I’ve had this kit in a drawer for like 2+ years, but you inspired me to finally put it together. Works as shown, boys and girls.
I learned to solder by building my first kit with a $5 iron I bought at Walmart. Now I use a $10 Dollar iron I got from Amazon. I still have never used a good soldering iron but I do love to look at new irons and one day I will get one. Like you I did the military thing. I did the air Force for 16 years. I planned to do at least 20 but Iraq messed that up. So I have some health problems that prevent me from working which sucks so bad. I live on my VA disability because of Iraq. So it means I usually only get a cheap kit or two a month. I also plan out bigger projects and slowly buy a chip here and a cap there until I can build it. I do have a scope because someone in my life bought it for me which blew my mind "best birthday ever" I knew it was coming for a couple of months but the day it showed up was just great. I was a sheet metal guy in the air Force so electronics came late in my life but I'm so glad I started learning it. I watch a lot of CZcams and read a lot of online articles about electronics. I've read every book about it that my local library has. I learn a ton watching your videos and I just want to say from one vet to another thank you Paul for helping me with the hobby I love.
Mike you are more than welcome. You should have your new meter tomorrow.
Thank you for your service.
I'm 31, got my first dmm 18 months ago to try and fix a TV. When I couldn't understand anything I got obsessed. Since then I've invested well into 5 digits into my home lab. I'm still new with much to learn but have a well paid career and am fortunate to be able to invest into my lab the way I do. I thank my CZcams professors like yourself for bridging some gaps. It's hard to start posting videos but I wanted to show a learning perspective so just started posting videos on my other channel. It's never too late to start. I wish I would've found this passion sooner. Thanks for posting.
Love the stories 👍. I got hooked to electronics in 2nd grade while watching a summer school teacher flying RC planes. I started soldering on my model railroad around 9 y/o. The rest is history.
I’ve been looking for a reason to not switch out of engineering, and I can earnestly say, this account is one of my biggest reasons I haven’t yet. (Granted it’s making staying in ME and not switching to EE much harder). But I want to say thank you for producing such digestible and applicable content.
Hi Paul, I'm watching you from Shetland today (on holiday) but home tomorrow! Good wee kit for those getting into the hobby. I really need to try to learn how to programme pics but they seem quite daunting compared to Arduinos!
It started at yong age by tearing toys apart and see how they worked. A person on a garage reparing coil from motors, transformers had soldering and i had a broken console game pad. He learn how to scrape the trace, solder the cracked joints and wire. On the next day solder pins and more. It was a hard worker at long night and my father allow me to go because he knew i was learning and the man was a good neighborhood.
Then he unleashed my imagination with the 555 IC :P and followed breadboard, soldering iron, analog multimeter.
Good concern about learning from your wisdom.
The component holes on that board look ENORMOUS!!! Surprising that the resistors didn't slip through.
Speaking of Clive. His soldering jig is ideal for jobs like that ... Never seen one for sale either new or second hand. I'm surprised no one on the bay has come up with something like it - anything better than the "helping?" hands. Which are better than nothing - but not by much. Mine is very clumsy and fiddly
When I was in RTC San Diego ('71) didn't get any specialized training for my rate(ET). That came after boot starting with Basic E/E School. The real training in soldering actually was after I was out in the fleet. I seem to recall some of it in Electronics School on Treasure Island but it was just the rudiments needed to work on tube equipment.
You are the second person I know who learned their electronics in the Navy. The other guy served on a sub for a number of years working on the sub's systems. Eventually, he retired back to civilian life and opened up his own electronics repair business.
Thanks for the Post of the counter. Looks like a fun kit now that you have the bugs exterminated. Did the same trip to NTC San Diego, but back in the "60s". Marched over that bridge to the barracks and spent lots of Quality time on the "Grinder" listening to Sousa marching music. All in all, still Love the Navy.
Hey man I’ll buy from your Amazon page. Thanks for uploading great helpful content.
Hey Paul. I finally broke down and bought a real freq counter/generator. It's a "DANIU FY3224S (FY3200S-24M) 24MHz Dual-channel Arbitrary Waveform DDS Function Signal Generator Sine Square Wave Sweep Counter" from Banggood. Looks pretty good, but I've been too sick lately to do much with it. I did buy the kit you are talking about but it was before your store. It never did work right, likely my fault, but couldn't find anything wrong? Oh, and several things have made their way to the high desert in Oregon, for that my eternal thanks. Good kit I might just get one to see if it'll work for me, thanks for the entertainment and life history! ;-)
Really enjoying these videos where you build a kit and just tell stories. This looks like a fun build. Is there any advantage of having a dedicated frequency counter compared to using the one from the multimeter?
I myself learned to solder just by watching videos on youtube and then building lots of kits. My dad was really into electronics when I grew up but somehow he never tried to get me into it which is kinda sad looking back at it. But he kept all his old stuff so when I started a few years back I got all those old parts from the late 70s and early 80s. And he is really amused that I am kinda doing the same thing he did
I just built mine, got it in the mail from China today. The price has gone down, this one cost me 3.50 plus tax so basically 5 bucks free shipping as norm with China. Fun build, I did find an adapter to use on the plug but I think I will be just bogging in a 9 volt hookup as well, to much of a hastle finding the blasted plug deal, then putting it away for use else where when i have finished. Thanks for the Video and 73's from KE0JBL
"Don't go all Kevin spacey them "" F***NG CLASSIC !
That kit looks pretty useful for a guy like me - a hobby electronics tinkerer !
love it
its got a cool floating decimel point, fancy!!! =)
A nice video, but it would have been better if the guy just showed how the project is wired up and what the parts are in the project, still , a nice job. Thanks for sharing .
just got my delivery today for my new build to night its the dso 138 Oscilloscope kit any pointers paul .been watching all your shows and listening to your voice on all shows so much it seems like i know you for long time funny yes ive done a grap load of cheap builds learned a lot from doing them and you your doing an awesome job keep it up. learning a lot form you thank you.
czcams.com/video/UDHAyITL5Nw/video.html
thnks i remember watching it it was one of your first show and it took me about 2.5 hours to check values
i keep for getting to ask you on some boards there are pads on front and back now i have seen components soldered on front and back what is the reason for this does it help for like boards in vibrating or shock proofing it
Is the PIC microcontroller blank until programmed?
Well, you answered the question in the video. I assume a programming interface is available for the PIC.
Can you make these frequency counter kits run on cb and ham?
Recently I've bought the same kit. Like yours, I wondered which of the three pins should I connect for measuring: On the PCB are "-","+" & "in"...which are the correct? Greetings from Argentina!
something that a good multimeter can do for you, easy hahaha but it was a nice review, thanks.
I might interject a hint: measure all components on a meter before installing. It happens pretty rarely, but components can be mis-marked. Had a oscilloscope I built fail the smoke test. Was grateful the blown fuse saved the project. There was one of the diodes marked backwards. And another time a project I was doing for the Canadian Navy was stalled for a while because the orange paint on the resistors was brown.(big difference between 110 ohms and 11Kohms)
I built one of these a few years ago. I used it to check crystals for rock bound QRP transmitters like the Pixie. Seems to me I had to add extra Capacitance to the 22pF caps to keep the oscillator stable for 40M crystals.
Chuck Adams K7QO had this to say on the Chinese kit in 2016. "Photo 40. Two 22pF disc capacitors. If you have a supply of disc caps, do not install these. Put in a 68pF for the top cap and something like a 120-200pF for the lower cap. The 22pF caps work for crystals that are above 10MHz, but may (not) work for lower frequencies. The (Chinese) designer just copied some values somewhere that did not consider lower frequencies that ham radio operators use for experiments."
Hope this helps any one testing 80 and 40 Meter band crystals.
I have this kit what do I need to build and run this kit??
I use 63/37 solder instead of 60/40. It has a faster solidifying time and makes it easier to get a good connection(less likely to make a cold solder joint) But, it's a bit more pricey.
I don't know what it is, but you have read my mind again. I also wants to make a frequency counter but i want a easy way to add a binary counter. So my frequency is 1 second, after 60x60x16 i want to have a signal, then after 60x60x7 i want to start over again. Off-course i can use a PIC or a binary counter. But i want to make something that is really primitive.
I have this kit Oh' yes I am a fan of Big Clive
After the first 5 minutes, skip to about 23:00 unless you want to see the guy soldering. It is like watching grass grow!
Where can I buy this kit?
I have the same unit and another different unit with the yellow button. Both units will NOT read above 16 MHz properly. example, 37.600 MHz displays 15.53xx. Other 37, 38 45 MHz crystals show similar results. They 'divide' by 3-ish and that's what they display. Anyone know the fix?
"... and somebody had to go for counselling." ROFLMAO! 3:16
Them resistors...lol
I built the kit last week - It boots and and then shows a single zero like it should, but any input I feed in displays "62.223" ... sometimes a few decimal points higher..... sometimes lower, but whatever frequency I feed in from my synth, including a 440Hz reference tone, I get the same result. I've no idea how to fault-find on this device. Looks like a dustbin job.
Should have tested your shinny new TS 100 !
70% humidity! I would take that any day. Don't move to S. Florida 😬.
Yeah since the front passed through the humidity has dropped here. Now it is only 94%. We can run in the high 90s for months at a time.
LOL, I bought that kit last year but I can't find it, no way to remember when I stored it, still in parts.
:o(
Somewhere in a bag...somewhere
What ever happened to you "Synth Experiments" series? Also, your Q&A were fun.
No one liked the synth. Q and A will be back.
That sucks about the synth stuff. Its actually a very interesting topic. Would have like to see your take on it. :(
Beside what they claim -not sure whether mine was defective or the way it is- it only measures crystals up to 4mHz.The rest fine.
Hello sir can this test a 32.768Khz crystal on the motherboard can u give me a link to a tester that'works for this crystal or a multimeter thank you
It will work
@@learnelectronics I have found crystals in the kHz range don't test. The small barrel ones with radial leads from watches, etc. I have also found 50MHz crystals don't test. In my experience, this is a 1-49 MHz tester.
lol this kit is only for checking xtal crystals in those small steel cans with 2 legs. you need other type of board to see what you are transmitting on but both kits take same pic chip and you would have to remodel your board to read transmit mode. i have the same board and i use it to check the xtal frequency's so if you are trying to find where you are transmitting dont get this kit
Man if they don't ask about being Dorothy's friend, they ask about preferred foot...
Well, 11 is one more than ten, isn’t it?
Would you be interested in building a kit I designed?
Possibly, email the details to me @ arduino0169@gmail.com
i'm so ocd when comes to components arrangement
I built circuit boards professionally and we definitely had rules for how parts went on boards. Depending on orientation with the top side of the board up parts either read left to right if they were horizontal, or up down if they were vertical. When you look at properly assembled boards that's how they're made. Part of the reason for doing that is so you can QC the boards. When all of the components are in the same way it is easy to spot out ones in the wrong places.
amphibious lol
Laughing at how big all the holes are. All the same size cost cutting
'Chinese just stole it from him'. Quite common. Steal designs, cheap them up, sell them for next to nothing.
Bad work. Look at the orientation of the resistors and the diodes.
You can't complain about the Chinese ripping someone's design off...when you've bought the thing from China for cheap!
Yes I can. That's part of what i do here.
