- Well well, instructions would have been helpful. After watching someone else's video it turn out the button accesses a menu on 'Long' press and you can measure a crystal directly using the pins I left underpopulated.
You can pick one up here -

amzn.to/2Hhl0AK (US)

It turns out that 'Likes' and 'Shares' actually help the channel so, if you want to, please click the thumbs up or share the video.
I don't have a Patreon or a donate thingy, I get by fine. That said, if you are mega rich and fancy donating something I would find useful then feel free to check out my Amazon wishlist (No pressure) - www.amazon.co.u...

Love the Lazy Sunday kit builds, could sit for hours with a brew watching them.
I built one of those last year. Fun little kit. Thanks.
learnelectronics I hope you will make more kits.
The spare 22pF capacitor does have a purpose. It should be connected in parallel with one of the two 22pF capacitors near the 9018 transistor to enable measuring lower frequency crystals in the 3 pin female connector you've not installed.
Thanks!
Buy a rework handle :-) you can pick up an 858D (which is much the same as mine) for £20. Cheers for watching - I enjoyed your build.
I have been eyeing them up on ebay, thanks.
We call the variable capacitor a "trimmer capacitor", or just trimmer. Love the vids! Thanks!!
Multicore solder is brilliant - thanks for the tip 😉 looking forward to the led build video.
I kinda hope the LED matrix video is a little way off. I recorded a test yesterday and it was... well quite difficult.
You can probably just put one of those antistatic bags that you must likely have everywhere on the LED display to make it read well on camera. Though adjusting the exposure worked fine.
After the 20 Binary Clock kits are sold, perhaps you could publish the design files (Circuit, Gerbers, BOM) online? Then anyone could make one.
It will all be going up at the same time Steve, all people will be paying for is parts and postage. The schematic, board layout, bill of materials and original Eagle files will be free forever to everyone and I would highly encourage people to make their own. The kit will likely be around £10, hopefully less but I know that kind of cost isn't for everyone. It can be cheaper to source/salvage the components so I would love to see other people make something based off the design.
Great Stuff :D
On your LED 18A issue, could you not multiplex at a high refresh rate so only one LED is ever on at any given time but fast enough to the human eye to appear that all are on?
Slow cookers rule. I love mine to bits.
I use cheapy .7mm mutlicore, (60/40 leaded) think it was $4.50 for a few hundred grams, the flux is just right - on clean boards. I brought myself up as a kid on the cheap tubes of solder that you find in a quid shop or a market. Solder is solder to me, prep and finding the tip that suits you and the job in hand is more important imo.
Is there any chance to get the program code for this frequency counter, so that I can upload it myself into the pic IC????
I've just realised why you have so much trouble holding PCBs and soldering components, then you try to solve it with BluTac and PCB holders, etc.. Straight up first thing at 2:58 you start by installing the capacitors.... No, no, that is WRONG. You should ONLY install the diodes, and solder those. Then ONLY the 1/8W or 1/4W resistors, and solder those. Don't use that silly stand thingy - just flip the PCB and use the flat desk/mat surface to hold the components in position! Then install the next tallest, etc. Look how at 44:36 you are attempting to install the IC holder - that should have been put in before almost every other component! So, your assembly method is all arse-about, and simply by changing that process you can make your own life so much easier!
I'm oddly interested in what you put in the slow cooker now XD
You should sell your binary clocks on eBay. I’ll take one then. I’ve never heard of what you mentioned.
best starting with the resistors and any other low profile component
Qual tipo de circuito pode ser adicionado para ele poder ler uma frequência de um transceptor TX ? RX
I tried mine today. Tried to measure the 32khz crystal on a laptop mb. Stays at zero. I connected to IN and G. My scope reads the signal as 32khz. What could i be doing wrong? Kit was from ali.
I can't for the life of me find the document, but someone sent me one that detailed a mod/extra component you need to add to read lower values. Have a look back in the comments, I am sure it is there. If I find it I will get back to you.
Hello, the same device came to me from AliExpress, but I could not measure the clock crystal 32,768 khz, can you help me Thank you
The crystal tester only really works over 5MHz without modification.
@@IanSlothieRolfe Thank you very much, I am an amateur electronic Let me do some research to modify it.
@@IanSlothieRolfewhat modification is needed? This could explain why it’s not reading my 2.0 crystal
This frequency meter will only work well using a signal conditioning amplifier. There is a Russian video on RUclips: ruclips.net/video/RT71uZ3SB9w/видео.html
The description on yadi.sk/i/fMq_8zIrOsl7Fw
Solder? Stannol Sn62Pb36Ag2 0.5mm, 2.5% flux 3-core F-SW26. It's really effective, but the flux needs to be washed off.
I had a look at Stannol, lots of folks on the EEVBlog forum recommend it. The MG stuff was cheaper per 500g so I went for that.
What is the link for the kit, please?
Sorry, forgot to add that into the description. You can pick one up here - amzn.to/2H5ez0a Ebay bit.ly/2snZGma or AliExpress s.click.aliexpress.com/e/qNrfaYV :-)
It can't measure 40 or 50 megahertz frequency.
I got one off ali express something wrong with the
pic does not even light up waste of money for sure
Here's the instructions dave

The expert himself! Your kit build video did a better job than mine at demonstrating the features, thank you for the link.
No expert here dave, just like yourself facied a little build. another worth while one that has got me out of the you know what a few times is this £15 scope, it will also display frequency. i may do a video about it if i get time. www.banggood.com/Orignal-JYE-Tech-DS0150-15001K-DSO-SHELL-DIY-Digital-Oscilloscope-Kit-With-Housing-p-1093865.html?rmmds=search&cur_warehouse=CN
