Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.

Awesome! Their site is all 404 though. 🙁
Looks like it is up now. 🙂 http://www.ospid.com/
A really nice project! It is good to see they are using the relatively new MAX31855KASA+ part instead of the older MAX6674. But unfortunately I have to (as usual) complain about the unit price/availability of Maxim parts. Around eight bucks for this thing! (At post-time I see Mouser has a bunch though – but Only at Mouser – per Octopart).
To be fair; mixed-signal IC’s like the MAX31855KASA+ are expensive to design and produce, and the take-up has a relatively narrow market.
How long until we see Chinese clones of this design on ebaY? If they do show up, is this a good thing or a bad thing? (opinions?)
How does "open-source" hardware and software licenses protect the developers from use/misuse of this thing from the corrupt and venomous Trial Lawyers in (e.g.) the U.S…? Remember, PID controllers like this typically target mains-powered applications (death possible).
The 10A relay board is nice, but if you want to use this with something like a reflow rig, remember that cold heater element current can be a Lot higher compared with when the elements are hot (but controlling this is what PID thing is all about). For a "hackable" device, I would recommend relays (or SSRs) with a much higher rating – for when your software goes wrong during development. Just to be safe.
Oh yes, about the price… $85 USD; not too bad as long as it includes the enclosure. Keep in-mind this is a start-up. I would like to see options for bare boards only though. You can get Chinese PID controllers with LED 7-segment displays (Industry standard PV and SV) for around $30 USD on ebaY (yeah, like the very dubious thing from Sure Electronics). But YMMV (big-time)…
Pretty nice! I just preoredered one…
