David Bolling

“David is an exceptional electronics Technologist who goes far beyond the definition of the job. He has multiple years of experience which allows him to draw on various experiences and apply them to the task he is working on. David is self-motivated and hard working. Since electronics is David’s personal passion also, one can see how he enjoys working on complex electrical circuits. I have frequently come to him with malfunctioning boards designed with lead-less components and even BGAs and he has been able to help us solve the problem. He has created small custom hand wired SMD boards to add modifications to boards where they otherwise would not fit. This has saved a lot of time and the expense of creating another board rev prior to testing. David also has a very good understanding of analog electronics which is a rarity these days. His fluency with Multisim has also helped out with his circuit design experimentation as he attempts to come up with new ways to solve old or sometimes very complex problems. In one instance David worked on the ultrasonic caliper sensor to a point where he was designing the full analog front end of the ultrasonic driver and receiver. He found a better way of isolating the receiver front end from the drive signal by designing a custom multi winding transformer which also improved the signal distance in drilling mud. This analog knowledge has also made him an expert in EMI and induction type circuits and he designed a few analog induction based distance measurement circuits also. David also excels at recognizing the functions of circuit designs. At one time we gave him an old high current pulse magnetizer system to debug from 3 decades ago. He not only figured out how it worked but also identified and corrected a design error in the pulse circuit which was causing more than 50% of the existing circuit boards to fail testing. He also created a schematic which no longer existed and applied the new changes along with a new bill of materials with new available parts. This ability of figuring out circuits and creating schematics is particularly unique to David, only a person comfortable with electronics like he is can do something like this. Unfortunately, a couple of years after my internal transfer to another group the entire new technologies research group was dissolved at Conroe when a high end project was canceled due to present market conditions. There was no longer a position for David. It is a huge loss for us because he was helping my group even though he was not reporting to me. We could really use David but my department no longer has the funding to take him on in these present market conditions. I wish him the best of luck at finding a new position. I would like to hire him when the industry conditions return to normal.”
