Hi,
I just about to finish my version of hardware for the OSPID.
I don’t have much money, and living in Brazil can make the costs rises when buying things from other countries.
I can import some pieces, but, if the cost of booth the item and the shipping cote exceeds U$50.00, I’ll have to give 60% of it to the Brazil’s custom clearance service. So, if i import something costing U$51.00, I’ll pay U$ 30.10 to the Brazil’s Custon clearance service, what results in a total of U$81.00.
It can be frustrating, or Am I wrong?
So, instead buying the OSPID from RocketScream, I bought an arduino uno, a max 31885 shield, a Bluetooth shield, a ic2 eeprom a LCD shield, all from dx and ebay.
I Changed a little bit the code on OSPID firmware and now I have my custom version of OSPID.
It works well, and i use the OSPID frontend remotely with my computer.
Also it have another relay out (to cooler the oven i use to roast coffee when the input goes higher than setpoint)
Here are some photos of it:
