![]() ![]() – that would show the letters as you transmit them out. Also adding in an audio oscillator / switch & plug to insert a key on the oscillator – then feed the output to the Arduino would immediately mean this kit could be used as a practice oscillator too. The location of the pins for the display / reset switch and audio OUT should be on the other side of the board. That solved the issue, and I have already corrected the fault for the next batch of boards.Ģ further observations of the boards & the project as a whole have highlighted 2 further improvements to the project. ![]() I did fix this by attaching a wire to ground from one of the caps. But the 2nd and more serious issue is I forgot to ground 2 caps. That is an easy fix for the next version. The first issue was sitting the capacitors a bit too close to the LM567 IC. I did make 2 small errors on these boards. All white and exactly how I laid them out. I also wanted to box the project, so my rationale was to find a box first to work out the physical dimensions of the finished project.Īs with the Vero Version – I created a layout that would fit on top of the UNO.Īfter submitting the design, and waiting a week I managed to get hold of 3 boards. This was my very first attempt at creating a PCB, so nerves were a wee bit on the tense side. ![]()
