I only occasionally swap resistors or add leds in the 1206, 0805 range. So not very often. Hot air station for me doesn’t make sense cost wise. I’m okay with an iron, but a good magnifying head piece with lights built in might be my next purchase.
If I built drivers, then a hot air station might be worth the expense.
I have a helluf a time getting the parts to stay in place with hot air, even slowing the air flow rate way down. Is there a trick I am missing? Maybe I need to mount the board differently and hold the parts in place somehow. But, with a bunch of parts that is not likely to happen…
added info about NarsilM
Prices reduced slightly for OTSM and LDO due to quantity discount and a cheaper tantal cap with same specs
if you got Bistro HD OTSM message me to get this new OTSM part prices and a paypal refund as the original pricing was too high
as Oshpark was so kind and did more 46mm with correct solder mask I refunded the 2/3 costs on this size
to show the price difference from flintrocks suggested tantal cap to another brand with identical specs
prices does not include 19% import tax
Pleasant surprise but if given the choice I’d rather you had kept it and had a as thanks for the time and work on these drivers. That said, I respect the decision and would do the same in a similar situation. You have my respect and appreciation and I look forward to the possibility of future offerings.
good news Kaidomain delivered 10 short and 10 long 6mm diameter springs today
here a pic, why 15mm Bistro OTSM is a bad idea as the driver has no C2, R1 and R2 pad
R1 and R2 are soldered together with the red wire in the middle and soldered under the Attiny25V to pin4 of the MCU
C2 sits on the indicator LED resistor with cut trace on one end
solder bridge from diode to C2
looks a bit messy as I had also to change C1 from 10 to 1uF
and my 38.5mm Cuoroi LDO piggyback 2S/3P
driver needs to be cleaned from solder paste and flux residue which got there getting it on the LDO legs and C2 soldered
today springs came from Kaidomain, so I soldered them for the people who dont think they can do it, it adds 2.5$ shipping costs and 0.5$ for soldering
on the 17mm driver with long springs its a tight fit
so did the Bistro drivers I assembled so far
and the Narsil v1.4
I had 2 drivers where in 2S operation one AMC7135 had this parasitic drain issue when the driver is in sleep mode
they are oficially not build for 8.4V
still waiting on boards from Oshpark that I have ordered later as more were requested than originaly planned
I printed the shiping addresses with information which drivers and export declaration
then used residue tape to fix the drivers where they belong
also wrote on the tape the drivers specs
