あなたは日本のお金（50円玉）をなんてことに使ってるんだっ!! 許されない行為!!!!
This is like very HQ generator used for driving heat induction or RF stuff. Too fancy for just audio project.
Do ad9850 only generates the wave on positive part of the voltage axis? Or does it can produce the wave either side of the axis ?
will I get volt in negative. is output ac ?
Those are 5 band resistors first 3 bands are digits, 4th band is multiplier and 5th band is tolerance. Red (2), Red (2), Black (0), Silver (x0.01), Brown (1%); thus 220 * .01 = 2.2 ohm at 1% tolerance. And, the 4k7 is Yellow (4), Purple (7), Black (0), Brown (x10), Brown (1%), thus 470 x 10 = 4.7k ohm at 1%.
Tight tolerance resistors (especially those made for military use) are usually coded in 5 band, and a 6th band would be the temperature coefficient.
Hi Julian, I may have missed it somewhere but do you have any more information on that solar controller and also the one it replaced? Are they real PWM controllers? How much no-load current do they take from the battery?
Hi Julian, I must have missed this bit about the bricked FTDI's My gosh, they are shameless in the sales of these counterfeits, even today Ebay is lousy with them. I was assured by Alice11011983 that they could only sell me products that were made in China in response to my question about the lineage of the FT232RL they advertize, they are careful not to put FTDI in the item description. I have complained to Ebay twice in this regard. Can't even get one of the culprits to admit they are selling fakes , but at least gave me a refund for two I acquired to fix two adapters that will not be programmed, won't run some FW flashing software like XLoader.
I am thankful I have an actual FTDI (USB to Ser. purchased in early '12) for use with my FrSky RC gear, in order to program or update one must be able to invert the Tx and Rx. I don't think this can be done with CH340. Can you name a serial to USB adapter chip that can be modified like FT_Prog can do the FTDI? Thanks, sorry for the long ramble & btw ,…love your stuff mate. Ps the going rate a Digikey is $6.50 for a real one. So I am got a cart going there:-)
do not throw out the bricked fdi chips you can unbrick them i have
regards john
In 30 to 50 words…give or take, advise all what this unit does or enables one to do. When that's done, this will become a superb overview, as opposed to now being very good.
Awesome video Julian! Bit slow on watching it, but finally 🙂 Cant wait for your summer projects! Keep up the great work!
For a five band resistor the first three bands are the "digits" the third the multiplier, and the last the tolerance. The only difference between a four and five band resistor is the number of significant digits the Ohms are recorded to. The last band is still the tolerance.
I call the language in that "manual" "Chinglish".
