240: Belgian Waffles

Jasmine Brackett (@asiwatch) spoke with us about @Tindie’s electronics marketplace, this year’s Hackaday Prize, and tips for wearable electronics. If you want to buy on Tindie, check out their homepage tindie.com. If you want to sell, that is straightforward too: tindie.com/about/sell.   There is an Embedded contest for the Tindie Blinky LED badge, a nifty little learn to solder kit. Contest ends April 20, 2018 (midnight UTC). You are to send a number to us using the contact link. Closest one wins. One number per person. You can also get these badges at the Dublin Hackaday Unconference (April 7, 2018, Dublin, Ireland) and at meetups where Jasmine is a presenter. Thank you to Ben Hencke for some good questions. He talked about his Tindie store with us on 220: Cascading Waterfall of Lights. Jasmine mentioned the RC2014, homebrew z80 computer kit. Both Tindie and Hackaday are owned by Supplyframe. Finally, we talked to Emile Petrone when Tindie was a fairly new thing on 72: This is My NASA Phone.
