Nixie Clock build – the final product

The Nixie Clock build is complete after all the design work... Quite a bit of soldering (avoiding the noxious fumes)... Producing the enclosure (it always takes longer)... And the software (which takes even longer), the final nixie clock build is finished! It ultimately came together quite nicely - here are some of the features: [...]

WiFi biltong box – something different…

Another year is close to its end, with the Christmas and New Year / Festive Season upon us. As the post title suggests, something from a little left field: a WiFI biltong box! There are nonetheless electronic goodies involved - the box has a display, with a temperature and humidity sensor. The display has [...]

uSolaire 180: LED grow lamp completed

As eluded to in a previous post, the next project on the books is an LED grow lamp. I've named it informally as the uSolaire 180... Why a grow lamp? Well: one might think an obvious - not necessarily legal, depending on where one lives - reason, but actually it's because my chili plants [...]

Reflow oven wiring diagram

So on a lazy Saturday afternoon without anything else to do, and to complete the 'build', here is the reflow oven wiring diagram. (Update: it actually took a fair while longer to complete this than intended - work commitments and other projects crying for attention...). Without further ado. Warning/Disclaimer: It should go without saying [...]

Reflow oven: wrap-up

So the oven is now complete. Profile-wise it's not exactly what is recommended per a solder paste datasheet, but as I've come to understand the specified profile is more complicated: time vs. money in manufacture, what's actually required, etc. And results so far are pretty good! This is also evidenced by another, tougher board to [...]

Reflow oven: real board 1

So the stencils for the (first) test boards arrived - yay! The stencils were from OSH Stencils and of the polyimide film type. I had no need to invest in stainless steel versions, and if the polyimide film works for test purposes then all the better! Solder was ChipQuick SMD291AX50T3 Sn63/Pb37 No-Clean T3 solder [...]

Reflow oven: Initial test runs

With the oven now ready to run, it's possible to do some test runs. Yay! Taking the cautious approach - mainly because the stencils haven't yet arrived - this is a first stage of the testing, i.e., simply a number of repeated reflow runs where the temperature is monitored per the thermocouple data from the [...]
