Do you consider making your own probes a hack or not? For example, making a near-field scope probe from paper clip?

To hack or not to hack?

What about when it comes to more expensive equipment, even say $1000 and up? Will you risk voiding a warranty or calibration for functionality?

I love these hacks! I question the logic to hack the cheap gear but this is more about artistry and 'climbing the mountain because it's there' rather than reason (or functionality). I mean, if you are trying to prove a point, then the cheaper the gear the more interesting the hack.

Looks like I do have the VB code. I'll upload it and fix the link on the article, then tell everyone here when it's ready.

I worked with somen years ago on several article that use Excel. Here's one.

Thermistor and DMM Measure Temperature.


The link to the VB code doesn't work but I might have it.

I've seen many ways to measure temperature with a DMM. One uses a bipolat transistor relying on the PN junction. Voltage changes with temperature. You do have to linearize in software. You can do the same with a thermistor. I used to have some code that worked with a 34401A to convert resistance to temperature in a PC.

If you ask around on the LabVIEW or VEE e-mail groups, you can probably get someone to send you their code.

I created a small interface board for my Mitutoyo Caliper (with electronic interface) to convert the signal to connect with a parallel port (LPT) on a PC. I then read the data directly into Excel. It was documented in my book "Excel by Example" Only availabale on Kindle now. I would be more practical to convert it to serial nowadays (I wanted to show how to connect to the parallel port back then).

Very interesting. Reminds me of old elektor days. When I have young engineers work for me, most evening they discusses similar new ideas with me.

Very informative article. I really liked the idea of converting digital DMM into temperature measuring device. Best part about all these ideas is that they can be easily realised with little investment. Looking forward to more such ideas.

Leave it to engineers to reverse engineer and modify their tools.  Very fun article.  Gives me some ideas of making my own modifications.  Thanks!

michigan0 Sang Kim First, 28nm bulk is in volume manufacturing for several years by the major semiconductor companies but not 28nm FDSOI today yet. Why not? Simply because unlike 28nm bulk the LDD(Lightly Doped Drain) to minimize hot carrier generation can't be implemented in 28nm FDSOI. Furthermore, hot carrier reliability becomes worse with scaling, That is the major reason why 28nm FDSOI is not manufacturable today and will not be. Second, how can you suppress the leakage currents from such ultra short 7nm due to the short channel effects? How thin SOI thickness is required to prevent punch-through of un-dopped 7nm FDSOI? Possibly less than 4nm. Depositing such an ultra thin film less then 4nm filum uniformly and reliably over 12" wafers at the manufacturing line is extremely difficult or not even manufacturable. If not manufacturable, the 7nm FDSOI debate is over!Third, what happens when hot carriers are generated near the drain at normal operation of 7nm FDSOI? Electrons go to the positively biased drain with no harm but where the holes to go? The holes can't go to the substrate because of the thin BOX layer. Some holes may become trapped at the BOX layer causing Vt shift. However, the vast majority of holes drift through the the un-dopped SOI channel toward the N+Source,...
