“I used both female and male headers. As described the female header was very simple, whereas the male header needed more care. Nonetheless both work fine - and it saved me from soldering!”
“I was wondering if they could extend the concept to other "header" configurations. Or actually to headerless configurations.
So far I've foregone on actual soldering.
Perhaps someone could create a soldering exercise kit.”
“I didn't trust my soldering skills so this was the ideal solution. I found trying to use the jig on a tabletop (as suggested) was too 'bouncy' but putting the jig on a cutting mat then laying that on a concrete tile on the patio gave a much firmer base on which to hammer.”
