Re: Arduino 4116 Dram tester with an extrenal help.
Hello all.
This is the final design for my Arduino 4116 Dynamic Ram tester. At least for this version. I can’t wait for my first prototype boards to came and start the testing. After that and if all go smoothly i start the printing for this version. 7~12 dc volt barrel jack fitted in this version to power up the board from external power supply and not only through the Arduino usb, plus i add some protection for the Arduino

Step up to red alert. Sir, are you absolutely sure? It does mean changing the bulb
Looking forward to summer later in the year.

Re: Arduino 4116 Dram tester with an extrenal help.
The prototype pcb's has not yet arrived, but i decided to do some changes for the final version. I reduced the board size. From 12cm x 11cm it was, it came to be a little less than 10cm x 10cm. This is because the cost of its construction is significantly reduced, but also for reasons of space saving.

Almost done!
I am waiting some more components to arrive.

There is a manual available and some videos. Looks promising...

Seems to be a really great tester

Re: Arduino 4116 Dram tester with an extrenal help.
There was some errors in the prototype PCB. I did some emergency cable jumpers to solve the problem. Now it is ready and 100% in working order. Sadly I need to order some new pcb’s for the final test. This tester work also with 5 volts, through the Arduino usb plug. This future make it a bit portable with a power bank.

Ahh, bodge/mod wires are normal for a first version. So don’t worry about it
It’s working, that’s the cool bit
