Creating a Walkie-Talkie with generic 433MHz RF Modules!
video description
JLCPCB recommends using EasyEDA for design, but when ordering components from the LCSC Assembly, the minimum quantities are too high for a simple prototype, the search engine is really poorly designed (many unrelated items) and problems accumulate.
Any tips for the successful begginer use of EasyEDA + JLCPCB?
Thanks in advance!

Acceptable? I think there is a long way before u can call that signal acceptable: ) But its a start: ) keep up the great job. Love ur vids: )
I have learnt so much from your videos already and i am continuing to school myself following your experiments: ) some are really great. so much so i have replicated them. But yeah, every week i get smarter and smarter about electronics and that is all thanks to you! cheers! :)

Those eBay receivers are notoriously bad. I have around 5 from buying the transmitters and I couldn't receive a good signal at 1m let alone 15m. Significant data loss. After buying a superheterodyne receiver, I've discovered a range I've not been able to exhaust yet. Then, I made a moxon antenna with my 3D printer and found a range that pierces all the walls in my admittedly small house.

Is it possible to control volume of a speaker that only has analogue potentiometer volume control with a remote and arduino? I know you did this with a digital volume controlled speaker system but is it also possible with an analogue volume controlled one? Thanks in advance: )

While I can buy a ridiculously cheap chinese 5km dual band vhf uhf handy talky with digital encoding encryption for communicating between convoy cars, I am sure this DIY video will be proven useful when nobody can sell HT or WT. after the aftermath.

i would like to see how to build a simple Morse code transceiver to secretly talk to people with the same transceiver
enclosed in an Altoids can
with sensory tapper that is not audible
with simple button
with 9v battery

I leaned that maybe it's cheaper to pull apart a cheap commercial walkie talkie and check it's configuration than it is to try and start from scratch, lol. Great effort though, keeping with the only know if you give it a go tradition.

I've just builded my own automatic greenhouse based on the Arduino with Solarpower, Sensors, Waterpump and vetilation a few years ago.
The only missing Thing in my Setup is the LoRa-Wan that i now had to have.
Great Scott

interesting project. 15 M (50ft) is a respectable range without a power amp for the transmitter or real front end on the receiver. Keep working on it.

I have a couple of questions! Why a triangle wave and not a square wave? RC low pass vs LC, does an LC have a better cut off frequency? Thank you: )
