In today's post is a tiny Programmable Waveform Generator module based on the Analog Devices AD9833
This is what I bought:
AD9833 Programmable Microprocessors Sine Square Wave DDS Signal Generator Module http://www.ebay.co.uk/itm/-/381214316569
Here's the AD9833 datasheet:

Wouldn’t a slower clock give you worse resolution? I’m not understanding how going from 25mhz down to only 1mhz increases resolution? It’s usually the other way.
Can the AD9833 be tuned to 1 frequency without programming?
can we change amplitude?
You want a music chip that lets you change amplitude, at the very least. Most will have multiple channels. This chip is for communications. You'll also need a low-pass filter.
SABIAS QUE LOS CHINOS NO LES IMPORTA LA CLIENTELA O AL CONSUMIDOR ,,,SOLO LES IMPORTA ES VENDER UNA SOLA VEZ…..
hey, nice video, can you share with some file when i can know how to generate a sine wave ?
could u make a simple sound card oscilloscope
could you please give me the code of programming AD9833 , I am using pic18F2550 , and I dont know how to get started , thx in advance
so did you make that organ then eventually?
Julian do you get ripped off a lot by the Chinese sellers on Ebay? Like you I used to order a lot of gadgets that were cheap on Ebay and never had many problems until recently but lately it's all been going down hill. Even though Ebay has a lot of hype about having a Money Back Guarantee I found out it's all nonsense and it you don't get the item there is nobody to contact about getting a refund!
I ordered 10 LEDs that were an item called:
"10Pcs DC 9-12V 10W Cool White High Power 800-900LM SMD LED Lamp Flood Light Chip" for $7.61 and $4.00 shipping from a seller called Happydeer88, item # 390876125031 on April 24, 2015.
The item was delivered on May 2 but it only included ONE Led, not 10 as described in the auction.
I know sending only part of the shipment is a common ploy of scammers. When I contact them about sending the rest of my order they always say the same thing, that it was shipped but there is never any tracking number.
Dear customer,
We have sent the rest goods out to you on May 8th, now it’s on the way shipping, you know this is oversea shipping, usually it needs about 2-5 weeks can be arrival, could you please give more patience to wait?
Best regards
Lucy
There doesn't seem to be any Ebay customer service option available to
address this problem, no way to contact anyone or get a refund! It
says to select "Item Not As Described" but then the remedy is to return
the item. However it then says it's been too late and there are no
other options or ways to contact customer service!
If I select "Item Not Received" it takes me to a page to check the package tracking
with no other options there either. If you order several items and
they only ship one you seem to be out of luck with no options.
I'm not sure if Ebay is actually this stupid or they are in on the scam!
I think all Ebay's hype about "Shop on ebay with complete confidence, eBay is here for you" is nothing but a fraud since there doesn't seem to be any way to get any sort of help for this problem.
Do you have any suggestions?
stop showing us your organ!
Sorry but have to say, Hate the new thumbnails. Also am started to get bored with your videos. We seem to of lost your original ethic of buying cheap parts from china and showcasing and demonstrating. Enjoyed the Banggood Scope (as I have been looking at it) but seem to be missing the good old postbag and moved onto projects that only interest a very select group.
Why not just use a DAC straight from the arduino, do you think this sounds better?
anyone on here handy at arduino code ? im in need of some help getting the ref pin to work on my arduino and i think its code related
Very cool little module. Going to check them out. Cheers
Where did you get those 100 won coins?
Loving the new thumbnails! 😀
