Do I need more test equipment?

Yes, go get yourself at least one of those EUR7 Logic Analyzers from Ali / Ebay / China, and use it with Sigrok / Pulseview. I also have an oscilloscope, but I use my logic analyzer more with debugging microcontroller projects. It is both a small gadget that fits easily next to a breadboard, and the PC interface with mouse works quite well in Sigrok. For an oscilloscope the the buttons and rotary encoders are an important part of the user experience, but for a LA, the mouse, keyboard and a PC monitor works quite nice. I also find a LA more convenient because you can work easily with "Dupont" wires on a breadboard instead of the unwieldy big oscilloscope probes.
But I also agree with the others, don't buy equipment too quickly. You will probably know it quite soon when you will need any of the more specialized things.
And you can also make simple yet useful things yourself. One of the simple things I made is an ULN2803 with 8 resistors and 8 LED's. It lets me keep track of a bunch of digital signals on a breadboard visually without loading the signals too much.

Cool, thanks all for the info.
The first processor I ever played with was something like to 8085, an 8-bit 40-pin micro-controller that had ROM chip you erase with UV light
Today I bought, a bunch of heat shrink pieces and a cheap mini PC.
Time to work on my project, sending commands from a web site to python script to rpi than wirelessly to an arduino controlled mecanum wheeled vehicle

One for V
One for A
It is essential for me anyhow ::)

A power supply with good internal metering is much nicer as it doesn't need extra bench space and doesn't need an external DMM. At some point I was contemplating buying more DMMs to measure power supply outputs but then it dawned to me getting a power supply with good internal metering made much more sense.

I couldn't agree more. These come in handy with Arduino and other digital projects. You can't argue with the cost, and now you that have a mini PC on your desk anyhow it makes even more sense.
