering a ... special... power supply project for some time, so this looks like a good opportunity to start building it :D I'm not gonna ruin the surprise, but I'm guessing you guys will like it. So count me in for the scope contest.
I'm currently waiting for some eBay shipments and learning DesignSpark PCB. It's not too bad, but keeps crashing a lot...
-
Hello Martin,
Here's my humble workbench, :D :D :D as you can see I have only the basic tools. I am a student and I'm still a beginner in the world of electronics. Currently I'm studying and experimenting about Transistor biasing and with this cool ISO-TECH IPS3202 - Programmable Switching dc Power Supply, will surely boost my learning process and experience in electronics. Thanks!

Hi guys, and thanks to Martin for this new contest.
My idea is for one of the two projects: and in case of radio, has it to be RX or TX (or both)?

I have been watching your videos for a while now and this competition peaked my interest. Does the power supply project have to be a bench top lab power supply or can it be a DC-DC switching supply to power a product?

I have been watching your videos for a while now and this competition peaked my interest. Does the power supply project have to be a bench top lab power supply or can it be a DC-DC switching supply to power a product?
I would also like to add to this question.
1. Does it matter if its linear or switching?
2. Do we need to implement both voltage and current adjustments?
3. What voltage range must it cover, and how many amps output?
4. Do you expect some smart features like logging, micro controller circuit, multiple information on a LCD or similar?
I am asking all this as I have a power supply I built a few months ago, but there were some problems with proximity of bridge rectifier and high voltage stuff to low votage, and when bridge rectifier heats up it affects some resistors, thus affecting output. It is a basic power supply based on LM350 with a 10 turn pot and LCD display.
I was going to upgrade it with watt metter kit from Franky, but not sure if I am going to do current limiting circuit. Micro controllers are currently out of my "league" :D
With all these questions I wanted to get a "feel" of what is expected and don't want to embarrass myself with too basic presentation for you all :D
Keep on great work Martin.
Thanks,

Hi everyone! ;D
This is my homemade project to enter the competition:
"1st Prize - ISO-TECH IDS6102A-U 100 Mhz Oscilloscope with Arduino Kit"
"2) Build a power supply circuit. Create a circuit diagram with DesignSpark PCB (http://www.designspark.com/) and upload it here to this forum topic / thread. Upload a photo or video of your breadboard circuit."
I had build a homemade linear power supply with two transformers 8):
-One with 12V-AC and 5 Amps...to test motors...low voltage heaters....something thet needs max 5A..etc.
-And a center tap transformer 2x12V and 1 Amp....For powering low power amplifiers....op-amps......radio receiver....because I can build a power supply with +/GND/- ouput power.
I have used for the regulation of the voltage dose integrated circuits:
-LM338 for thepositive ouput voltage (12V amd 5Amps transformer);
-LM317 for the positive ouput tvoltage ( the 2x12V and 1 Amp transformer);
-LM337 for the negative ouput tvoltage ( the 2x12V and 1 Amp transformer);
And the comon components/schematics:
-Bridge rectifier;
- filter caps;
-imput and ouput protection with fuses;
-Line(LC) filter;
-Radiator for the ics;
-Potentiometers;
-switch;
-rotative switch( 4 positions);
-2 leds;
-ETC.
The case is from an old 220V AC voltage regulator....I will post some pictures with the remaining transformer ...pcb-s...from the old 220V regulator(it was broken by the rain:))... I drill/cut holes for the 220V socket..potentiometers...fuse..switch...banana ..banana jacks...etc.
The schematic is assembled with the help of my knowledge..datasheets...and experimenting.
This is the full bench power supply schematic(will be somewhere in the post)
Some pictures with the power supply:

Hi Martin and Iso-Tech sponsors, I'm going to be entering this compertition Thank you.
I wasn't sure how to enter throu the Iso-Tech Google+ page so I had to post here. Sorry.
-
Hi Martin Ive been a avid viewer of your YouTube channel for some time. I really enjoy what your doing and like how you have taken the time to answer my question via Youtube much appreciated.
Anyway here is my predicament I really wanted to enter the competition with a power supply design but life recently has taken over and I'm worried that I may not have the time (I'm sure you understand). This being said I was wondering if I can enter the other competition if I fail to meet the deadline and also when this deadline is likely to be.
Anyway loving your work keep it up.

Hi Chris,
My initial intention was for a bench power supply but it can also be a switching PSU for a product.

Hi Balsa,
It can be linear or switching, it can have voltage and current adjustment or just single output for a specific product / device. I don't expect smart features.
I'm trying to keep the design open so anyone feels they can give it a bash. Obviously if someone produces a nice variable voltage and current PSU with some clever logic it may stand a better chance in judging. But sometime a well executed simple design can win the day.
Cheers,
Martin.

Hi Kris,
Thanks for the post. To be fair to everyone you need to commit to entering just one of them. As our life is also busy (already started packing up to move again...) here, I only see the final draw and judging happening early to mid Jan.
Hope that helps.
Cheers,
Martin.

Thanks for the reply martin that should give me time Ive now got the control side made up and the control program running on a pic18f4550 I'm trying only to use stuff that I have knocking about and stuff that I can salvage from things.

Hopefully I'll be able to replace my LM317 supply built in 1980 with the ISO-TECH IPS 3202. (I finally added a panel meter a few months ago).

Some month ago I found in my parents attic my old (east german...) electronics experimenters set that I used for learning electronics as a kid. I had too many memories connected to it to throw it away, and I thought that maybe my son will use it one day to play with it and learn something useful...
So when I watched Martins contest announcement video, I remembered what the first experiment was that I did as a kid: building a (medium band) AM receiver. So this looked like the perfect idea: build an AM receiver with the set, and then have my son hear some radio with it (and maybe we can, afterwards, build an even better version together, so he knows what my hobby is about). So I looked into the included manual (the set was still complete :), and decided to build an "audion receiver" (see the image for a schematic, or the ZIP for the DesignSpark PCB version).
Unfortunately I found out, after getting only static noise in the speaker and looking for errors for an hour or so, that the last radio station I could receive in my area has been switched off a year ago. Bummer. No fun, nothing to show.
Fortunately for me the experimenters set had enough parts to build a small medium band transmitter (which is also part of the manual - see for the attached schematic too). So I went ahead and build a small transmitter, connected it to my receiver (it has not enough transmit power to transmit via air). And that was more of a success - I could receive the 1kHz signal, though it was not very loud.
So it looks like one of the most fun experiments for electronics beginners won't work anymore :( And I cannot report complete success in building a functioning... But it still was fun experience, such a trip down the memory lane...
Btw: I wrote a more detailed report (http://blog.hendriklipka.de/archives/2013/12/memories_and_an_old_kit.html), especially about the old experimenters set, on my blog (http://blog.hendriklipka.de).

Is there any updated information on the contest ?????
-
I finished my project and it's 95% working, still some adjustments to do.
I'll try to film a clip and upload it to YT soon.

Hi Folks,
Sorry, I've only just reached the point where I've almost caught up with communications before I start doing more videos. My plan is to install the firmware in the ISO-TECH PSU to correct the issue it has and then do the draw for that in the next week or so.
The draw for for the Oscilloscope will happen early Feb.
Cheers,
Martin.
-
Is it still okay to enter the power supply giveaway Martin?
If so, here's my humble bench. I do not have the top-notch equipment others do, but I've got the basics (you have to start somewhere, right?).
In the future I would like to acquire an old analog scope :).

Usual mess.

Dear Forum!
First of all, congratulations to froese for winning the power supply! :)
Secondly, allow me to present my attempt to build a variable power supply with reasonable performances (30 V - 4 A). My plan was to make a 4-5 minute video to present it to you live, but I'm having difficulties borrowing a good HD video camera and my Canon can film crap VGA resolution only. Anyway, I wouldn't like to miss the deadline so here we go. In this post I will present the basics only, but those of you who are interested in the details please check out dedicated topic HERE (http://mjlorton.com/forum/index.php?topic=268.0).
The main circuit of the power supply is a J-31 DIY kit from the Polish company named Jabel. I chose to go this way because manufacturing a PCB would've cost me too much both in terms of time and money. The heart of everything is an LM324N - Low Power Quad Op Amp. The transformer is a 24 Volt, roughly 100 VA toroidal one.
A key contribution to this project was made by blankfield who drew the schematic of the improved output stage. The original kit could output only 1 A of current, but mine can easily deliver the 4 A, which is the limit imposed by the transformer. The transistors: one 2N3054 and three 2N3055 on a huge heat sink. Although the heat sink is big, I couldn't keep the power supply passive and quiet; I had to add fans.
The LCD is based on a PIC micro controller (can't remember which one) and it was made by a guy who I met on a Romanian electronics forum. It can measure and display Volts, Amps and Watts. It also has a bar graph thingie which is quite cool. It is powered by a DC step down converter set to 12 V. By the way, this will power the fans too later when I wire them up.
As with the components presented above, I pushed to use quality with the rest as well. For example I swapped all the resistors with ones that have 1% tolerance, I went for bigger capacitors (4700 uF / 63 V), I decided not to use the original bridge rectifier, instead I installed a KBPC2510W and the same applies to the potentiometers which are now 10 turn versions.
One additional feature of my project is its modularity. After failing with the first kit, I decided to connect up everything as modular as possible. This way any main component can be swapped for improvement or repair. Of course, I didn't want to compromise the performance so I did my best when making the connectors. I managed to buy some cool 1-1.3 mm thick pins as well as connectors for cables and I soldered and heatshrinked them all one by one.
OK, that's about it! Having said all this I must admit the project is not finalized yet. I need to work on the case, fix the heat sink to it, install the Vernier type dials on the pots, put protection fuses, find some nicer ON/OFF buttons (main button and output live button separately) and finally I have some more ideas for cable management. But, there you have it. It works and if anybody is interested in building a power supply I can warmly recommend this one.
Many thanks to the forum members who contributed: blankfield, dr_p, Strada916, SeanB, Monkeh, runem, mariush! Only with your help was it possible to get this far and learn so much. A special thank you to our "Hero member" :) and ISO-Tech for motivation!
PS: I won't give up making the video, but in the meantime DesignSpark file and photos attached. And a request to Martin: please let me know if I qualify for the giveaway with everything I put in this post.

I finished my project for the Oscilloscope contest, it's done, finito. It's a battery powered portable Lab PSU and it's called LiPSU :P
The video I made is not my strong point, I didn't realize it's shaky and poor quality. I had no separate microphone to screen capture with audio,
instead I filmed the monitor. Also, the pocket camera I used had no way of refocusing when filming, so had to stop, refocus, continue recording.
I filled the 2GB card 3 times and exchanged 3 sets of new alkaline AA. I hope you guys like it, I've put a lot of effort into this little project.
Overall I'm happy with the way it turned out, it's compact and quite usable. I uploaded an archive with some datasheets, eBay links, Design Spark
project, simulations and some internal pictures: https://d.transfer.ro/LiPSU-transfer_ro-30jan-b487d6.zip

I was trying for the Oscilloscope contest
I tried making a Simply FM Transmitter and was going to expand from there ...
But my 2 month daughter got really sick and spend some time in hospital ...
She is out now but take up all my time and also she is teething now....
Here is what I got

Gents,
Thanks to each and everyone of you that have entered. I'm going to go through them but you all qualify for the draw. If anything happens to be missing I will ask the judges to give you time before the draw.
Judging will take place next week (Paolo and some forum members) and I hope to announce the winner on the 14th of Feb.
Cheers and good luck,
Martin.

Huh... was waiting for 0.3mm DNE wire to arrive (for ferrite based antena). Well, will try next time :)

How long before it arrives...can you post pics and circuit in DesignSpark in the mean time and it will qualify as an entry...

DNE wire arrived today!
In meanwhile screenshot of schematic editing in DesignSpark. My first DesignSpark suprise - there was no speaker component in the library and "model source". I had to create own component.
Started making ferrite based antenna (100:7 wire twists). Paper/plastic based home made coilformer. DesignSpark printed schematic on the table.
Edit, 2x update below.
Updated images and working product :)
Also no longer on breadboard.
First youtube demo. You are going to listen a bit of PR1 (Polish Radio S.A.) program on 225 kHz.

Schematic. Note that device works with 5V-9V range, too. I'm running it from PSU at 6.5V.

Ferrite antenna. To make one you will need DNE 0.3 wire and 6mm-10mm ferrite core. First coil is 100 twists (not sure if
that's the correct english term). Second coil, on top of the first one is only 7 twists. Coilformer made of paper and A4 plastic
cover sheet. Later paper was removed to create a gap, so ferrite core could be moved.

Hi Guys
This is my project for oscilloscope contest. It is Control Panel to emulate keyboard shortcuts in Mach3 software. Mach 3 is popular software to control CNC machine. Communication with the software can be done by using mouse or keyboard shortcuts keys. I never remembered which one are which so i decided to make control panel using Arduino Leonardo.
Very recently i put it all together and ran first test run.
Video of this can be seen there http://youtu.be/sP8AKqnnQFk (http://youtu.be/sP8AKqnnQFk)
Video of CNC engraving the button. http://youtu.be/OhKs9RNlSwM (http://youtu.be/OhKs9RNlSwM)
All buttons are illuminated and "color coded" to distinguish between different functions. So now instead of pressing Alt-R to start the program i just press the start button. Much user friendly.
Hello Hoopoe,

PS: I won't give up making the video...
So, I got a camera, made a 15 minute video and although it's not the best I decided to make it public. :)
I've been having a sore throat for more than two weeks and words came hard, but I thought that some of you might find it interesting to see my project live in action.

Congrats on the Winner
But How does someone win with a power supply when the competition was for a AM or FM Radio ?????
Quoted by "MJLORTON"

SO WTF you picked a person who failed to follow the rules ?????
I am not saying I should win because my children are more important than the competition and you stated clearly stated the rules and alot of people followed the rules as you instructed ... But you are going to punish the people who follow the rules for someone who failed to comply with the rules ????
That is plain Bullshit for anyone who tried really hard to win ...
SHAME ON YOU
-
@TorqueRanger Please read rules carefully:
1) Build an AM or FM radio circuit[...]
or
2) Build a power supply circuit. [...]
Obviously apples and oranges don't compare but this competition wasn't about comparison.
Congratulations for the winner!
