Created an airband bpf in kicad. Not finished. I knew next to nothing going into this. But with the help of some great books and weeks of research I will have revision 1 completed. Not expecting it to be perfect and I am fully aware that one can be purchased for a very low price. But I did this as a learning experience. I will post the results once the components are populated. All smd except for L1 and L2. Some of these photos are just me learning the nanovna and inductance meter. I also tried to prototype this design originally in Manhattan style but quickly learned that was near impossible at this frequency. Thanks for checking it out.

Learned to etch today. I designed a simple 555 timer in kicad, and turned into an etching.

I'm familiar with pcb manufacturers, but i always wanted to try this. I just think they look so cool and it is a good skill to keep in your back pocket.

1. Design circuit in kicad or other electronic design software. Traces should be about 0.5-0.8 mm thickness.

2. Plot your copper layer.

3. Print on transfer paper using a laser printer. (Mirror print)

4. Agitate pcb in ferric chloride until copper etched away.

5. Rinse with water and use nail polish remover to remove the toner.

Haven't drilled holes and added components yet, but I'm pretty stoked how it came out.
