Recently my son-in-law got a tip that the Creality company had a nice set offer for the LD-002R resin printer. That set would include the LD-002R resin printer and the UW-01 washing and curing unit for a very reasonable price.

Years ago my childeren build a few crystal radio kit from Chris Dorna PE1DZX which he sold through his website. When Chhris stopped making these kits, he let that website expire to be lost for ever. Recently I was contacted by a ham who wanted to build these radio's and still had the kit building instructions in PDF. I asked Chris if he was ok with it that I shared these PDF's and hosted them on my website. Chris was ok with that so from now on the kit building instructions can be downloaded here.
Big credits to Chris.

Fixed those, ordered a "small" batch, which came in last Saturday. Build two for testing.
Now they seem to work up to 1.2GHz (good enough for the hobby).
