"it" ... "yourself" (yes, I phrased it that way deliberately). I have many circuit diagrams and assembly drawings. I also have service manuals for older Keysight bench power supplies with detailed circuit diagrams and measurement descriptions. I've repaired such devices. In analog times, that would have been somewhat cheaper, but his question shows that he is looking for a microcontroller-controlled laboratory power supply. That's not so simple. His question also reveals that he's not particularly knowledgeable about electronics. Hmm, how can we help him? With a good recommendation. I think it would be best for him if he bought one.https://community.element14.com/technologies/power-management/f/forum/56962/triple-output-bench-top-power-supply---any-requests/235687Wed, 20 May 2026 16:40:00 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:a7e49798-18f0-49d6-9a54-3c71bc00ba9emichaelkellettIt will be a lot of work to match the specs of that one with a home brew !

Due to lack of time, I postponed it and am now using the Keysight E36313A. https://www.keysight.com/us/en/product/E36313A/160w-triple-output-power-supply-6v-10a-2x-25v-2a.htmlhttps://community.element14.com/technologies/power-management/f/forum/56962/triple-output-bench-top-power-supply---any-requests/235679Wed, 20 May 2026 14:31:00 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:f20d57c1-9d93-4a69-ab29-8b4051b0ffa9dougwI have a triple output supply that I use extensively. It has one high current output but that output only goes to 6V. The two 30V outputs only go to 2A. The only combination I miss is an output capable of 24V at 3A. (My supply can do this by using 2 outputs in parallel) but then I only have 2 outputs. It would be nice to have a USB output that monitors current or can limit current.https://community.element14.com/technologies/power-management/f/forum/56962/triple-output-bench-top-power-supply---any-requests/235670Wed, 20 May 2026 08:52:00 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:f434a2ec-a37b-4d12-8c7e-5213a733e7b6michaelkellettI have two preferred bench power supplies: AimTTi QL564TP, Linear supply, 2 main outputs, switchable ranges 0-25V, 4A and 0-56V, 2A, full LAN control. Used almost all the time, there are few days when it isn't switched on. AimTTi MX180TP also with full LAN control Used less often but good when higher power is needed. Both of these supplies are quite easy to use under manual control and easy to programme via Ethernet or serial port. The metering (especially on the QL564) is quite accurate. The ergonomics could be a little better on both supplies - a rotary control per channel would be good and the QL564 would benefit from a better display. I have other supplies (many) for more specialised things. When you say high performance I wonder what you actually mean - putting everything in one box would be possible but absurdly expensive. Perhaps you could explain the idea behind your project. Just for fun this is what I would like: +/-60V @ 10A full 4 quadrant operation , noise less than 0.5mV p-p 20MHz bandwidth, settling time 10ks/s (Effectively 3 high power source meters in one box) Price under £10k ☺ MKhttps://community.element14.com/technologies/power-management/f/forum/56962/triple-output-bench-top-power-supply---any-requestsWed, 20 May 2026 07:28:00 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:a8e6946e-26d6-4f6c-826b-61828fe9dab6MagnethiccHi Everyone, I will be designing a high performance triple-output bench power supply and I was wondering if any of you have any information regarding your current benchtop power supply: 1. what do you like about it? 2. what do you don't like about it? 3. what kind of features is missing as of today and wish were available? feel free to go nuts, any help is greatly appreciated!https://community.element14.com/technologies/power-management/b/blog/posts/a-modeling-study-predicts-that-solar-farms-could-produce-rainfallFri, 24 Apr 2026 14:18:00 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:631d0452-08c9-464b-859a-50d1589a5ee4CatwellA solar farm. (Image Credit: TheOtherKev/ pixabay ) Is that bad? In the UAE, where water is harder to come by than oil, cloud seeding or desalination plants produce freshwater for everyone living there. Now, a 2024 modeling study says huge solar farms could theoretically impact the weather. In the simulations, dark solar panels absorbed sunlight and warmed the air above them. This may create stronger updrafts that lead to cloud formation and rainfall if there is sufficient moisture. A 2020 study looked into what happens if solar farms took up over 300,000 miles 2 in the Sahara Desert. The team determined solar farms of that size have the risk of making more rain fall and allowing plants to grow. However, that also means it would have a significant effect on the atmospheric circulation. As a consequence, tropical rain belts have the potential to move further north, affecting the Amazon. The 2024 modeling study team tested whether weather patterns would be changed by real-world-sized solar farms. They used a sophisticated climate model developed by the U.S. National Center for Atmospheric Research, which takes land surface changes into consideration. Their simulations represented solar farms as dark surfaces that soaked up 95% of the sun’s energy. Once the solar farms were larger than 9 miles 2 , the extra heat that the panels absorbed led to stronger convection, which forms clouds. Even then, atmospheric moisture must be present. The simulations revealed that the Persian Gulf’s humid, high-altitude winds fit that requirement. Given favorable conditions, the model determined that a 12 mile 2 solar farm may raise rainfall by almost 600,000 meters 3 . It’s worth noting that the solar panels in the simulation had darker surfaces than those produced by manufacturers. The researchers hope to test this concept in real-world settings. For example, China and other places have sufficiently-sized solar farms that could work for those tests. Installing them in specific areas with small adjustments, like darkening the panels and planting drought-resistant vegetation, could replicate the effects in the model. In addition, the team is validating the model against field data from solar farms to improve the simulations. They hope that other regions will notice the rainmaking potential and build more solar farms. Have a story tip?

(Image Credit: Deep Fission ) Nuclear power is becoming more complex and costly, and one startup wants to address that by burying reactors a mile deep underground. That’s why Elizabeth Muller and her father, physicist Richard Muller, founded Deep Fission . Rather than using large above-ground structures to contain each reactor, they hope the Earth can make it safer, cheaper, and easier to deploy. Deep Fission uses modern drilling techniques from the oil, gas, and geothermal industries to drill a mile-deep, 30” diameter cased borehole. The company then lowers a pressurized water reactor into each hole, producing 30 megawatts thermal to create steam. That steam is carried through pipes to the surface, where it generates up to 10-15 megawatts of electric power. By putting the reactors underground, Deep Fission says it can keep them away from weather hazards while reducing the physical footprint. The project also promises lower costs when it becomes fully operational. According to its estimates , expenses could shrink by up to 80% compared to traditional nuclear plants, with construction taking six months to complete. It also hopes to reach $50 to $70 per megawatt hour. Even the Department of Energy has noticed Deep Fission. In August 2025, the DoE selected the startup as one of ten firms for its Reactor Pilot Program, which fast-tracks an evaluation of new, compact reactors designed for simpler construction. Although the other reactors have something new going on, they all stick to the above-ground design. Construction progress of an underground nuclear reactor site. (Image Credit: Deep Fission ) To date, Deep Fission has collected $122 million in funding, including a recent round that values the company at $1 billion. While Elizabeth owns a 19% share, Richard controls 10%, and Joe Lonsdale, Palantir cofounder, holds an 8% stake through his 8VC firm. Sometime this year, they will sell equity to help fund research and development. This also includes investing $84 million in a test reactor in hopes of reaching criticality---a self-sustaining nuclear reactor. Although the White House Administration set a July 4 th target for these new reactors to achieve criticality, the Mullers haven’t committed to that timeline. If they can obtain a license from the Nuclear Regulatory Commission, Deep Fission aims to begin commercial power sales by 2027. This puts them ahead of other startups, such as Aalo Atomics, Oklo, Valar Atomis, and Kairos Power, funded by the DoE. Drilling the first test 30”-diameter borehole is taking place in Parsons, Kansas, within the 14,000-acre Great Plains Industrial Park. Deep Fission’s plan is to insert a reactor canister holding four conventional fuel assemblies enriched to 5% uranium. They will then trigger it remotely by withdrawing neutron-absorbing control rods, which accelerates the nuclear chain reaction. Keeping the radioactive site at the bottom ensures that the steam moving to the surface remains contamination-free. With the closed-loop system, condensed steam returns underground, restricting water use. Elizabeth and Richard believe that burying the nuclear reactors underground may result in safer, simpler, and cheaper nuclear power. After all, the surrounding rock works like a barrier that contains the reactor and makes us less reliant on large, expensive above ground power plants. Plus, it uses drilling methods that speed up the construction process. Even though the approach still has major engineering and regulatory challenges, reactor deployment may become less expensive.
