Bean Bandits Levin 'Globetrotter'

so following up this post I made in another thread

I used my arduino to simulate the frequency (5V square wave) and amplified that with the help of the following circuit


here's a teaser:

will keep connecting the rest of the dash to test illumination and then switch to the 10k fascia.
Last but not least I'll need to dig into the circuit to adjust for the sweep so it'll reflect the rpms properly

here's news (I'll let the pictures speak first)
Before:


After:


some info to judge the picture, both sets of pictures were taken with the exact same settings on my DSLR mounted to a tripod (those interested can click the picture and download the big version incl. meta data). I did this to insure proper comparability between the before and after.
I also need to mention that my bulbs are decades old and were so dim initially that I removed the blue plastic caps to get slightly better results in both cases (again to keep it even for before and after).

I also did a follow up video. Again under same conditions as the first video.
I took a video with the illumination on but the rpm sweep was off, I can only assume it's due to my weak 300mA power supply (needs to be investigated further).

I'll need to order in some electronic parts to simulate and connect the rest of the cluster so this might take some time.

Meanwhile I'll source some new bulbs and try again with the blue caps and try to get a more even illumination. The back of the two fascias are very different



I'm pretty sure I'll get a batch of those done so stay tuned :wave:
