When I made the PCB for the stand-alone inductance meter, I erroneously used a SSOP footprint for the microcontroller (instead of the desired SOIC). The PIC is available in a SSOP package (PIC16F1963-I/SS instead of PIC16F1936-I/SO) but I didn’t have any at hand so I simply made a new board with a SOIC footprint.
Apart from the footprint, the SSOP board is identical to what I’ve finally used and is fully functional. If anyone is interested I’m happy to give it away for free – first come, first served.
By the way, I’m building a second inductance meter for my father who has asked me if he could get one, too. It’s technically identical but this time the 3D-printer had orange PLA in it so I used just that.
By pure coincident, the color just about matches the newer Agilent / Keysight multimeters 😉
do you still have it? i want it 😀
Hi Dacin
Sorry, the PCB has already been shipped to India. But thanks for your interest. Maybe next time 😉

Can you measure an unknown capacitance using this meter? I am developing a sensor that uses capacitance as the measurement variable. I need to measure the change in capacitance caused by the sensor. Thank you for your reply in anticipation.
Hi Krishna. This should absolutely work – I just haven’t done it. The capacitance and inductance are in series so you can also measure capacitance, you just need to slightly change the software. The reason why I haven’t done it is that a regular DMM can measure capacitance so I didn’t need to build this functionality myself.
Hi
I actaully impresed most of your pcb freeze job and equipments you have. Unfortunatly we are not able to find or power to pay for them although having a good job and salary compared to the country economi. Thats sad because me and most of my friends are keep trying to build their own power supplies , oscilloscopes , signal generators etc rather than spending time for R&D projects. It feels like tring to build a skyscrapers without basic tools.
