Ep101: Lasering and Milling Absolutely Everything
Play • 42 min

Hackaday editors Mike Szczys and Elliot Williams discuss our favorite hacks of the past week. We accidentally chose a theme, as most of the projects use lasers and are about machining work. We lead off with a really powerful laser that can directly etch circuit boards, only to be later outdone by an even more powerful laser using a chemistry trick to etch glass. We look at how to mix up your own rocket motors, bootstrap your own laser tag, and go down the rabbit hole of building tools for embedded development. The episode wraps up as we discuss what exactly NVMe is and where hardware hacking might take it.

I moved to Octopus recently and had been putting it off for ages, but I kicked myself for not doing it sooner, as it’s literally a 5 minute job to give them your details. Click here: https://share.octopus.energy/free-puma-452 On today’s podcast: * Aptera Closes $4M Series A Round and Takes a Quarter-Billion in Orders * Ultium Cells Celebrates Completion of Steel Building Structure * Peugeot Beats Renault In France * Virginia to become the next zero-emission vehicle state * VW ID.4 At US Dealers In March Show #999 Good morning, good afternoon and good evening wherever you are in the world, welcome to EV News Daily for Saturday 20th February. It’s Martyn Lee here and I go through every EV story so you don't have to. Thank you to MYEV.com for helping make this show, they’ve built the first marketplace specifically for Electric Vehicles. It’s a totally free marketplace that simplifies the buying and selling process, and help you learn about EVs along the way too. APTERA CLOSES $4M SERIES A ROUND AND TAKES A QUARTER-BILLION IN ORDERS Aptera Motors announces it has closed its round of Series A funding, accepting a total of over $4 million. Aptera’s continued momentum has now garnered it over 7,000 vehicle reservations in just over two months totaling a quarter-billion in orders. The Solar Electric Vehicle (SEV) company is backed by crowdfunders, private investors and automotive leaders such as Sandy Munro of Munro & Associates, Inc. Earlier this month, Aptera moved into a new production design facility in the Sorrento Valley area of San Diego. Part of a 60,500 square foot campus, the facility will be home to Aptera’s three completed vehicles and a team of development engineers. Areas of focus will be advanced 3D printing, composites, UI/UX development, and battery technologies development. As the company expands, Aptera will be evaluating additional locations for production facilities in San Diego and around the world. https://www.aptera.us/post/aptera-closes-4m-series-a-round-and-takes-a-quarter-billion-in-orders ULTIUM CELLS CELEBRATES COMPLETION OF STEEL BUILDING STRUCTURE "Ultium Cells, the battery joint venture between General Motors and LG Chem's LG Energy Solution in Lordstown, Ohio, celebrates the completion of the steel building structure after 10-months and 500,000 construction build hours. About 85 members of Ironworkers gathered to sign the final beam of the structure, which in the near future will turn into a 2.8-million-square-foot plant." according to InsideEVs: "The site will be completed by mid-2022 and be able to produce 30 GWh of lithium-ion battery cells annually (with an option to expand), employing more than 1,100 people. GM and LG Chem agreed to jointly invest $2.3 billion in the venture to secure lithium-ion cell supply for the entire range of new electric vehicles." https://insideevs.com/news/489446/ultium-cells-celebrates-construction-milestone/ https://media.gm.com/media/us/en/gm/news.detail.html/content/Pages/news/us/en/2021/feb/0219-ultium.html PEUGEOT BEATS RENAULT IN FRANCE "Looking at January best sellers, the Peugeot e-208 has beaten the Renault Zoe for the first time since last April, and adding insult to injury, it wasn’t the only Peugeot model to beat the Renault model!" says Clean TEchnica: "The crossover Peugeot 3008 PHEV became the first plugin hybrid to win the monthly best seller trophy in France, by beating both the Zoe and its e-208 sibling. That was thanks to a record 1,410 registrations. The result also meant a historic one-two win for Peugeot at home, relegating the Renault EV to the 3rd spot for the first time in 8 years! But one shouldn’t read too much into these numbers, as they had more to do with allocation issues than actual demand. After all, in January, the Renault Zoe’s deliveries were exhausted by the “all hands on deck” effort of December, as Renault did everything to keep the Zoe on the top of last year’s European leadership scoreboard. " https://cleantechnica.com/2021/02/19/peugeot-beats-renault-in-france-ev-sales-report/ http://ev-sales.blogspot.com/ VIRGINIA TO BECOME THE NEXT ZERO-EMISSION VEHICLE STATE "The Virginia Senate has passed a bill that would establish California-style clean car standards in the state. The bill, HB 1965, creates low-emission vehicle (LEV) and zero-emission vehicle (ZEV) programs. It will strengthen regulations on tailpipe emissions, and require automakers to sell a certain number of ZEVs in Virginia." according to Charged EVs Magazine: "Governor Ralph Northam is expected to sign the bill into law. Once he does, Virginia will join 12 other states and Washington DC in adopting LEV and ZEV rules. Minnesota, New Mexico and Nevada are in the process of implementing clean car programs." https://chargedevs.com/newswire/virginia-to-become-the-next-zero-emission-vehicle-state/ https://environmentamerica.org/news/ame/statement-virginia-state-senate-passes-vital-clean-cars-rule VW ID.4 AT US DEALERS IN MARCH "Just got a call from my dealership’s EV specialist. He said my 1st Edition ID.4 would be at the dealer by the end of March and the display models would be there a few days before. I’m still 90% sure the ID.4 is what I want. Drove the Model Y and loved the speed and handling but the frameless glass (breaks easily) and no CarPlay or other streaming services or XM, PLUS the notorious build quality and much higher price unless they get the tax credit back put me off. Also got an insurance quote on the ID and it’s lower than my Mazda3 by a bit. Tesla’s are very expensive" https://www.vwidtalk.com/threads/just-got-a-call-from-my-dealership%E2%80%99s-ev-specialist.989/ NEW QUESTION OF THE WEEK With my 1000th podcast around the corner, what kind of media coverage do you want in 2021?
