New boards are here!

New boards arrived, with £5 duty/VAT to pay and a stupid £8 Royal Mail handling charge. 

Only one minor issue with one set of boards have a routed slot not routed.

Also some other boards for some power amps to play with. Might start another site with more of my other hobby stuff on and upload some of these projects to that.

Tracking...

of the postal system/courier type. So my package of PCBs from China arrived at Heathrow in the UK on the 18 April, not that long ago. Royal Mail promptly sent this to the wrong place near Birmingham on the 19 April and have not updated the tracking information since, except to say they sent it to the wrong place.

So JLCPCB and supporting services can, in two weeks, produce 55 PCBs, of mixed designs, ship them half way around the world, all in very good time. Yet the Royal Mail in the UK cannot tell the difference between the M1 heading north and the A23 heading south, on an island where England is what, 400 miles long? Well done. *claps hands*

Let's go...

Finally, after quite a break, I have order some new boards. 7 different designs from JLCPCB. Never used them before, but I know people who have and seem happy with them. Plus they are very very cheap for what's on offer. Not sure if I will have to pay import duties as the order was a little expensive.

4 designs are OHDSP boards, uDSP, uCODEC, CoreOne-xCore200-2.0, and DAC-AK4458 boards. 3 designs are something different, all power amplifier designs, two clones of some Silicon Chip amplifiers, and one a "homage" to the old 1980's Yamaha HCA style amplifiers. Just something to play with, no idea if they will work, or be stable, or sound rubbish, with more modern devices. We will see!

Order towards the end of last week and already being shipped which is impressive.

I have also dug out some other bits and pieces that have been waiting for attention. I have an ST TDA7498/TDA7492 PCB design I ordered back in 2017. PCBs have been sitting in boxes since then, plus most parts to test them. Couple of potential issues with the output filters I have spotted before building (component power ratings), but I shall build them up anyway to test. No point letting them go to waste!

Even more boards!

Have put up files for a new simple xmos board (CoreOne-xCORE200-2.0) and an AK4458 based dac (DAC-AK4458). Not committed to release, likely to be a few small mistakes. 

I have been holding on to a few of these design for a long times. I have not had the funds to buy the boards and build them, and keep tweaking the layouts which seems to be never ending. I figure if I just put up the files as I might order them, which I really want to do now!

A small DSP...

A small DSP needs a small CODEC (ADC and DAC) board to go with it. So here it is:

4 Differential Inputs and 8 differential outputs.

Not yet tested... but soon!
