The Trilife learn-to-solder board is getting jumpers for those times the LED goes in backwards. In Oshpark purple.
Jan. 29 update: Got 3 boards in the mail. The jumper idea works, if you solder the LED backwards–no need to remove. About 5% of the students do this.
But, it turns out we have to move the attachment holes a little. Good thing the Oshpark boards are so inexpensive.
