Don't throw your inaccurate clock away! Use RX8025 to turn it to super accurate.
Quartz clocks usually use a 32.768KHz cylindrical quartz crystal which has a typical 20ppm error tolerance, this can produce a daily error by seconds as calculated below:
24*60*60*20/1e-6 = 1.728 seconds, monthly: 1.728*30 = 51.8 seconds, nearly a minute.
However RX8025, the Epson Real Time Clock chip, typical accuracy is at 5ppm, calculated as:
24*60*60*5/1e-6 = 0.432 second/day, that's only 12.96 second/month.
I bought the chip from Aliexpress, only 50 cents each, at my test, it can reach as high accuracy as half the specs, which is about 6 seconds per month!
I can't stop updating all my other clocks in my home.

DIY a laser dot sight for Crosman 1377 pellet gun
zhlédnutí 1,4KPřed 3 lety
I use an eBay 1mw red dot laser module and other most random stuff from my tool box, to make a laser sight for my Crosman 1377 American Classic pellet gun. It works once adjusted carefully. Pros: easy to attach and remove, just need to clip to the barrel and stays steady. Cons: a little bit pain to adjust.

In this clip I will show you how I change the output power from A4988 on a CNC Shield, to DVD step motor writing machine. I also added heatsink to motor and hope helps anyway.
Writing machine - Cool idea to make pen holder and way to level printing surface

In my last video, the writing robot is a prototype and being put together by hot glue. Now I assembled it , with a better idea of the pen holder and working surface board. With level calibrated once so will print without changing.

A drawing robot build from cd-rom motors and Arduino. Using 3 step motors, Ardiono UNO and CNC shield. It is easy and not cost too much when using CNC shield A4988 step motor driver. For better performance, you can swap A4988 with TMC2209 ,and can easily plug to CNC shield without altering anything. This is a prototype to prove the working concept, want to test with inkscape to generate the gco...
DIY - Turn your screw nut to a mini pinion gear puller
zhlédnutí 111KPřed 3 lety
I came across the idea to make a puller from a M12 nut and a M6 screw, to get some pinion gears off my motors. M12 is the biggest one that I can find in my tool box, but Ideally I should have used a bigger one in order to deal with larger gears. Hope you will find this helpful.

I have assembled a music Tesla coil from the kit, it plays music very well. Please noted that the heat sinks come with the kit are too small so the transistor and MOSFET will get overheat easily. I have changed/added larger ones to make it work at normal heat for quite longer time. This clip is about 12 minutes long playing 5 songs.

VOX (Voice Activated) recording RTL SDR audio with Audacity

It is boring to wait for skipping the silence when monitoring a radio signal, and also you may not want to miss the communications while you are away from your desk. I set this up to record the radio audio which can skip the silence. Virtual Audio Cable: vb-audio.com/Cable/ Audacity: www.audacityteam.org/ If this helps and you like it, please subscribe.

Ещё проще: два стула две железных пластины под шестерёнку и дюбелем по оси шестерёнка сама слетает
Идея не плохая,но очень все затянуто
Painful to watch but it works good.
ALGUÉM SABE ME INFORMAR SE A MARCA DESSES TIPO MOTOR JHONSON E BOA?
Hey guys! I see it works with Wide mode, and it works, but the sound icon is turned off so its literally muted the system and it cannot be undone, only if i turn off the demodulator. What causes this?
Вещь!
Yes that’s a drill bit
Great idea, thanks for doing the video.
dump video
A specific guide - thanks
This set up will only decode class 1 clear Tetra DMO. All the EMS Police, Fire and Ambulance use Tetra TMO using the TEA2 encryption algorithm which is extremely secure with all the authentication protocols in place. It is the most secure out of the 4 TEAs.
Столько трудов и все бестолку 😊 попробу снять шестернь от Bosch 10.8 с зазором 1 мм, этот 1 мм от гайки порвет сразу.
This is amazing. The software side alone must have taken forever.
Hiii, do you know if i can upgrade the motor? I was thinking in putting a 540 motor, would it fit?
Hey by any change do you know if the motor of this specific model can be upraded? I have one and was thinking on putting a 540 motor in it? Would it fit?
It can be upgraded but definitely can't fit a 540. 370 is the natural motor size, and it seems like a 380 can be fitted if you trim some plastic away.
Hello. I see that it decodes with voice, but with net info I don't get a call ID so I don't hear any voice.
hello sir. are you in still same situation?
*Awesome!*
Who in the fuck can diy this?!
Man, a plastic gears don't needs a tool to remove the problem is with metal gears
Sir I cannot open page rtl-sdr-ru, page seems offline. Can you upload Tetra plugin somewhere else ? Thank you
Мужик ты супер, быстро, удобно, со всего подручного!!! 👏👍
Dude, how can I be the man when you are the man. I was preparing to slice my wrists and do push-ups in saltwater until I ran across your "so simple it's silly" pinion puller.
Reading your comments I almost fell of my chair. . 🤣 😂.. 🤣 😂.. 🤣 😂.. thank you for making my day . .
Excellence,👏
Thank you very much!
Первое сверление надо делать на сквозь гайки диаметром вала. потом сверление под резьбу.
Проще высверлить с торца винта отверстие по диаметру вала, вставить отрезок вала и свободный конец зашлифовать, что бы потоньше был.по моему так быстрее получится.
Это вообще хорошая тема - мелкий съемник из гайки, особенно если, как у меня, магазин метизов в соседнем доме😀 Я при замене шестерни шуруповерта обошелся паяльной станцией и отверткой, но вот эту идеою вполне можно реализовать на будущее и места он много не занимает.
The best diy I've ever seen, , 👍👍
Задумка то хорошая)) (хотя эта идея не нова). А вот воплощение- это что то с чем то.... Для начала все же надо было тиски прикрутить..
I really do not know but.... i am still waiting for real scanner for tetra and other digetal radio to bay......
Subscribed good 👍 I have tamtech buggy
Can you tell me the ballpark total cost to set this up the exact same way you have it set up. Cheers for now.
Thank you for the video!!! I just made one and it works GREAT!!!! 👍
Thanks for this... But I ended up drilling and welding a No. 8 nut on top instead of making the threads
I like diy stuffs like this. The bore sighters i got are pretty accurate, at least the dot stays where it should be. I attached the bore sighter on my other airgun's barrel using 3d printed clamps, the offset distance between laser dot and bore is less than 20mm. Now I'm gonna do the same on crosman 1322, i can't use any clamp but your paper clip idea inspired me. Thanks!
Is it possible to listen something with this in sweden?
Haw can i get ahold of you in regards to setting up this exact same thing foe someone. Whatever fees are involved of course will be taken care of. If your interested in taking on the project.
good evening sir i tried this solution but it no demodulator block is appearing after adding the magic line into the plugins.xml pls help regards
I've got some of those laser diodes somewhere. I've got a weekend project now!
You gotta make sure your diodes can be adjusted. Those diodes laser dot aren't usually straight.
this is very inspiring me, thank you

Great job But in the cordless screw driver like makita or Dewalt the space between gear bottom and the motor are less than 1 mm can u please guide to to remove it ?I made one like yours but due to thickness its bend immediately
I freakin' love this! Do you sell these? I would love to make one myself but am currently awaiting hand surgery and lacking the dexterity. Things like this are functional fits of art. I love to support those creative individuals over greedy faceless corporations.

@senior zasader If you need it, I would give it to you and you just have to pay the shipping. Let me know you address and I can ask for how much shipping cost.
